Castechnologies uses the Graphite Permanent Mold (GPM) process, which combines the low cost of easily machined graphite molds with a high-strength, highly engineered, zinc-aluminum alloy, ZA-12, to provide an economical alternative to other manufacturing processes in annual volumes of 500 to 15,000. Zinc castings from graphite tooling offer a unique combination of fast, low cost tooling, low part price, and precision tolerances.

Benefits include:

• Cast precision (+/-.005) to near-net-shape, which reduces secondary machining and cost

• Cast surface finish of 125 RMS or better

• Piece-to-piece repeatability

• Bearing qualities superior to bronze

• Tooling lead times of 3-6 weeks, depending on mold shop backlog

• Homogeneous castings

• Reduced internal voids

Zinc Aluminum Alloy ZA-12 material properties:

• Non-magnetic (suitable for electronic shielding)

• Easily machined

• Non-Incendiary

• Spark-proof

Castechnologies offers complete machining and finishing services including: chromate, polymeric coatings and paint (polyurethane, powder, e-coat, etc.).
