A few particularly relevant Texas specialists

For a startup going from prototype → FDA → production: Biotex, AJ Medical, DesignPlex, or Velentium.

For active/electronic devices: Velentium is particularly relevant because of its electrical, mechanical, firmware/software, systems-engineering, and manufacturing capabilities.

For plastics/injection molding: SigmaPro or Taurus Engineering. Taurus advertises ISO 13485/FDA-registered manufacturing, Class 7 cleanroom molding, insert molding, over-molding, and in-house mold making.

For catheters, tubing, molded components, and minimally invasive devices: Rose Medical is another Texas option, with catheter lamination, wire-reinforced cannula, injection/silicone/dip molding, laser processing, assembly, packaging, and sterilization validation.

For sterile/single-use devices: PRO-TECH, Mainstream, Rose Medical, and Coastal Life Technologies are worth investigating. Thomasnet identifies Coastal Life in San Antonio as providing contract manufacturing of sterile and single-use surgical devices plus assembly and packaging.

What I'd compare before selecting one

For a serious RFQ, I'd ask each manufacturer for:

1. ISO 13485:2016 certificate and scope
2. FDA registration and relevant device-manufacturing experience
3. Whether they support design transfer/DFM or only build to drawings
4. Experience with your device class and technology
5. Cleanroom classification and environmental controls
6. Validation capabilities: IQ/OQ/PQ, process validation, sterilization, packaging
7. In-house vs. outsourced machining, molding, sterilization, and testing
8. Minimum production volumes and ability to scale
9. Regulatory/documentation support
10. Ownership of tooling, fixtures, drawings, and process IP
11. Typical NPI/production-transfer timeline
12. Quality metrics, CAPA/SCAR process, and audit history

If you tell me what kind of device you're manufacturing (e.g., Class II disposable, orthopedic implant, catheter, surgical instrument, diagnostic/electronic device), expected annual volume, and whether you're at prototype, 510(k), or commercial-production stage, I can narrow this to the most relevant 5–7 Texas manufacturers and compare their capabilities side-by-side.

If you mean Texas-based contract manufacturers that are genuinely experienced with orthopedic implants, surgical instruments, and regulated medical-device production, I’d put the following companies on the shortlist. I’m using “best” here to mean strongest documented fit for orthopedic/surgical OEM work, not a subjective overall ranking.

Strong Texas candidates

• Banister Medical (fka Banister Tool) — Pflugerville/Austin area
  Particularly relevant for tight-tolerance orthopedic implants and surgical instruments. Its capabilities center on precision machining and complex medical components, making it a good candidate for screws, instruments, implant components, and assemblies.
• A R Fabricating — Georgetown
  A smaller, specialized manufacturer whose ISO 13485 scope specifically covers spinal implants, surgical instruments, and medical-device components. That makes it particularly interesting for spine and orthopedic startups that want a more hands-on manufacturing partner.
• Skeletal FX Manufacturing — Leander
  Focused on medical-device/implant manufacturing, with particular association with orthopedic joint and spine products. This is worth investigating for precision-machined implant programs.
• Mainstream Medical Devices — Austin
  Especially relevant for single-use surgical instruments and accessories, including products such as drill bits, reamers, needles, handles and knives. It also provides packaging and sterilization coordination, which can be valuable when the OEM wants more than machining alone.
• AJ Medical Manufacturing — Houston
  A broader design-to-manufacturing partner offering engineering, prototyping, assembly, welding and other services. It could be a good fit when you're still transitioning a surgical device from development into commercial production.
• Viant — San Antonio
  A much larger medical-device manufacturing operation. The San Antonio facility supports complex assemblies and finished-device manufacturing across areas including orthopedics and surgical technologies.
• West Coast Surgical — Houston
  More focused on surgical instruments and instrument subassemblies, with machining, inspection, cleaning/passivation and traceability capabilities. Worth considering for instrument-heavy programs.

Companies I'd also investigate

Tecomet deserves special attention if you're looking for a major orthopedic-focused supplier rather than a small machine shop. Tecomet describes itself as the largest contract manufacturer serving the orthopedic industry, with capabilities spanning forging, casting, machining, additive manufacturing, finishing, cleanroom assembly and sterile packaging. Its orthopedic coverage includes large joints, spine, extremities/trauma and CMF.

Schivo Medical is another strong fit for sophisticated programs. It specifically lists orthopedic implants alongside minimally invasive, robotic, cardiovascular and neurovascular devices and offers vertically integrated components, subassemblies, assemblies, validation and packaging/logistics.

