With the rapid development and widespread use of HDPE in China, domestic manufacturers of hot-melt welding machines have seen a severe situation of supply and demand. As a user unit, how do you choose a good-quality machine based on your own economic situation?
suggestions below:
The gas company's user country currently recommends the use of fully automatic welding machines in the PE pipe welding specifications. There are original imported products on the market, as well as joint venture assembly products, and several domestic fully automatic welding machines have already been made. The prices of products vary greatly. How to choose?
1. Understand the company's technical strength and product workmanship.
2. Understand the after-sales service measures. A good after-sales service is an effective guarantee for you to quickly deal with machine failures.
3. Once the machine breaks down and the manufacturer cannot repair it in a short time, what emergency measures can the manufacturer take?
4. How much welding data can the machine store, how to transfer the data to the computer, and then print it out.
5. If the welding data cannot be modified, the modified welding data format provides conditions for fraud and is never allowed.
6. Whether the boost in T4 stage is slow, the slow boost is to prevent the melted PE material from being knocked apart under rapid high pressure and forming a virtual weld.
7. How large is the pressure compensation range in the pressure holding stage, the smaller the better, the current welding parameters are summarized by foreign developed countries through practical science, so the actual welding pressure value is as close to the parameter table as possible.
8. The hot plate automatically pops up. First, it can reduce the time of T3, and the second can reduce the welding failure caused by human factors.
Because of fully automatic products, programmed products generally fail and cannot be repaired by on-site users. So you can't buy a machine with poor quality and unstable system in order to save some money, otherwise the loss you spend on repairs and missed work will be greater than the price difference in the future. At present, most users are still using hydraulic hot-melt welding machines, and the quality of welding depends entirely on the quality of the machines and the skills of the operators.
