What Are the Various Plastics That Can Be CNC Machined?
The specific type of plastic that is most suited for a certain application will depend on the required properties of the part, such as strength, durability, heat resistance, and chemical resistance. There are many different types of plastics, and they can all be CNC-machined. The most frequent are:
l Acrylonitrile butadiene styrene (ABS) is a strong and versatile plastic that is relatively inexpensive. It is often used for prototyping and low-volume production.
l G-10 is a glass-reinforced plastic that is strong and resistant to heat and chemicals. It is often used in electrical and electronic applications.
l Polycarbonate (PC), a robust and transparent material, is frequently utilized in optical applications. Additionally, it is chemical and heat resistant.
l Delrin (PEI). Delrin is a strong and dimensionally stable resin that is frequently used for gears and bearings. Additionally, it resists deterioration and wear.
l Polyamide (PA) or nylon. PA is a strong and tough plastic that is often used for gears and bearings. It is also resistant to wear and tear.
l Ultem (PEI). Ultem is a high-performance plastic that is resistant to heat, chemicals, and wear. It is often used in aerospace and medical applications.
l Polyetheretherketone (PEEK) is a high-performance material that is heat, chemical, and wear resistant. Medical and aerospace applications both frequently employ it.
l Polytetrafluoroethylene (PTFE) or Teflon. PTFE is a non-stick plastic that is often used for seals and gaskets. It is also resistant to heat and chemicals.
l Polyethylene (PE) is a multipurpose plastic that is frequently utilized in bottles and food packaging. Additionally, it is chemical and water resistant.
l Acetal (POM) is a robust and dimensionally stable plastic that is frequently used for gears and bearings. Additionally, it resists deterioration and wear.
l Polypropylene (PP) is a lightweight and flexible plastic that is often used for packaging. It is also resistant to chemicals.
It's crucial to take into account the part's requirements, the cost of the plastic, and its accessibility when selecting a plastic for CNC machining. The capabilities of the CNC machine that will be utilized to fabricate the part should also be taken into account. If you want more information about CNC machining plastic parts, please click here.
