Die Casting Manufacturing Process


We propose the prototype production method best suited to the customer's requirements.


Manufacture of die cast products begins with the design of the die. Die designers, die engineers and casting engineers collaborate to decide on best procedures, the design being completed quickly and accurately by computer.


Based on the design blueprint, state-of-the-art machine tools and proprietary technologies are used to create the highly precise die.


The die is placed in the die casting machine, and molten alloy fed in at high speed and under high pressure, instantaneously creating the die casting.


This is then machined, surface treated and assembled according to customer requirements.


Precision testing is conducted at each processing stage, including the 3-D measurement of the product's dimensions, allied with X-ray and strength testing.
