Harig Manufacturing Corporation is a precision metalworking technology company.

Founded in 1937 as a state-of-the-art tool and die builder, today we are a leading fineblanking and stamping supplier with strong tool and die support.

Harig pioneered the use of carbide dies and EDM and was one of the first companies to embrace fineblanking in 1965.

Today, with a staff of dedicated and skilled employees operating in a well equipped 55,000 sq. ft. plant, we produce precision parts for the automotive, appliance, power tool, aerospace, and controls industries - plus many others.

The World of Fineblanking and Stamping Under One Roof


We are large enough to provide full stamping and fineblanking services, yet small enough to give your part the personal attention it deserves. Our experience with fineblanking and conventional stamping allows us to find the optimal solution to your production needs. We believe our business model achieves high efficiency - producing high quality components while controlling costs.

We serve customers in many industries including automotive, appliance, power tools, hand tools, controls, and more. Now with third generation leadership, our company is poised to meet the challenges of the new millennium. Let us know how we can meet your needs.

The Fineblanking Process

The fine blanking process call for unique triple action presses and special fineblanking tooling.

Conventional stamping produces parts with sheared surfaces that are only partially (1/3) cleanly sheared, while the remaining portion (2/3) shows a rough break. When functional demands are made on these sheared/break surfaces, often the piece parts must be re-worked by shaving, milling, reaming, broaching, or grinding to improve tolerances and surface finishes.

The fineblanking process produces precise finished components with cleanly sheared surfaces over the whole material thickness in a single operation. Therefore, great production cost savings are realized, and payback time for the initial fineblanking investment is short.

Before the material is actually fineblanked, it is firmly clamped so that it can flow only in the cutting direction. Outside of the component cutting line, the material is sandwiched by the die and the v-ring plate (stinger). Clearance between punch and die is normally calculated at 1% of the material thickness to be worked.

The specific accuracy that can be achieved by fineblanking is largely dependent on:

Tolerance range is usually within one thousandth of an inch.
