Hot melt after melting with inert gas or air into the metering pump mixing, output to the glue gun. The external circulation part of the glue gun flows back to the melting cylinder and re-enters the gear pump. Equipped with manual glue gun machine internal cycle foaming. Foam efficiency By nitrogen or air conditioning, the foam efficiency is up to 50% with special foam. Achieve glue saving 35 -
45% (see plastic selection model). The flexibility of the glue is better, not broken, the product sealing is better, similar to the sponge. The host computer is driven by servo. The machine is mainly used in honeycomb filter, household air purifier, household refrigerator, air conditioner, electronics, automobile and other industries foam sealing.
