Melting Unit for Hot Melt Glue Applicators
The melting unit, also referred to as a fusion unit, is a critical component of production lines integrated with a hot melt glue spreader. It ensures the melting, heating, and precise temperature control of industrial adhesives, including hot melt thermoplastic adhesives, reactive PU (polyurethane) adhesives, and PSA adhesives (Pressure Sensitive Adhesives).
The melting unit guarantees stable viscosity, consistent adhesive flow, and uniform application, which are essential conditions for accurate, reliable, and repeatable bonding processes.
Melting Unit for Standard Hot Melt Adhesives
- Role: Heat and melt solid hot melt adhesives (blocks, granules, or pellets) to obtain a fluid adhesive ready for application.
- Operation: The molten adhesive is transferred by pumps to the applicator guns of the hot melt glue spreader, then evenly applied to the product via coating or application rollers.
- Objective: Ensure a consistent and uniform adhesive flow, enabling fast, precise, and continuous bonding.
Melting Unit for Reactive PU (Polyurethane) Adhesives
- Role: Heat and maintain the isocyanate component or pre-formulated PU adhesive at the optimal temperature to achieve ideal application viscosity.
- Function: Ensure homogeneous conditioning and uniform application of the adhesive before its chemical curing process begins.
- Objective: Guarantee process repeatability, minimize the risk of clogging, and precisely control the reactivity of reactive PU adhesives.
Melting Unit for PSA Adhesives (Pressure Sensitive Adhesives)
- Role: Gently heat certain solid or highly viscous PSA adhesives to facilitate transfer and application.
- Function: Maintain controlled viscosity to ensure smooth application without excessive thickness or air bubble formation.
- Objective: Deliver immediate and uniform adhesion, which is essential for self-adhesive products.
