The Advantages and Disadvantages of Metal Stamping

Introduction

Discover metal stamping advantages, disadvantages, and techniques to ensure you select the correct metal stamping manufacturer for your business.

Growing at an expected CAGR of 4.7% between 2022 and 2030, the metal stamping industry continues to deliver quality products for an impressive array of businesses and industries.

However, knowing whether metal stamping solutions will provide your business with the ideal products requires a greater understanding. Let’s explore.

Discover metal stamping advantages, disadvantages, and techniques to ensure you select the correct metal stamping manufacturer for your business.

What is Metal Stamping?

Metal stamping is a metal fabrication and manufacturing process that uses indentation to form various shapes, letters and patterns onto sheet metal materials.

Also known as “pressing”, some common and complex metal forming techniques associated with metal stamping include the following:

  • Punching
  • Blanking
  • Embossing
  • Coining
  • Bending
  • Flanging

These metal stamping manufacturing processes and techniques are specifically selected and applied for specialist fabrication requirements across multiple industries and global markets, such as automotive, aerospace, and construction. 

The first attempts at metal stamping date back to the stamping of coins in the seventh century. Since metal stamping has continued to evolve and modernise with the times. The metal stamping industry now involves intricate and sophisticated technological advances, such as CNC (Computer-numerical control) and CAD (Computer-aided design) capabilities.  

How Does Metal Stamping Work?

The metal stamping process involves placing cold sheet metal into a machine known as a “stamping press” or “powder press”. A metal die gets applied with immense pressure to push into the material and form the desired shape.

After the initial stamping process is applied, the material can proceed to undergo further treatments, such as trimming, blanking, embossing, etc.

The metal stamping machine literally punches the shape from the surrounding material.

Typically followed by further processing, blanking involves cutting out the desired shape from the flat sheet metal material.

Also known as “Pewter work”, embossing involves creating raised and shallow features onto the material.

Coining involves indenting a pattern onto the material through compression. The name “coining” stems from the item metal stamping was first used to create.

Bending involves shaping the sheet metal in one direction. Often this process is repeated to create a specific shape.

Like bending, flanging involves moving the sheet metal in one direction but along a curved edge.

Typically followed by further processing, blanking involves cutting out the desired shape from the flat sheet metal material.

Metal Stamping Advantages and Disadvantages

So, now we have a core understanding of metal stamping and various processes, let’s take a look at the advantages and disadvantages.

The Advantages of Metal Stamping

When we consider the mass production of metal parts and products, accuracy and consistency are crucial to upkeep expectations while delivering quality to your consumer.

Due to the automation properties of CNC and CAD, metal stamping provides an efficient and accurate fabrication process to deliver precise parts for numerous purposes, including medical equipment and automotive components.

After establishing your die, automation means the stamping process becomes more cost-effective compared to other metal machining and fabrication techniques.

Automation means less time is needed for engineers and labour costs, while metal stamping can still form complex components quickly and accurately.

Plus, with no heating element involved, as you get with hot metal forging, metal stamping production provides a less expensive process for your manufacturing requirements. 

Through automation capabilities, metal stamping can help accelerate the manufacture and mass production of high-quality metal products, serving a healthy ROI (Return on investment) for business owners.

Top-quality metal stamping machinery is renowned for its speedy capabilities to deliver high production volumes, allowing companies to create and serve products to the market faster.

With metal folding, there are six main manufacturing techniques:

  • Air bending
  • Bottoming
  • Coining
  • Folding
  • Wiping bending
  • Rotary bending

Each metal folding method suits specific requirements and structural purposes.

Metal stamping offers incredible flexibility across an extensive range of products and industries. From intricate small parts to huge industrial components, the various processes available grant this metal fabrication process impressive flexibility.

Stamping allows manufacturers to be more creative with their designs and solutions. Whether you require complex brackets, clips or clamps, metal stamping can produce the lot across multiple materials.

Finally, it’s not just speed and flexibility. The underlying benefit of metal stamping is the high quality it produces thanks to the accuracy available.

This high-quality finish is proven by various applications across numerous industries that rely on metal stamping products for high-risk performance, such as medical equipment and aviation parts.

The Disadvantages of Metal Stamping

Metal presses are expensive pieces of machinery and are heavy and difficult to transport.

However, by hiring the services of pre-existing metal stamping manufacturer, you don’t have to worry about the metal stamping logistics as it’s already in place.

While custom dies can generate bespoke products and parts, the pre-production process can take longer if you require a tailored die to create specific shapes and designs.

How to Select a Metal Stamping Manufacturer

Before you choose a metal stamping manufacturer to produce your products and parts, you should always check their credentials and experience.

Whether you wish to hire specialists in a specific industry or those who perform on a global scale, check for authoritative certifications such as “ISO 9001 Accredited”, with a history of producing metal stamping products for other clients.
