EV Stamped Parts

The die markings visible in the project photos give a useful picture of the physical tooling behind this stamped component.

These figures are taken from the LW and UW markings shown on the photographed dies. They describe the actual upper- and lower-tool weights visible in this project rather than a generic tooling-capability range.

OP10 is visibly the heaviest set in the photographed group at approximately 2.14T, while OP50 is about 1.35T. We do not expect six tools in one production route to use identical structures.

Each operation has its own working area, support requirement, moving components and plate arrangement. The tool structure follows what that particular stage has to do rather than a standard weight target imposed across the project.

This is also why Changdong manages tooling cost and maintenance by actual OP instead of treating "six single-operation dies" as six copies of the same construction.

The exact stamping function assigned to each station follows the released process data; we do not infer an OP function from its number or external appearance alone.

For a stamped-parts customer, these tools are production assets behind the order rather than products that need to be purchased separately.

Changdong keeps the six dies together as one manufacturing program. Tool identification, maintenance history and changes to working components remain associated with the relevant OP so later production does not depend on workshop memory.

That becomes important over repeated orders. OP30 may receive maintenance while OP40 remains untouched; the production record needs to preserve that difference instead of recording only that "the tooling was serviced."

Changdong is not buying these six tools from another die supplier and then using them only as production equipment. We design and manufacture stamping dies ourselves.

If a production part begins to change, our stamping team can take the actual sample back to the toolmaking team. The relevant die can be opened, measured and corrected in the same facility.

Our Dongguan tooling operation includes 13 die design engineers, CNC machining, a 3-meter gantry CNC, six WEDM machines, EDM, grinding, high-speed drilling, die fitting and press tryout.

For customers sourcing EV Stamped Parts, this removes one supplier interface from the problem-solving loop. The company producing the component also has direct control of the tooling used to make it.

The three photographs together show the complete OP10–OP60 tooling group rather than isolated examples from unrelated projects.

For the customer, this means the supply program is backed by six identifiable production tools with known physical assets behind the finished component.

For Changdong, it means tooling condition becomes part of production planning. We know which die has been serviced, which tool is entering the next production run and which first-off sample needs additional attention after maintenance.

The customer orders stamped components, not six separate tool-maintenance projects.

Our job is to keep material, tooling, stamping and inspection coordinated so the part leaving OP60 continues to meet the agreed production requirement.

When tooling maintenance is required, we manage that work behind the supply program and verify the stamped result before regular production resumes.

This is the model Changdong uses for ongoing EV Stamped Parts supply: the dies remain our production assets, while the customer receives the approved component and the required production consistency.
