Metal Precision Fine Blanking Capabilities

Precision fine blanking is a specialized manufacturing process that produces parts with extremely tight tolerances and a clean edge, free of die breaks and tears on most materials, enhancing the aesthetic value of the part. The material’s precision cut edge is meticulously produced through a finely tuned metal stamping process that cannot be produced through conventional means.

At Petersen Precision, we provide fine blanking services that are engineered to your project’s precise specifications. Our precision fine blanking services, coupled with our value added secondary services eliminate the need for additional production processes such as reaming, broaching, edge grinding, countersinking, counter-boring, milling, and forming. Our precision secondary services also allow us to provide high volume part production capabilities.

For more information on precision fine blanking for custom parts, get in touch with our sales team or call us at 650-365-4373 and we will gladly speak with you regarding your project’s exact specifications. With more than 30 years' experience in fine blank stamping, Petersen Precision is your trusted industry expert.

Certified Fine Blanking Capabilities from Precision Metal Stamping Experts

Petersen Precision has the experience and the expertise to produce fine blanked parts that match your exact specifications. We operate out of an ISO 9001 Certified manufacturing facility and are uniquely equipped to take from the design stage through full production.

In House Tool & Die Shop

All fine blank stamping dies are designed, built, and serviced in-house to ensure superior precision and quality for your finished parts. Dies are serviced and maintained for the life of your program, whether you need ten thousand parts a year or a million.

Fine Blanking for Tight Tolerances & Extremely Accurate Parts

At Petersen Precision, we utilize the fine blanking process to achieve excellent dimensional control with consistent repeatability. Fineblanking allows us to produce accurately finished components with remarkable flatness, including inner and outer forms that are cleanly sheared to the precise specifications of your project. Some of the capabilities that precision fine blanking can reach includes:

• Tolerance capabilities better than +/-.0010” on feature location and size for the life of the program
• Creates 100% sheared edges with nearly 90° angles
• Dimensional accuracy akin to precision machining
• Coining and forming can be integrated into the process

Precision Repeatability & High Volume Production

High precision blanking is an extremely accurate way to produce parts with tolerances equal to or better than high-precision stamping or machining operations. Our fineblanking processes ensure precise repeatability from the first piece to the last, even for production runs with quantities in the millions.

Presses & Equipment for Fine Blanking

At Petersen Precision, we produce fine blanked parts on our 15 Feintool and Schmidt/Hydrel presses, ranging in weight from 40-250 tons.  We use both fixed punch and movable punch die designs in single station and progressive tools.  We design and fabricate our dies in house with a talented and experienced staff of journeyman toolmakers that are able to provide fineblanking tolerances of +/-.0005" (+/-13um).

High Volume Production Capabilities

Custom fineblanking services are highly regarded, providing quick, efficient, and accurate part productions of complex parts. If your project requires complex, small- to medium-sized metal parts in quantities of thousands to hundreds of thousands or more, fine blanking is the fastest, most efficient, and most cost-effective production method available.

Advantages of the Fineblanking Process

Metal fine blanking produces several intricate features in a single operation, with edge and surface finishes comparable to machining. Fine blank processing does not generate the severe roll-off and die break that conventional stamping operations produce. Fine blanked parts also maintain higher accuracy and better feature-to-feature tolerances in their profiles, holes, and other details than conventionally stamped parts. Additional benefits include:

• Superior edge quality, unsurpassed by any other stamping process
• Enhanced part flatness due to the counterpressure available through the cutting process
• Superb dimensional control, accuracy, and repeatability
• Reduced secondary finishing services due to precision die clearances
• Extremely economical for large production runs
• Multiple features can be added at once to maintain precision between features

Custom Fine Blanking Benefits

Perhaps the greatest benefit of fine blanking is that a single stroke of the press is all that is needed to produce a complete-to-print part or near-form blank. Fineblanking technology provides access to a variety of easily fabricated and consistent features including:

• Intricately shaped holes (i.e., not just circular holes)
• Slots and projections
• Coining or thinning
• Forming
• Shallow chamfers
• Semi-pierces
• Pockets
• Counterbores and countersinks
• Bends and offsets

Fine Blanking Material Options

Petersen Precision works with a wide variety of metals, in coil or strip form. All materials are stamped in an annealed state and can be hardened after stamping. We can produce your fineblanked parts from:

• 300 Series stainless steel
• 400 Series stainless steel
• Aluminum
• Cold rolled steel
• Copper
• Titanium
• Exotic Alloys

Fine Blanking vs Progressive Die Stamping

The fine blanking process produces die cut parts with squared edges by applying equal pressure to the top and bottom of a metal strip or coil. The resulting shearing action is akin to an extrusion which results in a part with smooth edges, a high degree of flatness, and tightly held dimensional tolerances. Parts designed for fineblanking may also require less finishing than conventionally stamped and machined parts.

Unlike progressive die stamping that utilizes multiple steps and workstations to complete the finishing service of a part, fineblanking provides advanced finishing services in a minimum number of steps. This ultimately saves a significant amount of time, providing significant cost savings for large scale productions.
