Hot Melt Adhesive Scraper Coater

Hot melt adhesive coating machines melt solid adhesive through heating and use a scraper to evenly apply the molten adhesive onto the surface of a substrate. They are used for the composite processing of materials such as paper, fabrics, and plastic films to achieve material bonding or surface lamination.
Selection
When selecting, consider the width of the substrate to match the equipment specifications, determine the temperature control range based on the melting point of the adhesive, and choose the adhesive feeding system according to the production speed. The type of doctor blade should be suitable for the viscosity of the adhesive, and regular cleaning of residual adhesive can ensure uniform coating.
