1. Melting and Mixing
The raw materials are heated to a molten state and fully mixed in sigma mixer to ensure that the components are evenly fused. At this time, the temperature in the reactor needs to be precisely controlled according to the melting point of the raw material.
2. Extrusion Molding
The evenly mixed hot melt glue is extruded from the screw and extruded into continuous glue strips or glue threads through the die.
3. Cooling
The extruded hot melt glue strips are quickly cooled and solidified in the cooling system to ensure the stability and hardness of the particles.
4. Pelletizing
The cooled glue strips are fed into a pelletizer and cut into particles of uniform size by a high-precision tool.
5. Screening and Shorting
The cut hot melt glue particles are screened to remove unqualified particles to ensure the uniformity and consistency of the particles.
