Micro Injection Molding for Premium Medical Devices

Micro Injection Molding

Advanced medical micro injection molding and conventional injection molding are very different.

Here are some of the key differences in technology and special controls that are unique to advanced medical micro manufactung:

 

Utilizing Specialized Injection Molding Equipment

MTD has invested in and customized top-of-the-line equipment that is much more specialized than conventional micro injection. Among the many advantages of this advanced equipment is maximizing the efficiency for our process engineering team to develop the widest process window possible.

Dependable and accurate equipment is essential when working with such small numbers. As a matter of fact, our machines have plunger resolution of .03mm. That means that this small measurement—25% of the diameter of a human hair—on position is the difference between a full shot, short shot, or a flashed shot.

 

In-Line Inspection Systems

By implementing in-line inspection systems, we are able to verify the absence or presence of details down to .0001”. This allows our clients the peace of mind that every part is 100% correct.

 

Process Monitoring & Control Systems

Another line of defense that we employ is RJG eDart that speeds the visual inspection process up and can tighten the window on how a cavity is packed, sort from good and bad, and predict dimensions. We have developed this software for micro molding components to where it can actually predict what a dimension will be by assessing how cavity pressures impact particular dimensions.

 

 

Our Micro Injection Molding Process in Action:

first-shot success rate

MTD is a medical micromolding manufacturer with all in-house tooling and injection molding under one roof.

The advantage?

Most of our molds are small and can be carried in your hand. When there’s a molding problem, the molding engineer brings the mold himself to the tooling department. He and the tooling engineer look at it under a microscope—the only way to see the micro features in these molds—and create a solution together.

As our president, Dennis Tully, says, “I don’t know how you can get that collaboration with an outside moldmaker.”
