Hot Melt Adhesive or Thermoplastic Adhesive, has long been considered a commodity that is a very small part of packaging costs. Therefore the reduction in use has been of little priority. With the recent dramatic increases in hot melt prices customers have looked at ways to reduce the use of hot melt adhesive in packaging applications such as case sealing and carton sealing. One way to dramatically reduce hot melt adhesive consumption is to cycle the automatic applicator or gun so that the adhesive is applied in dots or elongated lines rather than long beads. The intermittent application can offer strong bonds and in many applications reduce the use of hot melt by as much as 50%. In order to cycle the adhesive properly you must have the correct pattern controller with intermittent output…

What causes the hot melt glue machine to block?
In order to prevent the hot melt glue machine from clogging, we are required to protect the core parts such as the glue tank from the beginning of the assembly to the completion of the assembly. Each assembly step is strictly in accordance with the production requirements to ensure quality, and test the machine before leaving the factory. But why will the main machine block afterwards? The reasons for the blockage of the main machine can be analyzed from 4 aspects: The filter in the glue tankof the hot melt glue machine is damaged and is not cleaned regularly, which causes blockage. The Teflon coating on the inner wall of the glue tank is peeled off or accidentally scratched. Once the Teflon is damaged, it is very easy to cause the hot melt adhesive to be carbonized and block during the…

Application of Hot Melt Glue Machine in Home Appliance Industry
Home appliances are ubiquitous in our lives, but do you know that it has high requirements for the bonding strength of glue? It needs water resistance, high temperature resistance and low temperature resistance, so the whole glue bonding process is very important. The main role of hot melt adhesives in the home appliance industry is to glued and sealed. With the widespread use of hot melt adhesives, the demand for hot melt glue machines is also increasing. For household appliances, such as televisions, DVDs, cameras, etc., many electronic components inside it need to be positioned, which requires fixed-point and quantitative glue application by hot melt glue machine; and for example ,lke the work piece parts and equipments of the white appliances, refrigerators, washing machines and air conditioners,it have some vibration inside, and the sound will become louder…

What is Hot Melt Adhesive?
Traditional hot melt adhesives (also known as thermoplastic adhesives) are one hundred percent solid, except when heated above a temperature of between 160°C and 180°C. The substance rapidly cools and sets, creating a quick and strong bond. The adhesives can be either very rigid or soft and pliable, depending on what the material is composed of. Hot melt adhesives are compounded from thermoplastic polymers and plastics. They are not affected by moisture, water, or humidity, unlike many other bonding agents. Hot melts are prominently used in the markets of automated manufacturing lines, packaging, converting, footwear, product assembly, bookbinding, and many more. The materials used to make up the hot melt adhesive usually depend on what purpose it will serve. Unlike solvent and water-based adhesives, there is no drying time with hot melt, so its uses are expanding…

How to Choose The Hot Melt Adhesives for Filter Assembly and Manufacturing
Effective filtration is becoming increasingly important in today’s world. Whether it’s the air inside your house, the drinking water in an urban metropolis or the fuel in a heavy-duty vehicle – filters are being asked to do more. In turn, filter manufacturers turn to us when they need to accomplish more with their filter adhesives. Air filters in vehicles and buildings are high-performance products. They ensure a constant supply of fresh and clean air. Filters are very diverse and are frequently composed of different materials. Powerful hot melt adhesives for the manufacture of filters are not only characterized by a broad range of adhesion to the different materials but also facilitate superior products and efficient manufacturing processes. How are hot melt adhesives used in filter assembly? Hot melt or water-based adhesives are used in the final stages of…
