The molding components of injection molds consist of cavity, core, and insert parts that shape the internal and external surfaces of plastic products. The cavity forms the outer surface while the core forms the inner surface.

Cavities form the external surfaces of plastic parts and are available in integral, integral embedded, and partial embedded (combined) configurations. Mosaic structures simplify processing of complex cavities, optimize material usage, and utilize gaps for exhaust functions.

Cores shape the internal surfaces of plastic products, available as integral types for small injection molds and combined types for large/medium injection molds.

Specializing in precision mold parts including cavity pins, core pins, punches, ejector sleeves, and CNC machining components manufactured from steel, tungsten stainless, aluminum, and copper materials.