Autocam Medical is particularly relevant if the requirement is precision-machined implants and instruments—including screws, plates, drill bits, drivers, cutting tools and handpieces for spine, hip/knee, shoulder, extremities and CMF.

How I'd segment the Texas market

One important distinction: Texas has a lot of medical-device manufacturers, but considerably fewer that I'd consider true orthopedic OEM contract-manufacturing specialists. Texas's own economic-development materials identify orthopedics as one of the state's major medical-device clusters.

If you tell me what you're manufacturing (e.g., spine implants, trauma plates/screws, arthroscopy instruments, robotic instruments, disposable instruments) and your approximate annual volume, I can narrow this to 5–7 Texas suppliers and compare their likely capabilities, ISO/FDA credentials, geography, size, and prototype-to-production fit.

If you mean Texas-based contract manufacturers that can actually produce orthopedic implants and/or surgical instruments for an OEM, rather than general machine shops, I’d put the following on a serious sourcing shortlist. I’m not treating “best” as a universal ranking; the right choice depends heavily on implant type, volume, materials, and how much engineering/finishing you want outsourced.

Strong Texas candidates

• Banister Medical (fka Banister Tool) — Pflugerville/Austin area. Particularly relevant for complex orthopedic implants and surgical instruments. Its capabilities include 5-axis machining, CNC turning, Swiss machining, and tight-tolerance multi-component assemblies. This looks especially interesting for precision machined metal implants and instruments.
• A R Fabricating — Georgetown. A smaller, specialized medical-device manufacturer with ISO 13485 certification, explicitly focused on spinal implants, surgical instrumentation, and orthopedic prototype/production work. Its boutique scale could be attractive for development programs, prototypes, and lower-volume production.
• Precisto — Carrollton. Offers a broader OEM/contract-manufacturing model covering implants, surgical instruments, testing assemblies, and custom device components, with ISO 13485:2016 and ISO 9001 certification. It says it can take projects from development through manufacturing, assembly, testing, and shipment.
• Skeletal FX Manufacturing — Leander. Worth investigating for orthopedic joint and spine implant work and precision machining. Its medical-device operation is associated with implant manufacturing, including orthopedic joints and spine.
• AJ Medical Manufacturing — Houston. ISO 13485/FDA-registered contract manufacturer offering engineering, medical-device manufacturing and assembly. It may be more compelling when you need a broader design-to-production partner rather than machining alone.
• West Coast Surgical — Houston. More instrument-oriented: CNC milling/turning and Swiss machining, with capabilities aimed at surgical instruments and instrument subassemblies.

If you're willing to use a national supplier with Texas operations

There are also substantially larger orthopedic contract manufacturers worth considering:

• Vantedge Medical — specializes in orthopedic components and surgical instruments, including bone screws, spinal implants, fixation systems, plates, drivers, taps and drills. It also offers finishing, assembly and in-house Ti anodizing, with ISO 13485/FDA-registered facilities.
• ARCH Medical Solutions — large-scale medical OEM supplier with orthopedic implants, spine/surgical instruments, precision machining, finishing and assembly. Its published capabilities include hard metals, plastics and exotic metals and prototype-to-production engineering support.
• Orchid Orthopedic Solutions / Tecomet — particularly relevant if you need a vertically integrated orthopedic supply chain. Capabilities include forging, casting, machining, additive manufacturing and implant coatings, covering both implants and instruments.

How I'd narrow the field

One important distinction: if by “orthopedic implants” you mean patient-implantable components (e.g., Ti/CoCr hip, knee, trauma, or spine implants), I'd weight implant-specific experience, material/process validation, surface finishing, cleaning/passivation, traceability, metrology, and regulatory history much more heavily than generic CNC capability. For instruments, cosmetic finishing, complex 5-axis machining, Swiss machining, laser marking, cleaning, and assembly become more important.

If you tell me (1) implant type, (2) material, (3) approximate annual volume, and (4) whether you need instruments too, I can narrow this to a 3–5 company Texas shortlist and compare their capabilities, certifications, location, likely production scale, and fit for your program.

Yes. I found several Texas-based medical-device contract manufacturers that publicly document both ISO 13485 certification and FDA registration. I’d treat the list below as a strong sourcing shortlist, but verify the specific facility/registration and current certificate during supplier qualification because FDA registration is establishment-specific and changes over time.

A few important qualifications

FDA registration is not the same thing as FDA approval. FDA states that domestic contract manufacturers are required to register and list devices when they fall within the applicable establishment categories. The FDA's registration/listing database is updated weekly, so I'd use the FDA database as the final verification rather than relying solely on a manufacturer's website.

