Tungsten carbide dies are often used in rod drawing industry. Rod drawing is a process that a rod will go through a single or series of drawing dies to reduce the cross section of a rod. The dies are placed in a steel casing with tungsten carbide as inner "nib".
Many years of experience and commitment to research and development enables Miller to offer a range of tungsten carbide grades to meet the drawing requirements for all applications. We can design reasonable compression area angle and sizing area length to reduce the drawing force and friction force, increasing the service life.
To ensure rod high-quality and control the cost of rod drawing dies effectively, Miller Carbide suggests below 4 aspects:
1) Reasonable collocation of molds: Select proper hole type of the mold, adjust the compression angle appropriately according to the size reduction rate.
2) Rod pretreatment: Cleaning, rust removal, annealing, phosphating etc. to ensure the rod clean.
3) Good lubrication: Select high quality lubricating oil or powder to reduce friction and friction heat effectively.
4) Timely replacement: Repair or replace the mold that reached its service life, to avoid the rod scrap.
