"Changdong provides in-house machining support for custom stamping dies and tooling components. Our machining capability supports die plates, inserts, punches, forming blocks, cutting components, stripper plates, guide components, and other custom parts used in progressive dies, transfer dies, tandem dies, and single-operation stamping tools.
With CNC machining, WEDM, drilling, grinding, and related machining processes, our team supports both new die manufacturing and tooling modification work. Keeping machining in-house helps improve communication between die design, machining, assembly, tryout, and inspection teams.
Key Points:
CNC machining for stamping die plates and tooling components
WEDM support for cutting profiles and die details
Machining support for inserts, punches, forming blocks, and cutting parts
In-house coordination with die assembly, tryout, and inspection
Support for new tooling, repair, and tooling modification projects"
Machining for Stamping Tooling
Stamping tool machining is the process of manufacturing die components according to the approved tool design. It includes machining die plates, inserts, punches, forming blocks, cavities, guide components, and other precision parts required for die assembly.
At Changdong, machining is closely connected with design, assembly, tryout, and inspection. This helps improve communication between departments, reduce outsourcing dependency, and support better control over tooling accuracy and project timing.
Machining Capabilities at Changdong
Changdong supports stamping die machining with CNC machining, wire EDM, precision grinding, and drilling equipment for die plates, inserts, punches, cavities, and custom tooling components.
CNC Machining
CNC machining is used for die plates, die bases, forming blocks, inserts, cavities, and large tooling structures. Changdong's CNC machining centers support both large stamping die components and smaller precision tooling parts according to approved die designs. CNC accuracy can reach 0.02 mm for 2D features and 0.05 mm for 3D surfaces.
Wire EDM
Wire EDM is used for precision profiles, punches, inserts, cutting edges, and complex die components that require accurate cutting. It is especially useful for sharp corners, tight profiles, and tooling details that are difficult to machine by conventional milling. WEDM accuracy can reach 0.01 mm.
Precision Grinding
Grinding helps improve flatness, thickness accuracy, surface finish, and fitting precision for die plates, inserts, punches, and other tooling components before assembly and tryout. Grinding accuracy can reach 0.005 mm.
Drilling
Drilling and hole processing are used for screw holes, dowel holes, mounting holes, positioning features, and structural details in stamping die plates and components. Changdong also uses high-speed CNC drilling equipment to improve hole processing efficiency for large die projects.