Also, ISO 13485 certification is facility/scope-specific. For example, a company can have an ISO-certified QMS while a particular manufacturing process, facility, or product isn't necessarily within the certificate's scope.

One especially relevant regulatory change: as of February 2, 2026, FDA's Quality Management System Regulation (QMSR) became effective and incorporates ISO 13485:2016 by reference.

If you're actually sourcing a CM

I would narrow the above based on the type of device:

• Catheters / minimally invasive devices: Putnam Medical, PDV MedTech, AJ Medical
• Silicone components: SMI
• Single-use instruments/devices: Mainstream Medical Devices
• Complex active/electronic devices: Velentium, Biotex
• Injection molding / polymer components: PDV MedTech, AJ Medical
• Device assembly + packaging: Mainstream, Forward Science, AJ Medical
• Large-scale CDMO / established OEM programs: Seisa

If you tell me what type of medical device you're manufacturing (e.g., catheter, wearable, Class II disposable, implant, surgical instrument, electronic device) and approximate annual volume, I can narrow this to 5–10 Texas CMs that specifically match the process and volume requirements, including their locations, cleanroom classes, certifications, FDA registration status, and contact/website information.

Places ChatGPT showed

• Integer Holdings, LLC · 5.0★ · Medical technology manufacturer
• DesignPlex Biomedical LLC · 5.0★ · Corporate office
• Sigmapro Engineering and Manufacturing · 4.4★ · Manufacturer
• PRO-TECH Design & Manufacturing · 5.0★ · Manufacturer
• Strukmyer Medical · 4.3★ · Medical equipment manufacturer
• Scapa Healthcare/Biomed Labs · 4.5★ · Medical equipment supplier

If by “reliable” you mean established medical-device CMs with strong quality/regulatory infrastructure, the DFW market has several credible options. I’d shortlist these based on ISO 13485, FDA-regulated experience, breadth of manufacturing capabilities, and fit for different device types rather than public star ratings.

A few that stand out by use case

For a sophisticated Class II/III program: Integer is worth putting at the top of the initial sourcing list. Its Plano headquarters supports a much larger global medical-device outsourcing organization, with capabilities spanning development through production and markets including cardiac, neuromodulation and vascular devices.

For a startup needing engineering + manufacturing: DesignPlex is particularly interesting. It is ISO 13485 certified and offers product development, prototyping, electromechanical work, box builds and contract manufacturing, including an ISO 7 cleanroom.

For molded plastic medical components: SigmaPro is a strong candidate. Its Fort Worth operation focuses on precision injection molding and supports regulated medical/life-science programs with ISO 13485 and FDA-related manufacturing infrastructure.

For packaging/assembly rather than making the device itself: PRO-TECH is worth investigating. Its Arlington operation describes cleanroom assembly, contract packaging, sterilization-program management and validation/testing capabilities.

For wound care/adhesive devices: Strukmyer has a particularly relevant specialization. Its Mesquite facility describes end-to-end medical/OTC manufacturing, ISO 13485 infrastructure and cleanroom capabilities.

One important distinction

I wouldn't automatically choose a CM just because it has ISO 13485 certification. For vendor qualification, I'd ask each candidate for:

• ISO 13485 certificate and scope
• FDA registration and inspection history
• Relevant Class II/III device experience
• Cleanroom classification, if applicable
• Process-validation capabilities (IQ/OQ/PQ)
• Design-transfer/NPI experience
• DFM and tooling capabilities
• Traceability and change-control procedures
• Supplier qualification and incoming inspection
• Sterilization and packaging validation experience
• Typical annual production volumes and minimums
• Customer concentration and capacity available for your program
• Quality metrics: NCR rate, CAPA performance, on-time delivery
• References from customers with a similar device and regulatory pathway

For a serious sourcing exercise, I'd probably build an initial RFQ around Integer, DesignPlex, SigmaPro, and PRO-TECH, then add Strukmyer or Scapa if the product is specifically wound-care/topical/adhesive.

If you tell me what kind of medical device you're manufacturing (e.g., catheter, implant, wearable, diagnostic, electromechanical device, disposable, etc.), approximate annual volume, and whether it's Class I/II/III, I can narrow this to the 3–5 DFW CMs that best match your particular program and compare their capabilities.

