Medical Plastic Components

Dimensional drift of a few microns can turn a sealed fluid path into a field complaint. It can also delay a submission or trigger costly corrective action. Westec Plastics Corporation manufactures medical plastic components for OEMs that require consistent quality from the first batch through the millionth.

Since 1969, our role has been simple. Our customers have the design intent and regulatory pathway, while we provide the molding expertise and documentation needed to keep their programs moving forward. We aim to serve as an extension of your operation and a trusted supply chain partner rather than an average vendor.

Reach out to us today and discuss your project. Our mold-building, plastic injection molding, and secondary operation capabilities help OEMs bring medical plastic components into production.

Let's Get Started

Part Families We Frequently Manufacture

Some medical plastic components feature thin walls and intricate details. Others require rigid housing that maintains its structural integrity through repeated cleaning and sterilization. Westec Plastics Corporation manufactures part families that span these demands and more, such as:

Diagnostic cartridges and lab consumables
Luer fittings, valve bodies, and other fluid path components
Housings and enclosures for handheld and benchtop devices

Over molded grips and seals with both rigid and soft materials
Surgical instrument handles and single-use device bodies
Drug delivery parts for inhalers and auto-injectors

If you don’t see your component on the list, don’t worry. It highlights our most common projects, not the full range of what we can mold.

Data-Backed Engineering Support

All new programs begin with a DFM review to optimize the tool and avoid downstream issues. During this review, Westec’s engineers assess resin flow, knit line formation, draft for clean ejection, and whether a gate vestige could affect a sealing surface.

Mold flow simulation software helps us get answers so we can collaborate with you on any tool modifications.

Resins Often Used for Medical Plastic Components

Resin selection influences everything from cycle time to sterilization methods, so it is important to make sure you’re choosing the best option for your medical plastic components.

Resin	Medical Plastic Components It’s Used For
Polycarbonate	Clear housing and fluid path components
Polypropylene	Single-use consumables and living hinges
PC / ABS	Device enclosures and handles
COC and COP	Diagnostic and optical parts
PEEK	High-heat parts that need to endure repeated autoclave cycles
Medical-Grade TPE	Soft touch grips, seals and over molds

Partner With Our Molding Professionals for Your Medical Plastic Components

A broad range of devices rely on medical plastic components, including diagnostic equipment, surgical instruments, and drug delivery systems. The most reliable devices share a common thread: the OEM brought the injection molder into the design conversation early.

Collaborating with Westec Plastics Corporation at the concept stage allows our team to review part geometry and tooling strategy while changes remain cost-effective. Later involvement can still add value. Many OEMs reach out to us mid-program to address a tool transfer, capacity constraint, or quality issue with a fresh perspective and proven expertise.

Westec can support your project at any stage. Give us a call today and explore our full breadth of capabilities and quality control measures.
