　　Introduce to you the heating principle of the leather sofa cover embossing machine

　　The embossing principle of the thermoelectric leather sofa cover embossing machine is to simply use electric (ultrasonic) heating method to transfer the heat from the heating plate to the welding surface of the upper and lower plastic heating materials. Melt the surface, then quickly leave the heating plate, heat the upper and lower heating components, and then melt the melted surface to make it hard and become a whole. The leather sofa cover embossing machine adopts a full board structure, and the whole machine adopts a frame form, consisting of three major boards: upper, lower, and hot frame. It has a hot type, upper and lower plastic cold type, and the action is oil/pneumatic. Set up two temperature controllers to adjust the temperature of the upper and lower molds separately. When welding, it can be set within the range of 0 to 400 according to the actual needs during welding. According to the size of plastic parts, heating power and mold size can be set for welding various plastic parts.

　　The heating upstream and downstream templates of the leather sofa cover embossing machine are heated through multiple heating pipes (see figure). The advantage of this heating method is that it is easy to process and assemble. But the disadvantage is that the heating temperature is low (only 400 degrees can be added), and the power consumption is high (heating 800W each, at least 10 or more heating pipes per machine). Unable to remove the heating pipe. Understanding the shortcomings of these designs can improve this. The direction of improvement is not to change the design and processing of the heating template. Because the core of the hot template is the heating source! There are so many disadvantages of ordinary heating pipelines, what is the heating method that can replace it? The answer is heat-resistant glass. Heat resistant glass can be heated and then heat can be transferred from the heat conduction template. What are the advantages of heat-resistant glass? I will explain in detail below. Heat resistant glass (a special glass containing strong heat-resistant boric acid and silicic acid components, used to resist changes in temperature difference during cold and hot fusion. Its coefficient of thermal expansion (the ratio of glass body expansion caused by temperature rise) is relatively small, and it is not easily broken by rapid temperature changes. It has various excellent properties such as low expansion, heat resistance, high temperature, corrosion resistance, and high strength. Therefore, the price of heat-resistant glass is higher than that of ordinary glass and tempered glass. The heat-resistant glass material has a high safety factor and will not cause self destruction phenomena such as tempered glass. The coefficient of thermal expansion is small, with a temperature range of 120 degrees Celsius and a heat-resistant temperature of up to 1200 degrees Celsius. Heat resistant glass is commonly used in bowls, baby bottles, laboratory beakers, industrial boiler protective glasses, mechanical equipment window glass, etc. We can use low expansion, heat shock resistance, and high temperature.
