Molded Parts

We work closely with our customers to understand application requirements and optimize part design to improve performance and manufacturability. Molds are designed to support high output, low scrap and maintenance requirements. Our in-house toolmakers design and build secondary tooling and maintain production molds, including the following:

Injection Molding

The presses used for injection molding are horizontally operated with a unique material delivery system. The thermoset compound is fed and injected with a high speed reciprocating screw or a plunger system that reduces glass degradation for better part strength.

Compression Molding

This molding process utilizes a pre-staged charge of material that is created by manually or automatically cutting, stacking, arranging and weighing the individual SMC or TMC pieces. This charge is either manually or automatically loaded into the open mold. Once the charge is placed, the mold is closed with a fast closing speed followed by a controlled final closure speed once the thermoset compound begins to flow. As the compound flows in the mold, it reaches a telescoping shear edge zone at the perimeter of the cavity that enables air to escape.

Pultrusion

Pultrusion is a manufacturing process used to produce continuous lengths of  composite materials with constant cross-sections. The process involves pulling raw materials (liquid resin mixtures) through a heated steel forming die using a continuous pulling device.

Finishing

Where precision machining is required, we can meet the tightest tolerances – and we have the capacity to meet demanding volume and scheduling requirements, as well. Highly-complex parts and those with extraordinary tolerances can be produced in our three-axis and five-axis CNC machining centers.
