Import Diamond Wire Drawing Die Blanks — Buy in Bulk from Supplier in United States

The product is a diamond‑coated wire drawing die blank supplied by Henan E‑grind Abrasives Co., Ltd. It is manufactured under ultra‑high temperature and ultra‑high pressure conditions, combining synthetic diamond powder with a cobalt metal catalyst. This construction gives the blanks exceptional wear resistance, hardness, thermal conductivity and mechanical strength. The blanks are offered in two product families, the CDB series and the TDBY series, each available in five grain‑size grades of 3 µm, 5 µm, 10 µm, 25 µm and 50 µm.

In the wire‑drawing industry such dies are valued for their ability to reduce drawing force and to produce a smoother surface finish on conductive metals. Typical diamond‑coated dies for copper, aluminium, nickel or stainless‑steel wires operate at temperatures up to 600 °C and require a hardness of at least 9 Mohs, which aligns with the specifications of these blanks. The cobalt binder provides good toughness, allowing the die to withstand the high tensile stresses encountered during multi‑pass drawing. These blanks are classified as standard industrial diamond tools and conform to the usual ISO 18325 grading for diamond grit.

Buyers such as wire manufacturers, cable producers and precision‑forming facilities can integrate the blanks into their drawing lines to improve productivity. The supplier lists the product without a disclosed minimum order quantity, price or lead time, so interested importers should request those details directly. Packaging is typically supplied in sealed steel drums or wooden crates to protect the brittle diamond surface during transit. Payment terms, incoterms and shipping arrangements are negotiated per order and should be confirmed before finalising the purchase.

Henan E‑grind Abrasives Co., Ltd. is registered at Room 1841, Tower A, Wanda Plaza, 171# Zhongyuan Road, Zhengzhou City, Henan Province, China, with an additional United States address listed in the source data.
