Capability for the Medical Aids Industry


The nature of injection molding makes it one of the more cost-effective manufacturing processes available. When medical parts, components, and devices are required in bulk, plastic injection molding will almost always be the most cost-effective option.

Exceptional Accuracy

Tight-tolerance production is critical in medical device manufacturing, where millimeters or microns can make a difference in the successful performance of a component. Skilled plastic injection molding facilities can produce high quantities of components and devices with exceptional accuracy and negligible variance from piece to piece.


Many plastics are used in injection molding and offer superior strength and durability, resisting harsh environments, vibration, and blunt force without cracking, breaking, or shattering. Many injection molding plastics also possess the heat resistance needed to be repeatedly sterilized via autoclave and other means.

Contaminant Resistance

The plastic materials used in medical device injection molding are designed to be resistant to contaminants and easily sterilized.

Applied in Medical Aids Industry

The medical plastic injection molding process is ideal for high-volume production and meets the required consistencies and tight tolerances. Cheng Fwa manufactures medical components and devices using medical-grade plastic materials that are durable, reliable, and have ISO 13485 medical equipment certification. With production quality that complies with medical regulations and standards, Cheng Fwa is your reliable supplier.
