Dongguan Changdong Tool & Die Co., Ltd. is a metal stamping die manufacturer and tooling supplier focused on custom stamping die design, die manufacturing, CAE analysis, CNC machining, WEDM cutting, die assembly, tryout and sample validation.
Since 2012, Changdong has supported automotive, appliance, industrial and electrical projects with progressive dies, transfer dies, single-operation dies, prototype dies and sheet metal stamping solutions.
Changdong is not only a stamping die factory, but also a manufacturing partner that connects engineering review, tooling design, machining, assembly, tryout and production feasibility validation. Our work focuses on helping customers turn sheet metal part drawings into practical and stable stamping tooling solutions.
Dongguan Changdong Tool & Die Co., Ltd. was founded in 2012 and moved to a 4,000 square meter facility in 2015. The company focuses on custom metal stamping dies and stamped metal parts for projects where tooling accuracy, forming stability, dimensional control and production reliability are important.
As a custom stamping die manufacturer, Changdong supports customers from early part review to die tryout. This helps identify forming risks, tooling structure issues and manufacturability concerns before the die enters mass production.
Long-term focus on stamping die engineering, tooling manufacturing and stamped metal part production support.
Integrated manufacturing space for die design, machining, assembly, tryout and validation work.
Supports progressive dies, transfer dies, single-operation dies, prototype tooling and stamped metal parts.
Changdong is supported by an engineering team experienced in stamping die design, forming analysis, strip layout, tooling structure and process planning. For complex sheet metal parts, engineering decisions made before machining can strongly affect die tryout time, sample quality and production stability.
| Engineering Area | How It Supports the Project |
|---|---|
| Die Structure Design | Defines die type, station layout, working components, guide structure and maintenance approach. |
| CAE Forming Analysis | Helps evaluate cracking, wrinkling, thinning, material flow and springback risk before tooling adjustment. |
| Strip Layout and Process Planning | Supports progressive die and transfer die process planning for stable part movement and forming sequence. |
| Tryout Feedback | Connects sample results, dimensional inspection and die adjustment before final validation. |
A reliable stamping die supplier should not only machine die components. The supplier must understand how part geometry, material grade, press condition, die structure, tryout feedback and production volume work together. This is why Changdong places engineering review before manufacturing execution.
Changdong provides stamping die manufacturing services for custom sheet metal parts. Depending on the project, support may include process review, CAE analysis, 3D die design, machining, WEDM cutting, assembly, tryout and sample validation.
Used for high-volume strip-fed production where multiple cutting, forming and trimming operations are completed through sequential stations.
Suitable for larger or deeper parts that require station-to-station transfer, forming, trimming and restriking operations.
Applied to lower-volume, simple or staged production where one main operation is completed in each die.
Supports early sample validation, forming feasibility review and design improvement before full production tooling investment.
Changdong supports the main stages of stamping die production inside its own facility. In-house capability helps improve project communication, machining control, assembly coordination and tryout feedback.
| Manufacturing Stage | Purpose | Project Value |
|---|---|---|
| CNC Machining | Machining die plates, forming inserts, die bases and tooling structures | Supports dimensional accuracy and assembly fit |
| WEDM Cutting | Producing precision profiles, inserts, punches and cutting features | Helps control tight tooling profiles and cutting edges |
| Die Assembly | Fitting upper and lower die sections, guide systems and working components | Improves die alignment and tryout readiness |
| Tryout and Validation | Testing the die on press and checking stamped samples | Confirms forming quality, dimensions and production feasibility |
Changdong supports stamping die projects for automotive structural parts, chassis components, brackets, housings, appliance components, electrical parts and industrial stamped metal parts. Different parts require different tooling strategies, including progressive stamping, transfer stamping, drawing, bending, flanging, trimming and restriking.
Changdong operates with ISO 9001 and IATF 16949 quality management support. For stamping die projects, quality control is not limited to final inspection. It should run through engineering review, material planning, machining, assembly, tryout, sample inspection and final delivery.
Engineering review before tooling manufacturing begins.
Machining control for die plates, inserts, punches and working sections.
Assembly review for alignment, guide systems and die fitting.
Tryout feedback for forming defects, springback, burrs and dimensional variation.
Sample validation using dimensional inspection, CMM or checking fixtures when required.
Project evaluation begins with part geometry, material, tolerance, production volume and manufacturing feasibility.
Design, machining, WEDM cutting, assembly, tryout and validation can be connected within one project workflow.
Experience with progressive dies, transfer dies, structural parts, brackets, housings and complex sheet metal components.
Die tryout and sample validation help confirm forming stability, dimensional accuracy and tooling readiness.
