What are the factors that can affect the improper use of drawing dies during the drawing process?

Mold production

The precision of mold making is directly related to the processing precision of the mold. During the mold making process, the wire drawing die is also affected by the wire drawing process parameters and the inherent design precision of the wire drawing die. For example, for the same product, wire drawing dies from different manufacturers, during processing, differences in wire drawing speed, heating temperature, and wire drawing pressure, etc., can all lead to changes in the surface quality of the wire drawing die.

Workpiece Material

Material of the workpiece affects the surface quality of the mold. Different materials have varying hardness levels, leading to different corrosion forces on the mold surface; workpieces of the same size also require different heating temperatures during processing, resulting in varying corrosion forces on the mold surface. For instance, when processing high-hardness, high-strength steel, the temperature should be relatively reduced.

Raw material

Raw material hardness has an impact on mold surface corrosion as well. Experience shows that when the hardness of the raw material is between 65-70, the friction with the mold surface is low; however, if the hardness exceeds 70, surface blemishes and scratches may occur. Above 75, increased friction resistance leads to more pronounced surface blemishes and scratches.

Operation

During the drawing process, the drawing speed has a significant impact on the mold face corrosion. Improper operation or other factors causing the drawing mold speed to be too fast can result in surface oxidation, while too slow speed can lead to uneven drawing.

Other Factors

Are there significant gaps? Are there scratches or marks on the mold? These issues can affect product quality, and we must pay attention to them.
