PC is classified as a ''thermoplastic'', and the name has to do with the way the plastic responds to heat. Thermoplastic materials become liquid at their melting point (155 degrees Celsius in the case of Polycarbonat). A major useful attribute about thermoplastics is that they can be heated to their melting point, cooled, and reheated again without significant degradation. Instead of burning, thermoplastics is like Polycarbonate liquefy, which allows them to be easily injection moulded and then subsequently recycled.
PC is commonly used for plastic lenses in eyewear, in medical devices, automotive components, protective gear, greenhouses, Digital Disks (CDs, DVDs, and Blu-ray), and exterior lighting fixtures.
The PC injection moulding, unlike pom injection, most often produces parts by polycarbonates and their blends. Since polycarbonate is highly viscous, it is usually processed at high temperature to reduce its viscosity. In this process, the hot polymer melt is pressed through into a mould with high pressure. The mould when cools, gives the molten polymer its desired shape and characteristics. This process is generally used to manufacture polycarbonate bottles, plates etc. Since polycarbonate is a poor-flowing plastic, wall thickness should not be too thin.
Properties of PC Injection moulding
- Mechanical performance: high strength, fatigue resistance, dimensional stability, and small creep (also rarely changes under high temperature conditions);
- Heat aging resistance: The enhanced UL temperature index reaches 120 ~ 140 ℃ (long-term outdoor aging is also very good);
- Solvent resistance: no stress cracking;
- Stability to water: easy to decompose under water at high temperature (use caution in high temperature and high humidity environment);
- Insulation performance: excellent (moisture and high temperature can also maintain stable electrical performance, is an ideal material for manufacturing electronic and electrical parts);
- Dielectric coefficient: 3.0-3.2;
- Arc resistance: 120s;
- Form ability: injection moulding or extrusion of ordinary equipment.
Can Polycarbonate Be Injection moulded

What Is The Difference Between CNC And Injection mould Polycarbonate?
The main difference between CNC (Computer Numerical Control) machining and injection moulding for polycarbonate lies in the manufacturing process and the level of complexity they can achieve. In CNC machining, a solid block of polycarbonate is cut and shaped using computer-controlled tools to create the desired part. It is a subtractive process that is suitable for low-volume production and complex, custom designs. On the other hand, injection moulding involves melting the polycarbonate resin and injecting it into a mould cavity under high pressure. It is a highly efficient process for high-volume production, offering precise replication of intricate designs and faster production cycles.
