Import Bi-Injection Mould-China Mold Maker — Buy in Bulk from Supplier in China

Dalian Mintadely mould Co., Ltd produces bi-injection moulds for two-component or two-colour plastic part forming, a process that injects two distinct polymers sequentially within a single moulding cycle to achieve integrated multi-material components. The mould incorporates rotating core sets or transfer mechanisms to position the first-shot substrate for overmoulding by the second material, with hot runner manifolds typically maintaining polymer temperature independent of mould temperature control. The source cites application in automotive interior trim, semiconductor IC connectors, lead frames, and motor fixed-rotor assemblies where material bonding or functional soft-touch surfaces are required.

Mould construction centres on precision-ground tool steel cavities and cores, with typical core steels including AISI H13 or ASSAB 8407 for heat resistance and uniform hardness, and cavity inserts in P20 or NAK80 depending on polish and wear requirements. Bi-injection tooling demands tighter inter-cavity alignment than single-shot equivalents, with typical parting line repeatability below 0.02 mm and concentricity between first and second shot governed by rotating plate mechanism accuracy. The source notes ISO 9001:2008 certification and ERP-managed production scheduling, though the certificate scope, accreditation body, and current validity should be confirmed directly with the supplier.

Buyers for this tooling tier include tier-one and tier-two automotive suppliers, consumer electronics OEMs requiring multi-material housings, and electric motor manufacturers integrating insulated rotor assemblies. Dalian Mintadely cites prior supply to Mercedes-Benz, BMW, Audi, Honda, Toyota, Volkswagen, Nissan, and Mazda programmes, though buyers should request programme-specific references and part numbers to verify claim substance. Lead times, mould life guarantees in shot counts, and warranty terms are not stated; these must be clarified before purchase order issuance.

Dalian Mintadely mould Co., Ltd is headquartered at No.10-11-3, Northeast Seven Street, Economic Development Zone, Dalian, Liaoning 116100, China, a location within the Dalian Development Area that clusters automotive and precision manufacturing suppliers with port access to the Yellow Sea. The company was established in 2006, giving it approximately nineteen years of operational history in Chinese mould-making. Trust tier is listed as harbour, and response rate registers at zero on platform metrics; buyers should therefore rely on directfidirect email or telephone enquiry to gauge current sales engineering responsiveness rather than platform-mediated messaging.

The supplier operates a design department, laboratory, testing centre, and R&D team, and applies ERP for production scheduling and quality traceability. It cites ISO 9001:2008 certification, though this version was superseded by ISO 9001:2015; buyers should request the current certificate status and any IATF 16949 automotive quality system registration if automotive supply is the intended application. Customer references to Mercedes-Benz, BMW, Audi, Honda, Toyota, Volkswagen, Nissan, and Mazda are claimed; these should be validated through direct reference checks with named programme contacts rather than accepted at face value, as Chinese mould makers sometimes overstate OEM relationships.
