Plastic Machining Capabilities
![custom-CNC-plastic-machining](https://proleantech.com/wp-content/uploads/2024/07/custom-CNC-plastic-machining.jpg)
- Advantages of CNC Plastic Machining
Plastics are lightweight, corrosion-resistant, and often more cost-effective than metals. They offer good electrical insulation and can be colored easily. The softness of plastic reduces the machining cycle time and the tool wear. Meanwhile, machining stability allows for complex and intricate details via milling, turning, drilling, tapping, grooving, and other suitable operations.
- What we do to make Plastic Machining Perfect
Our machining factory has 3, 4, and 5-axis CNC lathes and a machining center that can process various thermoplastics and thermosets with a precision of ±0.005mm. We handle ABS, PC, PE, PMMA, and other plastics based on your requirements. Furthermore, we also have post-processing and finishing facilities to enhance the surface quality according to your application needs.
You can trust our experience in handling any machined plastic components!

CNC Plastic Material Grades
ABS (Acrylonitrile Butadiene Styrene)
Acrylonitrile Butadiene Styrene (ABS): It is a tough and highly impact-resistant thermoplastic with excellent machinability. The ABS machining is suitable for functional prototypes, automotive parts, and consumer products.
Acrylic (Polymethyl Methacrylate, PMMA)
Acrylic (Polymethyl Methacrylate, PMMA): PMMA is a transparent material that is popular as a replacement for glass, rigid, good weather resistance, etc. Some acrylic machining parts are light fixtures, display boards, and transparent optical prototypes.
Nylon 66 (Polyamide)
Nylon 66 (Polyamide): Nylon offers high strength, wear resistance, and good chemical resistance and is suitable for gears, bushings, and bearings.
Polycarbonate (PC)
Polycarbonate (PC): PCs are high-strength transparent thermoplastic with excellent impact resistance. The preferred applications include electronic housing, safety glasses, and automotive components.
Polyethylene (PE)
Polyethylene (PE): High strength-to-weight plastic with good impact, weather, and chemical resistance. The machining PE produces containers, fittings, seals, and gaskets.
Polypropylene (PP)
Polypropylene (PP): It is a low-friction and cheap plastic with good chemical resistance, fatigue resistance, and high flexural strength. CNC-machined PP parts are suitable for machine parts, rigid packaging, and medical devices.
Polyoxymethylene (POM or Delrin)
Polyoxymethylene(POM or Delrin): High stiffness, heat and weather resistance, impact strength, and attractive appeal are the fundamental Delrin properties. It can be machined for seat belt parts, water meters, gears, bearings, etc.
Polyvinyl Chloride(PVC)
Polyvinyl Chloride(PVC): PVC is a flame-resistant plastic with high strength, electrical insulation, chemical inertness, and moisture resistance. Meanwhile, its uses are insulators, fittings elements, automotive interiors, window frames, etc.
Polyether Ether Ketone(PEEK)
Polyether Ether Ketone(PEEK): The color variation ranges from amber to transparent; other properties like excellent adhesion and chemical and thermal resistance are also helpful for parts and products, such as 3D printer beds, aerospace parts, and medical implants.
Polyethylene Terephthalate(PET)
Polyethylene Terephthalate(PET): High strength, food grade, good chemical resistance, dimensional stability, and low cost. Suitable applications include food and beverage containers, mechanical parts, and electrical insulation.
Plastic Machining Finishes
The custom CNC Plastic machining parts can be finished using different techniques to achieve specific surface properties and appearance. At ProleanTech, we have various surface finishing options, tailored to your needs.
![CNC-Plastic-machined-parts](https://proleantech.com/wp-content/uploads/2024/07/CNC-Plastic-machined-parts.webp)
As Machined:
The as-machined finish retains the machining marks, but it can be enough where the aesthetic is not required or finish quality does affect the functionality and performance. It is quick and cost-effective.
Bead Blast:
Glass or other less aggressive beads are suitable for plastic machining parts. It removes the imperfections and makes a uniform surface texture by removing a thin material layer.
Painting:
The good adhesive nature of plastic easily accepts the layer of paint to the surface of the plastic part, either for aesthetic reasons or to add protective coatings—glossy and protection against UV light, chemicals, and wear.
Brushing:
The abrasive brush rotates and removes the imperfection and burrs to create a uniform texture, providing a satin-like appearance.
