Company Profile

Zhejiang Humo Polishing Grinder Manufacture Co.,Ltd. was established in 1986. It has more than 350 employees. The factory covers an area of 125,500 M2, with an annual output of more than 40,000 tons of polishing blocks, more than 4,000 sets of polishing machines and polishing fluids. More than 8,000 tons, it is a large domestic production and export base of light-grinding abrasive materials, and its production scale is also in the forefront of the same industry in the world. In 2014, the total industrial output value was 260 million yuan, and the profit and tax was 40 million yuan. The company's products are mainly used in machinery, electronics, instrumentation, aerospace, automotive, motorcycle, daily hardware, handicrafts, accessories, casting, forging, medical equipment and many other industrial fields. In addition to selling well all over the country, more than 50% are exported to more than 50 major industrial countries and regions such as the United States, Japan, South Korea, the European Union, Turkey, Southeast Asia and South America. Among them, it has been exported to the US market for 20 years, and currently ranks among the top in the industry in the US.

        Based on more than 30 years of experience in the industry, the company has also actively penetrated into related industries in the field of technology in recent years – wear-resistant ceramic zirconia beads and dispersants for ultra-fine grinding. This product is mainly suitable for ultra-fine grinding of non-metallic mineral powders such as heavy calcium carbonate, kaolin and talc. The company selects high whiteness and high-fineness raw materials to ensure non-contaminated materials, and adopts a unique roll-forming process to improve the sphericity and density of the products, ensuring no cracking, combined with advanced kiln firing technology. The long-term high-temperature sintering forms a wear-resistant microcrystalline structure, which ensures stable performance during use. Among them, zirconia microbeads have high specific gravity, high efficiency, high toughness, good impact resistance, good chemical stability, and low wear on mechanical equipment. The specific gravity can reach 4.0g/cm3 or even 6.0g/cm3, Rockwell hardness. Up to 118-124, the wear is no more than 0.0028% per hour. It is applied to high-end fields of fine processing related to minerals, chemicals, paints, machinery and electronics, filling domestic gaps, replacing imported products and exporting foreign exchange. After the launch of related products, it has been well received by the market. After several years of hard work, it has already occupied 80% of the national market share of the industry.
