Import Auto Category Mold — Buy in Bulk from Supplier in China

Shanghai Zishuo Plastic And Mold Co., Ltd. produces auto category molds for manufacturers serving the automotive sector. These tools shape interior components, exterior panels, and functional elements from plastics and metals. The molds are built to withstand repeated injection or pressing cycles without premature wear. Typical cavity hardness for automotive injection molds runs HRC 48-52, though buyers should request the exact Rockwell rating from the supplier. Cooling channel layout, venting design, and parting line placement all affect cycle time and part consistency.

The base material is typically pre-hardened tool steel or alloy steel, with cavity and core inserts in hardened grades such as P20, 718H, or S136 depending on production volume and resin type. Runner systems may be cold or hot, with the latter reducing material waste for high-volume programs. Ejection systems use pin, blade, or sleeve configurations matched to part geometry. Surface finish requirements for visible automotive parts usually demand SPI A-2 to D-3 grades, so buyers should specify their required gloss or texture standard. Tolerance classes follow ISO 2768-m or tighter, depending on the component's fit and function.

Buyers of auto category molds include Tier 1 and Tier 2 automotive suppliers, electric vehicle startups, and aftermarket parts manufacturers. The mold is a capital investment that directly determines unit cost, cycle time, and part quality over its service life. Before committing, buyers should request DFM (Design for Manufacturability) review, mold flow analysis, and a detailed maintenance schedule. Packaging for shipment typically involves wooden crates with moisture barriers; confirm crate dimensions and gross weight with Shanghai Zishuo Plastic And Mold Co., Ltd. for freight planning.

Shanghai Zishuo Plastic And Mold Co., Ltd. is located at No.58 Lianxing Road, Huangdu, Jiading, Shanghai 201804, China. The supplier is classified as an imported-tier vendor on the platform with a harbor trust tier. The response rate shows 0.00 percent and average response time is zero hours, which suggests either new account status or inactive inquiry handling. Buyers should initiate contact to assess current responsiveness and English-language capability before planning factory visits or technical discussions.

The source description indicates capability in precision and durable mold construction for automotive applications, though no specific certifications, annual output figures, or client references are provided in the data. The company mentions compatibility with plastics and metals, advanced design capabilities, and complex shape formation. Buyers should verify actual CNC machining capacity, EDM capability, CMM inspection availability, and quality management system registration directly with the supplier. No verified ISO or CE certificate numbers appear in the source material, so request copies and check validity through issuing bodies.
