Mold making, molding and machining under one roof
Most buyers juggle a tool shop, a molder and a machine shop. We run all three in one Shenzhen building, so changes, trials and fixes stay with one team and one schedule.

Why Nodinson
How we compare with the usual ways to source a mold
Buying tooling from China should not mean losing control.
| What you need | Nodinson | Trading company | Local EU / US tool shop |
|---|---|---|---|
| Who makes the mold | Our own tool shop | Subcontracted, often unknown | In-house |
| Talk to the engineer | Directly, in English | Through a salesperson | Directly |
| Mold + molding + machining | All three, one building | Split across suppliers | Usually tooling only |
| Your standard (HASCO / DME / LKM) | Followed to your data sheet | Varies by subcontractor | Yes |
| Tooling cost & lead time | China cost, short lead time | Low price, extra margin | High cost, long queue |
| Approval before shipment | T1 samples + FAI report | Photos, sometimes | Yes |
FAQ
Questions buyers ask before starting a project
Straight answers on tolerances, sizes, standards, IP and shipping.
What tolerances can Nodinson hold on molds and molded parts?
Mold components are machined to 0.01 mm and molded parts are held to 0.02 mm on critical dimensions, verified on CMM. Steel components for machining customers can reach 0.005 – 0.01 mm. Achievable tolerance depends on resin shrinkage and part geometry, so we confirm it per feature during the DFM review.
What size of mold and part can you make?
We build molds from 98 kg up to 10 tonnes, with a maximum mold size of 1700 × 1500 mm. Molded parts range from 1.2 g to 10 kg, and the thinnest wall we mold is 0.5 mm.
Do you sign an NDA, and who owns the mold?
Yes. We sign your NDA before you send drawings, and most of our projects are confidential — the parts on this site are examples shared with permission. The mold you pay for is your property: it is marked with your part number and can be shipped to your own plant at any time.
Which mold standards and steels do you use?
Molds are built to HASCO, DME, LKM or the nearest DIN standard, or to your own data sheet. Typical steels are LKM 2767, 2344, 2311, 738H and 838H, ASSAB 718H and S136, DIN 1.2344 ESR and 1.2083 ESR, AISI H13 and 420 stainless, and Finkl P20 / P20HH. Hot runners can be Mold-Masters, Husky, HASCO, DME, YUDO, INCOE or Synventive. See our steel certificates.
Can you ship the mold to our own molding plant?
Yes. Many customers in Europe and the USA buy the tool only. Every mold is cleaned, marked, checked against a shipment checklist (cooling circuits, sprue, locating ring, ejection, support pillars) and packed for export. You receive T1 samples and a first article inspection report before shipment.
Do you mold low volumes as well as high volumes?
Yes. Quantities range from one prototype to thousands or millions of parts. For short runs we use family molds, P20 cavities cut into the plates or exchangeable inserts to keep tooling cost in line with volume. For high volume we use hardened steel, hot runners and multi-cavity layouts.
What is your T1 success rate and on-time delivery?
Up to 90% of our molds pass at the first trial (T1), and our on-time delivery rate is 95%. The reason is that we solve problems in the part design and the mold design before machining, instead of reworking steel after the trial.
Which file formats do you accept?
STEP, IGES, STL, Parasolid (X_T), DWG / DXF and PDF drawings. A physical sample or photos also work: our engineers can scan and redraw the part through our reverse engineering service.
