The copper sleeve offered by Dongguan Jinpan Mould Parts Co., Ltd. is a precision‑engineered component fabricated from electrolytic tough pitch copper with a purity of 99.9%. It is supplied in a range of custom dimensions that can be matched to buyer drawings, and the material provides excellent thermal and electrical conductivity for demanding environments. The product is marketed for bulk procurement, allowing international buyers to source large quantities for OEM and aftermarket programmes.
Electrolytic tough pitch copper is the preferred grade for high‑conductivity applications because it delivers a typical conductivity of about 58 MS/m and a tensile strength near 210 MPa. In the industry, sleeves of this grade are used where low resistance and reliable heat dissipation are critical, such as in power distribution and heavy‑duty machinery. Typical outer diameters run from 10 mm to 50 mm with wall thicknesses between 0.5 mm and 2 mm, and the supplier can adjust these parameters to suit specific fittings.
Primary users include manufacturers of electrical connectors, plumbing assemblies, HVAC equipment and automotive subsystems. Dongguan Jinpan can arrange shipment under CIF or FOB terms, and while the listing mentions flexible minimum order quantities, exact figures should be confirmed directly with the supplier. Prospective buyers are encouraged to request material test certificates and to discuss any required packaging formats before finalising the order.

Before placing an order, importers should request the mill test report and any applicable certification that confirms the 99.9% copper purity and IEC 60228 compliance. Verifying the exact outer diameter, wall thickness and length against the supplier's engineering drawing will avoid costly re‑work later in the production line.
Logistics arrangements typically involve CIF or FOB terms, but the exact incoterm, lead time and payment schedule must be agreed with Dongguan Jinpan. Lead times for custom‑moulded sleeves are often in the range of four to six weeks, subject to the complexity of the dimensions and current production load. Payment is commonly made via T/T in advance or after inspection, depending on the buyer’s risk tolerance.
Quality control is essential for copper sleeves used in critical systems. Importers should consider a third‑party inspection at the factory and require a certificate of conformity together with the mill test report before shipment. Proper documentation, including a packing list and commercial invoice, will facilitate smooth customs clearance and ensure the product meets the buyer’s technical specifications.
