HOT PLATE WELDING IS THE PROCESS OF JOINING TWO PARTS OF A PLASTIC COMPONENT USING HEATED PLATE.HOT PLATE WELDING, ALSO KNOWN AS MIRROR, PLATEN, OR BUTT WELDING, IS USED FOR WELDING INJECTION-MOLDED COMPONENTS, FOR EXAMPLE IN AUTOMOTIVE APPLICATIONS, AND EXTENSIVELY IN JOINING PLASTIC

BRIEF INTRODUCTION OF HOT PLATE WELDING MACHINE

The hot plate welding machine is a thermoplastic welding equipment using the surface thermal conduction method to melt thesurface of the thermoplastic workpiece being welded and can be applied for melting and connection of refractory workpieces,such as water tanks, combination auto lamps, automobile door plates, bumpers and sinks of washing machines, etc..

Plastic welding using hot plate method involves three sequential stages namely surface preparation, application of heat and pressure, cooling.The parts to be welded are pressed on preheated plate for predefined time for sufficient plastic material to melt. Then the heated plate is withdrawn and the slightly melted surface of two parts is pressed together to form a joint. Plastic welding using hot plate welding is useful where plastic parts have complex geometries, like curved surfaces and internal walls or any irregular shapes. This process is employed where both high strength joints and hermetic seals are required.

This process requires precision with regards to temperature setting and requires precise surface matching for the joint to form.Hot plate welding process is ideally suited for complex three dimensional joint surfaces.Typically hot plate plastic welding is employed where cost effective strong seals are required like fuel tanks, liquid reservoirs, tail light lenses, vent ducts, batteries etc.
