Hot melt adhesive film laminating equipment is mainly divided into two types in terms of working methods, pressing type and composite type.
1. Pressing equipment
Scope of application, only suitable for sheet materials, not for roll lamination, such as clothing signs, shoe materials, etc.
Pressing processing characteristics
The pressing type is relatively higher in pressure, it can use the mold to fit the shaped material, and can have the function of shaping, but it cannot be continuous operation, and the production efficiency is low
The possible factors that affect the bonding effect during the hot melt adhesive film bonding process include uneven temperature, uneven pressure, and poor thermal conductivity of the heating plate or heating mold in each area. The advantage of relative composite is long heating time.
2. Compound equipment
Hot melt adhesive film laminating equipment can be divided into roller laminating machine and flat laminating machine
Scope of application: The roller is suitable for the lamination of coils, and the flat plate is suitable for both sheets and coils.
Composite processing characteristics: continuous production and bonding, high bonding efficiency and effective avoidance of air bubbles that may be generated in the pressing type bonding. The factors that affect the bonding effect during the bonding process include insufficient roller pressure, excessive speed, and The temperature of the heating roller is uneven.
There are more than so many fields of hot melt adhesive film. I want to know more about finding peace and hot melt adhesives. Customer first and meeting customer expectations are the reasons for our existence. Professional innovation, hot melt problems, give Jiangsu Hehe hot melt adhesives, Professional manufacturer.
