Our 55 gal PUR bulk melter adopts gradual heating and melting: The heating plate is located above the glue. When the heating plate is heated, only the upper layer of the glue barrel contacts the heating plate and reaches the melting point and melts. The lower part of the glue barrel does not melt at this time. To meet our requirement of melting as much as we need in production, the glue in the rubber barrel has a long pot life: the pot life can be up to 16 hours at 150°C and 3 days at 90°C. Over the years, the company's products have been well received by customers.
Our 5 gal PUR bulk melter adopts high-precision backflow valve (return valve sensitivity ±1bar), which is equipped with a locking function to avoid damage to equipment or personnel safety caused by operating errors. The filter design of the whole machine adopts heavy multi-layer filtering. It Can prevent the PUR glue from being outdated and causing blockage. Over the years, the company's products have been well received by customers.
