PROTOTYPE MATERIALS

Providing Deep Drawn Stampings, Brass Metal Stampings, Copper Stamping & Stainless Steel Stamping Services

Prototype & Short-Run Services, Inc. is an industry leader in short-run metal stampings. The process of short-run metal stamping involves the precision manufacturing of small numbers of punched metal parts. Quantities vary, but are generally less than 5,000 parts, and may even be as low ten parts.

Short-run metal stampings involve a combination of machines that are able to produce stampings to meet stringent requirements. Prototype & Short-Run Services uses this method most often for experimental, prototypes, and pilot lot production, especially when design changes are likely. Short-run metal stampings have shorter lead times, so they are ideal for faster delivery of seasonal products. Short-run metal stampings are also practical for specialty products when it’s not feasible to invest a large amount of money into permanent tooling.

Types of Metals

Prototype & Short-Run Services works with the following types of metal:

  • Stainless Steel
  • Brass
  • Aluminum
  • Copper
  • Galvanized Steel
  • Cold Rolled Steel
  • and more!

Deep Drawn Metal Stampings

Deep drawn stamping is a metal stamping process that converts flat sheet metal into three-dimensional shapes. Prototype & Short-Run Services, Inc. can convert stainless steel, brass, copper, aluminum, steel, nickel, and a variety of other metals into shapes such as cylinders, rectangles, and squares. A stamping press, consisting of a die and a punch, shapes the deep drawn parts. A part is considered “deep drawn” whenever the length or depth of the shape exceeds one-half of the part’s diameter. Prototype & Short-Run Services can create parts in different sizes and shapes, based on your designs.

Stainless Steel Stamping Capabilities

Prototype & Short-Run Services has been providing superior quality, custom stainless steel stampings for more than two decades. We specialize in deep drawn stainless steel components and prototype parts. Our high precision, perfectly repeatable production capabilities allow us to deliver complete-to-print parts in quantities to meet your demands and in quick turnaround times to fit your schedule.

We are a full-service metal stamping job shop with the capabilities to take your project from the concept and design stages to full production. We can provide design assistance and engineering, as needed, as well as a variety of finishing services (heat treating, deburring, etc.) to create stainless steel stampings that meet your unique requirements.

Deep Drawn Stainless Steel

In the deep-drawing process, sheet metal is formed into the desired part shape using a mechanical press and a series of progressive dies. First, the stainless steel sheet is “blanked,” or cut into round or shaped flats. From there, the blanks are then fed into a drawing machine, where a steel punch presses the metal into the dies in turn, with each one moving the material closer to the final shape of the part; resulting in seamless, one-piece metal parts.

Any holes the design may require are punched through the part after the drawing process. Excess material is trimmed after the part is finished.

Deep drawing is a “cold working” process. As the stainless steel is stretched and formed into part shapes, its grain structure is altered, and the material is work hardened. Deep drawn stainless steel parts have much greater physical strength than the original material from which it’s made.

Our deep drawing expertise enables us to produce both simple and complex stainless steel parts with incredible precision. More intricate part designs often require more steps/dies in the drawing process, but can ultimately be produced just as efficiently and effectively as basic designs.

Stainless Steel Grades

We can produce deep drawn stainless steel products and prototype parts in numerous grades, including, but not limited to:

  • 304 stainless steel
  • 305 stainless steel
  • 310 stainless steel
  • And Much More

Characteristics of Stainless Steel

Created by British metallurgist Harry Brearly in 1913, stainless steel is a steel alloy containing a minimum of 10.5% chromium content by mass. Other materials, such as nickel, niobium, and molybdenum may also be included. The material is ideal for applications where both the physical properties of steel and corrosion resistance are needed.

The addition of chromium helps the material resist corrosion from air and moisture that results in rusting (or “staining”) in standard low carbon steel. The chromium content naturally combines with atmospheric oxygen to form a microscopically thin—yet stable—layer of chromium oxide. This passive oxide layer prevents oxygen diffusion on the surface of the stainless steel and prohibits corrosion from spreading to the material’s internal structure.

If the chromium oxide layer is cut, scratched, or otherwise damaged, a new layer of oxide will rapidly form to cover the exposed area, protecting it from corrosion. Oxygen is required for this self-repair process; as such, stainless steel is considerably less effective in low-oxygen environments.

