Injection Mold Manufacturer in China
HC-Mold designs and builds custom plastic injection molds in Chang'an, Dongguan, from rapid tooling for launch volumes to multi-cavity production molds. Every tool starts with a free DFM review and mold-flow analysis, and when the mold is approved we either ship it to your molder or run production in the same plant.

We sign an NDA before any file review. Complete packages get a reply within 12 hours and a quote within 24 hours. See the injection mold RFQ checklist.
Types of injection molds we build
One tool room covers validation tooling, production molds and specialty molds, so the mold matches the part, the resin and the volume instead of a fixed catalog.
Production injection molds
Single-cavity, multi-cavity and family molds in pre-hardened or hardened steel, with cold or hot runner systems sized to your annual volume and cycle-time target.
Rapid tooling
Simplified molds in about 15 days to validate a design, run pilot builds or launch at low volume before you invest in production steel. Compare rapid tooling vs a production mold.
Insert molds
Threaded inserts, pins, contacts and other metal components are placed in the mold and encapsulated in plastic, removing secondary assembly steps.
Two-shot (2K) and overmold tools
A rigid substrate and a soft-touch TPE or TPU layer molded into one part for grips, seals and housings. See overmolding vs insert molding.
LSR molds
Liquid silicone rubber injection molds for seals, gaskets, keypads and soft-touch components where heat resistance and flexibility matter.
Die casting molds
Dies for aluminum and zinc die casting, with machining of the cast parts in the same plant. See die casting production.
How we make an injection mold: from RFQ to approved tool
Each step has a written output you can review, so problems are found on screen rather than in steel.
NDA & RFQ
NDA signed before file review. Quote within 24 hours on a complete package.
DFM review
Draft, wall thickness, gate location, undercuts and ejection checked, free of charge.
Mold-flow analysis
Fill, weld lines, cooling and warpage simulated before steel is cut.
Mold design
3D tool design with cavity layout, runner, cooling and ejection, approved by you.
Steel & machining
Cores and cavities CNC machined and EDM finished, then polished or textured.
T0 trial
Internal trial on the press; the tool is adjusted before samples leave the plant.
Approval & handover
Production molding at HC-Mold, or the mold is packed and shipped for export.

Choosing mold steel and cavity count
Steel, cavities and runner type decide most of the tool price and its life. We recommend a configuration in the DFM report; the table below is general guidance, not a quote.
| Program stage | Typical tool | Typical steel |
|---|---|---|
| Design validation, pilot build, launch volume | Rapid tool, single cavity | Pre-hardened steel such as P20 |
| Steady production | Production mold, single or multi-cavity | P20, 718H or 738H pre-hardened |
| High volume, glass-filled or abrasive resins | Hardened multi-cavity mold, hot runner where cycle time pays | SKD61 (H13); NAK80 for high-gloss surfaces; E420 stainless for corrosive resins or clean-room parts |

Export molds or production in the same plant
You decide where the approved tool runs.
Export injection molds
The mold is built to the LKM, HASCO or DME standard you specify, proven on T1 samples with a dimensional report, and packed for shipment to your molder. Read how to choose an export injection mold manufacturer in China.
Molding at HC-Mold
The approved tool moves straight to injection molding production in the same plant, with capacity from 50 to 500,000+ parts per month and one quality system from first sample to repeat orders.
Injection mold cost and lead time
Mold price is driven by part size, geometry and undercuts, cavity count, steel grade, runner system and surface finish. A small single-cavity rapid tool and a hardened multi-cavity hot runner mold can differ by an order of magnitude, so we quote from your 3D file rather than a price list.
- How much does an injection mold cost? Price factors and ways to reduce tooling cost.
- Injection molding cost per part: material, cycle time and tooling share.
- Lead time: rapid tooling about 15 days, standard molds 25–35 days, confirmed before you place the order.
Industries we build molds for
Consumer and household products, electronics enclosures, automotive components, medical and electronic devices, and industrial equipment, for brand owners and OEM engineering teams in North America, Europe and beyond.
Injection mold FAQ
How much does an injection mold cost?
It depends on part size, complexity, cavity count, steel and runner system. Send a 3D file and we quote within 24 hours on a complete package. The injection mold cost guide explains each price factor.
How long does it take to make an injection mold?
Rapid tooling takes about 15 days and a standard mold 25–35 days, depending on complexity. The timeline is confirmed before the order is placed.
How long will the mold last?
Molds carry a 300,000+ shot warranty. For higher volumes we select hardened steel for up to 1,000,000 cycles.
Will you sign an NDA before I send drawings?
Yes. A confidentiality agreement is signed before any file review, and drawings are never shared with third parties. See IP protection and NDA.
Who owns the mold?
HC-Mold offers three tooling models: buyer-paid tooling that you own and can move with written notice, tooling funded by HC-Mold against an agreed purchase volume, and tooling whose cost is refunded from product payments. See who owns the mold.
Can you ship the mold to our molder?
Yes. Export molds are built to the mold base standard you specify, proven on T1 samples and packed for shipment.
Do you make two-shot, insert and LSR molds?
Yes. We build insert molds, two-shot (2K) overmold tools and liquid silicone rubber (LSR) molds in addition to standard thermoplastic molds.
What is the MOQ for molded parts?
Injection molding typically starts at 500–1,000 parts per run. For smaller quantities we recommend rapid tooling, vacuum casting or CNC machining.
