With the rapid development and extensive use of HDPE in China, the manufacturers of hot-melt welding machines in China have emerged in a harsh situation. As a unit of use, combined with your own economic situation, how do you choose a good quality machine?
suggestions below:
The use of gas companies in the country's current PE pipe welding specifications recommended the use of fully automatic welding machines, the market has imported, there are also joint-stock products, there are several domestically produced fully automatic has been made. The price of the products varies greatly. How to choose?
1, understand the company's technical strength, product work.
2, understand the after-sales service measures, good after-sales service is an effective guarantee for your fast handling of machine failures.
3. If 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 the machine can store, 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 boost in the T4 phase is slow, the slow boost is to prevent the molten PE material from colliding under the rapid high pressure to form a virtual weld.
7. What is the pressure-retaining range of 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 to 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.
