Governor Spool for Electrical Motor Industry

Governor Spool for Electrical Motor Industry

Woodland Plastics partnered with a manufacturer of electric motors to mold these governor spools used within electric motor applications. Using a 250-ton thermoset molding machine, Woodland Plastics molds the parts in an 8-cavity tool using injection molding process.

Because these parts require high dimensional stability and strong electrical properties, the material chosen to mold these parts is a graphite-filled phenolic resin from Plenco. After molding, the finished parts are post-baked in an oven for final curing, and then deflashed in an automated wheelabrator before being dimensionally inspected by quality and then shipped to a customer plant in Texas.
