PC sheets, or polycarbonate sheets, are typically manufactured through an extrusion process. Here's a general overview of how PC sheets are made:
Raw Material Selection: Polycarbonate resin is the primary raw material used in making PC sheets. The quality of the raw material affects the final properties of the sheet.
Extrusion:
Shaping:
Cutting and Finishing:
Quality Control: Throughout the manufacturing process, quality control measures are implemented to ensure the sheet meets specifications for thickness, clarity, strength, and other mechanical properties.
Optional Treatments: PC sheets can undergo additional processes such as surface coating for UV protection, anti-scratch coatings, or color tinting based on the specific requirements.
Overall, the extrusion process is key to producing PC sheets in various thicknesses, sizes, and finishes for a wide range of applications such as glazing, signage, roofing, and more.
