The 12 questions buyers ask us most.

Send your part file (STEP/IGS/STL 3D or even a photo with dimensions), plus material, expected annual volume and target price if you have one. The fastest route is our RFQ form — it collects exactly what we need. You get a DFM opinion, tooling concept, price and lead time within 48 hours. No template quotes.

There is no MOQ on mould making — we build from a single tool to a full production programme. For injection moulding service (parts production) in our workshop, small trial batches are welcome, especially for T1 validation runs.

Typical lead time is 4–12 weeks depending on size and complexity: a household bin or crate mould runs 4–6 weeks; a multi-slider automotive interior trim mould with lifters runs 10–12 weeks. T1 sample timing is confirmed in writing before the deposit is paid, and we report progress with photos weekly.

A mould price = design hours + steel + machining time + slotting + trial. The big variables are steel grade, cavity count, expected cycle life, cooling design and surface finish requirement (e.g. SPI or textured). When one supplier quotes 40% lower, usually the steel grade, cooling layout or ejection design has been simplified — ask them to specify these five items and compare like-for-like.

Common choices: P20 / 1.2311 for general tooling, 718H / 1.2738HH for large household parts, H13 / 1.2344 for high-volume or glass-filled materials, S136 / 1.2083 stainless for medical and optical surfaces. We recommend based on your resin, annual volume and surface requirement — and we state the steel grade in the quotation so you can verify it on delivery.

Written guarantee by class: Class 101 tooling rated 1,000,000+ shots (high-volume automotive), Class 102–103 for 500,000–1,000,000, Class 104–105 for prototyping volumes. If the mould fails under normal use within the guaranteed cycle count, we repair or replace the affected components free of charge.

Standard is 30% deposit with PO, 40% after T1 sample approval, 30% before shipment. For repeat customers we offer 30/70. We accept T/T bank transfer and support USD settlement through XTransfer for compliant, low-cost cross-border payments.

Yes. Send the physical sample — we 3D-scan it and rebuild the part model, then proceed with DFM. For 2D drawings we model the part in UG/NX and confirm critical dimensions with you before tool design starts. Every tool gets a Moldflow analysis before cutting, so filling, warpage and weld-line risks are caught while changes are still cheap.

Every mould is trial-run in our workshop before packing. You receive T1 samples by express (DHL/FedEx) plus a full trial report. FAI (First Article Inspection) comes standard; CPK measurement on critical dimensions is available for automotive customers. Moulds ship only after you approve the samples.

Moulds are packed in fumigation-free wooden cases with anti-rust treatment, shipped by sea from Ningbo or Shanghai. We quote FOB, CIF or EXW — most customers take FOB. Moulds and plastic parts can ship in the same container to save freight.

We sign an NDA before any file transfer, on request. Your part files are never shared, never reused for another customer, and never used to make competing products. Since 1998 we have tooled for automotive OEM tier-suppliers who audit confidentiality yearly.

Both. Most customers take the mould and run it at their own moulder; we also offer in-house injection moulding for validation runs and ongoing production. If you want, we keep and maintain your mould in our tool room between production campaigns — including cleaning, rust-prevention and spare-part replacement.
