　　High frequency embossing machine, decoration leather embossing machine can be divided into heat sealing embossing machine according to the heating method. There are three main categories of ordinary embossing machines, which can be further divided into many subcategories based on the usage of battle materials. Such as high-frequency decoration embossing machine, high-frequency leather embossing machine, concave convex embossing machine, knitted fabric embossing machine, ordinary lace machine. According to the differences in the products produced by the leather embossing machine, there are garment embossing machines, car seat cushion embossing machines, door cushion embossing machines, cutting embossing machines, shoe leather embossing machines, luggage embossing machines, leather clothing label embossing machines, trademark embossing machines, ordinary mask machines, and ordinary insole machines.

　　Today, we will mainly explore the innovation of heating methods for heat sealing embossing machines. The embossing principle of heat sealing clothing leather embossing machines, in short, uses an electric (ordinary) heating body pattern to transfer heat from the heating plate to the fusion surface of the concave convex plastic heating element. Melt its surface, then quickly exit the heating plate, and after heating the concave and convex heating elements, the molten surface melts, solidifies, and merges into one. The decoration leather embossing machine adopts a suction plate structure, and the whole machine is in the form of a frame, consisting of three large plates: upper template, lower template, and hot template, and is equipped with a hot mold and a concave convex plastic cold mold. The action mode is oil/pneumatic control. Set up two temperature controllers to control the temperature of the concave and convex molds separately. During welding, it is possible to set the temperature within the range of 0400 ℃ according to the actual welding requirements. Ordinary embossing machine manufacturers can set heating power and mold size according to the size of non plastic parts to achieve various plastic workpiece welding.

　　The concave convex hot template of the hot press embossing machine is heated by several heating tubes, and this heating method is simple to process. However, its drawbacks are self-evident, such as low heating temperature (can only be increased to 400 degrees), high power consumption (at least 10 heating tubes are needed for a machine with a heating tube of 800W), slow heating speed, uneven heating, and difficult maintenance (the root line of the heating tube is prone to breakage, and if it breaks, it can only replace the heating plate because of thermal expansion and contraction. The heating tube cannot be pulled out). Solving this misconception may lead to improvements in this area, The direction of improvement is not to change the imagination and processing of the heating template, because the core of the heating template is the heating source! Since there are so many drawbacks to the difficult heating tube, what heating method can possibly replace it? The answer is - heat-resistant glass, which can be heated and then transferred to a thermal conductive template.

　　So, what are the advantages of heat-resistant glass? Let me elaborate on them above. Heat resistant glass (referring to special glass containing boronic acid and silicic acid components with strong heat resistance, which can withstand the temperature difference changes of cold and hot fusion. The coefficient of thermal expansion (the ratio of glass body expansion caused by temperature advancement) is small, and it is not easy to break even under rapid temperature changes. It has a series of exquisite functions such as low expansion, thermal shock resistance, high temperature resistance, corrosion resistance, and strength. Therefore, the selling price of heat-resistant glass is higher than that of ordinary glass and tempered glass. The heat-resistant glass material has a high operating safety factor and will not experience self explosion phenomena similar to tempered glass; The thermal shrinkage coefficient is small, and it can withstand a large range of rapid temperature changes (≥ 120 ℃) and high temperatures up to 1200 ℃. Heat resistant glass is commonly used in vessels, baby bottles, beakers for practical use, industrial boiler mirrors, and mechanical equipment window glass. Regarding me dressing up with a leather embossing machine. What can be utilized are low expansion, thermal shock resistance, and resistance to ultra-low temperatures.
