Hot Plate Welding: Part Sticking & PTFE coming off
Hello guys,
I'm having problems with my hot plate welding. The wo main issues are part sticking and PTFE coming off from carrier plate made from steel. We weld HDPE 10%GF and HDPE at 240ºC and for both surfaces the PTFE is coming off.
Does it happened with someone and was able to fix the issue? If needed more informations please tell me.

Pilot,
Thank you for your tips. The quality requirements for welding are low but the weld must resist X Force and cannot let pass water (watertightness) . Waiting 2s in front must be a good idea althought the cycle time will be higher. Shouldn't the strength curve goes DOWN if the welding is weak? I mean , max strenght will be lower with poor PTFE than with good PTFE, or ma I misunderstanding something?
Can you please what brand of mirrors you're talking about?
Once again, thank you!
Paolo

I am talking about PTFE mirrors. The strength curve will go up with bad sutface and than it will drops down. It is a paradox. please test the parts on daily base and put results into graph. You can also reduce a pressure of melting parts on mirror during melting.
