Consider these factors for choosing right material for Injection Molding Process


When it is about making the high-quality right plastic product, one needs to ensure that they use the right injection molding process and choose the right material for the injection molding. Many industries tend to choose the custom injection molding process, especially when they have to deliver a wide range of plastic products. The Custom Plastic Injection Molding supplies the plastic products which are made using different types of plastics and other components.

 Some of the top materials used for manufacturing the plastic products are Polycarbonate (PC), Polyamide (Nylon), Polypropylene (PP), High Density Polyethylene (HDPE), and a few others. There are thousands of materials to choose from, but when you know the best materials, it becomes easy to choose. You can even have access to information from and thereby take a learned decision. One needs to consider these few things which we have mentioned below while choosing the plastic injection molding material.

 Flexibility of the material

One needs to understand and see how flexible the material is. But note one thing that flexibility of the material is not dependent completely on the softness of the material. If you know which product you have to manufacture, and how much flexibility is required, you can choose the material according to it. Like if you want a flexible ruler, choosing Nylon is wrong, as it will break or rupture easily when the load will be applied to the ruler. But if you choose the ruler made of ABS (Acrylonitrile Butadiene Styrene) material, then it will bend up to a certain extent and is flexible in comparison with the Nylon. So, depending on how much flexibility is required, choose the material.

Weight of the material

The weight of the material also matters in manufacturing the plastic products. If the client requires a low weight plastic product, one will have to choose it according to it. The density of the plastic polymer will help in knowing the weight of the product. If you know the plastic polymer’s density, you can tell, that the final product will be of heavy weight or will be of the light weight.

 Hardness of the material

There is a complete method for measuring the hardness of the material. The hardness of the material is termed as Shore Hardness. Shore Hardness is named after the inventor of the durometer, Albert Shore. Durometer is the scale which one uses for measuring the hardness of the material. One uses this device to measure the hardness when choosing the material. The softness and hardness of material are classified into type A and type D respectively. For both type A and type D, there is a variation on the scale from zero to hundred. One need to also know the usage of these materials, the environment where they will be used while checking the hardness of the material.

 Cost of the Material

When you use the China Plastic Injection Molding Process, you need to know the cost of the material. China is known for manufacturing high-quality plastic products. That is why using cheaper material will not be the right thing to do. One should check the above-mentioned things and the application of the plastic product first, and then should check the price.
