Hot Plate Welding

Hot plate welding is the process of heating two pieces of plastic and pressing them together until they fuse. There are several different types of hot plate welding. Each technology differs in how they apply heat and pressure to the parts, but the basic steps are the same — add heat, apply pressure, and cool. Plastic welds are strong molecular bonds. Depending on which welding technology is used, the weld is hermetically sealed.

高效率和低成本:有不可或缺的作用

The HUAZHUO machine portfolio for hot plate welding is comprised of various sized standard machines for welding parts of different sizes. Common applications in the automotive industry include glove boxes,center consoles and map box linings. During hot plate welding, the plastic parts are welded using radiant heat and contact with an electric hot plate. Despite involving contact, this is a particle-free process that allows very strong and completely tight welds to be created for a number of different plastics.

Even thin-walled parts with complex 3D contours can be processed reliably with this well-established, robust process. Modern tool change systems, sophisticated drive technology, and the appropriate degree of automation increase productivity and make this fully developed process attractive for a number of industries and applications.

Hot Plate Welding Process

Hot plate welding is a multi-step process, as the heating and joining of the parts occur separately. After the parts are inserted into the fixture, they are placed against an electrically-heated plate. This contact with the hot plate begins the welding process, which is divided into three phases:

Melt, Open, Seal.