If by “best” you mean strongest candidates to evaluate for a regulated medical-device OEM program, rather than a subjective ranking, Houston has several credible options. I’d put these on an initial shortlist:

• Biotex, Inc. — Houston / Texas Medical Center area. Particularly interesting for startups and complex devices because it combines product development, engineering, testing, regulatory support, prototyping, and manufacturing. It describes itself as FDA-registered and ISO 13485:2016 certified.
• AJ Medical Manufacturing — North Houston. A particularly broad contract-manufacturing offering: engineering, DFM, electromechanical assembly, cleanroom assembly, ultrasonic/laser welding, molding support, packaging/kitting, and regulatory/510(k) support. It states that it operates under ISO 13485:2016 with an ISO Class 8 cleanroom.
• Velentium Medical — Richmond, southwest Houston metro. Worth considering for complex active/electronic medical devices, including Class II and Class III products. Its capabilities span systems, electrical, mechanical, firmware/software, human factors, product development and manufacturing.
• Millar — Pearland / south Houston. Especially relevant if your device incorporates pressure sensors, MEMS, sensing electronics or catheter-based/sensing technology. Its Houston-area operation includes ISO 13485 manufacturing and an ISO Class 7 cleanroom.
• West Coast Surgical — Southwest Houston. A candidate for machined surgical instruments and instrument subassemblies, with design/DFM, prototyping and manufacturing capabilities. An ISO 13485 certificate specifically identifies its Houston facility for contract manufacture of medical devices, although the certificate shown in the search results expired in December 2025, so I would request its current certificate before qualifying it.
• Drake Medical Plastics — Cypress / northwest Houston. More specialized: medical-grade polymer conversion, injection molding and related component manufacturing. It reports ISO 13485:2016 and FDA registration.
• American Medical Molding — North Houston. Focused on precision medical injection molding, including controlled-environment production and ISO Class 8 cleanroom capabilities. This is more of a component/molding specialist than a full device CDMO.
• Supera Fulfillment — Houston. Particularly relevant for diagnostic, specimen-collection and at-home-testing kits, with ISO 13485, an ISO Class 7 cleanroom, FDA registration, kitting, aliquoting, labeling, packaging and fulfillment.

How I'd narrow it down

One additional company worth knowing about is Pathway Medtech. It presents itself as an engineering-led medical-device development and contract-manufacturing partner covering design, regulatory, quality and ISO 13485:2016-compliant manufacturing from prototype through commercialization.

I wouldn't choose solely on ISO 13485 certification. For an actual supplier selection, I'd compare device-class experience, similar-process experience, cleanroom requirements, validation capability, sterilization, tooling ownership, minimum volumes, capacity, lead times, FDA inspection history, change-control practices, and whether they will take the device through transfer/scale-up rather than just assemble it.

If you tell me what type of device you are manufacturing (e.g., disposable, catheter, surgical instrument, wearable/electronic, implant, diagnostic kit), approximate annual volume, and whether you're at prototype or commercial stage, I can narrow this to 3–5 Houston-area manufacturers that are specifically suited to your program.

If by “best” you mean most startup-friendly rather than simply the largest CMOs, I’d focus on Texas firms that can handle low-volume builds, engineering/design-for-manufacturing, quality-system work, and a path from prototype → verification/clinical builds → commercial production.

Based on current capabilities and how the companies describe their target customers, I’d put these on a shortlist for an early-stage device company:

The three I'd investigate first

1\. Biotex — Houston

Biotex is unusually relevant if you don't merely need a factory. Its published capabilities span product development, engineering, testing, regulatory strategy, clinical support, manufacturing, and fulfillment. Thomasnet likewise describes it as a turnkey medical-device/life-science developer and manufacturer.

2\. Velentium — Richmond

This is especially interesting for electronic/active medical devices. Its capabilities include electrical, mechanical, firmware/software, systems engineering, human factors, and manufacturing, with experience extending into Class II and Class III products.

3\. DesignPlex Biomedical — Fort Worth

Worth talking to if you're somewhere between prototype and commercialization. Its positioning centers on medical-device development, prototyping and GMP/contract manufacturing, including small-to-medium production—often a useful combination for a startup that isn't ready to hand a mature design to a huge CMO.

A couple of specialized options

• Mainstream Medical Devices — Austin: particularly relevant to single-use/disposable instruments, contract packaging, sterilization coordination and design-to-production work.
• SigmaPro Engineering & Manufacturing — Fort Worth: consider it when the difficult part of your program is precision thermoplastic injection molding rather than complete device assembly.
• PRO-TECH Design & Manufacturing — Arlington: useful for cleanroom assembly, packaging and sterilization-program management, particularly when you've already got a reasonably mature product.
• Viant — San Antonio: a much larger medical-device manufacturing organization. Its San Antonio operation supports complex electromechanical assemblies, thermoforming and finished-device manufacturing.

