Injection Mold Manufacturer in China — Multi-Cavity Specialists Since 2003
DFM feedback in 48 hours · Mold trials up to 3,300 tons · NDA before any data exchange
Ace Mould Company Ltd — also searched as Ace Mold Company — is an injection mold manufacturer based in Dongguan, China. Since 2003 we have designed and built precision molds for automotive, medical, cosmetics and packaging customers across the United States, Europe and Latin America. Our specialty is multi-cavity molds — from multi-cavity caps and closures to thin-wall packaging tools where cavity-to-cavity consistency decides whether a tool earns its keep.
For more than a decade our molds have run in production for the world’s most prestigious fragrance and beauty houses, for global FMCG leaders in dispensing systems, and for international medical-device manufacturers. We share references and walk through relevant projects in direct conversation — under NDA, which is exactly how your project will be treated too.
Mold Making Capabilities
- Cavity steel: S136, Stavax ESR, NAK80, H13, ASSAB 8407 Supreme — hardened to 48–52 HRC
- Hot runner systems: YUDO, Incoe, Mold-Masters, Synventive and Husky
- Tolerances to ±0.005 mm on critical dimensions, verified on Hexagon CMM
- Mold life guarantee: 1,000,000 cycles for SPI Class 101 tools
- Mold sizes matched to trial presses from 90 to 3,300 tons
Machining & Inspection Equipment
Our tool room runs high-speed YASDA and RÖDERS machining centers, FANUC and MAZAK CNC mills, and SODICK wire-cut and sinker EDM. Every mold is verified on a Hexagon CMM before trial, and ships with a full dimensional report.
In-House Mold Trials up to 3,300 Tons
Our molding floor operates 14 injection presses from 60 to 250 tons, all with robots and conveyors. For larger tools we guarantee trial capacity from 90 to 3,300 tons, so your mold ships with first-article samples and a full trial report — no surprises at your own press.

Frequently Asked Questions
What is your typical injection mold lead time?
Standard multi-cavity molds ship in 4–6 weeks from DFM approval, including in-house trial and a first-article inspection report.
Do you sign NDAs before quoting?
Yes. We sign an NDA before any drawings or 3D data are exchanged, which is also why customer molds are not shown publicly on this site.
What mold classes do you build (SPI 101–104)?
We build SPI Class 101 through 104 tools. Class 101 molds carry a 1,000,000-cycle life guarantee with cavity steel at 48–52 HRC.
Can you match an existing mold or part?
Yes. Reverse engineering is one of our specialties — we can measure an existing part or tool and build a matching or improved mold.
What files do you need for a quote?
3D data in STEP or IGES, 2D drawings with critical dimensions and tolerances, the plastic material, and your estimated annual volume. Our online quote tool also accepts STEP files directly.
Do you provide mold flow analysis?
Yes. Mold flow analysis and full DFM feedback are part of our standard engineering process before steel is cut.
