Product Details

The polycrystalline diamond (PCD) wire drawing dies produced by Uking Diamond utilize top-tier raw materials, including imported premium diamond blanks such as Japanese SUMIDIA and American COMPAX (GE). This guarantees consistent structural integrity and eliminates micro-fractures under high pressure.

Our manufacturing process combines selected diamond micropowder blended with a precise metallic catalyst (cobalt). This mixture is sintered under ultra-high pressure and high-temperature (HPHT) processing conditions. Under these strictly regulated metallurgical controls, the microcrystalline particles form a robust diamond-to-diamond bond (D-D linkage). This gives our PCD dies exceptional hardness, structural isotropy, and high thermal conductivity equivalent to natural single-crystal diamonds (ND).

Because the internal diamond grains are randomly oriented, our PCD microstructures are entirely isotropic. This eliminates directional wear orientation problems, providing significantly higher structural toughness, impact resistance, and prolonged die service life compared to traditional tungsten carbide drawing dies.

Key Features

Nano-Level Surface Polish: An ultra-fine, mirror-polished inner surface drastically improves wire surface quality, eliminates die-marks, and prevents line scratching.
Advanced Pre-treatment Technology: Special interface treatments create a super-strong diamond adhesion matrix, preventing blank delamination even during high-impact line adjustments.
Extended Tool Life: Exceptional abrasion resistance vastly reduces the frequency of die changes, maximizing your automated continuous drawing machine uptime.
Ultra High-Speed Drawing: Maximizes wire throughput speeds and elevates production capacity without sacrificing cross-sectional dimensional stability.
Simplified Coolant & Lubrication: Designed to work smoothly with standard water-based cooling media or generic drawing lubricants, ensuring minimal thermal wear and maintaining clean operating media.

Are you experiencing frequent wire breakage or surface scratching during high-speed drawing below 0.1mm?

Poor inner geometry and unstable diamond blank adhesion are the hidden killers of automated drawing efficiency, causing micro-shavings that degrade your wire finish.

At Uking Diamond, we don’t just supply dies—we design tailored solutions. Our engineering group calibrates precise reduction angles and bearing lengths based on your specific wire tensile strength (MPa) and continuous machine drawing speed.

FAQ

Q1: What is a PCD wire drawing die, and how does its buy-value compare with tungsten carbide dies?

A: A PCD (Polycrystalline Diamond) wire drawing die utilizes an HPHT-sintered polycrystalline diamond nib mounted within a robust carbide or steel casing. Unlike natural diamond, PCD consists of numerous diamond crystals randomly bonded together, providing an isotropic microstructure that eliminates the risk of directional cleavage failure. Compared with conventional tungsten carbide (TC) tools, choosing to buy wire drawing dies made of PCD typically provides a 10–50 times longer service life, lower bore wear, and a superior wire surface finish in copper, aluminum, and other non-ferrous fine wire applications. This extreme durability makes them the ultimate asset when long production runs and minimized tooling costs are required.

Q2: What wire materials and bore sizes can I source from UKing Diamond as a specialized wire drawing die supplier?

A: As a dedicated global wire drawing die supplier, UKing Diamond manufactures high-performance PCD dies tailored for an expansive matrix of processing industries, including:

Copper & Copper Alloys: Magnet wire, bare copper wire, brass wire, and communication cable conductors.
Aluminum & Aluminum Alloys: Power cable conductors, electrical transmission wire, and aluminum wire rod.
Precious Metals: Fine gold, silver, platinum, and specialty medical alloy wires.
Refractory & Specialty Alloys: Tungsten, molybdenum, nickel alloys, and stainless steel wire.

Standard factory bore diameters range from 0.05 mm to 25 mm. Additionally, custom die geometries, customized bearing lengths, and approach angles are tailored by our engineering team to match your specific line speeds and continuous drawing tensions.

Q3: Can PCD wire drawing dies be reconditioned, and what factory support does the manufacturer provide?

A: Yes. Implementing a strict preventative maintenance schedule and periodic reconditioning will significantly extend the operational campaign life of your tooling. To protect the critical bearing zone, regular ultrasonic cleaning is recommended to remove lubricant residue and metallic dust from the die bore. When the internal geometry exceeds your wire gauge tolerances, UKing Diamond—as a fully integrated wire drawing die manufacturer—provides professional regrinding and relapping services to restore original bore alignment, mirror surface finish, and drawing performance. This factory reconditioning program allows the diamond module to be safely reused for multiple production cycles, dramatically lowering your total tooling investment cost per drawn kilometer.
