PU hose can be both rigid and soft
Hot melt glue machine uses high temperature to heat solid glue strip or particle to a molten state. And it extrudes molten glue with pressure to achieve the purpose of bonding. It contains heating system, spraying system, control system, etc. The heater in the heating system will convert electrical energy into heat energy. This increases the ambient temperature and melt the glue. The spray system will precisely spray the molten glue onto the product. While the control system is responsible for the operation of the entire equipment and the flow control.
Material classification of hot melt glue machine hoses
Polyurethane hose
Polyurethane hose has excellent wear and pressure resistance with high tensile strength. Therefore, it is suitable for high temperature and high pressure hot melt adhesive machines. In addition, the inner diameter of PU hose is more precise. Thus it can benefit the flow and spraying of glue. And it widely serves in automobile, furniture and other fields.
Silicone hose
Silicone hose has excellent high temp and corrosion resistance. Therefore, it is suitable for highly corrosive hot melt adhesive. In addition, silicone pipe is flexible. Thus it can reduce the impact of the pipeline to the equipment and extend the service life. Because of these, silicone hose widely serves in electronic, automobile, etc.
Polyethylene hose
PE hose has good wear, impact and corrosion resistance. Therefore, it is suitable for low pressure and low temperature hot melt adhesive machine. PE hose has low density and light weight. So it is easy to carry and install. Therefore, it is widely used in packaging, printing and other industries.
Fluorine rubber hose
Fluorine rubber hose has excellent high temp, corrosion, acid and alkali resistance. Besides, it has high tensile strength and wear resistance. Thus it can ensure the quality and stability of the glue. Therefore, it has a wide range of apps in aerospace, chemical, etc.
