Plasticis a material made from various synthetic and semi-synthetic organic compounds.
Most plastics are on par with metals in their cost per weight, yet are substantially less expensive by volume. If suitable for your design, substitute plastic for metal to save on manufacturing costs.
Popular plastics include acetal, nylon, ABS, PVC, polycarbonate, and polypropylene.
To learn more, see our properties of plastic page.
ABS is a popular plastic used in many products and has high strength and toughness. ABS is impact resistant (including at low temperature) and has high heat resistance.
This plastic has high abrasion and chemical resistance, is more flexible than glass, and can transmit or filter ultraviolet light. Acrylic parts are used in both functional and decorative applications.
Acetal, also known as Delrin, is a thermoplastic first made by DuPont around 1952. Acetal has a high strength to weight ratio, is easily machined, and has good dimensional stability.
PTFE parts are affordable, easy to machine, and durable. Due to its low coefficient of friction and wear resistance, parts made from PTFE are often used in mechanisms that rotate or slide.
Polycarbonate is an amorphous thermoplastic first made at Bayer and General Electric in 1957. This plastic has high impact and heat resistance and is often used as electrical insulation.
Nylon is one of the most common plastics used in commercial applications, first produced at DuPont. Popular products made from nylon include parachutes, rope, guitar strings, sneakers, pipes, hygiene products and more.
Polyvinyl chloride, also known as “PVC”, is a plastic commonly used in construction applications including window profiles, piping, plumbing, flooring, wire insulation and more. This plastic has high strength, impact resistance and toughness.
Polyethelyne is the most popular plastic in the world and is primarily used to make plastic bags and films, containers, bottles, and other commercial products.
Polypropylene is a thermoplastic favored for its high melting point and impressive resistance to water, electricity, and acid. This plastic is often used in prosthetic devices, plating barrels, railroad crossing mechanisms, housewares and more.
Mills use rotating tools to cut material into almost any 3D shape. CNC Mills can work with tight tolerances.
Waterjets mainly cut sheet material into 2D parts using a high-pressure stream of water and abrasive. Waterjet cutting is suitable for most materials and yields clean edges.
3D Printing (aka Rapid Prototyping) is an additive manufacturing process. It’s often used for testing designs and quick-turn low-volume 3D parts.
CNC Lathes feed cutting tools into rotating material. Turning is mainly used to produce precise, cylindrical parts.
Injection Molding produces parts by forcing molten polymer material into a mold. It’s the most economical process for producing high volumes of plastic parts.
After manufacturing, parts may require additional processing. Secondary services include CNC bending, grinding, tapping, knurling and more.
