Polycrystalline diamond wire-drawing dies are drawing dies manufactured from synthetic polycrystalline diamond material. Owing to their unparalleled wear resistance, excellent overall mechanical properties—high strength and high toughness—and superior thermal conductivity, they have become the preferred choice for modern, high‑efficiency, high‑precision, large‑volume metal wire‑drawing operations. They significantly enhance production efficiency, reduce manufacturing costs, and improve the quality of wire products, serving as a key indicator of technological advancement in the wire‑processing industry.

Product Introduction

Application scenarios

Metal wire drawing: Suitable for the high-speed drawing production of various types of fine, medium, and some coarse metal wires, including copper, aluminum, tungsten, molybdenum, and steel cord.
High-precision wire processing: Used for manufacturing wires—such as electronic leads, welding wire, cutting wire, and spring wire—that demand stringent dimensional accuracy and surface quality.
Hard and difficult-to-machine materials: such as stainless steel wire, alloy wire, nickel-titanium wire, and other wire types that are challenging for conventional dies to draw.
Ultra-fine wire drawing: In the production of micro‑wires with diameters below 0.1 mm, polycrystalline drawing dies exhibit particularly outstanding uniform wear resistance.

Product Advantages

Extreme wear resistance: Polycrystalline diamond boasts a hardness nearly equivalent to natural diamond, and its tool life far surpasses that of cemented carbide—by a factor of dozens to hundreds.
Die‑shape stability: uniform wear, excellent wire‑diameter consistency, and high surface finish, significantly enhancing product quality.
High production efficiency: Reduces die‑change and die‑repair frequency, enables continuous high‑speed drawing, and minimizes downtime.
Excellent cost-effectiveness: Although the initial purchase price is higher than that of cemented carbide, its longer overall service life and lower maintenance costs significantly reduce the per‑ton drawing cost.
Highly adaptable: It can process a wide range of metal and alloy wires and is less prone to defects such as scratches and bamboo‑like surface irregularities.

Frequently Asked Questions

We offer free consultations to help resolve your issues.

What are the applications of functional diamond in the fields of thermal management and optics?

Diamond’s thermal conductivity is approximately five times that of copper and eight times that of aluminum, making it one of the materials with the best thermal performance currently known. The company’s functional diamond single crystals can be used in cutting-edge applications such as heat‑dissipating substrates for high‑power semiconductor lasers and 5G RF devices, optical windows for high‑power laser systems, and infrared thermal imaging systems.

What is the difference between lab-grown diamonds and natural diamonds?

Lab-grown diamonds are synthesized in a laboratory setting by replicating the natural diamond‑forming process using high‑pressure high‑temperature (HPHT) or chemical vapor deposition (CVD) techniques. They are chemically, structurally, optically, and physically identical to natural diamonds, with only subtle differences at the atomic level. Lab-grown diamonds offer advantages such as sustainability, traceability, and conflict‑free sourcing, while also commanding more competitive pricing.

Does the company support export operations? What certifications does it hold?

The company supports export operations, with a business scope that encompasses the import and export of goods. It has obtained ISO 9001 certification for its quality management system, ISO 14001 certification for its environmental management system, and ISO 45001 certification for its occupational health and safety management system. Additionally, the company has been recognized as a National High-Tech Enterprise, a “Specialized, Refined, Distinctive, and Innovative” SME in Henan Province, and a recipient of the Second Prize of the Henan Provincial Science and Technology Progress Award, among other prestigious accolades. Its products meet international standards.

Could you provide samples for testing? How do I apply?

Certainly. The company offers sample‑testing services to new customers, enabling them to evaluate product performance. Customers can submit their requests via the “Sample Request” page on our website or contact our sales team directly to discuss a customized testing plan. Sample dispatch takes 1–3 business days, and the samples are provided free of charge; customers are responsible only for the courier fees.

What are the product’s minimum order quantity (MOQ) and lead time?

The minimum order quantity for industrial diamond composite inserts and cutting tools varies depending on the specific specifications. Standard products are kept in ample stock, with a typical delivery lead time of 7–15 business days; custom‑made items require confirmation of the exact delivery schedule based on order volume and manufacturing requirements. For lab‑grown diamond products, in‑stock items are usually shipped within 3–5 days, while custom‑made orders take 7–15 days to ship.

What advantages do polycrystalline diamond compact (PDC), polycrystalline diamond (PCD), and polycrystalline cubic boron nitride (PCBN) inserts offer compared to similar products?

The company employs the world’s first 1,200-mm‑bore six‑face hydraulic press and advanced synthesis technology. Its products outperform comparable offerings by more than 20% in three key performance metrics—wear resistance, impact toughness, and high‑temperature stability—and boast a 25% advantage in dimensional accuracy. This enables a substantial increase in drill‑bit life and machining efficiency while reducing customers’ overall operating costs.

Which industries do your company’s products serve?

The company’s products are widely used in cutting-edge fields such as mining, geological exploration, oil drilling and production, jewelry and fine jewelry, precision machining, semiconductor thermal management, optical windows, and aerospace, serving multiple industries including energy exploration, high-end manufacturing, and consumer electronics.

What are your company’s main products?

The company focuses on research, development, and application across the entire spectrum of superhard materials, with its core business spanning two major segments: first, superhard composite materials, producing 3 million diamond‑based composite inserts annually, primarily including mining‑grade PDC, cutting‑tool PCD, cubic boron nitride PCBN, and specialized composites for oil and gas drilling; second, gem‑quality diamonds, encompassing colorless large single crystals, colored lab‑grown diamonds, and functional diamond single crystals, with the capability to synthesize lab‑grown diamonds up to 200 carats.
