How to choose the hot melt machine hot melt welding machine choice 4 steps First, 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, and then cooled and fixedly connected together. The hot melt welding machine usually uses hot melt to heat the end tube, melt it, quickly attach it, and cool it to achieve the purpose of welding. Then, how do we choose a hot-melt welder in industrial applications? What is the right thing to do? Do a simple analysis: Many of the gas companies in the country currently use the PE pipe welding specifications recommended to use fully automatic welding machines, the market has imported imported, but also joint venture assembly products, there are several domestically produced fully automatic has been made. The price of the products varies greatly. 1. Understand the company's technical strength and product workmanship. 2, understand the after-sales service measures, good after-sales service is an effective guarantee for your fast handling of machine failures. 3. Once the machine fails, the manufacturer can't repair it in a short time, what kind of emergency measures the manufacturer can have. 4. How much welding data can be stored in the machine, how to transfer the data to the computer, and then print it out. 5, the welding data can not be modified, the welding data format that can be modified provides the conditions for fraud is never allowed. 6. Whether the boosting in the T4 phase is slow, the slow boosting is to prevent the molten PE material from colliding under the rapid high pressure to form a virtual solder. 7. What is the range of pressure compensation in the pressure-holding stage? The ultra-small is better. The current welding parameters are summarized by the foreign developed countries through practical science, so the pressure value of the actual welding is as close as possible to the parameter table. 8, the hot plate automatically bounces one can reduce the time of T3, the second amount can reduce the artificial factors to bring the welding failure. Because of the fully automatic products, the programmed products generally fail, and the on-site users cannot repair them. Therefore, in order to save some money, but to buy a machine of poor quality, system instability, otherwise the loss you spend on repairs and lost work in the future is definitely greater than the difference. At present, most users still use hydraulic hot-melt welding machines. The quality of welding depends entirely on the quality of the machine and the technology of the operators. Although the hot-melt welding machine is rarely used in life, it is widely used in industry and heavy industry, so knowing or knowing some knowledge of the choice of hot-melt welding machine can well enrich the experience of working later. of. Hot melt machine purchase step 1. Determine the type of hot melt machine according to the material of the product, the method of gluing and the required requirements, and the hot melt adhesive used. Type: hot melt glue machine, PUR glue machine, dispensing machine, glue machine, glue machine, glue machine, glue machine, hot melt glue coating machine, water-based glue machine, etc. When a customer purchases a hot melt machine for the first time, it is recommended to contact the professional glue supplier and the glue machine manufacturer for better results. 2. According to the production quantity per minute of the sizing product, the amount of glue applied to each product, and finally calculate the amount of glue per hour. Select the capacity of the hot melt machine mainframe according to the amount of glue used. Usually, the number of kilograms referred to by a hot melt machine refers to the amount of glue per hour. This should be chosen according to the actual application, of course, you can choose a larger one. 3, according to the accuracy requirements of the product gluing, the convenience of the production line on the site or not choose different models The domestic hot melt glue machine standards are not uniform, and different hosts can be selected according to their own needs. 4.
