What is four-slide side piercing?
Answer
Multi-slide production handles leaf springs, spring clips, brackets, collars, limiters, shunts, washers, connectors, friction pieces, solenoid housings, sensor housings, motor housings, retainers, and electrical terminals. It's especially valuable when multiple bends or side features would otherwise require separate operations and repeated part handling. How the tooling differs from a conventional press die Because the slides attack the workpiece from several directions, the tooling is mechanically more complex than a typical progressive die. Cam profiles, forming sequence, slide clearance, and part release all have to be coordinated precisely.

- Blanking vs Piercing vs Notching: What Is The DifferenceWhat is notching used for? Removing material from an edge or corner, usually to shape the outline of a part or to let a progressive strip index correctly. It produces neither a finished part nor a finished hole, which is why its tolerances are often specified more loosely. Do blanking, piercing and ...

What an engineer still needs from you
- material and material condition (grade, temper)
- material thickness, plus the key diameter, height and wall thickness
- tolerances, burr direction and the visual acceptance standard
- annual volume - it decides whether tooling is single-hit, progressive or transfer
- surface finish, and any secondary machining, annealing or plating
Need a DFM feasibility assessment for your project?
Send the engineering drawing (STEP or PDF) with the material grade, thickness and annual volume. Balford engineers then check it against the process window - draw ratio, wall thickness, tolerances, blank and tooling route - and come back with what is feasible and what is not. An answer on this page cannot replace that review.
