Low Pressure

Diecasting can produce castings with accuracy comparable to machining tolerances. Typical precision of 0.025mm in 25mm is possible - i.e. 0.1% of the dimension. Equally, once tolerances have been achieved, they are set for life, giving long term production consistency. This has tremendous benefits for automated assembly processes where consistent accuracy is vital.

APL has long been associated with the development of the low-pressure die-casting process. APL operates 15 of its own low pressure stations, capable of producing castings from 0.5kg to 50kg. BAC process control has been added to those machines enabling further standardisation and validation of the reliability of the process.

In addition to the low pressure stations 2 Gima low-pressure die casting machines have recently been installed. These fully programmable units feature a traversing furnace for ease of filing, degassing and metal treatment.
