CNC Machined Materials-Engineering Plastic Applications

Plastic is a common non-metallic material that has good insulating properties and cost advantages. Plastic materials are often used in the manufacturing of electronics, electrical appliances, and automotive parts. When selecting plastic materials, factors such as physical properties, mechanical properties, wear resistance, and processability must be considered.

In this article, we will select several plastic materials suitable for CNC machining for everyone to use as a reference for their choices.

No.1  PMMA(Polymethyl Methacrylate (PMMA))

Colour: Colorless

PMMA also is called Acrylic and Plexiglas, ''PMMA'' is often used as a lighter, shatter-resistant alternative to glass in everything from windows, aquariums and hockey rinks.

Performance:

The gloss performance is high and can be used for surface polishing. It has a stable shape at warm temperatures and is suitable for a range of -40 to 90 degrees. It is UV resistant and has excellent weather resistance. It has good electrical and dielectric properties, as well as excellent mechanical strength.

Applications:

Ventilator hoods and accessories, fan blades, relay covers, windshields, electrical medical equipment, transparent models, decorations, advertising nameplates, etc.

No.2 Polyether ether ketone (PEEK)

PEEKis a high-performance engineering plastic known for its excellent mechanical properties, chemical resistance, and high-temperature working capability. PEEK plastic is widely used across various industries, and its unique characteristics make it an ideal material for high-demand applications.

PEEK is known for its high thermal stability, excellent mechanical properties, chemical corrosion resistance, and wear resistance, and is widely used in industries such as aerospace, electronics, medical, automotive, and oil and gas.
