We are one of the few plastic injection mold makers in China that specialize in mold making cost-effective custom injection molding and custom design tooling for injection molded plastic parts, compression molds, over-molding, and molds for investment casting. Innovative custom design mold making solutions such as our CAD plastic injection mold design services in China. Our custom design tooling manufacturing in China, and mold making export program ensure a low upfront cost, high-quality solution for our clients custom design tooling projects.

Tooling and mold making in China is our preferred manufacturing method for our customers when the time will allow. We feel by offering custom design tooling in China we can give our customers quality steel tools for the price they would pay for aluminum tools in the US or Europe. We can make molds and tools in China to run at our plastics facilities, or to ship to your location.

We offer custom design tooling for OEMs, end-users, injection-molded plastics shops, and injection mold makers at our engineering facilities in China. Our experienced engineers allow us to maintain the high quality of our injection mold-making services while keeping costs low. We also work with many U.S. and European design firms producing tools for them and will not sell our design services to their customers.

Cnmoulding designs and mold making its clients’ custom tools, die’s, and molds to their specifications, produce new molds from its customers’ CAD files, or reverse engineers existing parts. As one of the premier injection mold makers, we are very proficient in reverse engineering in many parts. We have many different 3D design software platforms to adapt to our customers’ systems. Digital data files and computerized machining are used almost exclusively for the tooling of custom molds.

For small and extremely large parts, which can be manufactured specifically for small or dedicated long-run production molds, provide high-quality custom design tooling. Cnmoulding is one of China’s best custom mold-making manufacturers, specializing in Die Casting and Injection Molds for export. We can manufacture tools that are multi-cavity molds, unscrewing molds, closure molds, hot-runner molds, and stack molds.

Plastic Mold Making

Plastic Injection Mold Making Process
In China, a long-standing tradition of export mold manufacturers, we share here the basic injection mold making overview:



1. Parts Design (client may provide completed 3D files)
The tooling process begins with a completed and checked part design. CNMOULDING can optionally optimize your design before tooling to lower your costs and ensure that your design will work well.

2. Parts Prototyping (if necessary)

If you would like to validate your parts design with a machined piece that you can see and feel, CNmoulding can use Computer Numerical Control (CNC) techniques to prototype your parts.

3. Tool / Mold Design

At this stage the tool is designed, using the information from your completed tools and molds design

4. Tool / Mold Check and Mold Flow Analysis
The tool design is validated for correctness.

5.Tool / Mold Fabrication

(including use of Computerized Numerical Control (CNC) and Electrical Discharge Machining (EDM) technologies)
The tool is precisely fabricated according to the validated design.

6. New Injection Molds First Shots To Client
Once the injection molds are made, the first test shot samples will be sent out soon after via an international courier. Once sent, these usually take around 2-5 days to arrive.

7. Tool / Mold Modifications and Texturing
At this stage, the Mold shop completes the tool and makes any required changes to bring the tool into the approved spec. Changes made to bring the tool to spec (specifically excluding design changes, which are always charged) are made free of charge.
At this stage, texturing also takes place, which is normally the last stage before mass production.

8. Mass Production Run or Export
At this stage, parts are produced and delivered to the customer, or the tool is released for export use.

Technical Topics:
Molding begins with tooling. No matter how good the design, if the tooling is not up to the task. The quality of the parts will suffer.
