Tooling supporting Core Pins

Tip Bushings

Tooling utilized to support the end of a Core Pin in a injection mold.
Explore the possibilities of these tools produced from CraftAlloy Tungsten Carbide.

Work with Crafts engineering team to design and produce the most advanced Tip Bushings on the market.

Design interface and material choice are critical, especially when harnessing Tungsten Carbide for Tip Bushings.

Key Benefits – Solve Mold Defects:

  • Maximum Wear Life
  • Superior Design; when harnessing Tungsten Carbide Gate Bushings

Tooling utilized to control the flow of molten plastic into the mold. While also commonly possessing dual use features that mold the plastic part.

Partner with Crafts to achieve results in the mold that were not thought possible.

Key Benefits – Solve Mold Defects:

  • Maximum Wear Life
  • No Wear; even when using the most abrasive forms of plastics.


Crafts Technology engineers and manufactures high precision, complex form, CraftAlloy™ tungsten carbide core pins, inserts, ejectors, and other injection molding tooling with the exacting level of tolerances and design features that high-precision part molders require.

The tooling is harder and more rigid than any other mold tooling material on the market, significantly reducing core shift/deflection, which allows for the highest possible precision and repeatability with injection molded parts.

To further advance this technology, Crafts Technology balances the hardness and rigidity of CraftAlloy™ tungsten carbide tooling by incorporating a metallic cobalt binder, which imparts a level of ductility that produces a very robust tooling system.
CraftAlloy™ tungsten carbide tooling is primarily used to produce high precision molded parts, as the material typically allows for higher molding speeds due to its superior heat transfer characteristics.

Rounding out the advances that CraftAlloy™ tungsten carbide material regularly presents to molders is the overall wear life of tungsten carbide tooling. Molders of components molded from Peek and glass-filled type materials have experienced significantly improved wear life of their tooling when migrating from steel and copper alloys to tungsten carbide.

Maximize Repeatability

Optimal repeatability is made possible by the absolute minimization of tooling deflection during the molding process, specifically due to the rigidity of the CraftAlloy™ tungsten carbide core pins. With thermal heat transfer capability similar to beryllium copper, but without its health hazards, tungsten carbide core pins deliver both maximum cooling capabilities and minimal cycle times.
