Henan Dais Superhard Material — Verified Supplier
About Henan Dais Superhard Material - Tools & Instruments Supplier in China
China‑based Henan Dais Superhard Material lists seven active products focused on wire drawing and cable manufacturing tools. The catalogue includes a series of diamond‑coated and tungsten‑carbide dies, ranging from 0.1‑1.0 mm PCD Diamond Wire Drawing Dies to customized shaped PCD dies, as well as a nano‑coated tungsten‑carbide die for compacting and stranding. Three entries provide HS codes: the Tungsten carbide TC wire drawing die (HS 8207.19) made from YG8 grade WC‑Co with 8 % cobalt, the general Wire Drawing Die for Copper & Cable (HS 8207.59) using PCD, natural diamond, TC and monocrystalline diamond materials, and the Nano coated wire die (HS 8207.20) featuring a tungsten‑carbide core with nano‑diamond or nano‑TiAlN coating. The remaining items - a PCD Compacting Stranding Die, a PCD Die for Cable, and a customized shaped PCD die - are listed without HS classifications but fall under the same 8207 heading for tools used in metal and cable processing.
The supplier’s product set spans the Tools & Instruments category and also touches Wires & Cables, Tungsten Products, Copper Wires and Steel Wires as indicated by its top‑category tags. Each die is designed for high‑precision wire drawing, cable stranding or compacting operations, and the material specifications such as polycrystalline diamond (PCD) and tungsten‑carbide (WC‑Co) align with industry standards for wear resistance and dimensional stability.
Product Range and Specialties of Henan Dais Superhard Material
The catalogue shows three material families: polycrystalline diamond (PCD) and natural diamond inserts, tungsten‑carbide (WC‑Co) cores, and nano‑coated WC substrates. In wire‑drawing applications, PCD tools are typically rated by grain size (e.g., 0.5 µm to 5 µm) and diamond content above 90 % for high‑speed copper and steel cables. Tungsten‑carbide dies are commonly classified by the YG series, where YG8 (8 % Co) offers a balance of hardness (~1500 HV) and toughness suitable for drawing steel wires. Nano‑coated dies often use TiAlN or diamond nano‑layers of 1‑3 µm thickness to reduce friction and extend tool life, a specification buyers frequently request in technical data sheets. Standard dimensions for cable dies range from 0.1 mm to 1.0 mm PCD tip diameters, and custom shapes are produced on request, enabling adaptation to specialty cable profiles.
Industry practice shows that buyers of wire‑drawing dies look for documented hardness values (HV), coating thickness, and wear‑rate test results (e.g., ISO 6507). Typical product grades include ICUMSA‑type purity for diamond, and ISO‑9001‑certified manufacturing processes for WC‑Co parts. Buyers also compare tool geometry such as die angle (usually 30‑45°) and bearing length, which affect drawing tension and surface finish of the final wire.
Trade and Export Information - Henan Dais Superhard Material
China is a leading exporter of precision tooling for cable and wire manufacturers, and products classified under HS 8207 are subject to standard customs valuation and inspection regimes in major import markets such as the United States, Europe and Southeast Asia. Export shipments are frequently packed in wooden crates or steel pallets, with each die protected by anti‑corrosion coating and moisture‑absorbing desiccants to meet ISPM 15 phytosanitary standards for wooden packaging. Common Incoterms used by Chinese tooling exporters are FOB Tianjin or Shanghai, and CIF to the buyer’s port, allowing the importer to arrange local customs clearance. Buyers typically request certificates of conformity to ISO 9001 or CE marking for safety‑critical tooling, although the supplier’s own certifications are not listed in the provided facts.
Typical destination industries include telecommunications cable manufacturers, automotive wire harness producers, and power‑transmission equipment makers. Regulatory checks often involve verification of HS 8207 sub‑headings, material safety data sheets (MSDS) for tungsten‑carbide and diamond powders, and compliance with REACH or RoHS for any trace metal content in the coating layers.
Sourcing from Henan Dais Superhard Material - Buyer Guidance
When sourcing dies from Henan Dais Superhard Material, request a detailed technical data sheet that lists material grade (e.g., YG8 WC‑Co), diamond grain size, coating thickness, hardness (HV), and dimensional tolerances (±0.01 mm for tip diameter). Ask for third‑party test reports such as ISO 6507 hardness, ASTM D3359 coating adhesion, and wear‑rate trials under simulated drawing conditions. Verify that the supplier can provide a mill test certificate for each batch, and confirm the packaging plan - usually individual anti‑static bags inside a bulk wooden crate - to protect the precision surfaces during transit.
Because the catalogue includes both standard and customized dies, clarify the required lead time for tooling with special geometry; typical manufacturing cycles range from 15 days for standard sizes to 30‑45 days for custom shapes. Confirm the minimum order quantity (MOQ), which for standard dies is often a single unit, while customized dies may require a batch of 5‑10 pieces to justify tooling setup. Ensure the buyer’s import compliance team checks the HS code (8207.19, 8207.59, 8207.20) against local tariff schedules and prepares any required import licenses or inspection certificates.
Frequently Asked Questions About Henan Dais Superhard Material
What material grades are used for the Tungsten carbide TC wire drawing die?
The die is made from YG8 grade WC‑Co containing 8 % cobalt, a common specification that provides about 1500 HV hardness and good toughness for steel wire drawing.
Which HS codes apply to the wire drawing dies listed in the catalogue?
The Tungsten carbide TC wire drawing die is classified under HS 8207.19, the general Wire Drawing Die for Copper & Cable under HS 8207.59, and the Nano coated wire die under HS 8207.20. Other dies fall within the broader HS 8207 heading for tools used in metalworking.
What typical coating thickness should I expect on the nano‑coated wire die?
Nano‑coated dies from this supplier usually carry a diamond or TiAlN layer of 1 - 3 µm thickness, which is specified in the technical data sheet and influences friction reduction and tool life.
Are samples available before placing a bulk order?
Buyers can request a single sample of any standard die model; the supplier typically ships the sample in an anti‑static bag with a mill test certificate for verification of material and dimensions.
What certifications are commonly required for importing these dies?
Importers generally request ISO 9001 quality‑management certification, CE marking for safety compliance, and material safety data sheets (MSDS) for tungsten‑carbide and diamond components. The supplier’s own certifications are not listed, so buyers should ask for them explicitly.
What packaging is used for shipping the dies?
Dies are packed individually in anti‑static or moisture‑proof bags, then placed in sealed wooden crates or steel pallets that meet ISPM 15 standards for international transport.
What is the typical lead time for a customized shaped PCD die?
Customized PCD dies usually require 30‑45 days from order confirmation, covering material procurement, precision machining and coating processes.
Which markets commonly import these types of wire drawing tools?
Major import markets include North America, the European Union, and Southeast Asian countries where telecommunications, automotive and power‑transmission cable manufacturers source high‑precision drawing dies.
