What are the Steps Involved in Plastic Casting Process?

They include the following;

1. Patternmaking

This is the first step in the process which involves designing of a physical model.

Patternmaking can use computer-assisted systems to design the dimensions and geometry of the mold.

It follows by packing of aggregated plastic material around the pattern.

2.Core Making

It is the second step in the process which involves placing of solid materials inside the mold cavity as a way of creating interior surfaces of a casting.

Most of the plastic part designs need the inclusion of cores in the casting mold.

3.Molding

This is the third step of this process which also allows you as the manufacturer to create the casting mold.

The plastic material fills the casting mold model which is subsequently allowed to harden to a point of removing it from the cavity and beginning of casting of the component.

4.Melting and Pouring

You must ensure that you melt the plastic material properly before placing it in the mold.

Once you have melted it accordingly depending on various properties of the plastic, you then pour the molten plastic in the casting mold to allow it to cool and also harden.

5. Finishing

In some instances, plastic can fill in the cracks in sprues or casting mold thus making it a necessity for you to finish the plastic following casting.

You can use different ways of finishing techniques to accomplish this.

Once you achieve proper appearance and texture, you can as well proceed to further post-treatment process like a painting of electroplating depending on various elements.
