Common questions people ask about metal stamping

Metal stamping is an art that has been around for hundreds of years. Today, this art has been modernized, but the key features remain the same. But even when you know this, you will require help in understanding what metal stamping is and how it happens.

This article answers some common questions people ask about metal stamping.

What is metal stamping?

One does not know that this $36 billion industry exists until you require metal stamping services. It is a process that cuts and shapes different types of metals into a finished product. Most metal objects you see today are the result of a metal stamping process.

You can make something as vast as a ship part or as intricate as a keyring with metal stamping. Once you have locked a design, you will get the most flawless finish with this manufacturing process. Other metal shaping processes are not as accurate as this; that is why people prefer metal stamping.

What are the types of metal stamping presses?

There are three types of presses involved in metal stamping,

Hydraulic press
Mechanical press
Mechanical servo

How many steps are included in metal stamping?

Like other production plants, metal stamping factories undergo some steps to complete an exceptional product. Here are some steps followed by professionals in the industry.

Planning

Detailed planning and blueprinting by engineers make sure that the product is just as the client requires. The planning phase may be as short as a week or as long as multiple weeks until a practical design is finalized.

Creating the die

The manufacturer creates a die before beginning the project. A die is a shaped tool that cuts the metal into the desired shape. Dies are valuable because they can be stored and used on the next project.

Cutting

Based on the company and client, cutting and assessment happen simultaneously.

Shaping

The final touches applied to every piece shape it into a high-quality product.

Are there different types of metal stamping?

Yes, there are a few types of the stamping process. Every product is not the same, so the manufacturers apply the most suitable kind of stamping method to your project.

Progressive stamping uses a systematic sequence of stamping steps. Each step complements the other, and cutting, bending, shaping happen at the same time. This is the fastest stamping method
Transfer die stamping separates the part and sends them to different stamping stations through conveyor belts. It is ideal for large parts.
Four-way stamping uses four sliding tools and shapes a product. It is suitable for products with a lot of crevices, grooves, and hinges.
Fine blanking smoothes out the edges of each part and gives them a high finish. It is usually done with a hydraulic press to apply a certain amount of pressure to the metal.

You can choose one type of stamping process, and finalize the assembly steps with the company engineers. It is always good to check your service provider’s record and client testimonials.

What are the commonly used parts of the assembly process?

Here are some main components used in the assembly process. Some parts differ based on company and method. For example, this metal stamping company running since 1961 uses the following parts:

Screws: Self-tapping screws, Machine screws

Welding: Arc Welding, TIG Welding, MIG Welding

Folding Techniques: Lap joint, Hem joint riveting

Press fitting: PEM inserts

What types of quality assurance processes happen?

Every company wishes to provide the best quality to their customers without hesitation. Overall, there should be no compromise based on quality. But, like all development processes, metal stamping also goes through a QA checkup.

Companies use random sampling and testing, which is based on statistical sampling. Random sampling ensures quality based on the size and weight of each metal sheet. Size is also proportional to the quantity required in one batch.

Part accuracy undergoes extensive checking before and at the end of each shift or product development.

How long does it take to come up with a sample part?

Typically, it takes up to two weeks to come up with the perfect sample. If the parts need to be re-modified, it will take more time. Production time also depends on the company, manufacturer, and type of metal used.

How do I choose the right process for metal stamping?

There such a wide variety of metal stamping processes that you may find confusing to pick one. Engineers focus on how complex it will be to produce your required part and the desired shape.
