High pressure Zamak die casting
- The Zamak high pressure molding consist in injecting under high pressure a liquid alloy in a metalic mold that solidifies quickly to form a piece
- This process allows the production of thin pieces with complex form with very tight dimensional tolerances, limiting as much as possible the machining resumption
- One of his main advantages is to have a very high repeatability and a very high tool life
Characteristics of the zamak used in high pressure die casting
- The zamak has good mechanical characteristics, excellent flowability and very good dimensional stability
- It allows high production rates
- It also has good decoration and corrosion properties
- Recycling zamak is easy and economical, environmentally friendly

A zamak is considered stabilized after 8 weeks at room temperature. Zinc alloy parts may undergo certain bending, bending, cold-shaping operations, observing certain precautions. Elles peuvent aussi être assemblées par sertissage, bouterollage de collerettes et de parois minces, de rivets et de reliefs divers venus de fonderie. (?)
