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 high frequency electric field direction, due to the molecular polarization, so as to achieve solid fusion.

Heat sealing machine principle: we talking about heat sealing in a narrow sense, namely is to use temperature condition, made by processing plastic sealing parts, heat close to the melting point of plastic material, make it into a viscous flow state, at the same time, to a certain pressure and make the two layers of plastic membrane fusion, cooling after a period of time, plastic material can maintain a certain strength and sealing performance. Guaranteed the commodity in the packing, the transportation, the storage and the consumption process may withstand certain external force, the commodity does not crack, the leakage, achieves the protection commodity the goal. The principle is simple, and the operation is simple.

Different product range:

High frequency processing products range: high frequency processing, also known as voltage processing. The main target is relatively thick plastic materials, or plastic products processing requirements precision, firmness and other processing properties of the higher case, the need for high frequency voltage processing.

Advantages and disadvantages of automatic high frequency welding machine:

High cycle processing advantages: processing process, all working parameters precise control high cycle machine, the processing of plastic parts of the product whether in sealing, firmness, appearance, or precision is absolutely perfect. The processing speed of the product is medium.

Using the high frequency principle, the operation is a little complicated, the cost of the machine is higher than that of the heat-sealing machine.

Advantages and disadvantages of hot sealing machine processing:

Advantages of hot sealing machine: low cost, simple operation, easy for employees to use, medium processing speed.

Heat sealing machine processing products: due to the principle of the heat-sealing machine, we can know, heat sealing machine is mainly suitable for the processing of thin plastic film material, product packaging requirements is not very high-end.

Because of its completely by temperature to heat plastic parts, achieve the goal of welding, the temperature is difficult to accurately grasp the optimum temperature for possible because machine time for a long time, cause temperature too high or too low adverse phenomenon, lead to welding unstable heat-sealing products, sealing, or plastic glue processing, makes the product welding deformation, rough, not beautiful. At the same time, the overall production efficiency of the machine decreases.

Plastic welding process of conveyor welding machine is achieved in there ways, softening by external heat source, softening by mechanical motion and softening by electromagnetic action.

Conveyor belt 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 welding strength is high, and the shape design of products and welding parts is relatively easy. Generally, after melting and softening the two plastic planes to be welded, remove it quickly to electric heating plate and combine the two surfaces and apply force until it is cooling down.

Another way is that when the hot air flow of the welding machine is blowing to the joint area, melt the welding wire between the joint area and the waterproof material and the weld is formed by melting the soldered plastic with the filling material. The welding machine equipment of this method is light and easy to carry but the welding skill requirement of the operator is higher. The two technologies of hot rod and pulse welding are mainly used in the welding of plastic film with small thickness. The two methods are similar. They press two thin films together and use the instantaneous heat generated by a hot rod or nickel-chromium wire to complete the welding.

The industries using high frequency plastic welding machine are as following:

Processing a thermal welding sealing such as:  blister sealing, PVC plastic blister sealing, PVC blister welding, PVC plastic bubble shell, battery sealed packing sealing, hardware tools, PETG blister sealing, blister cardboard sealing, U disk sealing packing sealing, memory chips, PVC blister welding, high frequency plastic welding, HF plastic welder, high frequency plastic sealing, double blister sealing, PVC blister sealing double-sided, double-sided board blister sealing, cardboard blister sealing, plastic heat sealing welding, and so on.
