K1 Vacuum Valves (hydraulic operated)

One of the biggest issue in light metal die casting is porosity. HERCO and its partner Heck & Becker are able to provide the solution. The Heck&Becker K1 Vacuum Valve is the key.

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
Highly developed geometry of the seal pin achieves the best possible seal in the vacuum system
Cooled hydraulic system for use in hot environments
Easy installation in the die

K1 Chill Vents – Blocks

HERCO supplies the Heck&Becker K1 Chill Vents-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
Disposal as pressure or vacuum venting plates
No ejectors, no cooling and no spraying required

3D Cooling

Homogeneous surface temperature
Reduces the mechanical tension
Increases lifetime
Considerably reduces the cycle time
Cooling bores no longer needed

Copper Cartridge Cooling

The copper cartridge is pressed into the cooling bore: copper remains in contact steel
Close to the contour with a distance of 20 mm from the mold cavity
The risk of a “water shot” is minimized
If a defect in the steel should arise, the cooling remains unaffected due to the additional layer of copper
