Welding of different plastics
2 January, 2007 - 05:47 — alban
Can somebody help me on these issues,
1)If we weld two flat plastic components-Cycoloy(PC+ABS) and PC-on which component should have energy director?
At present the PC component is provided with energy director of 0.7 mm height.But after welding,
1) The welding joint is not strong enough.
2) Energy directors are not fully melting.It leaves impression on the cycoloy component.Is it because of difference in melting temperature?
Which type of welding is suggested?Pressure or delay?
What can be the welding time?
I am using 20 kHz,2000W Sonic & Material machine..
Please help
Regards,
Alban
