Plastic Materials for Injection Molding
At J-CAD Inc. we use the following materials for plastic injection molding;
In choosing a material it is necessary to anticipate the product’s environmental conditions.
Will it be outside in the sun all day? Will it be under water most of the time?
There are many factors when it comes to choosing the correct material for your product. J – CAD Inc. will help you with selecting the correct material through our expertise in the materials available for manufacturing your products.
SAN (Styrene Acrylonitrile) – comes in clear and colored but will be transparent. Cannot be finished as a solid color. The material is very brittle and typically used in kitchen appliances as it is food grade safe. Its cost is very low. (About Styrene Acrylonitrile)
PS (Polystyrene) – very similar to SAN (Styrene Acrylonitrile). Very low cost. (About Polystyrene)
ABS (Acrylonitrile Butadiene Styrene) – very popular material found in many household items and products. It is not flexible. It can come in any color or be translucent. It can be metal plated for visual effect. Its cost is average. (About ABS)
PC (Poly-carbonate) – very strong and comes in any color with a solid or transparent finish. Higher cost, about double the price of ABS. (About Poly-carbonate)
TPE (Thermo-Plastic Elastomers) – can come in any color. This is a very flexible, rubber material. Usually used as grip on a hard plastic handle. Similar in price to PC (Polycarbonate). (About Thermo-Plastic Elastomers)
TPR (Thermo-Plastic Rubber) – can come in any color. It is a very flexible, rubber material. Usually used as gripping material on a hard plastic handle. Similar in price to PC (Polycarbonate) but less expensive than TPE. (About Thermo-Plastic Rubber).
TPU (Thermo-Plastic Urethane) – can come in any color. It is a very flexible, rubber material. Also usually used for gripping applications on a hard plastic handle. Similar in price to PC (polycarbonate) but less expensive than TPE. (About Thermo-Plastic Urethane).
PA6 or PA66 (Nylon 6) – is a nylon material mixed with fiberglass which makes it very strong. It comes in any color. It can be mixed with fiberglass at a mixture of 5-50% glass. The final product gets stronger with more glass but also gets more brittle. (About Nylon 6)
PP (Polypropylene) – can be finished in any color or can be translucent. Cannot be fully clear. It is more flexible than ABS and less costly. (About Polypropylene)
PE (Polyethylene) – very similar to Polypropylene. (About Polyethylene)
POM (Polyoxymethylene) – very wear resistant and strong. Used for plastic gears and other parts in friction as it has good friction resistance. Higher cost. (About Polyoxymethylene)
PEI (Polyetherimide) – used for aerospace parts and high precision and strength. It is very expensive and can withstand high temperatures up to 180° C / 350° F. (About Polyetherimide)