Benefits of Working with Stainless Steel

Deep drawn stainless steel parts are ideal for a wide range of applications. The material’s high corrosion resistance is its greatest and most desirable attribute; it also provides a distinctive appearance. Stainless steel can be steam-cleaned and sterilized, and requires no paint or other surface finishes, making it a very low maintenance material.

Prototype capabilities

Deep Drawn Brass

Deep drawing utilizes mechanical presses and a series of progressive brass dies to transform sheet metal into functional parts and components. Brass sheet is “blanked”—i.e. cut into round or shaped flat pieces—and these blanks are then fed into a stamping machine. A hydraulic-powered brass punch presses the blanks into specially designed and manufactured dies in sequence, gradually forming the material into the desired part shape. The end result is a seamless, one-piece metal part.

After the drawing process, any holes the part design requires are punched, and excess material is trimmed.

A beneficial side effect of deep drawing is work hardening of the material. As it is a “cold working” process, deep drawing alters the grain structure of the brass as it is stretched and formed into shape. This altered grain structure gives brass stampings greater physical strength than the unworked base material.

With our extensive experience, Prototype & Short-Run Services can manufacture brass parts, from the simplest to the most intricate, with unrivaled precision. In general, the more complex the part design, the more steps/dies the deep drawing process requires. However, parts of all kinds can be produced with comparable speed and accuracy.

Brass Grades

We work with brass in a range of grades to produce brass stampings as prototypes and long- and short-run production parts. Available brass grades include, but are not limited to:

  • Grade A brass
  • Grade B brass
  • Grade C brass
  • Etc. etc.

Characteristics of Brass

Brass is an alloy of copper and zinc that is used in a broad spectrum of applications. The proportions of the base metals can be varied considerably to create brass materials with varying properties; both very hard and very soft brasses are available. Compared to other structural materials, such as steel, it offers greater malleability but lower hardness. Brass is also tarnish resistant and can be polished to a mirror-like finish.

The relative softness of brass makes it ideal for use in flammable or explosive environments where sparks must be avoided. It is relatively low-friction, making it preferable for gears, bearings, locks, and valve components. It also possesses unique antimicrobial properties. Brass is commonly used for decorative components due to its gold-like appearance and high luster.

Benefits of Working with Brass

Deep drawn brass stampings are used in countless applications. In general, brass provides good strength and high corrosion resistance. It requires no painting or plating, making it a relatively low maintenance material. Plating is possible for certain applications.

Why Choose Aluminum for Your Deep Drawn Parts?

Deep drawn aluminum parts are popular for a broad spectrum of applications. The material offers a number of benefits that make it ideal for aerospace, medical, and everything in between.

  • Aluminum’s strength-to-weight ratio is perhaps its most desirable attribute, as it allows for very strong, yet lightweight, parts
     
  • Natural corrosion resistance makes aluminum a very low maintenance material
     
  • It offers outstanding durability in almost any application
     
  • Aluminum exhibits high electrical and thermal conductivity
     
  • The material is non-sparking, non-magnetic, and non-combustible

Aluminum Stampings vs. Steel Parts

Thanks to the material’s above-mentioned strength-to-weight ratio, aluminum stampings are commonly used to replace steel ones. Steel parts can be replaced with aluminum, significantly reducing the overall weight of the assembly or product (aluminum is roughly only a third as dense as carbon steel) with little to no loss of strength or durability. Other advantages of aluminum stamped parts over steel include:

  • Aluminum is more elastic and malleable than steel, making it easier to form into deeper and more intricate parts; aluminum, therefore, is ideal for the deep drawing process
     
  • With its natural corrosion resistance, aluminum stampings won’t rust like steel stampings will; no paint, coatings, or treatments are needed to protect aluminum against corrosion

The Deep Drawn Aluminum Stamping Process

Our aluminum stamping capabilities incorporate mechanical presses and progressive dies that form sheet metal into finished parts one step at a time. The aluminum sheet is “blanked”—i.e., cut into round or shaped flats—and then fed into the stamping machine. A hydraulic punch presses the material into a series of specially manufactured dies in sequence, gradually forming the material into the final part shape. Our precision stamping process results in seamless, one-piece metal parts.

