Used household mould

When purchasing used moulds, you must verify the steel grade (e.g., P20, 718, or S136) to ensure durability. Check the cavity number to match your production capacity and inspect the cooling system for blockages. It is critical to request the mould life history, specifically the shot count, to estimate how many cycles remain before significant maintenance or failure occurs.

You must confirm the mould dimensions (length, width, and height) fit within your machine's tie-bar spacing. Additionally, verify the locating ring diameter, ejection system type (mechanical or hydraulic), and clamping force requirements. Requesting a 3D design file or mold map is essential to ensure your technical team can integrate it without costly modifications.

Perform a dry cycle test to check for smooth movement of sliders and lifters. Inspect the parting line for wear, which causes 'flash' on finished products. You should also request a T1 sample trial video and physical samples to check for dimensional accuracy and surface finish quality. Ensure there is no visible rust or pitting in the cavities that could affect the aesthetic of household items.

Ensure the mould is designed to produce items that meet BPA-free or Food Grade (FDA/LFGB) standards if the household items are for kitchen use. The mould itself should have safety interlocks and clear identification plates. If sourcing via Made-in-China.com, look for Audited Suppliers who provide ISO 9001 certification to ensure their refurbishment processes meet international quality benchmarks.

The biggest risk is hidden damage or 'fatigue' not visible in photos. To mitigate this, always use a third-party inspection service (like SGS or Intertek) before final payment. Ensure the transaction is protected by Trade Assurance or secure payment terms to prevent financial loss if the mould arrives in a non-functional state.

Focus your negotiation on the refurbishment scope. Ask the supplier to include replacement of wearing parts (springs, O-rings, copper bushings) in the quoted price. For bulk purchases of multiple moulds, aim for a 15-20% discount, but prioritize a guarantee of a successful trial run over the lowest possible price.

Moulds are heavy and prone to rust during sea transit. Insist on anti-rust oil coating and vacuum plastic wrapping. The mould must be secured in a fumigated wooden box with internal bracing to prevent shifting. Clearly define the Incoterms (e.g., CIF or FOB) to understand who bears the risk during the long-haul maritime journey.

Many countries have strict regulations on used machinery imports. You must check if your local customs require a Pre-shipment Inspection Certificate (PSIC). Ensure the HS Code (typically 848071) is correctly declared and that the commercial invoice reflects the depreciated value accurately to avoid legal complications or excessive duties.
