Injection Moulding Design and Tooling

Injection Molding – What Does It Mean?

Injection Molding is the process by which raw materials or polymers like thermosetting plastics or thermoplastics gets converted into plastics parts. Usually, plastics manufactured in China and those mould manufacturer of China makes use of this injection molding.

Design and Tooling:

The injection molding process consists of four significant steps which are

Clamping:

Here the mould is kept securely without any disturbance using hydraulically powered clamping unit. This is securely closed to allow the process of injection properly.

Injection:

Initially, the polymers will exist in powder form, which is then transferred into the injection molding machine. Here polymers melted to get the molten state and injected into the pressure packs soon after melting.

Cooling:

After injecting into the mould, the molten material cooled for some time. Cooling is taken care much by China mould manufacturer, as this process will decide the accuracy. Sometimes shrinkage happens like a major issue during the cooling process corrected at the injection stage properly.

Ejection:

After mould parts get completely cooled, mould parts removed out of the mould using some force. A release agent sprayed into the mould to get out the plastic parts without any damage.

One of the China mould manufacturers named HQ Mould, giving more importance to all of these moulding design and the part designs as well. The part design includes the draft, wall thickness, radii and corners, ribs and bosses and the weld part lines etc. These are majorly considered by China mould manufacturer to avoid any defects in the plastic parts.