After drawing, any holes your design may require are punched into the parts. Excess material is also trimmed away after drawing.

Because it is a “cold working” process, deep drawing has the beneficial side effect of work hardening the material. As the aluminum blanks are formed and stretched into their final shape, the grain structure of the metal is altered. This gives an aluminum stamping greater physical strength than the unworked material from which it originated.

Thanks to our precision stamping expertise, we can manufacture both simple and complex deep drawn aluminum parts with outstanding accuracy and repeatability. In general, more intricate parts require more steps/dies in the drawing process; however, Prototype & Short-Run Services can still produce them with the same speed and precision as basic part shapes.

Aluminum Grades

We can produce your aluminum prototype or production parts from a number of different aluminum grades. These include, but are not limited to:

  • 1100 aluminum
  • 2024 aluminum
  • 3003 aluminum
  • 5052 aluminum
  • 6061 aluminum
  • 6063 aluminum
  • 7075 aluminum

Characteristics of Aluminum

Aluminum is a silvery-white metal that makes up about 8% of the Earth’s solid surface, by weight. It offers strength comparable to carbon steel but at roughly one-third the density, giving it a favorable strength-to-weight ratio. Thanks to its naturally occurring, microscopically-thin, invisible oxide coating (aluminum oxide), it exhibits excellent corrosion resistance. Aluminum is very ductile and malleable, making it particularly well-suited to precision stamping processes.

Aluminum is non-magnetic, exceptionally durable, and has a relatively low melting point. It will not rust, has low spring back characteristics, and maintains superb dimensional stability.

The material does not require painting, plating, or coatings, but can be anodized to create a decorative finish and to improve its already excellent corrosion resistance.

Prototype Materials - Copper

Deep Drawn Copper

To create deep drawn parts, sheet copper is first “blanked,” or cut into round or shaped flats. From there, the flats are fed into the stamping machine, where a hydraulically-powered punch presses the material into shape via a series of progressive dies. As they move through the die sequence, the flats are gradually formed into the desired part shape. The deep drawing process results in seamless, one-piece parts.

Any holes that the part designs specify are punched into the part following the drawing process, and excess material is trimmed away.

Because deep drawing is a “cold working” process, the material is automatically work hardened. As the copper is stretched and formed into finished parts, the material’s grain structure is altered, giving it greater physical strength than the original base material.

Our experience and expertise enable us to produce any deep drawn copper part—from the simplest to the most complex—with exceptional precision. More intricate parts generally require more steps/dies in the stamping process, but can still be produced with the same speed and accuracy as more basic designs. And, deep drawn copper stamping is equally effective for prototype manufacturing and full production runs.

Copper Grades

We can produce deep drawn copper parts and prototypes in a wide range of material grades, including, but not limited to:

  • C11000 copper
  • C21000 copper
  • Copper alloys
  • Etc. etc.

Characteristics of Copper

Copper is a nonferrous metal, closely related to gold and silver and, like those metals, known for its distinctive color. It exhibits excellent thermal conductivity and electrical conductivity. It offers high tensile strength, high creep/deformation resistance, and a very low rate of thermal expansion. Copper is a relatively soft metal with excellent ductility, making it ideal for production via deep drawn stamping.

It is highly corrosion resistant, as it does not rust or otherwise react with water. Instead, copper reacts with atmospheric oxygen to produce a thin layer of copper oxide that protects the underlying material from corrosion.

The metal is naturally hygienic and exhibits antimicrobial properties, making it useful for applications in the medical and food and beverage industries. Copper’s color and ability to be polished to a high luster make it popular for decorative parts and components.

Along with zinc, copper is one of the base metals used to create brass.

Benefits of Working with Copper

Deep drawn copper parts are useful for myriad applications. The material’s unique physical properties make it popular for everything from electrical components to HVAC systems to architecture. Copper’s durability and resistance to corrosion make it an excellent, low maintenance material for part and prototype manufacturing.

