Natural Diamond Wire Drawing Die

The diamonds used have been carefully selected, the quality is very good, and the hardness is very high, with high wear resistance, suitable for thinning.

Brief Introduction

The diamonds used are of high quality and have been strictly selected. There are no cracks or impurities in the diamond. It surpasses most of the diamond in terms of hardness and toughness. Reduces the risk of cracking to the greatest extent and prolonging the service life of the die. In addition, due to the extremely high hardness, this also greatly improves the quality and efficiency of the wire products.

FAQ:
Wire breakage during drawing
1. Wires have impurities: need to strengthen the acceptance of raw materials.
2. Poor lubrication: The lubrication system needs to be checked to determine the composition and temperature of the lubricant.
3. The shape of the die hole is incorrect or not smooth: the die needs to be repaired strictly according to the standard, and the bearing should not be too long to ensure the finish of the blank.
 
 

Product Application

·Suitable for drawing precision wires and precious metals
The diamonds used by our company are of excellent quality and the diamond surface is absolutely regular. It is suitable for drawing products with small diameters, such as precision wire and precious metal jewelry.
The drawn products are of high quality, accurate shape, and due to the small friction, the surface finish of the drawn jewelry is extremely high.


·Drawn magnetic wire
The magnet wire has high requirements in terms of quality, and in the drawing process, the temperature requirements are extremely strict. Since the diamonds we use are carefully selected, the loss of raw materials in the process of drawing products is very small. The produced magnet wire fully meets the quality standards.
