At D&M Plastics, we specialize in performing high-volume injection molding using state-of-the-art equipment and technology to create tight-tolerance precision parts down to 0.001 inches. Our capabilities include:
We also offer many value-added and secondary services, full service support, and real-time production analysis.
Depending on the end-product’s desired properties, there are a multitude of plastic injection molding material options.
This material offers very predictable shrinkage, making it ideal for projects which require particularly tight tolerances. Polycarbonate is naturally transparent, strong, and durable, and is a popular choice for protective gear, eyewear, and window parts; however, it is not safe for food applications.
Nylon’s strength makes it an ideal material for mechanical parts, sports equipment, and medical products. It is highly resistant to wear and chemicals, has a high melting temperature, and is durable against impacts.
Acrylic is transparent, and manufacturers often use it in place of glass as it is scratch resistant and has high tensile strength. This material is tasteless, odorless, and free of BPA, making it ideal for food applications.
This acetal resin commonly replaces metal in automotive or mechanical parts, such as gears or ball bearings. It has high levels of strength and rigidity, and is resistant to alcohols, motor oils, and many other solvents. However, POM cannot withstand nitric acid or hydrochloric acid.
Polystyrene is budget friendly and available in two types: High Impact Polystyrene (HIPS), which is opaque, and General Purpose Polystyrene (GPPS), which is transparent. Polystyrene is popular for single-use items such as petri dishes and food packaging, but it is not environmentally friendly and does not offer significant strength or heat resistance.
Acrylonitrile Butadiene Styrene (ABS)
ABS is a flexible and affordable engineering grade plastic with high amounts of strength and toughness. It is resistant to scratches, offers good impact resistance, and is lightweight. Common uses include electronic casings, phone adapters, and wall socket plastic guards.
Popular for food packaging, PP is highly resistant to moisture and chemicals. This thermoplastic has a high melting point and is durable, with good impact resistance and flexibility. In addition to its use in the food industry, PP can be found in automotive components, athletic apparel, and many household objects.
Polyethylene is available in two types: High-Density Polyethylene (HDPE) and Low-Density Polyethylene (LDPE). It is affordable, lightweight, flexible, and moisture-resistant, making it one of the most popular plastic injection molding materials. PE can be found in a wide array of products, including prescription bottles, plastic bags, trash cans, and geomembranes.
Thermoplastic Polyurethane (TPU)
TPU provides high levels of tensile and tear strength, withstands high temperatures, and replicates the elasticity of rubber. Manufacturers commonly utilize this material in cable insulation and power tools.
Thermoplastic Rubber (TPR)
TPR combines plastic and rubber, resulting in a material that can withstand harsh environments and chemicals. It is highly impact resistant and is commonly used in catheters and headphone cables.
