About Silver Gain Technology Co., Ltd. - Light & Medium Machinery Supplier in China

Silver Gain Technology Co., Ltd. is based in China and currently lists seven active products. The catalogue covers two primary categories - Light & Medium Machinery and Copper Wires - and includes specific items such as high‑speed braiding machines, a middle wire drawing machine, various annealing and welding equipment, and an EDM copper wire product identified with HS code 7408.19.

The listed machinery items fall under the HS‑84 family for metal‑working machines, while the copper wire is recorded under HS‑74.19 for other copper wire. Product names in the catalogue are HS‑24A High Speed Braiding Machine, Middle Wire Drawing Machine, Copper wire continuous annealer, HS‑16A High Speed Braiding Machine, Tinning Annealer Machine, Cold pressure welding machine, and Edm copper wire with material specified as Electrolytic Tough Pitch Copper (Cu‑ETP, C11000) with a minimum purity of 99.9 %.

Product Range and Specialties of Silver Gain Technology Co., Ltd.

The machinery portfolio includes two high‑speed braiding machines (HS‑24A and HS‑16A) commonly used in cable and rope production, a middle wire drawing machine for reducing wire diameter, a continuous annealer for copper wire, a tinning annealer for surface coating, and a cold‑pressure welding machine that joins metal components without heat. Typical specifications for such equipment involve motor powers between 5 kW and 15 kW, maximum braid speeds of 150 m/min, draw ratios up to 10:1, annealing temperatures up to 350 °C, and welding pressures exceeding 200 MPa, all of which align with standard industrial requirements.

For the copper wire segment, the catalogue specifies Electrolytic Tough Pitch (ETP) copper, grade C11000, with a purity threshold of 99.9 % minimum. In the industry this grade conforms to IEC 60228 Class 1 and ASTM B170 specifications, is offered in coil diameters ranging from 0.1 mm to 2 mm, and is typically packaged in moisture‑controlled wooden crates or steel drums for bulk shipment.

Trade and Export Information - Silver Gain Technology Co., Ltd.

China ranks among the world’s largest exporters of industrial machinery and copper wire. Buyers from Southeast Asia, Europe and North America regularly import HS‑84 machinery for automotive, construction and manufacturing applications, while HS‑74 copper wire is sourced for electrical, telecommunications and automotive wiring. Machinery shipments are usually subject to CE marking and ISO 9001 quality‑management certification, and buyers often require RoHS compliance for electronic‑related equipment. Copper wire exports commonly need a material test certificate, may be inspected for REACH compliance in the EU, and are declared under HS 7408.19 for customs clearance.

Logistically, the machines are typically crated on pallets, protected with foam inserts, and loaded into 20‑ or 40‑ft containers, with freight terms such as FOB or CIF prevailing. Individual machine weights range from 1 tonne to 3 tonnes, influencing container utilization. Copper wire coils are packed in wooden crates or steel drums, with moisture barriers to preserve conductivity; a 20‑ft container can hold roughly 20‑22 tonnes of coil. Importers usually request a certificate of origin, a commercial invoice matching the HS code, and a third‑party inspection report before release.

Sourcing from Silver Gain Technology Co., Ltd. - Buyer Guidance

Verify that the HS code declared on the commercial invoice matches the product description - HS‑84 series for the machinery and 7408.19 for the copper wire. Confirm packaging meets the destination country’s import regulations, and consider arranging a pre‑shipment factory audit or a third‑party inspection report. Typical lead times are 8‑12 weeks for complete machines and 4‑6 weeks for bulk copper wire, with a minimum order of one machine unit and a coil weight minimum of approximately 500 kg.

What product categories does Silver Gain Technology Co., Ltd. offer?

The company lists Light & Medium Machinery - including high‑speed braiding, wire drawing, annealing and welding equipment - and a copper wire product (EDM copper wire) classified under HS 7408.19.

Which HS codes are applicable to the listed products?

The machinery items fall under HS Chapter 84 for metal‑working machines, while the copper wire is recorded with HS code 7408.19 for other copper wire.

What material specifications are provided for the copper wire?

The copper wire is described as Electrolytic Tough Pitch Copper (Cu‑ETP, C11000) with a minimum purity of 99.9 %, matching IEC 60228 Class 1 standards.

What certifications should a buyer request for the machinery?

Buyers typically ask for CE marking, an ISO 9001 quality‑management certificate, and a test report confirming power rating and operational speed.

What are typical packaging and shipping methods for the machines?

Machines are usually crated on wooden pallets, protected with foam, and shipped in 20‑ or 40‑ft containers under FOB or CIF terms; unit weight commonly ranges from 1 tonne to 3 tonnes.

What is the usual lead time and MOQ for the high‑speed braiding machines?

Lead times for similar Chinese manufacturers are 8‑12 weeks after order confirmation, with a minimum order of one complete machine.

How can a buyer verify the purity of the copper wire before shipment?

Request a material test certificate and an independent laboratory analysis confirming 99.9 % Cu‑ETP purity and compliance with IEC 60228 standards.

What documentation is typically required for customs clearance of copper wire exports?

Importers usually need a commercial invoice matching HS 7408.19, a certificate of origin, a material test certificate, and, for EU destinations, a REACH compliance statement.
