Vents should be placed at the last place to fill and in areas where weld lines occur. If the mold setting is from a previously successful part, check the original setup conditions. Place vents at last place to fill and at converging flow fronts Increase size of the vents.

These parts can be molded with assembly features in place to reduce product fabrication and secondary operations. For example, when load or tension is placed on a composite longitudinally (in the direction of the fiber), the fiberglass reinforcement is resistant to the loading. The greater ratio of fibers placed in the direction of the load increases the tensile modulus of the laminate.

A Great Place to Work With all the time, effort and resources we invest to build our culture and support our associates, we have been honored to receive awards that showcase our company and people. In 2022, we were very proud to be certified as a Great Place to Work® by the Great Place to Work Institute.
