Which Stamping Design Considerations Matter Before Tooling?

Which Stamping Design Considerations Matter Before Tooling?

Here’s something many program managers and purchasers don’t realize. The quality of a stamped metal part depends on just as much on the die as it does on the press. An expertly designed tool runs reliably for years. A poorly built one creates headaches with every run.

That’s why at Jordan Manufacturing handles die-design in house. Read on to discover the stamping design considerations our team evaluates for every project and how they lead to better parts. To learn how we put these principles into practice, speak to a member of our team about our capabilities and equipment.

Process-Focused Dimensions and Tolerances

Tolerances are one of the most important stamping design considerations since how a part is dimensioned not only influences tooling costs; it communicates nonnegotiable requirements to our die builders.

Punches, Pierced, and Blanked Features

A punched edge isn’t perfectly straight. The top portion shears cleanly, while the lower portion fractures and breaks away at a slight angle. Because of that taper, dimensions for these features should reference the sheared edge. For a hole or other inside feature, our team measures at the highest point of the shear. Outside features get measured at their widest point.

If your application can’t tolerate any taper, secondary operations such as shaving can create a straighter edge. This increases overall cost, so it is best reserved for features where edge quality makes a difference in part performance.

Formed Features

Bends introduce additional variables. As a rule, reference dimensions for formed features from the inside surface and account for bend variation when locating features beyond the bend. Each bend has some angular variation, often about one degree in either direction. The farther a hole or tab is from the bend line, the greater the effect on its final position. Tolerance should account for both variables.

Multiple bends add complexity because variation from each bend can accumulate quickly. Referencing critical features to a common datum helps control this stack-up.

Take a Practical Approach

Tight tolerance remains essential for features that affect fit or function. Allow more flexibility elsewhere to maintain part performance and reduce tooling construction and maintenance costs.

Account for Burrs and Edge Conditions

All punched edges have a burr side. Indicating burr direction on your drawing allows us to orient the part so sharp edges land where they cause the least trouble. Will people handle the part by hand? Does it mate against a seal? Note it in the design. Deburring techniques, like tumbling, can always be added, but knowing your application requirements upfront helps minimize overhead.

Simplify Geometry Wherever Possible

While complex geometries are not off limits, simpler is almost always more cost-effective. Sharp internal corners concentrate stress, which accelerates tooling wear, so add small radii wherever possible.

Deep draws may require several forming stages, and narrow tabs or thin webs can tear or buckle. Could a single format component replace a welded assembly? Could two parts become one? Questions like these can unlock significant, but substantial, cost savings.

Is Your HVAC Mounting Bracket Design Ready for High-Volume Stamping?

Is Your HVAC Mounting Bracket Design Ready for High-Volume Stamping?

Once an HVAC unit gets installed, its mounting brackets often don’t receive much attention, yet they play a major role in the reliability of the system. They need to be durable enough to support the weight of the unit under continuous vibration and withstand the elements.

For more than 75 years, Jordan Manufacturing has built and maintained die cutters and produced stamped, assembled components such as HVAC mounting brackets. Our years in business have taught us that the best brackets are not the thickest or the ones with complex geometries. They are engineered with the right balance of strength and material efficiency.

If you are about to launch a program and want insights from a tool expert, check out our guide below about designing stamped mounting brackets for HVAC equipment. Reach out to our Michigan headquarters to learn more about our capabilities and equipment or to get started.

Understanding the Load Requirements

Before sketching a flange, our team needs to understand the loads the bracket must support. Static weight is only one factor. Compressor cycling, fan startup, and wind exposure on wall- and roof-mounted units create additional dynamic forces. Our design accounts for these stresses to prevent cracking along the bend line.

Material Selection for HVAC Mounting Brackets

There are four core materials that Jordan Manufacturing uses to stamp HVAC mounting brackets. Mild steel is the cost-effective workhorse for most applications, especially when it’s covered with a protective coating. High-strength steel works better for heavier loads at thinner gauges. Stainless steel is well-suited for corrosive environments like coastal regions. Although aluminum is naturally resistant to corrosion, it is not often used for mounting brackets due to its lower load ratings.

