The global plastic injection molding market is expected to reach 360.6 billion USD in 2019 and 498.98 billion USD by 2027, according to recent estimates.

This proves that the injection molding industry is a behemoth in its field.


Because there are so many technologies available to help manufacturers build their products, plastic injection molding has been a huge success.


The injection molding industry has numerous tools under its belt, ranging from pressurization to achieve uniform wall thickness to smart polymers that form new materials for injection molding.

Here are a few of the most commonly used injection molding techniques.



Materials Made to Order

When it comes to injection molding technology, some manufacturers may only think in terms of processes, but this does not have to be the case.

New polymers are constantly being developed to improve the properties of plastic materials, and selecting the right resin is just as important in product design as the manufacturing process itself.


The properties your part must have play a big role in choosing the right injection molding material. Here are a few examples:

Temperature in use

Corrosion protection

the hues

Resistivity to heat and electricity

The appearance of the surface

Strength in tensile compression

Density is a measure of how dense something is.

a lot more


In some cases, a basic plastic material will provide all of the material properties that your part requires, while in others, a more advanced material is required.

Foam Molding for Structural Applications

For minimal weight, many plastic products must have a high strength but low density.

Structural foam molding can be a useful process to use when this is required.

In structural foam molding, an inert gas is injected into the mold while the molten resin is injected at a lower pressure than usual.

The additional gas reduces density while allowing for a lower injection pressure, allowing the equipment to run more efficiently.

As a result, tooling is simpler, and equipment strain is reduced, allowing for the production of more parts.


Structural foam molding may be the way to go if a high strength-to-weight ratio is required for a large number of parts with minimal equipment strain.
