Fine blanking is a cold extrusion process that uses special dies and presses to fabricate metal components that require exacting product features. The material is firmly clamped through V-grooves in the die and stripper plates, so that that the material may flow only in the cutting direction. Our highly skilled engineers study the product design and calculate the optimum blanking configuration. Press and tonnage requirements are determined through three forces: Cutting Force, Counter Force and V-Ring Force. Other factors that are considered include material specification and tensile strength, overall part geometry, material thickness and part function.

Typical Product Applications

Parts that require ultimate tensile strength, precision, extreme flatness, functional edges and possibly safety-critical lend themselves to the fine blanking process. Examples are as follows:

Powertrain: Automatic Transmission Parking Pawls Clutch Back Up Plates Thrust Spacers Valve Body Separator Plates Shift Forks Synchronizer Plates Valve Lifter Guides Oil Pump Covers Shift Detents		Seating Hardware: Latches Cams Gear Quadrants Lock Levers Latch Levers Engagement Pawls
Steering: Lock Nuts Trunion Washers Bulkhead Races		Other: Axle Flanges Consumer Speaker Backing Plates Door Detent Links Electronic Gears
