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.

and sells a full line of wire drawing tooling, including large cased dies with cases up to 300mm (12") in diameter. It is also a major supplier of shaped dies to the global wire drawing industry, and makes other carbide tools used in the wire drawing process, such as shaving dies for high carbon valve spring wire, stainless and non-ferrous applications. Paramount has incorporated the scientific approach used in the The new PCD-TD product series, in the application field of stainless steel wire, has a lifetime claimed to be three to five times that of conventional PCD material. At present, the minimum pore size for mass production is 0.02mm. In the field of micro enamelled wire production, Geili’s enamelling die has been successfully applied to the coating of polyurethane, polyesterimide, polyimide, nylon and other insulating or self-adhesive materials with a size of 0.04 to 0.008mm. Compared with the microfilament coating method, mould coating can make the coating more uniform and

development of the ParaLoc holders and its wire drawing dies into the development of large dies, shape dies and shaving dies, aiming to provide improved productivity, higher quality and scrap avoidance. This approach is followed through the design, production, inspection and application of Paramount dies. Paramount Die Company www.paradie.com 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.

dies and draw dies in a single holder – the ParaLoc pressure system. The company says that this technology has enabled wire producers to increase productivity, improve finished wire quality and grow their businesses. In addition to dies for fine wire drawing in the size range of 5.5 to 0.5mm (0.218" to 0.02"), Paramount produces
