300 to 1,000 bar. This enormous force is applied to press the aluminium material in high-pressure die casting, nearly tearing up the material. This is not without consequence. If, for example, profiles have to be joined by welding, the air included in the form of blisters causes significant problems.
The gentle sand casting method convinces with even filling of the mould with very low turbulence. Cooling can be adequately controlled. Processing through welding at a later stage is possible without any problem.
