Wallis is a leading polycarbonate sheet manufacturer and polycarbonate sheet supplier based in China.
Manufacturing companies employ various techniques in the fabrication of polycarbonate sheets.
To tailor polycarbonate sheets for specific applications, companies utilize methods such as laser cutting, printing, thermoforming, cutting, bending, bonding, sanding, and polishing.
Thermoforming
Thermoforming of polycarbonate is a highly intricate fabrication process that demands meticulous adherence to a well-defined procedure.
The process entails heating the polycarbonate sheet to a temperature below its boiling point while positioned against a mold, allowing it to conform to the mold's specifications.
Typically conducted at temperatures exceeding 150℃, the heating renders the thermoplastic sheet glassy and liquid enough to flow over the mold. Subsequently, the sheet takes on the shape of the mold, and any excess material is trimmed away after the completion of the process.
This method proves to be highly practical, emphasizing the importance of strictly adhering to the critical process modifications associated with its application.
Bending Polycarbonate sheets
Bending polycarbonate sheets is a straightforward process owing to their inherent flexibility.
Specialized bending machines are employed to exert force on the surface of the polycarbonate sheets, facilitating the bending procedure. The thickness of the sheet plays a significant role in determining the pressure applied during bending.
Various bending methods include cold curving, hotline bending, and cold line bending.
When engaging in the bending of polycarbonates, it is crucial to observe necessary precautions. Avoid using sharp tools or applying excessive force during the bending process to prevent potential damage to the sheets.

Cutting Polycarbonate sheets
The cutting of polycarbonate sheets is accomplished using tools like saws, lasers, and water jets.
This process, while relatively uncomplicated, demands precision for accurate results. Manufacturers offer the service of cutting polycarbonate sheets to specific sizes, ensuring exact specifications for business needs.
The choice of cutting technique depends on the thickness and size requirements. Commonly, saws such as table saws, band saws, and circular saws are employed for cutting polycarbonate sheets. Among these, a circular saw is often found to yield optimal results when carefully monitored during the cutting process.
In instances where intricate shapes are required, lasers become the preferred tool for achieving delicate cuts.
