Laser cutting or automatic pressing? When should each process be used?

When it comes to metalworking, there are many methods to choose from, but two of the most common are laser cutting and automatic pressing, also known as stamping. Both have their unique advantages and are used in different contexts depending on the material, volume and design of the part. 

But how do you know which method is right for your project? Below we look at the differences, the benefits and when you should choose one over the other. 

How is laser cutting done? 

Laser cutting is a technique where a high-power laser melts or vaporises the material to create precise cuts. The process is digitally controlled, making it flexible and ideal for complex geometries and small production runs. 

Laser cutting is often used in industry for small batch production, parts with complex patterns or products where precision is crucial. What is classed as small series varies depending on the complexity of the parts to be manufactured. 

The advantages of it

• High precision and clean cuts, reducing the need for post-processing. 

• No contact with the material, so the material does not deform. 

• Flexible method suitable for both prototypes and small series. 

The disadvantages of it

• Costs more per unit of detail 

• Less effective for simple forms where faster methods can be used. 

• May require more follow-up processes such as bending 

What is automatic baling?

Automatic baling, or stamping, involves using a mould to press parts out of a metal sheet. It is ideal for mass production, where large quantities of identical components need to be produced quickly and cost-effectively. 

Advantages of the programme

• Very fast and efficient for large volumes. 

• Lower unit cost in mass production. 

• Can combine several steps in the same process, such as bending and embossing. 

Disadvantages

• Requires investment in moulds, which increases the initial cost. 

• Less flexible - design changes require new tools. 

Which method is best suited to your project?

So which method should you find a supplier for in your next project? The best answer is always: "check with the manufacturer offering the service process". There is only so much you can read into it and at the end of the day, an experienced designer will have a better answer and think of something that you are easily missing.  

To be somewhat familiar, these rough guidelines can help. Choose laser cutting if your parts require flexibility with design and you are 'testing' a product or if you are producing small batches to start with. Choose automatic pressing if you're producing large volumes and processing the material in multiple steps such as bending or embossing.
