Installation Procedure

1. Measure and mark cut lines accurately on the polycarbonate sheet using a fine-tip marker. 2. Utilize appropriate cutting tools (e.g., laser cutter, CNC router, or a fine-toothed saw) suitable for polycarbonate, ensuring clean edges. 3. Secure the fabricated polycarbonate component using mechanical fasteners (e.g., bolts, rivets) or industrial adhesives specifically formulated for polycarbonate, avoiding excessive clamping pressure.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using dull or incorrect cutting tools, leading to chipping or melting.Employ sharp, high-quality cutting tools designed for plastics and maintain appropriate cutting speeds to prevent heat buildup.
Over-tightening fasteners, causing stress cracks or distortion.Use washers to distribute load and tighten fasteners only until snug, allowing for thermal expansion.
