Matrix Plastic Products processes bioabsorbable resins to produce implantable medical devices for our OEM customers. The proper drying of these hygroscopic materials requires specialized knowledge, methods, and equipment critical to maintaining their integrity.

Nylon is an extremely hygroscopic material. If not adequately dried before processing, a number of undesirable physical and cosmetic problems can occur as a result of excessive moisture.

Matrix was one of the first mold shops in the Chicago area to achieve ISO 9001 certification in 1999.  Although we’ve also been ISO 13485 certified since 2010, we continue to maintain our 9001 certificate, and with good reason.


Consulting with a metallurgist yields insight into the causes of corrosion in a mold, and how our injection molding process keeps it at bay.

Matrix Plastic Products actually began as "Matrix Tooling", a specialty mold builder, in 1978.  That tooling tradition continues today as we blend moldmaking craftsmanship with state-of-the-art CNC technology and equipment. It takes the best of both to produce the highest quality molds while meeting our customers’ compressed lead times.  

Apprenticeship in a trade like moldmaking is a viable alternative to the typical 4-year college degree, and a path to career success for those with the talent and inclination to pursue it. 

Somewhere in between the cold runner and hot runner lies the old technology of the insulated runner: a less expensive option for running quick cycle, commodity resin parts with frequent color changes.

Matrix Plastic Products is serious about being environmentally responsible and practicing the 3 R’s: 
Reduce - Reuse - Recycle

This blog is a look back at how molding robotics had evolved at Matrix up to 2008, including the addition of the Flex Teach PC-based programming system.  

Unstructured, or informal, problem solving in injection molding is based on one’s own experience and lessons learned.

Structured, or formal, problem solving tools help identify root causes and lead to solutions as well as process improvements in injection molding.

A continuation of the previous blog on structured problem solving that discusses "Cause and Effect" or "Fishbone Diagrams"