Deep Drawn Galvanized Steel

Utilizing mechanical presses and specially-designed progressive dies, our galvanized steel stamping process transforms sheet metal into finished parts one step at a time. The steel sheet is “blanked”—cut into round or shaped flat pieces—and these blanks are fed into the stamping machine. A hydraulically-powered punch presses the steel into the dies in sequence, which gradually forms the material into the final part shape. Deep drawing produces seamless, one-piece parts.

After the drawing process is completed, any holes that your design requires are punched into the parts, and any excess material is trimmed away.

Deep drawing is a “cold working” process, which automatically work-hardens the material. As the galvanized steel is stretched and formed into its final shape, the metal’s grain structure is altered. This results in steel stampings with greater physical strength than the original base material.

With our experience and expertise, Prototype & Short-Run Services can manufacture any deep drawn galvanized steel part with unparalleled precision, from simple steel cylinders to highly complex specialty parts. Generally, the more intricate a part, the more steps/dies are required in the drawing process; we are capable of producing even the most complex components with the same speed and accuracy as simple designs.

Characteristics of Galvanized Steel

Steel is an alloy of iron and carbon that delivers high strength at low cost. Throughout the world, it is one of the most popular and commonly used construction materials; globally, over 1.3 billion tons of steel are produced annually. Steel provides greatly improved hardness and tensile strength over unalloyed iron. Other elements may be included in the steel alloy to improve other characteristics, such as hardenability or corrosion resistance.

Galvanized steel has been coated with a protective layer of zinc oxide to protect against corrosion. Galvanization protects steel by preventing corrosive substances from reaching the metal itself. A galvanized coating will also act as a “sacrificial layer”—if corrosion does take hold of the material, the zinc will corrode before the steel underneath is affected.

Galvanized steel also provides a distinctive, satin-like appearance that is popular for many applications.

Benefits of Working with Galvanized Steel

Deep drawn galvanized steel parts are used in countless applications. The material’s high strength, low cost, availability, and corrosion resistance characteristics make it popular for everything from building construction to sporting equipment. Galvanized steel is a highly durable, low maintenance material that is ideal for the deep drawing process.

Prototype Materials rolled steel

Deep Drawn Cold Rolled Steel

Manufacturing deep drawn parts is a multi-step process. First, sheet steel is “blanked,” or cut into round or shaped flats. These flats are then fed into one of our mechanical stamping presses, where hydraulically-powered punches press the material into a series of progressive dies specially made to produce your unique part. As the flats move through the die sequence, they are gradually formed into the final part shape. Our deep drawn stamping processes result in seamless, one-piece parts.

Any holes your design may require are punched into the parts after drawing, and any excess material is trimmed away.

Because it is a “cold working” process, deep drawing automatically work-hardens the material. As the steel blanks are formed and stretched into their final shape, the grain structure of the metal is altered. Cold rolled steel has already been strengthened by the cold rolling process, but the end result of deep drawing this material is steel parts with even greater physical strength.

With our stamping expertise, we can produce deep drawn cold rolled steel parts with exceptional precision and perfect repeatability, no matter how simple or intricate the designs. More complex designs generally require more steps/dies in the drawing process—at Prototype & Short-Run Services, we can produce intricate parts and components with the same speed and accuracy as more basic designs.

Characteristics of Cold Rolled Steel

Cold rolled steel is a type of steel that has been rolled or pressed into a thin-gauge sheet. The cold rolling process increases the strength of the material through strain hardening. Cold rolling can boost the strength of steel by as much as 20 percent or more, depending on the specifics of the process and the quality of the material.

Cold rolled steel exhibits many of the characteristics of untreated steel; It is lighter than standard steel but offers the same strength and stiffness. Cold rolled steel can be tempered during manufacturing to meet one of five standard hardness ratings, from Hard to Dead Soft; custom tempers can also be created. This material is less ductile than hot rolled steel, but its ductility can be partially restored through annealing or other heat treating processes.

In general, cold rolled steel is a soft gray color and has a smooth finish. A variety of surface treatments can be applied, including painting, plating, and specialty coatings.

Benefits of Working with Cold Rolled Steel

Cold rolled steel is used in a wide range of applications. It provides a favorable strength-to-weight ratio and excellent durability, making it ideal for parts and components used in building construction, automobile manufacturing, appliances, and more. It is easily workable via deep drawn stamping, making it easy to produce complex shapes with high precision.
