High 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.

The High-Pressure foundry currently has 22 die-casting machines, all but one manufactured by Buhler. These range in size from 100 tonnes to 2000 tonnes locking force, and the majority have Wollin automatic die sprayers and strikomat dosing furnaces.

Two recently purchased Buhler SCD 84 LV machines have heavy duty robots extracting and manipulating castings.

Trimming presses are located alongside the die casting machines reducing the amount of movement, encouraging lean manufacture.

Vacuum die-casting has been developed in house and as a result gives Dyson Diecasting major advantages over our competitors for producing technically challenging components.
