Plastic and plastic compounds are used in many applications today because of the low cost of production, strength, ease of manufacture and high adaptability. Plastic structures are often produced with an injection molding process. Although the initial cost to create a mold and mold for injection molding is high, the cost of production for extruded plastic parts is relatively inexpensive. For this reason, most high volume products use molded plastic parts. Common plastic products include bottles, food containers, bags, clothing, pipes, computers and computer accessories. Plastic materials such as polyethylene terephthalate (PES) are used for food packaging. Polyvinyl chloride (PVC) is used for pipes, polyvinylidene chloride (PVDC) is used for containers, and polyethylene (PE and HDPE) is used for a wide variety of applications. Determining the mechanical properties of these materials is important for the quality of the product design. Compression tests of plastics are commonly performed to determine the modulus of elasticity, yield stress, deformation beyond yield strength and compressive strength. TestResources Plastic Compression Test Equipment is modular and configured by our application engineers to meet the unique application requirements of our customers. Plastic compression testing machines can be built to include many products from our product line, including; test software, grips, test accessories, extensometers, environmental chambers and sample preparation aids.
