Installation Procedure

1. Measure and mark precise cut lines on the polycarbonate sheet using a non-permanent marker. 2. Employ a high-speed saw with a fine-tooth blade, ensuring proper support to prevent vibration and chipping. For intricate cuts, consider CNC routing. 3. Smooth edges with fine-grit sandpaper or a deburring tool, followed by cleaning with a soft cloth and a mild, non-abrasive cleaner.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using standard saw blades not designed for plastic can lead to chipping and rough edges.Utilize specialized plastic-cutting blades with a high tooth count and appropriate rake angle for a clean, precise cut.
Applying excessive heat during machining or forming, causing melting or distortion.Maintain appropriate tool speeds and feed rates, and use coolant if necessary to manage heat buildup during fabrication.

Common Applications

  • Machine Guards and Safety Shields
