PC(Polycarbonate) is a colorless and transparent engineering plastic with excellent mechanical properties and superior optical transparency.PC plastic has high strength, high impact resistance and excellent heat resistance, and is able to maintain its superior performance in extreme environments, making it an ideal material for making complex and precision parts.
Advances in machining technology have provided more possibilities for precision processing of PC plastics. Through CNC machining and other machining technologies, PC materials can be processed into a variety of complex shapes and high-precision parts to meet the needs of different industries.
Types of PC Materials
Colorless and transparent, with high impact resistance and good thermal stability, suitable for general purposes such as optical lenses, electronic component housings and protective covers.
Flame retardants have been added to improve the flame retardant properties of the material and comply with fire safety standards for use in applications requiring fire resistance properties.
The addition of UV stabilizers enhances the UV resistance of the material and prevents yellowing and deterioration when exposed to sunlight for long periods of time.
Antistatic agent is added to reduce the static buildup on the surface of the material, which is suitable for packaging and protective cover of electronic products to prevent static electricity from damaging electronic components.
The addition of antistatic agents reduces static buildup on the surface of the material and is suitable for packaging and protective covers for electronic products.
Advantages of PC
- Excellent Mechanical Properties
PC has extremely high impact strength and is able to remain intact when subjected to external impacts, and the hardness and rigidity of the PC material gives it excellent durability in mechanical applications. - Outstanding Optical Performance
PC has good transparency with light transmission rate of over 90%, close to the transparency of glass. It’s low birefringence makes it suitable for high-precision optical applications such as lenses and optical instruments. - Good Thermal Properties
PC is able to maintain its mechanical properties and stability at higher temperatures. PC excels in temperatures ranging from -40°C to 120°C, and is suitable for a wide range of environments.
PC Machining Technology
- CNC Machining
Cutting of PC with milling machines and CNC lathes, suitable for the manufacture of high-precision and complex parts, commonly used in prototyping and small batch production - Laser Cutting
Using a laser beam to cut PCs to form fine cuts and complex patterns is suitable for processing high-precision parts and decorative parts. - Injection Molding
PC pellets are heated and melted, then injected into the mold and molded after cooling. It is suitable for the production of a variety of products with complex shapes and precise dimensions, such as electronic component housings and home appliance parts.
PC Surface Finishing
- Polishing
Smooth and level PC surface by mechanical, chemical or electrochemical methods, improve surface finish and transparency, enhance aesthetics and feel. - Spraying
Paints, coatings or protective layers are sprayed on PC surfaces to add color and decoration and to improve protective properties such as scratch and UV resistance. - Electroplating
Plating a layer of metal, such as nickel, copper or chromium, on the surface of PC to enhance the surface’s abrasion resistance, corrosion resistance and decorative properties.
