Why Topworks for your medical injection molding

It is equally important that medical devices work reliably at all times, no matter if they are used daily or in an emergency. There is very little room for error. Designers and engineers need to pay extreme attention to DFM (Design for Manufacturability) and mold flow analysis to ensure precision performance.

Topworks recognizes the importance of bringing medical devices to market quickly while navigating the complex landscape of regulatory compliance. We are constantly expanding our medical manufacturing capabilities.

Medical injection molding is not an easy task. Integrating Quality Management Systems (QMS) for medical device design and manufacturing is crucial. With thousands of options for engineered plastics, it is important to have a medical injection molder with extensive experience in handling medical-grade resins like PEEK, LSR, and Medical PC.

Topworks Plastics has specially trained engineers who can help you select the right polymer to use for your project. We offer solutions to improve properties such as tensile strength, flexibility, transparency, heat resistance (for autoclaving), and chemical resistance.

Medical manufacturers gain immense value by utilizing scientific molding principles that stabilize the production process window. We ensure that our injection-molded components strictly meet or exceed industry standards.

We can adapt to your specific needs with our custom medical molding capabilities. Our highly skilled engineering staff can efficiently adjust the tooling to save time and money, eliminating “trial-and-error” through data-driven decisions.

Your medical plastic component does not have to be finished just because it has been molded. Topworks provides a full range of cleanroom post-molding services, including ultrasonic welding, heat staking, and overmolding. These services consolidate your supply chain and reduce time-to-market.

Factors to consider when selecting medical grade plastics

Medical injection molding operations can be performed with a variety of engineered plastics. Different plastics perform differently depending on their specific polymer structures.

Material options need to be rigorously evaluated based on a number of factors, such as:

Sterilization & Durability:

The selected material must provide the necessary structural strength and survive required sterilization methods (Gamma radiation, Autoclave/Steam, or Ethylene Oxide). For example, if a plastic is going to be subjected to high-temperature autoclaving, standard ABS will fail, and materials like Radel or PEEK must be specified.

Regulatory Compliance (ISO 10993):

In addition to meeting FDA standards, any final component should comply with biocompatibility standards (like ISO 10993 for skin, blood, or tissue contact). The material supplier must provide comprehensive documentation (CoC and CoA) to ensure the final product is safe for patient use.

Chemical Resistance & Working Conditions:

The application environment dictates material choice. Hospital environments frequently use harsh chemical cleaners and lipid-based drugs. The molded component must resist environmental stress cracking (ESC) when exposed to these chemicals.

End-User Ergonomics and Safety:

It is important to choose materials according to clinical usability. An ergonomically designed surgical instrument should be lightweight yet perfectly balanced. Single-use drug delivery products must be functional, intuitive, and fail-safe to prevent needle-stick injuries. At Topworks, we combine advanced material science with precision mold making to deliver components that protect both the patient and the medical staff.
