4 Types of Injection Molding for Medical Device Manufacturing

Updated: Mar 29, 2023

The engineers at In’Tech Industries have provided medical device manufacturers with precision injection molding for more than 30 years. We use lean manufacturing technologies and strategies at our ISO-certified facility to ensure your components are fabricated to the highest standards, even you’re your parts require extremely tight tolerances.

Our injection molding experts will work with you to design, develop, and manufacture precision-molded thermoplastics. Here is a look at the four primary types of injection molding we offer for medical device manufacturing.

Micro Molding

Medical devices contain tiny components that must be precisely engineered and fabricated. At In’Tech, we use a micro molding process to create very small, detailed parts to tight tolerances. We have fabricated micro molded parts for use in surgical devices, hearing health devices, and other applications that include tiny yet essential components. Our process can accommodate parts that are less than 5 thousandths of an inch.

Overmolding

Many medical devices contain overmolded components. Overmolding is a process where a material is molded over another material. First, the In’Tech team fabricates the base layer. Then, we add one or more plastic layers on top of that base layer. These layers bond together to create a single, finished product.

Overmolding is a cost-effective solution that can reduce production overhead, however, it is a precise process that can lead to defects when done incorrectly. You can trust the In’Tech experts to deliver an overmolding part that is free from distortion, stress fractures, or melt.

Reel to Reel

Reel to reel injection molding is a precise process that allows you to combine metal and plastic components into a single composite part. Reel to reel molding allows us to automate production for a hands-off operation that reduces human error. It is an efficient process that can accommodate the most advanced cell designs and configurations.

Insert Molding

Like reel to reel, insert molding can combine plastic and metal components into a single part. It is a type of overmolding process that inserts a metal component into the injection mold, then injects plastic around the insert. Insert molded parts have the strength and connectivity of metal parts and the wear resistance and weight reduction of plastic parts.

If your medical device requires small parts made to the tightest tolerances, get in touch with the engineers at In’Tech today. We can recommend one of our injection molding processes and help you design and fabricate components to the highest standards for quality and durability.
