Tungsten Carbide Core Pins Reduce Core Shift and Deflection

Crafts Technology engineers and manufactures CraftAlloy tungsten carbide core pins, inserts, bushings and other injection mold tooling. 

According to the company, CraftAlloy tooling is more rigid than other mold tooling materials on the market; it reduces core shift and deflection, which reportedly allows for the highest possible process capability (Cpk) with injection molded parts.

While high precision is the primary utility of CraftAlloy tungsten carbide tooling, the material typically allows for higher molding speeds due to the superior heat transfer characteristics of tungsten carbide. Crafts Technology says the combination of the tooling’s high rigidity and better heat transfer allows molders to improve the process parameter range.

CraftAlloy tungsten carbide tooling also features improved overall wear life. Molders of components molded from polyetheretherketone (PEEK) and glass-filled type materials have reportedly experienced significantly improved wear life of their tooling when migrating from steel and copper alloys to tungsten carbide.

According to Craft Technology, typical core pin applications include a wide variety of precision molded commercial products, electrical connectors, household goods and medical consumables such as blood collection tubes, pipette tips, luer lock syringe barrels, laboratory consumables, viral transfer media, plungers, inserts, glass-filled plastic resins and more.
