From Weak Bonds to Permanent Fixes: Plasma Surface Treatment Equipment Success Stories

Many manufacturers struggle with hot melt glue peeling off polypropylene or treated cardboard. The solution is often not the glue, but the surface. Plasma surface treatment equipment has turned weak bonds into permanent fixes across multiple industries.

Case 1 – Automotive interior trim

A dashboard supplier using Keqirui’s hot melt glue system saw intermittent bond failure on PP substrates. After installing inline plasma surface treatment equipment, bond strength increased by 400%, and field failures dropped to zero.

Case 2 – Medical device assembly

A catheter manufacturer needed a solvent-free bond between silicone and a thermoplastic. Plasma activation allowed hot melt glue to adhere directly, passing cytotoxicity and peel tests.

Case 3 – Packaging

A corrugated box producer switched from water-based adhesive to hot melt glue plus plasma treatment, tripling line speed and reducing glue consumption by 30%.
