OUR DAYTON TEAM carefully assess the best injection molding plastic materials to use in the project at hand.

One of the most important parts of the injection molding plastics process is assessing which materials are best suited for the job at hand. The material chosen will affect not only mold operation but part performance as well. 

Plastic Injection Molding Dayton utilizes plastic injection molding plastics like polypropylene (PP), polyethylene (PE), polyamide (Nylon), acrylic, polycarbonate, polyoxymethylene (POM), polystyrene (PS), acrylonitrile butadiene styrene (ABS) and thermoplastic polyurethane (TPU) and thermoplastic rubber (TPR). 

There are many plastics available and we’ll help you choose the best one for the part at hand. The material’s strength, durability and flexibility must be considered for the job the part needs to perform. Our team will also take color and cost into consideration.

dayton Best Materials For The Job

Polypropylene, or PP, is a thermoplastic material most commonly used when creating a product that contains or may be in contact with food. It is widely used in the food storage and food packaging industry. When no longer containing food, this plastic is highly tolerant of washings with hot water and sees no degradation. PP has a high chemical and moisture resistance. Count on this plastic for toughness, strength, durability and elasticity.

Polyethylene, or PE, is another thermoplastic with similar strengths to PP but is not nearly as strong or hard. Still, PE is food safe and is used in such products as milk jugs and medicine bottles. You will also find PE utilized to make clear food wrap, shopping bags and laundry detergent bottles.

Polyamide, also known as nylon, is commonly used in clothing and other textile products, the automotive industry, carpets and kitchen utensils. Nylon is known for its strength and high durability. Nylon is tough, chemical resistant and has a high melting temperature.

Acrylic is often used to create transparent parts. It’s weather and scratch resistant, strong, stiff and optically clarient. It is often found in refrigerators and containers that store food because it is free of BPA and is also odorless and tasteless.

Polycarbonate is quite similar to acrylic and is often used when something stronger than its counterpart is necessary for a product. It is also transparent and durable, but is not typically suitable for anything that will come in contact with food or other ingested products as it contains BPA.

Polyoxymethylene, or POM, is a type of acetal resin used for manufacturing parts that would usually be made with metal, like mechanical and automotive parts. POM is also found in the manufacturing of gears, fasteners, knife handles and ball bearings. It has high resistance to alcohols, gasolines, detergents and motor oils.

Polystyrene, also known as PS, is an inexpensive, non-environmentally friendly plastic. There are two types of PS plastics used in injection molding, HIPS and GPPS. You’ll find both types of PS in household appliances, electronics and more.

Acrylonitrile Butadiene Styrene, commonly referred to as ABS, has many advantages in using it for manufacturing plastic products. It’s tough with high impact, scratching, tearing and breaking resistance. It is also relatively inexpensive. You’ll often find this plastic in electronic housing, auto parts, pipe fittings and even Legos!

Thermoplastic Polyurethane (TPU) is soft and elastic and often used to produce parts with a rubber-like quality. TPU is often used in power tools, cable insulation and sporting goods.

Thermoplastic rubber, or TPR, is a mix of plastic and rubber and exhibits properties of both materials. This material is recyclable and easy to work with in the plastic injection molding process. TPR is used in both medical catheters and headphone cables.
