Intaglio Hot Melt Coating Machine

A hot melt dot coating machine for making anti-skid mats and anti-slip multi-wall storage bags is a specialized industrial system designed to apply precise patterns of hot melt adhesive onto substrates.

1. Anti-skid mats:

o Used in warehouses, workshops, packaging areas.

o Require a durable, patterned grip surface.

2. Anti-slip multi-wall bags:

o Bags used for packaging materials like cement, grains, chemicals.

o Dot coating provides friction to prevent bag slippage during stacking.

Machine Features

Hot Melt Tank Melts and maintains adhesive (typically EVA, PSA, or rubber-based hot melt).

Temperature Control System Ensures stable operation to prevent over- or under-heating.

Web Handling System Transports materials like PP/PE fabric, paper, or film through the coating zone.

Pattern Control (PLC-based) Allows for adjustment of coating density and distribution via HMI screen.

Speed Control Adjustable to suit different substrates and production speeds.

Slot Die and Roller Coating makes it even and uniform all over the surface.

Suitable Materials

• Substrates: Woven PP fabric, kraft paper, nonwoven fabric, PE film.

• Adhesives: EVA, APAO, PSA, or rubber-based hot melt adhesives.

• Coating width (commonly from 300 mm to 1600 mm)
