The particular kind of plastic that is most appropriate for a certain application will rely on the part's necessary characteristics, such as strength, durability, heat resistance, and chemical resistance. Plastics come in a wide variety of sorts, all of which can be CNC-machined. Among the most typical are:

Acrylonitrile butadiene styrene (ABS) is a reasonably priced, tough, and adaptable plastic. It is frequently employed in low-volume production and prototyping.
Polycarbonate (PC), a robust and transparent material, is frequently utilized in optical applications. Additionally, it is chemical and heat-resistant.
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.
Polyetheretherketone (PEEK) is a high-performance material that is heat, chemical, and wear-resistant. Medical and aerospace applications both frequently employ it.
Polytetrafluoroethylene (PTFE) or Teflon. PTFE is a non-stick material that is frequently utilized for gaskets and seals. Heat and chemicals won't harm it either.
Acetal (POM) is a robust and dimensionally stable plastic that is frequently used for gears and bearings. Additionally, it resists deterioration and wear.
Polypropylene (PP) is a strong, lightweight material that is frequently used in packaging. Chemicals do not harm it either.
Polyethylene (PE) is a multipurpose plastic that is frequently utilized in bottles and food packaging. Additionally, it is chemical and water-resistant.
Ultem (PEI). Ultem is a high-performance plastic that resists heat, chemicals, and wear. It is frequently utilized in aerospace and medicinal applications.
Delrin (PEI). Delrin is a strong and dimensionally stable resin that is frequently used for gears and bearings. Additionally, it resists deterioration and wear.
G-10 is a robust, heat- and chemical-resistant polyethylene with glass reinforcement. Applications involving electricity and electronics frequently use it.

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:
