PUR hot melt adhesive is also known as moisture curing reactive polyurethane hot melt adhesive. It encounters moisture in the air and will undergo an irreversible cross-linking reaction. Even if it is heated again, it will not melt. Therefore, the PUR hot melt adhesive machine is in use In the process, the sealability of the glue is very important. The PUR hot melt glue machine is an automatic PUR special glue application equipment. There are currently 5 gallons and 55 gallons. The precision metering pump forms a smooth surface, beautiful appearance, strong resilience, good dust and waterproof performance, and sealing protection level. High and environmentally friendly hot-melt adhesives make the lid more precise and faster.
We know that the processing size and accuracy requirements of the sealing ring are extremely strict. Small size will lead to poor sealing performance, and large size will not install it. At present, there are many models and shapes on the market, and the selection range is also large. Customization is often required, and customization often requires re-opening the mold, which leads to an increase in production costs and is not conducive to the long-term development of the enterprise.