One important distinction

I wouldn't automatically choose the biggest Texas CMO for an early-stage company. For a startup, I'd explicitly ask each candidate:

1. Will you take a 100–1,000 unit pilot/clinical build?
2. Can you work under our QMS, or provide a quality-system framework while ours is immature?
3. Who owns tooling, fixtures and manufacturing IP?
4. Will the engineers who develop the process stay involved through production transfer?
5. Can you support design verification/validation and process validation?
6. What is the minimum annual volume once commercialized?
7. What happens if we only need 200 units next year?
8. Can you provide Device Master Record/BOM/process-documentation support?
9. What cleanroom classification and environmental controls are actually available?
10. Can you provide references from companies that were at our stage—not just Fortune 500 OEMs?

That last question is particularly important. A CMO can be excellent at producing 500,000 units but be a poor fit for a startup needing 300 devices, rapid engineering iteration and hands-on regulatory support.

There are also some non-Texas companies with Texas operations worth considering. For example, Integer has major medical-device CDMO capabilities and a Plano, Texas presence, while Viant has its San Antonio operation. Integer describes an integrated R&D approach spanning design, prototyping and manufacturing.

If you tell me what kind of device you're developing (e.g., Class II disposable, surgical instrument, catheter, implant, wearable/electronic, diagnostic, etc.), current stage, expected first production quantity, and approximate budget, I can narrow this to 3–5 Texas CMOs that are specifically suited to your situation, including likely fit, capabilities, and what to ask each one.

• A R Fabricating · 5.0★ · Machine shop
• Banister Medical (fka Banister Tool) · Machine shop
• PRO-TECH Design & Manufacturing · 5.0★ · Manufacturer

Yes. If by “trusted” you mean established Texas-based/family-owned manufacturers with medical-device experience, ISO 13485 credentials, and evidence of long-term OEM relationships, there are several worth putting on an RFI list.

Strongest matches

• Biotex, Inc. — Houston. A locally based medical-device development and manufacturing partner supporting design, engineering, prototyping, testing, regulatory work, and pilot/small-scale production. Its ISO 13485/FDA-registered positioning makes it particularly relevant for companies that need more than machining alone.
• AJ Medical Manufacturing — Houston. A medical-device/component contract manufacturer offering design, engineering, automation, injection-molding support, assembly, and manufacturing. It is ISO 13485 and FDA registered.
• DesignPlex Biomedical LLC — Fort Worth. Particularly interesting for Class II/III and active-device programs, with product development, prototyping, engineering and GMP manufacturing capabilities.
• Huck Medical Technologies, Inc. — Jacksonville. A smaller, vertically integrated medical-device developer/manufacturer that supports products from concept through commercialization, including process development, manufacturing and assembly.
• A R Fabricating — Georgetown. A boutique ISO 13485 manufacturer particularly focused on orthopedic/spine implants, surgical instruments and medical-device components.
• Banister Medical — Pflugerville. A specialized precision medical-device manufacturer with machining, finishing, validation and traceability capabilities. This looks particularly relevant for surgical/orthopedic hardware.

Two especially notable family-owned companies

Westconn Precision Technologies is one of the clearest fits. It explicitly describes itself as family-owned, has more than four decades of experience, and combines additive manufacturing and precision CNC machining in one facility. It is ISO 13485 certified and specifically focuses on complex/precision medical devices.

Turnco Tool & Instrument in Georgetown is another strong candidate. It has been family-owned and operated for 45 years, with the third generation now involved in daily operations. It serves medical, aerospace, nuclear and defense customers and maintains ISO 13485:2016 and ISO 9001:2015 certification.

If you need assembly/packaging rather than machining

PRO-TECH Design & Manufacturing in Arlington is worth a serious look. It's family-owned, has more than 40 years in medical-device manufacturing, and specializes in contract assembly, packaging, sterilization management, validation and related services. Its site identifies major medical-device customers and long-term relationships, including a customer relationship extending back to its first year.

How I'd narrow the field

One important caveat: “trusted” is difficult to establish independently because contract manufacturers generally cannot publicly disclose their OEM customer lists. I would therefore treat ISO 13485 certification, longevity, published customer relationships, regulatory history, technical scope, and references from actual OEM customers as better evidence than online star ratings.

If you're looking for a supplier for a specific device, tell me the device type (e.g. orthopedic implant, catheter, surgical instrument, wearable, diagnostic, injection-molded disposable), approximate annual volume, and whether you need machining, molding, assembly, packaging, or full turnkey manufacturing. I can then narrow this to 5–8 Texas firms that are genuinely comparable, including ownership, certifications, capabilities, facility size, and known customer/industry experience.
