Company Overview

ZiYi Metal Materials

Production Process

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 selfdeveloped 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 classifed 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.
