Electronics Stamping Die

OP10 through OP60 can be checked and adjusted separately. This makes it easier to keep a correction at the operation where the dimensional change actually begins.

High-strength sheet requires attention to punch strength, bend recovery, local support and springback rather than treating the part like a thin terminal or shielding component.

Parts from different OP stages can be compared for hole position, profile, bend condition and surface changes before the final OP60 sample is approved.

Changdong's press capacity reaches 800T, with additional 400T, 260T, 160T and 45T presses available for different tooling programs.

If the OP60 part shows a shifted hole, flange or surface, that does not automatically mean OP60 caused it. The change may have started several operations earlier.

Keeping the six process samples together gives the engineering team a simple way to see when the part starts to move away from the expected geometry. This is particularly useful with DP600 because springback from an earlier forming operation can affect features produced later.

The released process drawing defines what each die actually does. The page does not assign unconfirmed forming, trimming or piercing functions to OP10–OP60. During tryout, inspection follows the real operation sequence instead.

Before later tools are adjusted, the OP10 part is checked for the features and geometry created by the first operation. An unstable starting part can make every following die look worse than it really is.

With a separate Electronics Stamping Die at OP10, the workpiece can be removed and inspected directly before it enters OP20.

If the OP10 part does not locate correctly in OP20, forcing it into position can hide the real problem. Incoming geometry and locator contact are checked before working areas are modified.

DP600 can retain residual stress after forming. A small amount of springback may change the way the part sits in the next die even when the earlier dimension looked acceptable immediately after stamping.

The OP20 and OP30 samples can be placed together to see what actually changed at this stage. Hole movement, local profile change, bend recovery or surface marking becomes easier to trace when the earlier part is still available.

If OP30 already shows a geometry problem, changing OP40 simply to make the part fit can create a second compensation. The better route is to identify what OP30 controls and correct it there whenever possible.

A dimension may pass on its own but still create interference in the final assembly. Hole relationship, formed surfaces and locating features can therefore be checked before the part reaches the final operation.

Before the part enters the final die, the important upstream geometry should already be understood. This keeps OP60 focused on the result assigned to it rather than correcting several earlier conditions at once.

If a scratch or tool mark is already present on the OP50 sample, the final die can be ruled out immediately. This is a simple but useful reason to keep operation samples during tryout.

The OP60 sample is checked against the drawing, but the earlier samples remain useful. If a hole, flange or profile is outside requirement, the six-stage sample sequence helps show whether OP60 owns the issue or only inherited it.

Depending on the drawing, inspection can include hole position, surface / profile, bend angle, trimming condition, burr direction, scratches and visible tool marks.

The completed part can also be checked against its assembly condition so that a dimension that passes individually does not create interference later.

Final OK samples are submitted only after the agreed dimensional and appearance items have passed inspection. The target for the finished sample is 100% against those agreed approval items.

Higher-strength sheet increases the load on pierced and trimmed features. Punch section, support and cutting clearance need to suit the actual feature instead of being copied from softer-sheet tooling.

Changing a locator does not solve springback. Where the part opens or moves after forming, the forming condition or restrike strategy needs to be reviewed at the operation responsible for the shape.

Frequently serviced punches and inserts are easier to maintain when they can be replaced without dismantling unrelated parts of the Electronics Stamping Die.

A six-die project creates many inserts, punches and precision profiles. Six WEDM machines allow several tool components to move through wire cutting without relying on one machine for the entire project.

CNC machining, including a 3-meter gantry machine, and high-speed drilling support die plates, structures and components required across several tools.

Changdong's in-house press line includes 800T, 400T, 260T, three 160T presses and one 45T press. Relevant presses can be matched to the actual die and process requirement.
