The hot plate welding (on the flat system), it uses electric heating metal molds The thermoplastic welding process that is softened by the surface of the plastic parts is almost applicable to all or large or small thermoplastic parts. The is particularly suitable for welding softer semi -crystalline thermoplastic plastic. Because the surface temperature of different mold surface is suitable for two different thermoplastic materials, this process is most suitable for welding different materials. This welding can achieve a high welding strength, but the cycle of this process may be relatively long, small components need 15s, and large components take a few minutes.
2, hot air welding:
This welding method is widely used to connect the welding method of hot plastic profiles and sheets. I is suitable for the repair of smaller injection molding parts, the repair of thermoplastic parts, and the manufacturing of the sample parts. It is important to use a polymer brand with the same polymer brand as the welding parts.
3, squeezing welding:
The welding method developed from hot air welding. Automatic welding. Extension information:
PVC hard board is a plate made of PVC as raw materials. PVC hard board is a widely used product in industry. Special It is used in the chemical anticorrosive industry. PVC hard board suppression process: PVC hard boards are usually made of pressure -delayed PVC sheets and heating and suppression. PVC hard board suppression is divided into 3 heating stages, 1 adjustment phase, 1 cooling stage. 1, low temperature heating phase. 2, medium temperature heating phase. 3, high temperature heating phase. 4, stop heating adjustment phase.
