High-pressure die casting
Fully automated high pressure die casting ensures high economic efficiency and flexibility
The high-pressure die casting process involves pressing liquid metal at relatively high pressure into divided metallic permanent moulds. High flow velocities occur in the casting mould throughout the casting process until the mould is filled. The pressure with which the liquid metal flows at high velocity into even the narrowest of spaces is critical for the ultra-precise reproduction of contours.
The methods used in die casting include the vacuum die casting method and the squeeze casting method.
At the five locations in Biberach, Annaberg, Košice (Slovakia), Kechnec (Slovakia) and Tianjin (China), over 90 fully automated cold chamber die casting machines are available with closing forces of up to 4,000 tonnes.
All popular alloys in aluminium and magnesium are processed.
Advantages of high-pressure die casting
- Dimensional accuracy
- Low machining allowance
- Thin walls
- High strength
- Good surface quality
- High productivity due to high automation
- Leak tightness as long as the casting skin is not machined
- Sprue parts possible
For our series production, we use fully automated casting cells with cold chamber die casting machines including robot handling and deburring presses.
