CASTECHNOLOGIES uses exclusively the Graphite Permanent Mold process, which combines the low cost of easily machinable graphite molds with a high-strength, zinc-aluminum alloy, ZA-12, to provide an economical alternative to other manufacturing processes in annual volumes of 500-15,000 pieces.

BENEFITS
+ Cast precision (+/-.005), which reduces secondary machining
+ Cast surface finish of 125 RMS or better
+ Piece-to-piece repeatability
+ Bearing qualities superior to bronze
+ Tooling leadtimes of 3-6 weeks
+ Homogeneous castings

MOLDS
The precision molds are designed, then rapidly machined on CNC equipment to customer specifications via CAD-CAM. Mold prices vary according to the size and complexity of the casting but generally cost between $2,500 to $6,500.

MATERIAL
Our castings are produced from a high strength, engineered, zinc-aluminum alloy, ZA12. This alloy is often the first choice when converting from iron, aluminum, brass or bronze.

This alloy is:
+ Easily machined
+ Pressure tight
+ Spark proof
+ Nonincendiary
+ Nonmagnetic (suitable for electronic shielding)
