Helander – Enabling a Seamless Switchover from Metal Stamping

While metal stamping has been the conventional method of choice for metal forming, there is little doubt today that hydroforming is the definitive future of metal forming. Helander Metal Spinning Company provides hydroforming solutions that quite literally ‘stamp out’ all the drawbacks associated with the metal stamping process.

At Helander, we use a mix of hydroforming and metal spinning processes to produce structurally strong, tight tolerance components for industries such as: commercial food equipment, industrial machinery, industrial pumps, metal furniture, aerospace and defense, nuclear industry, HVAC industry and many more.

Hydroforming vs. Sheet Metal Stamping

Sheet Metal Stamping
Tooling costs
Set-up costs are high and often repetitive
One-time tooling costs
Production quantities
Often economically unfeasible for short runs or prototyping
Suitable and cost-effective for short, medium, and large production runs
Process costs

Costs for short runs are incredibly high, only dropping as the production quantity increases
Tooling,set-up, and development costs could be up to 80% lower
Finished product quality
Thinning or stretching could affect the desired tolerance and look of the component, making secondary finishing operations necessary
High quality of finished product reduces the need for secondary finishing operations. Parts also show better structural strength

Design changes are not easily possible once tooling has been created
Hydroforming offers higher versatility in regard to design changes
Material wastage
Even with close nesting, percentage of material wastage is high
Hydroforming produces very little or no scrap. Material wastage can go down by 50% to 70%
Lead times
Lead times are much longer, stretching up to several weeks for intricate part production
Surprisingly short lead times, even for large-scale production

Helandercustomarily works with OEMs and contract manufacturers. We alsopartner with metal stamping companies to honor their short productionrun requirements. To learn more about our capabilities, please visitour metalspinning and hydroformingpages.
