Below are pictures of Graphite Permanent Molds and precision, zinc aluminum castings

Precision machined castings are inspected on a Coordinated Measuring Machine (CMM).

The zinc-aluminum alloy, ZA-12, has excellent bearing qualities.  Bores can be machined to size, eliminating the need for pressed in bushings.

Complex features can be cast in the Graphite Permanent Mold Process.

Casting is chromated then painted.

Cast precision makes for consistent, repeatable fixturing in the machining process

Complex features are precision cast with no secondary machining required

While most parts are precision machined on CNC machines, some parts can still be hand ground.in low cost work centers.

Fourth axis CNC machining reduces setups and cost.
