Micronized wax is a vital functional additive in industrial paint processing, with primary functions and mechanisms as follows: Enhancing abrasion resistance and scratch resistance: Micronized wax particles migrate to the paint film surface during film formation, creating a protective layer that reduces direct external force impact, significantly increasing the number of passes in RCA abrasion resistance testing. ‌Improved slip and tactile feel: Reduces surface friction coefficient, delivering a refined, smooth-to-the-touch finish. ‌Anti-blocking and anti-marring: Prevents coating adhesion during stacking or compression, suitable for packaging, woodwork, automotive interiors, and similar applications. ‌Matting and gloss control: Certain micro-waxes achieve a matt effect without compromising transparency. Dispersion stability and rheology modification: Polyamide wax micropowders form network structures to prevent pigment settling and enhance application levelling.

Gantry FSW Machine is a heavy-duty, high-precision friction stir welding system designed for large-scale industrial applications. Featuring a robust gantry structure, it delivers superior stability and welding force for joining aluminum, copper, magnesium, and other non-ferrous alloys. Unlike traditional welding, FSW produces defect-free, high-strength welds without melting the base material, making it ideal for critical structural components.

ROBOTIC FRICTION STIR WELDING Robotic Friction Stir Welding (RFSW) is an advanced solid-state joining technology that integrates friction stir welding (FSW) with a multi-axis robotic arm. Instead of melting the materials, RFSW uses a rotating tool to generate frictional heat and plastic deformation, creating high-strength joints between metals—especially aluminum, magnesium, and copper alloys. Product Advantages Precision, Efficiency, Intelligence Engineered for Unmatched Performance in Advanced Metal Joining

FRICTION STIR WELDING (FSW) TOOLS Friction stir welding tool is a critical component in the FSW process. It consists of a rotating shoulder and pin (probe) that generates frictional heat, softens the base material, and mechanically stirs it to form a solid-state joint. Unlike conventional welding consumables, FSW tools do not melt or deposit material. Instead, they facilitate precise plastic deformation and forge a high- integrity bond between workpieces without filler metals or shielding gases.