Gauge is an important factor as well. A gauge that it is too heavy adds unnecessary cost to each assembly, but one that is too light can lead to fatigue failures. Rest assured, Jordan Manufacturing will work with you to find the right balance for your application.

Design Considerations for Critical Bracket Features

CAD models for HVAC mounting brackets don’t automatically translate a flawless final assembly. That is why we review every design with our customers before the tool gets made. Our focus is on key areas such as:

  • Bend radius: We often recommend an inside bend radius that is at least equal to the thickness of the material. If a design requires a tighter radius, we flag the cracking risk and collaborate with you on an alternative.
  • Hold placement: Holes too close to a bend line can stretch into an oval shape during forming. If we notice this in a client’s design, we recommend refining it so that the edge of each hole is at least 2.5 times the material thickness plus the bend radius away. If an application requires a hole closer than that, we can pierce it after forming.
  • Flange length: Extremely short flanges are difficult to form consistently, which is why we advise on a minimum of roughly four times the material thickness, adjusting the geometry if space is tight.
  • Bend relief: HVAC mounting bracket designs sometimes arrive at our facility without relief cuts where bends meet the edges. Small notches in those areas prevent tearing, so this is one of the first adjustments we usually propose.
  • Stiffness features: Clients will occasionally ask us about switching to a heavier gauge for more rigidity. Before going that route, we typically recommend embossed ribs or formed gussets to add strength without adding unnecessary material costs.

Build Better Brackets with Jordan Manufacturing

HVAC mounting brackets that provide years of reliable performance are born out of precision engineering and design collaboration. When engineers involve stamping specialists early in the development stage, it not only ensures the manufacturability of the brackets, but can also reduce overall project costs.

Mary Ellen Dohrs, Jordan Manufacturing, and the…Chicken Roaster?

Mary Ellen Dohrs, Jordan Manufacturing, and the…Chicken Roaster?

Visitors to Jordan Manufacturing’s office or booth at a tradeshow will find some interesting examples of our company’s current and past products. Each one is chosen to tell a story about Jordan Manufacturing’s place in American manufacturing history. One such product is the For the Birds Poultry Roasting Rack.

The Poultry Roasting Rack produced by Jordan Manufacturing in the early-90s has an interesting backstory. The idea and design was created by Mary Ellen Dohrs, an American industrial designer who did pioneering work for General Motors and Sundberg-Ferar.

Dohrs studied industrial design at the Pratt Institute in New York City and joined General Motors in 1950 at the age of 20. Not only was she the youngest designer working at any automaker, she was also one of the first female designers to work at GM, predating “The Damsels of Design” by several years.

At GM, Dohrs worked primarily on interior design, an area that had only recently gained importance in car styling. Her work combined elegance and practicality, seen in her interior design of the 1950 Series 62 Cadillac Convertible.

Mary Ellen believed car interiors should express both comfort and character, helping move automotive design beyond pure function.

After leaving GM, Dohrs continued her career with Sundberg-Ferar, where she contributed to industrial design projects for clients including IBM, Whirlpool, Samsonite, and Packard, for whom she designed the interior of the 1955 Caribbean.

In retirement, Mary Ellen continued to design and create art, later teaching art in school.

In 1986, a patent was filed with the USPTO for a “bird roasting assembly and method”. Mary had developed a rack that would allow cooks across the country to roast a chicken to perfection. “Tender goodness by gravity – not grease!”

Jordan Manufacturing’s founder, Robert Johnson, was related to Mary Ellen by marriage and helped design the forming and assembly fixtures. The roasters were manufactured in our facility in Belding, Michigan. The finished packaging included a book of recipes and a packet of spices. Robert took great pride in having helped a world-class designer bring her idea to life. Robert and Mary understood that art and inspiration are always connected to craft and technical skill. It’s always a pleasure to look at the item in my hand and learn about the mind from which it sprang.
