Large Width Slot Coating Scraper Gun For Continuous Wide Surface Lamination

Keqi wide slot scraper hot melt gun features a maximum scraping width of 35mm, dedicated to full-surface uniform hot melt coating for mattress fabric composite, foam lamination and large hardbox lining bonding. The linear slot outlet delivers thin, flat glue film without local accumulation or missing coating.

Constant temperature heating block prevents slot clogging caused by cooled residual glue. Adjustable scraper clearance precisely controls coating thickness to save adhesive consumption. Pneumatic lifting structure allows quick gap adjustment when switching substrates of different thicknesses. Compared with multiple dot guns, the slot scraper achieves seamless full-surface bonding, eliminating gaps between glue dots on soft foam and textile materials. It matches mattress production lines, rigid gift box lining machines and automotive interior composite equipment perfectly.
