Material Modification

In addition to general materials, we can also modify the materials according to the special needs of customers. Our professional engineers will adjust the raw material formula to meet the unique conditions of use. Please let us know your unique using condition, our material experts will offer you customize material solutions.


Additives of Material Selection

In order to improve the performance of the material, we can add additives to the material as required. The common additives and common properties are listed below. If you want to know more, please go to each process page to view the different additives applicable to each process and material.

Name Description
UV absorbers Absorb UV radiation, slowing down the degradation of the material when used outdoors.
Flame retardants Prevent ignition and inhibits the spread of fire.
Plasticizers Increase flexibility and promotes plasticity, reducing the brittleness of the material.
Colorants Used to color plastics.
Carbon fibers Increase strength, toughness, and rigidity of the material at the expense of making the material more brittle.
Glass fibers Increase strength, toughness, and rigidity of the material at the expense of making the material more brittle. It is more flexible than carbon fibers.

Selecting the Right Material for Injection Molding Parts


Injection molding is a process by which you can make components using heated plastic. This heated plastic is injected into a mold and allowed to solidify. Then, it is removed from the mold once ready. Choosing the correct type of plastic is essential in this case, as the project’s quality relies on the component’s quality. As such, the project requirements will determine which plastic you select.


Following is a guideline on how to choose the right plastic for injection molding parts.

FAQs of Material Selection

How should I choose the most suitable material for my project?

If you are not sure about the specific material, you can tell us the using condition, our engineer will recommend the most suitable material for you.

Can one set of mold produce products in different materials?

If the production process is consistent, it is possible, but the product will be deformed to different degrees due to different material characteristics

How do you charge for material modification service?

We won't charge extra fee on material modification service.
