Medical Micro Molding

Micro injection molding is a specialist process, and medical device and drug delivery device OEMs that are looking for a micro molding partner must select carefully. It is vital that the partner you choose has the business acumen and experience necessary.

Isometric Micro Molding has over 100 years of combined experience in micro injection molding. We have absolute confidence in handling and successfully completing any manufacturing challenge involving micro features, micro components, and micro assemblies. We have the expertise to ensure project success.

Micro Mold Manufacturing

We provide a complete end-to-end solution for precision component design and micro mold manufacturing. Uniquely, we are able to fulfill product design and development, process development, tool design and fabrication, micro injection molding, and assembly automation solutions all under one roof. We have a team of engineers, toolmakers, and production staff that all work to reduce and ultimately eliminate the risks associated with the manufacture of the most complex and precise micro molded components and assemblies.

Microns Matter™ Risk Mitigation

We have developed the Microns Matter™ best-practice risk assessment strategy which is used for the development and high-volume production of critical-to-function micro molded devices on behalf of our customers. Mitigating risk is our fundamental goal, and we use state of the art equipment and process validation tools to ensure success. We adhere to an engineering-based strategy of plan, plan, plan, and then execute.

Complex Feature Micro Molding

Tooling is the key enabling technology when it comes to the success or failure of a micro injection molding project. Often, medical device OEMs find themselves working with medical micro molders that do not take a holistic view of the design and manufacturing process, and do not understand the absolute importance of an expert tooling program.

Isometric Micro Molding has precision tool making at its core. This, along with a complete understanding of all the aspects of micro design and manufacturing, means that we are able to manufacture extremely accurate medical device parts and components from high performance polymers with the following complex features.
