You can boost your brand image by customizing your metal deliverables with a metal stamping press.

No matter what the application, you can order a custom metal stamp press to meet your unique needs. Today, there are extensive options available that will enable you to perform precise operations.

There’s a range of mechanical and hydraulic presses for operations of varying sizes. Read on to learn more about how metal stamping presses work.

What Is Metal Stamping?

With a metal stamping press, you can convert flat metal into specific shapes. Alternatively, you can use it for a number of metal forming processes, including blanking, bending, piercing and punching.

Around the world, manufacturers in fields such as automotive, aerospace, medical and other industries use metal stamping to produce goods. As the global market expands, the need to quickly deliver goods in significant quantities increases.

A metal stamp is fast and cost-effective. It’s ideal for mass manufacturing.

A metal stamp is also called a metal press or punch press. The metal pressing process encompasses placing flat sheet metal into a stamping press. In the press, a tool and die reshapes the metal to the desired form.

Before this takes place, however, engineers must design the tooling. They must produce precise designs that will ensure each punch and bend maintains proper clearance. This accuracy will ensure optimal quality.

A single 3D model can contain hundreds of parts. Because of this, it’s complex and time-consuming to engineer tools. Once the design stage is complete, however, a manufacturer can use a range of machining, grinding and other processes to complete production.

What Is a Metal Stamping Press?

There are several kinds of metal stamping presses.  For instance, there are hydraulic, servo, and pneumatic presses. Each type of stamping press gets its name from the drive that creates the force on the die that forms the stamp.

Within each category, there are two kinds of frame designs: straight-side and C-frame. Each of these frames may have a single-or double-slide ram connection.

A C-frame press has a shape like a C or G. Typically, workers operate a C frame press manually.

A low tonnage press can have a single-or double-ram connection. For manufacturers, this typically depends on whether the additional cost is worth a double-ram connection.

With mechanical presses, you can further separate them by their drives. For instance, a mechanical press may have a flywheel, single-gear or double-geared drive transmission that exerts force on the die. Other presses, such as a friction screw or hydroform press, are for special applications.

An electric motor that drives a large flywheel powers all metal presses. The flywheel stores kinetic energy. It then releases that energy through different kinds of drives.

The energy of the flywheel expands with each 360-degree cycle of the press. This cycle is called a stroke.

The flywheel will slow down 10% to 15% with each stroke. The electric motor will then restore that lost energy for the next cycle. If the slowdown, which operators measure in strokes per minute (SPM), is more than 15%, the electric motor cannot restore the lost energy.

In this instance, workers will have to stop and then restart the press using a clutch and brake that disengages the flywheel to the metal press drive. The clutch and brake are essential for the safety of the operator and the die.

Punch Press Techniques

Today, many punch presses have infinite stroke control. This feature enables the operator to adjust the ram stroke in increments of 0.00005-inches.

The ability to fine-tune the stroke improves accuracy. It also enables operators to make incremental adjustments to correct for variations in the thickness of materials.

Most newer punch machines also allow operators to control the ram upstroke. This ability allows an operator to program the upstroke to ensure that the press machine can clear any form.

It also enables operators to raise the tool to a height lower than top dead center. This feature improves speed and efficiency.

Upforming allows a punch press to make tall forms. In this process, engineers design spring-loaded strippers in the die assembly to create a tall die height.

Because of this extra height, the dies take up more room and in the turrent. The extra height reduces the space available for some metal forms.

In some instances, you can resolve this issue with an adjustable length punch holder. It will enable you to fine-tune forms. With older models, it may also allow you to use a broader range of tools.

You’re Only Limited by Your Imagination

Today, you can use a metal stamping press to create knockouts, extrusions, ribs, curved tabs and other shapes. These are only a small sampling of your available options.

Your choices are virtually unlimited with more modern metal stamping presses. All you need is a machine with the ability to create forms and a space for the machine. Engineers can design any tooling required for your project.
