Points using hot plate welding of plastics

Date:2014-10-26 00:00 Source: Click:

Plastic hot plate welding method is by an electric heating hot plate heat transfer to the weld surface of the upper and lower plastic heating element. So that surface melting, and then exit the heating plate quickly after the upper and lower pieces of heated molten surface fusion, curing, into one. The whole framework of the form, from the template, the next template, template three large hot plates, and features a hot mold, the upper and lower plastic cold model, action for pneumatic control. Simple, easy to use. Heating plate composed by two up and down, it is heated by electric tube.

Hot plate plastic welding equipment control can be divided into two kinds of manual and automatic control, manual for single action, commissioning, mainly for institutional and manually adjusted the mold after production to adjust to automatic. Automatic control system uses a programmable controller (PLC) and touch-screen interface to control the movement of the air pressure in each cylinder, driven by easy operation, reliable performance, compact size, improve production efficiency and quality.

Ready to control the temperature changes, supported by a sound mechanism to achieve the perfect welding, ultrasonic welding machine to compensate for the lack of large and special plastic welding workpieces mainly applied to PP, PE and other thermoplastic materials and weld area the size of a large and complex plastic parts welding. For example: car tank, fuel tank, canister, brake fluid tank, bumpers, instrument panels, exhaust net, batteries, plastic pick motorcycle bitumen, washers plastic ring balance, construction of plastic doors and windows plastic workpiece.

Weld surface of the plastic pieces of metal hot plate heated by direct, hot plate welding plastic welding, heating plate placed between two pieces of plastic, when the workpiece to live close to the heating plate, the plastic begins to melt. After heating at a pre-set time has elapsed, the plastic surface melting will reach a certain degree, this time on both sides of the workpiece to separate the heating plate is removed, the next two parts blend together, when it reaches a certain welding time and after welding depth, the welding process is completed.

Users can process characteristics according to different requirements of various types of plastic parts, production efficiency, degree of automation, the choice of a machine multimode hot plate plastic welding process, in a welding process, to be completed at the same time a few pieces of plastic welding, also higher degree of automation can be used more than the table hot plate welding machine, multi-position welding. We can use a dedicated multi-weld surface long hot plate welding machines, welding achieve a complete all process requirements.
