What is Metal Stamping, and how is it different from machining?

Metal Stamping, —also called “metal part pressing”—can produce identical metal components in larger volumes and in a short time. Stamping uses dies and powerful hydraulic stamping presses that apply tons of force to cold-form stock metal or “blanks” into tightly controlled shapes. The metal stamping process can involve using a progressive die with multiple stamping stages that cut, shape, and texture a metal blank to create final parts that consistently meet exacting part specifications.

Unlike machining that that cuts-way material to arrive at a desired form, Stamping molds shapes from existing material, so there is often much less wasted scrap. This can provide significant cost savings when stamping from expensive materials like stainless steel or titanium.

What are the primary advantages of stamping metal parts?

Production speed and cost savings are two advantages most commonly associated with creating parts through stamping.

Incorporating a high level of automation and computer-control precision, the stamping speeds we achieve at Ditron produce parts in less time — contributing to reduced expense. In some cases, this can include around-the-clock, “lights-out” production cycles. Costs savings also come through a reduction in material waste, and through the less-costly production and maintenance of stamping dies. Another plus: secondary finishing costs, including  cleaning and plating, tend to cost less.

How do I determine the best material for creating a stamped part?

Because of the extreme stamping pressure of our presses, most metals can be formed using a stamping process. Usually, material selection is determining by end part application needs.

For parts serving as an electrical contacts, Beryllium Copper treated to achieve a “C17200” rating” is used for its stiff tensile characteristics and superior electrical conductivity. For parts that “clip”  or require shape memory, Carbon Steels or Stainless Steels are often used because they provide repeatable “spring force.” Brass and Phosphor Bronze, both unplated and preplated, can also be used depending on durability and appearance requirements.

The best way to determine which material best suits your program needs to to call Ditron. We are ready to assist! (845) 227-9300.

What is the importance of base material thickness in stamping parts?

Determining the ideal thickness of the blank material is an important first step for checking immediate material availability. The thickness of different materials is referenced by “gauge” numbers unique to that material.

At Ditron, we have considerable experience stamping all type of metals is a variety of gauges. We understand how gauge will affect each material’s ability to bend, deflect and recoil without compromising structural integrity of the final part.

What is a “progressive” stamping die?

“Progressive Stamping Die” references an engineered series of press actions. With a progressive die, metal blanks are led through different sections of the die as it performs punching, cutting, bending, forming and more. This rapid, step-by-step stamping process results in completed part being made with a single pass through the press.

Is designing a progressive die necessary to manufacture a part?

Not always. However, if the part required is complex in dimension and shape, and if volume demands are high and ongoing, then designing, building, testing, and perfecting a progressive die can provide multiple advantages over the long run. These include production speed, predictability, and cost efficiency.

What factors can reduce cost of custom stamped metal parts?

The two biggest factors that affect price of Stamped Metal Parts are material selection and tolerance complexity.

Specialty materials and alloys often greatly increase stamped component cost. Ditron’s knowledge of material characteristics often results in suggestions of alternate materials that can provide specified performance and significant savings.

Specifying a custom thicknesses material can also add to cost. Ditron’s knowledge of how metals will react to forming requirements allows us to advise if a “standard thickness” option will work to meet all tolerances and specifications while saving you money.

Tolerance Complexity can also affect cost, because tight tolerances (with variation of ± 0.005” or less) require more complex operations, including increased tooling maintenance. Often, complex tolerance designs require secondary operations as well, further adding to end-part cost.

How do specified material tolerances affect stamping production?

Dimensional tolerances are used to provide accurate project quotes. Tighter tolerances reduce the speed in which a press can effectively stamp a part. The is in part due to how much distortion “recoil” the base material exhibits when being formed with each progressive stamping procedure.

What os RoHS Compliant and why is it important?

RoHS stands for “Restriction of Hazardous Substances” a directive initiated to help protect the environment through the monitoring of potentially dangerous raw materials used in electronic equipment.

The six substances deemed to be potentially harmful are lead, cadmium, mercury, hexavalent chromium, and polybrominated biphenyl (PBB). RoHS compliance in metal stamping ensures that materials used to make stamped parts have been certified to contain no or only trace amounts of these elements, at or below what have been internationally deemed to be safe thresholds.

What is JIT stamped part supply?

JIT stands for Just In Time. It references a responsive inventory-management program. With JIT, a supplier stands ready to Stamp, finish, package, and deliver specification-meeting parts according to a customer’s real-time and ongoing part supply demands.


New to Micro-Precision Metal Stamping? Here is the meaning to some Metal Stamping Terms used in the Stamping Industry and throughout the Ditron website.


Age Hardened: Subjecting metal to controlled heating in order to change its tensile propertied. In Metal Stamping, electrical parts made of Beryllium Copper Alloy are Age hardened in inert gas ovens to achieve C17200 Copper tensile properties.

Annealing: Heating metal to a temperature below its melting point, but high enough to alter the materials ductility. The metal is then cooled at a controlled rate that maintains modifies ductile properties so the metal is less brittle and more machinable.

Auxiliary Operations: Supplemental manufacturing actions like hole drilling, welding, electroplating, and coating that are not part of the pressure stamping process.


BDC: “Bottom Dead Center” — the lowest travel point of a stamping press stroke

Bending: A metal stamping procedure used to form parts like in simple V,U, or L shapes.
