Technological development
Before 2008, the traditional PVC coating process has been coated with cold glue. The main reason is that the softening temperature of PVC coating film is about 80 degrees. It cannot withstand the glue application temperature of EVA hot melt adhesive as high as 180 degrees. REHOW Textile Machinery actively promotes the new process of wrapping PVC with PUR hot melt adhesive, which is widely used in bonding, so as to break the shackles of cold glue wrapping PVC with low efficiency, slow speed, high rejection rate, and long curing time.
PUR hot melt adhesive laminating machine with a coating temperature of 130 degrees to 150 degrees PUR hot melt adhesive is used to complete the coating process of textiles, industrial products, aluminum profiles and other PVC with a softening temperature of about 80 degrees. The main points are The coating machine manufactured by REHOW Textile Machinery can run at high speed and stably, and its self-developed unique structure of rubber scraping head.
Process characteristics
The coating machine manufactured by REHOW Textile Machinery has a stable overall body and a precise transmission system. After careful adjustment before leaving the factory, the working speed can reach 60 m/min. 120 m/min, its high efficiency, fast speed, and stable operation are difficult to match even some German equipment; moreover, the squeegee head independently developed by Babelan has simple structure, smooth glue output, and convenient maintenance , It is also the original boutique that those imitators are vying to copy. In the actual production process, when the PVC coating film quickly slides over the squeegee head with a high temperature of 130-150 degrees for precise glue discharge, there is no time for the PVC material to absorb a large amount of heat energy, so as to ensure that the PVC coating film does not deform, Do not stretch.
With a stable overall body and a precise conveying system, the covering machine manufactured by REHOW Textile Machinery Co., Ltd. does not need any form of deviation correction device when working at a speed below 60 m/min, and the adjusted equipment can be started for production at any time, thus saving Lots of material and time. The PUR hot melt coating machine produced and sold by our company adopts the American Nordson glue gun, with a production speed of 60m/min, professional technology, and dedicated service for you.
technical comparison
At present, many cold glue coating companies have switched to hot glue coating for production, mainly because hot glue coating has obvious advantages compared with cold glue coating, including:
1. High work efficiency. The process of cold glue determines that the moisture in the glue must be evaporated during the coating process, so the phenomenon of “bubbling” is likely to occur if the working speed is too fast. Generally low. Hot glue coated products do not need to be stored and observed, and the speed is much faster than cold glue machines. The production efficiency of Babelan hot melt glue coating equipment is 3 to 5 times that of domestic cold glue equipment.
2. Low labor cost. The running speed of the cold glue equipment is slow, and multiple equipments need to be configured to meet the production demand. This requires a large number of workers to meet production demands. It not only leads to waste of land occupation, but also drives up labor costs. The number of operators of Babelan hot melt adhesive coating equipment is the same as that of ordinary cold glue equipment, but the efficiency is greatly improved. During the one-year production period, the direct labor cost can save more than 300,000 yuan.
3. Glue-saving and easy to adjust. The automatic electronically controlled gear pump glue supply system can precisely control and digitally display the amount of glue per gram when the coating is constantly changing. The design makes the equipment extremely easy to adjust and easy to handle. The amount of sizing in actual production is more than 10% lower than that of similar domestic products.
It is because of the many advantages of the equipment in the production process and the good reputation of REHOW Textile Machinery that our equipment is in an absolute leading position in the industry, and many entrepreneurs insist on choosing REHOW Textile Machinery.
The annual output of REHOW textile machinery reaches more than 300 sets of equipment, which are exported to Southeast Asia, the Middle East, Europe, North America and other countries and regions.
To sum up, the coating machine manufactured by REHOW Textile Machinery Co., Ltd. uses PUR hot-melt adhesive together, which brings the PVC coating process into a new era, which is several times higher than that of cold glue in terms of production efficiency, stable product quality and labor cost. A large number of savings have won the trust of more and more business decision makers. In today’s environment where labor costs and corporate production capacity are constantly increasing, the PVC coating process has changed from cold glue coating to PUR hot melt adhesive coating. is an inevitable trend.
