Hydraulic Operated Vacuum Valve

One of the biggest issue in light metal die casting is porosity. Heck & Becker’s vacuum valve is the solution. Heck & Becker is a partner of HERCO.

Benefits of the Heck & Becker K1 Vacuum Valve:

  • Rejections due to porosity are drastically lowered
  • Excellent surface quality of products
  • Product density and strength are increased
  • Larger, thinner, and more complex castings are possible
  • Flash is reduced or eliminated
  • Low cost of initial investment
  • Low cost of maintenance
  • High volume of air evacuation

HERCO supplies chill blocks that increase your product quality and reduce scrap due to porosity. The innovative washboard design provides high thermal conductivity and high wear as well as temperature resistance. In turn, this allows maximum venting efficiency until end of cavity filling and guarantees the solidification of aluminum or magnesium.

  • Eliminates porosity
  • Reduces scrap rates
  • Increases productivity
  • Minimal maintenance
  • Increases product density and strength
  • Maximum venting efficiency until end of cavity filling
  • Reliable in operation
  • Low initial cost of investment
  • Low cost of maintenance
  • Easy to operate

Copper Composite Inserts by HERCO provide the latest technology in cooling and tempering molds for high pressure die casting. Steel forms the mantle of the mold core, ensuring protection against wear and mechanical stability while copper, located in the interior of the mold core, carries out the dissipation of heat. In conclusion the combination is a steel core that conducts heat like copper. These copper composite inserts can be kept much cooler than steel alone, resulting in 2-3 times higher heat removal and shorter cycle times.
