Meera, here are the 5 straight points on How to avoid heat affects during cutting PEEK plastic with laser? Optimize Laser Parameters: Adjust laser power, pulse duration, and repetition rate to minimize heat buildup.

Use Coolant or Air Assist: Employ a coolant or air assist system to dissipate heat and prevent material overheating.

Control Cutting Speed: Maintain an optimal cutting speed to balance material removal and heat generation.

Consider Multiple Passes: Divide cutting into multiple passes to reduce heat accumulation per pass.

Ensure Proper Ventilation: Adequate ventilation helps remove smoke and fumes, preventing heat buildup and maintaining cutting quality.
