Its catalogue includes computer category mold, green category mold, appliances mold, generic mold, auto category mold and power tools category mold. Each entry falls under the broader HS chapter 84 classification for machinery and equipment. The supplier is classified as an imported tier with a harbor trust rating.

Product Range and Specialties of Shanghai Zishuo Plastic And Mold Co., Ltd.

The supplier’s six mould types cover distinct market segments. Computer category moulds target housings for laptops, desktops and peripheral devices, where surface finish of Ra 0.8 µm and tight dimensional control are common. Green category moulds are used for environmentally‑focused products and often employ recycled‑grade plastics, requiring mould steel with corrosion‑resistant treatments. Appliances moulds serve kitchen and home‑appliance components, typically demanding larger cavity dimensions and higher clamp forces up to 1500 kN. Auto category moulds are built for automotive interior and exterior parts, with material grades that withstand higher temperatures and repeat‑injection cycles. Power‑tools category moulds produce housings and ergonomic grips that must meet impact‑resistance specifications. The generic mould entry can be adapted to various applications and is usually offered with interchangeable core plates.

Trade and Export Information - Shanghai Zishuo Plastic And Mold Co., Ltd.

China is a major exporter of plastic processing machinery and moulds, classified under HS 84.5 for injection‑moulding equipment. Export shipments frequently go to Europe, North America and Southeast Asian manufacturing hubs, where automotive, consumer‑electronics and appliance assemblers source tooling. Buyers typically require ISO 9001 quality‑management certification and, for EU markets, CE conformity assessment for safety and environmental compliance. Standard export documentation includes commercial invoice, packing list, certificate of origin and, when requested, a third‑party inspection report such as SGS or BV. Common logistics involve FOB Shanghai or CIF destination ports, with cargo packed in wooden crates on 20‑ft or 40‑ft containers to protect the precision components during sea transit.

Sourcing from Shanghai Zishuo Plastic And Mold Co., Ltd. - Buyer Guidance

When sourcing moulds from this supplier, buyers should request detailed engineering drawings that specify cavity layout, cooling channel geometry and ejection system design. Verification of the tool‑steel grade (e.g., P20, H13) and heat‑treatment certification helps assess durability for the intended production volume. Sample moulds or prototype runs are advisable to confirm surface finish, dimensional accuracy and cycle time before full‑scale order. Requesting an ISO 9001 certificate and, if applicable, a CE declaration of conformity provides a baseline for quality compliance. Confirm the minimum order quantity, typical lead time of 8‑12 weeks for new tooling, and packaging details such as crate dimensions and pallet configuration.

What product categories does Shanghai Zishuo offer?

The catalogue lists six mould types: computer category mould, green category mould, appliances mould, generic mould, auto category mould and power‑tools category mould. All items belong to the plastic processing machinery sector.

Which certifications should a buyer verify for these moulds?

Buyers should ask for the supplier’s ISO 9001 quality‑management certificate. For markets that require it, a CE declaration of conformity may also be needed.

What material grades are typically used for the moulds?

Injection moulds are commonly manufactured from tool steels such as P20, H13 or S136. These grades provide the hardness and thermal resistance needed for high‑volume plastic production.

What is the usual lead time for a new mould?

After the final design is approved and a deposit is received, lead times generally range from eight to twelve weeks. Complex multi‑cavity designs may extend the schedule.

What are the typical packaging and shipping methods?

Moulds are packed in reinforced wooden crates placed on standard Euro pallets. Shipping is usually arranged in 20‑ft or 40‑ft containers under FOB Shanghai or CIF terms.

What minimum order quantity applies?

The supplier accepts a single mould as the minimum order. However, larger cavity counts or multi‑cavity configurations may affect production planning.

How can a buyer obtain a sample or prototype?

Buyers can request a prototype run based on supplied CAD data. Sample cost and lead time are confirmed after the design is validated and any required tooling adjustments are made.
