Ms. Guo

Zibo ZiYi Metal Materials Co., Ltd. was founded in 2013, mainly engaged in 304, 410, 430, 201 and other stainless steel wire, stainless steel cut shot, carbon steel wire cut shot, cast steel cut shot, cast steel cut shot, alloy precision casting materials, and other products and related equipment parts and accessories research and development, production and sales. The company's annual production of stainless steel, carbon steel and other steel wire 8000 tons, 6000 tons of steel shot. The products cover 10 categories of more than 120 specifications. The products are widely used in shipbuilding, casting, machinery, locomotive, die-casting, steel structure and other industries, recognized and praised by the majority of customers, and become the designated supplier for a number of enterprises.

Our company has a professional full-process steel shot production process. All raw material suppliers are strictly controlled in accordance with the ISO quality system. The incoming metal coils are still inspected and analyzed according to standards. Before drawing, the surface is strictly cleaned (by using cleaning agents or mechanical methods). The drawing process is precisely controlled following the mechanical properties of the material. The Ra value of the wire surface is reduced from several microns of the coil to about 1.0 micron. The self-developed silent automatic cutting machine cuts the wire into steel shot particles with consistent length and diameter. The proportion of shot particles with a length-to-diameter ratio greater than 2 is controlled below 5%. According to user requirements, through cyclic rounding, the G1, G2, and G3 standards are reached. Finally, the formed steel shots are screened and classified to ensure the consistency of shot particle sizes. The dimensional accuracy of steel shots is strictly controlled within a range of ±0.05mm, fully meeting users' precise requirements for the size of cut shots.
