Beijing Hong Da Hard Materials Technology Research Institute is a high and new technology enterprise, which is approved by Beijing Municipal Science & Technology Commission. Founders of the institute are four engineers who graduated in 1960s, specializing in research and development of hard, wear-resistance and anti-corrosive materials, which including sintered carbides (tungsten carbide ) and high density ceramic materials ( boron carbide, silicon carbide ). Main products: sand blast nozzles, high pressure water spray nozzles, high pressure water cutting spray nozzles and so on. Non- standard products: seal rings and so on. The sale of sand blast nozzles hits 30000-60000.60%-80% nozzles among them exports to Europe, America, and Middle East.High pressure water spray nozzles (tungsten carbide insert) with excellent spray effect and long life time. The sale of high pressure water spray nozzles reached 1500-2000 sets per year. Users widely spread all over the country. Most nozzles export to South East Asia.Welcome old and new customers to join us.
