As professional manufacturer and supplier for WPC door making machine, Yongte supply turnkey project for WPC door production. Except our high quality WPC door and door frame extrusion machines, we also supply the lamination machine, CNC engraving machine, sanding machine, cutting machine and other auxiliary equipments. for lamination machine, there are cold glue lamination and hot glue PUR lamination machine, We suggest the WPC door manufacrturing factory equip the PUR hot glue lamination machine considering for better quality WPC door and lower production cost.
The production speed of cold glue coating machines is generally 10 meters per minute, while that of hot glue coating machines reaches 30 meters per minute. For large-scale production orders, one hot glue equipment unit achieves the work efficiency equivalent to three cold glue machines. In terms of output, hot glue equipment reduces labor requirements by replacing two cold glue machines. With an average of 4 workers needed per coating equipment, this translates to saving 8 labor positions daily. Based on an average daily wage of 100 yuan per worker, hot glue equipment reduces labor costs by 800 RMB per day.
The market price of cold glue is approximately 4 USD/kg with a usage rate of 100 grams per square meter, while PUR hot melt glue is priced at around 8.6 USD/kg but only requires 40 grams per square meter. Additionally, cold glue machines necessitate glue box cleaning every time the film is changed or the machine is stopped, resulting in significant waste. In contrast, PUR hot melt glue machines only require glue box cleaning during extended shutdowns, thereby achieving lower overall glue costs compared to cold glue systems.
Cold glue machines require a certain distance for glue drying after coating, resulting in approximately 4 meters of film waste during startup, shutdown, or film changes. In contrast, hot glue machines only waste 1 meter of film under the same conditions, leading to lower overall film costs compared to cold glue systems.
Cold glue contains chemical solvents that release irritating gases when volatilized, posing risks to workers and the environment. In contrast, PUR hot melt glue is a zero-pollution product, giving finished goods a competitive edge in sales. Additionally, PUR hot melt glue undergoes an irreversible curing reaction, resulting in superior bonding strength compared to cold glue.
Hot glue equipment incorporates a professional hot melt gluing system, resulting in a higher initial purchase price compared to cold glue equipment. However, the cost difference is offset by the long-term savings in labor, glue, and film expenses. Specifically, while a basic WPC door frame cold glue machine may cost around 6,000 USD, a high-quality WPC door frame hot glue machine with similar capacity is priced at approximately 20,000 USD. Despite the 14,000 USD price gap, the daily savings of 800 RMB (around 120 USD) in labor costs alone (as calculated earlier) allow the hot glue equipment to recover its additional cost within just 4 months of continuous operation. When factoring in reduced glue and film waste, the payback period becomes even shorter, making hot glue equipment a more cost-effective investment in the long run.
In the equipment price comparison, despite the higher initial investment required for hot glue equipment, its long-term cost-effectiveness becomes clearly evident. The substantial daily savings in labor costs, combined with reduced waste of glue and lamination film, result in a rapid payback period. This makes hot glue equipment a financially viable and advantageous choice for long-term operational needs.
