Know How

Melt Flow Rate Testing—Part 5
There are two points in the manufacturing supply chain where a determination of average molecular weight (MW) is important. The first is when the material is first received by the molder. The second is after molding.

Don’t Overlook the Feed Section
Most extrusion screw designers often do not design the feed section with the same rigor as other sections. This is odd since nothing goes through the screw that doesn’t first go through the feed section.

Minimizing Black Specks
Black specks in molded parts are one of the most infuriating problems to resolve on the shop floor. Here's how to fix them.
