Plastic welding process of conveyor belt welding machine  is achieved in there ways, softening by external heat source, softening by mechanical motion and softening by electromagnetic action. Conveyor welding  machine used in hot plate welding can be said to be the most simple plastic welding technology. It is especially suitable for welding large plastic materials which need large area of welding surface. The general conveyor belt welding machine acts on the waterproof material. The heat produced softens the product. The period is longer. The molten resin will stick to the waterproofing board and it will not be easy to clean. Impurities that affect bonding strength will be formed for a long time. Pressure and time should be strictly controlled to ensure proper melting amount. With different kinds of resin or metal and resin joint, there will be insufficient strength. But the conveyor belt welding machine produced by our company adopts the way that welding device is simple and wel

RF heat sealing equipment uses the friction heat generated on the contact surface of two workpieces to be welded to melt the plastic. Heat energy comes from a certain pressure, a workpiece on another surface with a certain displacement or amplitude reciprocating movement. Once the desired degree of embossing is achieved, the vibration will stop, but there will still be a certain amount of pressure on the two workpieces, so that the just embossed part of the cooling, curing, thus forming a close combination. Characteristics of RF heat sealing equipment 1. High frequency thermal sealing equipment anti-wave interference device: high frequency stabilizer and high frequency magnetic field shielding system device, to minimize the high frequency interference, effectively solve the impact of high frequency interference on other machines or residents. 2. RF heat sealing equipment week stability: the use of international industrial band 27.12MHZ, stable output cycle, in line with th

At present, pvc membrane welding machine  has been widely promoted in a number of plastic welding industry. Various welding defects are inevitable in the process of use. In this article, it mainly analyzes how to solve the problems in debugging or welding. 1.Crush and bruise Pressing injury and abrasion are common problems in the process of pvc membrane welding machine. Sometimes it's not so serious, and it just gets white or marks. When you encounter such problems, the first thing to do is to ensure that the location of the tooling is not out of alignment. First let off the air of the cylinder, press down the welding head, and carefully observe whether the welding head position of the scratch is correct. If the welding head is in the correct position, or if the abrasion or compression occurs on the support (or lower cover), then it is necessary to observe whether there is any interference between the tooling and the product. If it is old tooling, it is suggested to clean th
