LZ Carbide wire drawing dies, also known as TC wire drawing dies (Tungsten Carbide), are made from tungsten carbides of superior quality which are resistant to high heat and shock. At the same time, LZ cemented carbide drawing pellet are very cost effective compared with similar products.
LZ as the one of the biggest professional manufactures of Tungsten carbide drawing dies in China Which supplies all various types which are suitable for different wires drawing. We have strict quality control and assurance system to guarantee the consistent quality. We only produce the products which you satisfied.
Features: Tungsten carbide drawing dies is a class of materials widely used in drawing wires and rods because of their superior strength, toughness and wear resistance. All major wire producers can use drawing dies, which include wire drawing dies, tube drawing dies, bar drawing dies.
Type: S11, S13, LV,LE, W, and various sizes are as per China new technical standard. We can make suggestions of suitable grades for customers' usage.
Recommended grade: LL20/LZ10/LZ20/LZ25/LZ30/LZ50
Production Process:
Below are the production processes of blank solid tungsten carbide wire drawing dies, to ensure high quality, we assureed our customers that:
1. All materials are tested in terms of density, hardness and T.R.S before use.
2. Every piece of product goes through in-process and final inspection.
3. Every batch of product can be traced.
