Plastic CNC Machining
CNC machining services for plastic materials are available, including turning and milling simple to complex 3D parts. We work with a variety of plastic materials including Acetal (Delrin), Acrylic, polycarbonate, PVC, UHMW, HDPE, Teflon, Virgin Teflon, and brand names such as Delrin and Nylatron.
Plastic products are made up of a variety of different plastics. Plastics are polymers that are composed of long chains of molecules called monomers. There are many different types of plastics, each with their own properties and applications.
Acetal plastics are generally used for applications where high strength, stiffness, and toughness are required. Acetal is also used in the manufacture of precision parts requiring high dimensional stability.
The most common type of acetal is called POM – polyoxymethylene. It is a thermoplastic that has been around since the 1950s. POM has good mechanical properties and is easily machinable. It can be molded into complex shapes with excellent surface finish and color retention.
Acetal is a thermoplastic that is used in a wide array of applications, from automotive components to kitchenware. Acetal plastics are known for their durability and weather resistance, which make them an excellent choice for outdoor applications.
Some of the advantages of acetal plastics include:
– Low moisture absorption rates
– Excellent resistance to corrosion
– Resistance to most chemicals
– Good wear and abrasion resistance.
High Density Plastic (HDPE)
A high-density polyethylene (HDPE) is a type of plastic that is made with a chemical process called polymerization. The HDPE is then heated and cooled to make it hard.
High-density polyethylene is the most common type of plastic used in consumer packaging. It is popular because it’s inexpensive and durable, but also because it has excellent barrier properties for food packaging. Most packaging is made from high-density polyethylene.
Because HDPE bags and containers are non-biodegradable and take centuries to decompose, recycling and reusing them is imperative. Recycling HDPE has many advantages. HDPE that has been recycled is less expensive to manufacture than HDPE that has been virgin.
Inspection of a polypropylene bag from a juice company found that the bag showed no evidence of leakage on the outside, nor significant changes in weight inside or out. A polypropylene lunch bag showed no evidence of degradation after being subject to oven temperatures and gas cooking for three minutes. The durability and transparency makes it ideal for use as a food storage bag, especially for food with a low water activity level. Polypropylene is commonly used in the packaging of many liquids and semi-liquid items. It is used in most beverage bottles and some commercial fountain drink dispensers as well as in yogurt cups.
