Pattern design is key to a high quality aluminium sand casting

Pattern design is key to a high quality aluminium sand casting

Any new sand casting product requires a pattern. Made from resin, it must be an exact copy of the finished casting in dimensions and shape. It is created by specialist pattern makers to ensure the accuracy of the final product and the quality of its finish.

Degassing in aluminium sand casting

Degassing in aluminium sand casting

Gas porosity may occur if hydrogen is introduced into the molten metal when it is poured into the mould. Hydrogen can be drawn in through moisture or water vapour in the atmosphere. Degassing is used to address this problem and it is carried out as a standard part of the Haworth Castings’ casting process.

Shot Peening in Aluminium Sand Casting

Shot Peening in Aluminium Sand Casting

Shot peening is a finishing technique designed to increase component fatigue life and to reduce cracking in parts operating in high-stress environments. For this reason, it is widely used in the aerospace and automotive industries for safety-critical parts in aluminium sand casting.
