Advantages of Plastic Processing
1.Processing speed: Plastic is usually softer than metal, so CNC machines can cut
plastic materials faster and improve production efficiency.
2,Tool wear: Due to the lower hardness of plastic, there is less wear on the
tool, which means a longer tool life and reduces the frequency and
cost of tool replacement.
3.Cost effectiveness: Plastic materials themselves are usually cheaper than metals, and
the energy consumption during processing is lower, thereby reducing
overall processing costs.
4.Design flexibility: Plastic is easy to process into complex shapes and details,
providing designers with greater freedom.
5.Weight: Plastic products are much lighter than metal, which is
particularly important for applications that require weight
reduction, such as aerospace and automotive industries.
6.Corrosion resistance: Some plastics have excellent chemical corrosion resistance and are
suitable for applications in special environments.
7.Insulation performance: Plastic is a good electrical insulator, suitable for electronic
and electrical applications.
8.Shock absorption performance: Plastic has good shock absorption and sound absorption properties,
suitable for situations where noise and vibration need to be
reduced.
Plastics Frequently Used in CNC Machining
1.Polyamide (Nylon, PA):
Characteristics: Wear resistant, oil resistant, chemical resistant,
self-lubricating.
Application: Mechanical parts such as gears, bearings, sliders,
seals, etc.
2.Polyoxymethylene (POM, Saigang):
Characteristics: High rigidity, low friction, good dimensional
stability.
Applications: precision gears, bearings, fasteners, automotive
interior parts, etc.
3.Polycarbonate (PC):
Features: high transparency, impact resistance, heat resistance.
Applications: protective masks, optical components, electronic
device casings, etc.
4.Polyether ther ketone (PEEK):
Characteristics: High temperature tolerance, chemical stability,
high mechanical strength.
Applications: aerospace, medical equipment, high-performance seals,
etc.
5.Polytetrafluoroethylene (PTFE):
Features: extremely low friction coefficient, excellent chemical
stability, high temperature resistance.
Application: Seals, liners, sliding bearings, etc.
6.Acrylonitrile butadiene styrene copolymer (ABS):
Features: Good impact strength, good processing performance, and
surface electroplating capability.
Applications: Automotive interiors, consumer electronics casings,
toys, etc.
