Liaoning Yufei High Frequency Equipment Co.,ltd.

  A dvantages of H igh F requency H eating High-frequency heat sealing/ high-frequency sealing machine / high-frequency welding machine / HF plastic welding machine is the first choice of plastic heat high frequency sealing equipment. The principle is different from plastic welding machine with conduction of heat because it is the use of high-frequency electric field polar molecules to produce plastic torsion friction heat, and thus to achieve the purpose of welding. The welding temperature is uniform in the outside and the inside. It is mainly used for all kinds of plastic welding, welding, etc., which are on the basis of PVC (PVC). And it makes blister with different shapes or blisters plastic to weld automatically as well as trimming at the same time. It is suitable to use for two-sided welding of plastic uptake, bubble shell of plastic uptake and for sealing paper card. For special plastic material (PE, PS, PETG) with sealing, the PVC material with more than 30% for plastic wel...

  Liaoning Yufei High Frequency Equipment Co., Ltd. has the most professional technicians and the best high frequency embossing machine , stretch ceiling welding machine   . Below are the top 10 things that Yufei will tell you when using: 1. This unit must be equipped with a good ground terminal (connected to the correct ground wire). 2. The machine is extremely sensitive to moisture and dust and needs to be placed in a suitable working space. 3. The vacuum tube of the machine will generate high heat, so it should not be placed next to the machine that will generate high heat, nor should it be installed in the place where the solar energy is directly irradiated. For the above reasons, the heat dissipation function of the vacuum tube will be affected. 4. If the machine is shut down for more than one hour, and then turn on the machine, wait 10-15 minutes for the vacuum tube to warm up and protect the service life of the vacuum tube. 5. The upper and lower extremes of the machine...

  RF dryer  is a kind of high efficiency leather drying equipment. Working principle of RF Dryer In the high-frequency electric field, the dielectric water in the wet leather will be affected by the electric field, causing molecular disturbance and friction and heat between molecules, so that the moisture in the leather will get enough heat and vaporize, and then the steam will be taken away by the air to achieve the purpose of leather drying. Characteristics of high frequency dryer (1) The RF dryer working speed is fast because the electrical energy into heat, high frequency electric field and leather do not need any intermediary, so in the moment that leather is electrified, heat will produce, to achieve the purpose of rapid drying. (2) Uniform drying, good leather quality if the leather dry to the specific moisture content, will encounter a lot of problems, one of them is the moisture uniformity problem. In the past, most tanneries have dried the leather to a leathery state...

    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 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...

  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 the...

  What is the difference between automatic high frequency welding machine and heat-sealing machine heat sealing machine? We briefly introduce the different principles between high frequency voltage processing and hot sealing machine, the different ranges of processed products, as well as the advantages and disadvantages of high frequency processing and hot sealing machine processing, so as to help customers understand the specific differences between high frequency processing and hot sealing machine processing. Different principle: High frequency processing principle: as we have said earlier, "automatic high frequency welding machine  welding principle" the high frequency magnetic field energy emitted by high frequency tube oscillation, and the conduction effect in the processing of plastic parts, high frequency energy permeability material molecules inside, quickly make plastic molecule polarization of plastic material, material molecules arranged in the same direction with ...

  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 v-shaped opening) can be reduced, and it is one of the factors of improving the efficiency of welding. One thing is certain, the induction coil strict and the standard manufacture produces the benefit is far higher than the indu...
