When purchasing drawing dies, we always hope that the products we buy are the best. If there are no defects, then it is the best product. Therefore, we must learn to analyze the quality of drawing dies. Just by looking at it, you can choose the most suitable drawing die for yourself. From a price perspective, natural diamond drawing dies must be more expensive, but the price is also higher because this type of drawing die is more complex in processing. Natural diamond drawing die heads have high hardness but can easily cause conflicts, so this type of die head can only be used on certain smaller diameter materials, but its wear resistance is the best. There is also a hard alloy die. This die has lower hardness, its appearance is not very rough, but its wear resistance is poor and its hardness is relatively low, so it is generally not recommended to choose to purchase. Choosing a drawing die is like choosing an explosion-proof electric heater. You must be very careful. Only by paying attention to it can you find your center.
Quality factors of self-processing lead to rapid wear of molds:
1. The asymmetrical embedding of the wire drawing mold blank and the mold steel sleeve, with uneven distribution of the embedded hard alloy steel sleeve and gaps, causes U-shaped cracks only during the wire drawing process of the mold.
2. During the laser drilling process of the diamond mold blank, unclean sintering marks or uneven force can cause pits in the diamond mold during the drawing process.
3. Unreasonable mold hole planning, with an opening that is too small in the smooth area at the entrance and an excessively long slurry band, will result in poor smoothness during the drawing process, leading to accelerated wear or even breakage of the drawing mold head.
