The Advantages of Plastic Injection Molding

High Production Efficiency

The process of plastic injection molding is highly automated, unlike the human, machines can work continuously without break as long as there is no failure of machines. So the production efficiency is quite high and is well-suited for mass production.

Workable for Complicated Parts

It supports to create a part with different geometric shapes from simple to complicated ones. More importantly, there is less finishing work required as the plastic injected products look like finished, what we need to do is just to make sure the feasibility of the design.

A Wide Range of Materials Available

We are allowed to choose a wide array of materials for plastic injection molding, we can even mix different materials to achieve specific properties, which is called co-injection molding.


The plastic injection molding requires few operators as most processes are automatic, thus, the labor cost is reduced. On the other hand, there is little waste during the process as the excessive materials can be recycled, which saves the material cost.

What is Plastic Injection Molding?

Plastic injection molding is a manufacturing process that can produce identical plastic components in large volumes. There are many plastic materials available for this process, and the most commonly used materials are thermoplastic and thermosetting polymers. It is very popular that is widely used in different industries, such as automobile, medical, aerospace, consumer electronics and so on.

How Does Plastic Injection Molding Work?

Plastic injection molding is not easy work, every step matters.

STEP 1: Feed Materials

At the first step, the plastic material would be fed into a heated barrel and mixed by using a helical-shaped screw.

STEP 2: Injection

The plastic material would be heated and molten into a liquid state that would be injected into the mold. At this time, the displaced air would be exhausted through the vents of the injection pins and the parting line.

STEP 3: Cooling

When the plastic material cools sufficiently, it solidifies and forms a shape that matches the shape of the mold. Cooling time is decided by the material used and the thickness of the plastic components. The mold is designed with cooling or heating lines inside, and water is circulated through the mold to maintain a constant temperature.

STEP 4: Ejection

The mold opens and ejector pins would eject the part from the mold, and the part would fall in a bin located below the mold.

STEP 5: Recycling and Packaging

In the last step, we would classify the usable parts and other materials that can be recycled to lower the cost, while the usable parts would be packed.
