DIE CASTING:
Die casting involves preparation of components by injecting molten metal at high pressure into a metallic dies. It is also known as pressure die casting. Narrow sections, complex shapes, fine surface details can be produced by using this casting process.
The dies have two parts. 1st one is a stationary half (cover die) which is fixed to die casting m/c. The other one is a moving half (ejector die) which is moved out for extraction of casting. At the starting of the process, two halves of the die should be placed apart. The lubricant is sprayed on die cavity and then the dies are closed and clamped. The metal is injected into the die. After solidification, the die will be opened and the casting will be ejected.
