Lowering the minimum diameter of metal wire drawing dies

Geili is a die manufacturer dedicated to R&D and production of ultra-fine wire drawing dies. Its die products, which have obtained 16 patents, include polycrystalline diamond dies, natural diamond dies, enamelling dies, shaped profile dies, and bunching, compacting and stranding dies. By 2020, the company had more than 120 employees, realising annual production and sales of 400,000 die products. Geili has added to its range of micro stainless steel wire drawing dies with a natural diamond wire drawing die with a minimum diameter of 0.005 ±0.00002mm. The new PCD-TD product series, in the application field of stainless steel wire,

self-adhesive materials with a size of 0.04 to 0.008mm. microfilament coating method, mould coating can make the coating more uniform and effectively reduce the use and emission of solvents, which can better protect the environment. Geili is equipped with stable laser drilling equipment, precision testing equipment (SEM, CU10, DM300, etc) and an all-round wire drawing experimental centre that can provide customers with many kinds of metal material drawing solutions.
