Mold Types and Job Work Capabilities
Our toolroom manufactures Class 101, high-cavity, insert, and unscrewing molds, and provides EDM and insert machining as job work.
Class 101 Molds
Molds built for very high-volume production, constructed from hardened steel for long tool life.
High-Cavity Molds
Molds with multiple cavities that produce several parts in every molding cycle.
Insert Molds
Inserts of metal, plastic, or filter material are positioned in the mold and molded into the part.
Unscrewing & Multi-Function Tools
Molds for threaded parts, using built-in unscrewing mechanisms to release the part from the mold.
EDM & Insert Machining Job Work
Spark EDM, wire-cut EDM, and insert machining provided as job work for customer projects.

How a part is checked
Incoming Material Inspection
Materials and components are checked against the order and drawing when they are received.
In-Process Inspection
Dimensions are measured at set points during manufacture, so deviations are found and corrected early.
Tool Trial Inspection
Sample parts from the trial run are measured against the drawing before the tool is approved.
Final Inspection
Finished tools and parts are measured against the drawing and approved before dispatch.
