200 mm diameter sponge polishing wheel

In 1992, we innovatively developed soft polishing pads for granite, specifically tailored for the tombstone market, significantly enhancing polishing efficiency and gloss. In 2000, we registered the “Panshi Triangular” trademark. In 2004, we innovatively developed a new type of elastic abrasive pad (sponge polishing pad), meeting the marble market’s need to substantially reduce costs and minimize environmental pollution. In 2020, we registered the “Panshi Circular” trademark. To date, we have obtained more than ten utility model patents, including the “Eco-friendly Soft Polishing Pad for Granite.” In 2021, we developed the fourth-generation ultra-sharp soft polishing pad, which greatly improves grinding efficiency and quickly captured the domestic market.
