Medical Device Injection Molding Experts
Medical Plastic Injection Molding for the Medical Manufacturing Industry
PMC provides medical plastic injection molding for components used in end-use medical devices. We also provide medical plastic molding for complex assemblies within different systems.
Materials & Processes
Engineered plastic resins are selected for physical properties, such as strength and resistance to chemicals, as well as cost and manufacturability. Medical devices involve molding processes, as well as multiple fabrication processes.
Additionally, materials may be selected for biocompatibility and excluded when they involve plasticizers, such as phthalates.
Advanced medical injection molding processes are often used for cost-effective production. Product identification and control will benefit from in-mold decoration, pad printing, and other post molding operations.
Medical assemblies can be delivered with different materials through multishot molding and overmolding. Components that require further assembly can be supplied with inserts and gasketing.
Certain medical applications require sub-micron filters, which can be molded into a supporting structure.
Silicons are often used in medical devices because of their very low solubility and ability to withstand high temperatures and chemicals.
Special Considerations
Medical plastic injection molding requires the highest attention to both quality control and cost savings.
Our years of experience with molding dynamics and shot control allow us to deliver consistent results, even with multi-cavity molds and long production runs.
When a medical device involves additional assembly stages, we can also accommodate that work in our facility. That means an entire product can be produced from resin to finished goods under the same roof. We can provide plastic welding, fasteners, and we can control the supply chain for customer-specified components.
Many customers prefer to outsource the assembly of specific components to PMC instead of developing their own production facility. This allows them to allocate capital and floor space to other operations and lets them turn a fixed expense into a variable cost, saving inventory and purchasing costs.
How to Get the Best Results
Partner with PMC early in the development process. We can help select the best-engineered resin for medical molding, product performance, and manufacturability.
In many cases, multishot molding and in-mold decoration can help control assembly costs and make for a better product.

Medical Overmolding & Multishot Capabilities
We offer custom overmolding and multishot molding solutions for assemblies that require multiple materials in a single component. This technique improves ergonomics, enhances sealing, and reduces assembly steps. Our team can help integrate TPE, silicone, or other elastomers over rigid substrates, ideal for handheld instruments or seals requiring a soft-touch grip. Contact us early in development to optimize part design and resin compatibility.

Insert Molding & Medical Assembly
Reduce time, waste, and secondary operations with precision insert molding. PMC can integrate metal fasteners, filters, or threaded components directly into the molded part, eliminating manual assembly and boosting product durability. For complete sub-assemblies, our facility offers component sourcing, ultrasonic welding, and final assembly solutions, helping streamline your supply chain under one roof.

Frequently Asked Questions About Medical Injection Molding
What is medical plastic injection molding?
Medical plastic injection molding is a precision process used to create safe, reliable plastic parts for healthcare applications. At PMC, we specialize in complex geometries and medical-grade materials that meet FDA and ISO standards. To discuss your specific part requirements, contact our team.
What types of medical devices can PMC support?
We mold components for surgical tools, housings, pumps, diagnostic devices, and filtration assemblies. If you’re unsure whether your product is a fit, reach out to our experts for guidance.
Are all parts manufactured in the U.S.?
Yes. All of our medical device injection molding work is done in our Wisconsin facility. This gives our partners greater control over lead times, quality, and supply chain security. Learn more by getting in touch here.
Do you offer cleanroom-compatible molding?
We produce parts that are compatible with cleanroom assembly and sterilization, though we do not operate an in-house cleanroom. If your application has specific environmental needs, contact us to discuss the best-fit solution.
What materials are used for medical plastic molding?
We work with FDA-approved and biocompatible resins, including polypropylene, PEEK, polycarbonate, and silicone blends. Our engineers will help you choose the right resin for function, cost, and compliance. For material recommendations, start a conversation with our team.
Can PMC help during early product development?
Absolutely. Collaborating early helps us improve part design, reduce costs, and speed up production. Our engineers provide material selection, DFM feedback, and prototyping support. To get started, request a consultation.
