High-pressure die casting (HPDC) is particularly suitable for high production rates, and it is applied in several industrial fields; actually, approximately half of the world production of light metal castings is obtained by this technology. In the HPDC of aluminum alloys, cold-chamber die casting machines are typically used, in which the metal injection system is only in contact with the molten metal for a short period. Liquid metal, maintained in a holding furnace at a desired temperature, is generally ladled (or metered with some other method) into the shot sleeve for each cycle. Several operations are involved in the whole HPDC process, from the spraying and blowing out the die to the opening and closing of the die, even if the main steps are the filling of the shot chamber, the injection of the metal into the die, the solidification and the further extraction of the casting. Therefore, the HPDC is a complex process, not only due to the phase transformation the metal undergoes when solidifying in the die.
These machines are equipped with the manual loading of the material and we are planning to purchase Robots for loading the material, spraying the tool, and removing the parts. This automation level gives the advantage of higher productivity and better process control. we are producing a wide range of products with these machines.
We are equipped with two cold chambers high pressure die casting machines :
