hot melt docking
21 Sep 2018
hot melt docking The hot melt butt joint is a method in which the polyethylene pipe end interface is heated and melted by a heating plate and then butted and fused to each other and cooled and fixedly connected together. A hot melt electric welder is usually used to heat the end pipe, melt it, quickly attach it, maintain a certain pressure, and cool to achieve the purpose of welding. Polyethylene pipes of various sizes can be connected by hot melt bonding. However, it is recommended to use a capacitor connection for pipes with a nominal diameter of less than 63 mm. The method is economical and reliable, and its interface has higher strength than the pipe itself during tension and pressure. Ready to work. The butt pipe sections shall be of uniform pipe type, and the same plant supporting materials shall be used as far as possible; the outer diameter and wall thickness of the butt pipe sections shall be the same; the inner and outer surfaces of the welded pipe and pipe fittings, especial...
The hot-melt welding machine
14 Sep 2018
The hot-melt welding machine adopts a plate-type structure and uses an electric heating method. The whole machine is in the form of a frame. It consists of three plates: upper template, lower template and hot template. It is equipped with hot mold, upper and lower plastic cold molds, and the action mode is pneumatic control. It is mainly used for welding of plastic parts such as household appliances, car lights and car dissolvers. According to different plastic parts, the heating power and mold size can be set to realize welding of various plastic workpieces, which is easy to operate and convenient to use. product description The device adopts a plate-type structure, and the heat of the heating plate is transferred to the welding surface of the upper and lower plastic heating members by an electric heating method. The surface is melted, and then the heating plate is quickly withdrawn. After heating the upper and lower heating members, the molten surface is fused, solidified and integra...

(3) Take out the milling cutter, close the ends of the two tubes and check the alignment of the two ends. The displacement of the two ends of the pipe should not exceed 10% of the thickness of the pipe or the larger of 1mm. The pipe straightness and the tightness can be corrected to some extent. When the pipe is closed, there is no obvious gap between the two ends of the pipe. The maximum width cannot exceed: 0.3mm (DN< 225mm), 0.5mm (225mm<DN<400mm) or 1.0mm (DN>400mm). If the above requirements are not met, they should be milled again until the above requirements are met. (4) Measure the drag force (the frictional resistance of the moving fixture), this pressure should be superimposed on the process parameter pressure to get the actual use pressure. Also check if the heater plate temperature has reached the set value. (5) After the temperature of the heating plate reaches the set value, put it into the frame and apply the specified pressure until the minimum curl on both ...
