Company X, as a professional manufacturer of stainless steel precision parts, has long been troubled by problems such as tool sticking and rapid wear during thread processing, and frequent tool replacement affects production capacity. According to the customer's working conditions, Chuanhao seiko recommended the use of powder metallurgy (HSSE-PM) taps, using Chuanhao's independently developed heat treatment process, and combined with TiCN coating to further significantly improve the hardness, wear resistance and red hardness of the taps, so that the processing volume of a single tap has increased from 500 pieces to 1,500 pieces, and the customer's production capacity has increased by 30%. Due to the stable processing quality, it has obtained orders for high-end locomotive parts, and the scale of cooperation has expanded year by year.
