Low to mid-volume zinc castings using low-cost machined graphite permanent molds
Castechnologies’ exclusive graphite mold process produces zinc aluminum castings with a die cast surface finish, excellent tolerances, and low part cost.
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.
Cast precision (+/-.005) to near-net-shape, which reduces secondary machining and cost
Cast surface finish of 125 RMS or better
Bearing qualities superior to bronze
Tooling lead times of 3-6 weeks, depending on mold shop backlog
Reduced internal voids
Zinc Aluminum Alloy ZA-12 material properties:
Non-magnetic (suitable for electronic shielding)
Castechnologies offers complete machining and finishing services including: chromate, polymeric coatings and paint (polyurethane, powder, e-coat, etc.).
