Alloys for ZAMAK

The raw material is the most important element in any kitchen of a good restaurant. The same thing happens in centrifugal casting, without a good alloy, you cannot work properly.

CONIEX has been working for more than 30 years to improve alloys and their application in the silicone mold casting sector. When we started it was not possible to melt Zamak in molds at low pressure. The pieces were not filled, there were pores, sinkholes, etc. We had to develop our own alloy which over time has become the industry standard.

With the collaboration of the most important foundries in the world, CONIEX provides metal alloys of guaranteed high quality.

The problems of a low quality zamak

  • Black traces on the pieces
  • Pores
  • Incomplete filling
  • Rejection
  • Low productivity
  • Air bubbles
