Micro Injection Molding & Small Part Plastic Injection Molding

The definition of what is considered “Micro” varies—but it generally refers to part size or part feature sizes that are a fraction of traditional parts. Matrix Tool has built a reputation on building extremely high precision, complex injection molds. It was a natural transition for us to pursue Micro Tool Building and Molding capabilities once our customers’ product became increasingly smaller with tighter tolerances.

To be a Micro Injection Molder you have to be willing to step out of the conventional paradigm of modern injection molding technology. Imagine molding 11 parts from a single pellet of resin—then imagine trying to mold that part with a conventional injection molding press. It can’t be done effectively.

Matrix Tool has become our premier small parts molder.

Question Everything…then Question Again

Micro Injection Molding makes you question every aspect of the manufacturing process—and that’s what we’ve done at Matrix. With well over a dozen degreed plastics and mechanical engineers on staff, we have a deep bandwidth of engineering talent who continuously drive innovation. Over 10% of our work staff are degreed engineers! We take a thorough and a systematic approach to Mold design and layout, runner and gate sizes, cavity spacing, total flow lengths, part ejection, inspection and post-molding part handling. That’s what it takes to mold parts that weigh .002 grams or have a gate diameter measuring .075 millimeters!

Overall, Matrix is a world class supplier with excellent technical support, technology and business processes. Matrix is a tremendous partner to have in our supply chain.

The Need For Speed

Two of the major keys to successful Micro Molding is having the right injection molding machines and proper ‘know-how’. Matrix has partnered with Sodick for all of our Micro Molding needs. We utilize Sodick Injection Molding Machines, customized at Matrix, that have a barrel ounce capacity of 0.15-to-0.91 ounces and a tonnage range of 20-to-60 tons.

Known for incredible accuracy, acceleration and deceleration, our Sodick presses deliver best-in-class injection speeds, performance and repeatability. With up to 15.3- G’s of acceleration, our presses inject plastic 10-to-20 times faster than other conventional Injection Molding presses. What does this mean to you? It means we have the capability and ‘know-how’ to efficiently produce product that other injection molder’s continuously struggle with.
