Well!!!!!!!

Investment casting also known as Lost Wax Process is widely used for making intricately shaped components.

Risks:
* Use of Carbon tetrachloride (CTC)
* Long lead time
* Highly Costly

Injection moulding is a manufacturing process for producing parts from both thermoplastic and thermosetting plastic materials. Material is fed into a heated barrel, mixed, and forced into a mold cavity where it cools and hardens to the configuration of the mold cavity. After a product is designed, usually by an industrial designer or an engineer, molds are made by a moldmaker (or toolmaker) from metal, usually either steel or aluminium, and precision-machined to form the features of the desired part.

Risks:
* More defects
* Disease prone due to plastic

Question by MUHAMMAD ALI M: how to fabricate a investment casting die?
how is the steel mold used in investment casting produced. the mold used in the process of fabricating the patterns(Wax replicas of the desired castings by injection molding.)
the steps on designing the die. have drawn the product on CATIA sofware. the problem is on the design of the core and cavity also the runner and such.

Generally, they would be machined. It would also be typical to make them of aluminum rather than steel, as the strength of steel isn’t needed and aluminum is easier to machine.
