High Pressure Die Casting
High pressure die casting is used for items that require precision, and which are to be manufactured in large quantities (from a few hundred to several thousand per year). The tooling is made of steel and is relatively complicated to manufacture.
High pressure die casting processes are usually highly automated, with robots and process control mechanisms. The machine size required for casting any particular item is determined by the amount of moulding force required, the item’s design and the requirements profile. Our smallest machine can develop 160 tonnes and our largest 970 tonnes. Rheocast, a method where we use semi-solid technology, is also a process for which we have the equipment and the knowledge.
How big the machine needs to be to cast a details is decided by how much the pressure from the filling of the empty space wants to push apart the tooling. It’s like a backward hydralic pump, and you measure the machines in locking power (how much they can manage to hold the tooling together). Our smallest machine can develop 160 tonnes and our largest 970 tonnes. The 160 tonner casts details with a weight up to a few hectos, while the 970 tonner can produce 15 kg casting weight.
Since 2007, we have the equipment and knowlegde to produce SSM, SemiSolid Metalcasting. This is a casting methid where we use aluminum in a semi-solified form. It’s also called slurry casting.
