What is Injection Moulding?

Injection moulding is the most commonly used manufacturing process for producing higher volumes of plastic parts. The injection moulding process requires using an injection moulding machine, raw plastic material, and a mould. The plastic is melted in the injection moulding machine and then injected into the mould, where it cools and solidifies into the final part.

INNORATOP can deliver parts in as little as ten days, thanks to our injection moulding technique, depending on your project requirements.

Advantages of Injection Moulding:

●Large production volume, fast speed and high efficiency

●Low-cost unit price

●Complex shapes possible (not limited to specific design)

●The product qualification rate is high, and there are few defective products

●Large selection of materials

●Good colour control

●Injection moulding is a repeatable process with good product consistency

●The injection moulded parts have a good appearance of the finished product

Injection Moulding Process:

Clamping

The process begins with clamping the mould under pressure to accommodate the injection and cooling.

Injection

The molten thermoplastic material is injected under pressure into the mould through either a screw or ramming device.

Compression

Once the molten plastic is injected into the mould, pressure is released to ensure all the mould’s cavities are filled using hydraulic or mechanical force.

Ejection

Utilizing rods, a plate or an air blast ejection is completed to remove the plastic component from the mould.

The movable platen is separated from the fixed platen to separate the mould.

Opening

The movable platen is separated from the fixed platen to separate the mould.

Cooling

The plastic is left to cool and solidify within the mould.
