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 belt welder used in hot plate conveyor 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...

Liaoning Unify High-Frequency Equipment Co., Ltd. is a renowned Chinese welding machine supplier, we provide rf welding supplies , hf welder for sale, welding equipment bag and etc. Want to know more? Please contact us. rf heat sealing equipment 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 sealing equipment 1. Radio frequency heat sealing equipment anti-wave interference device: high frequency stabilizer and high frequency magnetic field shielding system device, to minimize the high frequency int...

Liaoning Unify High-Frequency Equipment Co., Ltd. is a renowned Chinese leather belt embossing machine manufacturers , we provide automatic high frequency welding machine , hf welder for sale, high frequency pvc welder and etc. Want to know more? Please contact us. The leather belt embossing machine mainly uses a high-frequency, high-voltage rectification self-excited high-frequency tube to oscillate instantaneously to generate electromagnetic wave current electric field. Using the processed leather materials such as PVC, TPU, EVA, PET, etc., the internal molecules of the leather in the electromagnetic wave electric field generate polar friction heat generation. With a certain pressure, the leather that needs to be heat-sealed is welded to seal. General equipment for leather belt embossing machine: 1. Single-head push-type leather belt embossing machine It mainly uses a high-frequency, high-voltage rectification self-excited high-frequency tube to oscillate instantaneously to gener...

Liaoning Unify High-Frequency Equipment Co., Ltd. is a renowned Chinese welding machine supplier, we provide hf welding pvc welding machine, solid state hf welder , high frequency pvc welder and etc. Want to know more? Please contact us. The solid-state high-frequency welding machine is different from the electron-tube high-frequency welding machine. The electron-tube radio frequency welding equipment has output welding transformer. The induction coil is installed on the secondary side of the welding transformer, which is easy to match. Solid state HF welder in addition to the low working voltage, at the same time slot way capacitance and induction coil, wear on the welding steel pipe resonant directly, because there was no welding, less level of coupling, significantly higher efficiency, and then the production of induction coil, strict and standard, make it match, due to the voltage at the same time, the low induction coil diameter and welding steel pipe diameter (the clearance of...
