Fine Blanking Applications

Fine blanked automotive precision parts on dark background

Automotive Gears & Clutch Plates

Fine blanking replaces multi-operation machining on safety-critical automotive powertrain and body components. A transmission gear in 16MnCr5 case-hardening steel, 4 mm thick, that previously required blanking, drilling and gear shaving now comes off the press with 100% shear edge on the tooth profile, IT7 dimensional accuracy and die-roll below 15% of material thickness — eliminating gear shaving in most cases. Brake backing plates in HSLA, seat recliner mechanisms with ratchet teeth, and seatbelt anchor plates all benefit from the same single-stroke precision.

Lock Cylinders & Hardware

Lock cylinder production illustrates where fine blanking's cost advantage is most dramatic. A C45 steel lock cylinder plug conventionally requires bar stock, turning, drilling, milling and deburring — five operations with significant material waste. Fine blanking from coil stock produces the same geometry in a single stroke: clean sheared edges on all pin holes, consistent interlocking geometry across high-volume runs, and dimensional accuracy that eliminates reaming. The same applies to hinges, security hardware brackets and functional door hardware where tight hole-to-profile tolerances are non-negotiable.

Compressor & Motor Laminations

Rotor and stator laminations in electrical steel demand burr-free edges that maximize lamination stack density and minimize inter-lamination eddy current losses. Fine blanking produces these edges in a single stroke — no secondary deburring that could damage the insulation coating. Compressor valve plates benefit equally: 1.5 mm thick spring steel with 100% shear edge on the valve port profile, where any burr would prevent proper sealing and reduce compressor efficiency.

Electronics & Connector Terminals

Connector terminals in phosphor bronze and lead frames in copper alloy — fine blanking of thin conductive materials where the feed line, not the press, is the throughput bottleneck. A phosphor bronze connector terminal, 0.5 mm thick, requires burr-free edges that prevent insertion damage and ensure reliable contact. Fine blanking delivers this at production rates where progressive-die stamping leaves burr. Lead frames in copper alloy benefit from the same edge quality for wire bonding reliability.

Medical Device Components

Surgical instrument components in 316L stainless steel where burr tolerance can be a literal zero-tolerance callout — no micro-burr is acceptable on a part that contacts tissue. Fine blanking produces these parts with 100% shear edge, eliminating the vibratory deburring that can round critical cutting edges. Implant components and diagnostic equipment parts benefit from the same zero-burr capability, with project-specific process validation documenting every force parameter for traceability.

Agricultural & Industrial

Industrial clutch plates, agricultural machinery sprockets, e-bike transmission components and wiper system linkages — where the case for fine blanking is made on durability and total cost of ownership, not edge cosmetics. A hardened sprocket produced by fine blanking from 42CrMo4 steel achieves a tooth profile with 100% shear edge that resists wear without secondary machining. The same logic applies to excavator tooth plates, harvester blade carriers and mining equipment wear plates.

Material Range

Raw Materials & Processing

Fine blanking raw material steel coil and sheet stock

HS-FINEB presses process a full spectrum of engineering materials — low-carbon steel (C15-C60), high-strength low-alloy (HSLA) steel, case-hardening steel (16MnCr5, 20MnCr5), quenched and tempered steel (42CrMo4), stainless (304, 316L, 420), spring steel (65Mn, C67S), electrical steel, phosphor bronze, copper, brass and aluminum — at thicknesses from 1 mm to 25 mm depending on press model.

Material selection directly determines die design: V-ring geometry, blade clearance, counter-pressure and blanking speed all change with the material's shear strength, hardness and work-hardening behavior. Our engineering team reviews each customer's material grade and hardness specification during the quoting process to configure the press, die and feed line as a matched system — not three separate purchases.
