Understanding the Art of Metal Sheet Bending: Insights from a Top Supplier

When it comes to the fabrication of metal for a variety of applications - be it in construction, automotive, aerospace, or manufacturing - metal sheet bending holds vital importance. Our journey as a leading supplier in this domain has offered us ample insights that we are keen to share with you. Herein lies a narrative devoid of any formal conclusions, but rich with nuanced perspectives, shaped by decades of hands-on experience.

Metal Sheet Bending: A Concise Introduction

Metal sheet bending, at the core of its functionality, modifies the shape of sheet metals using stress. Via a combination of tension and compression forces, it alters the flat sheet into the required profile. The industry measures the angle of the bend, and the completion of the process, in degrees.

Bending Techniques – A Comparative Glance

A trio of methods prevail in the bending arena: Air Bending, Bottoming, and Coining.

Air Bending

As the least force-reliant of the three, Air Bending doesn't require the punch and die to touch during the process. This makes it advantageous for complex, precise bends with minimal tool marking. Although, it is noteworthy that the final bend angle is not solely dependent on the die angle due to spring back.

Bottoming (or Bottom Bending)

The Bottoming technique requires more force than Air Bending, because the sheet makes contact with the die during bending. Despite the higher tonnage needed, it provides a consistent angle, insensitive to material variations.

Coining

Requiring the most force, coining is more of a forming operation than a bending one. The upper tool forces into the bottom die to such an extent that the bend radius forms from the displacement of material around the tool*s radius. It ensures high accuracy with total control over spring back.

Customization of sheet metal processing services

We provide metal cutting and bending services to assist customers in sheet metal component processing. Automated cutting processes can ensure high precision and quality of finished components.

laser cutting

A cutting process that can be used to cut metal and non-metallic materials of different material thicknesses. The laser beam that has been guided, shaped, and assembled lays the foundation for this.

Metal punching

A common manufacturing process used to produce large quantities of metal components. It utilizes mechanical operations to shape metal sheets at high speeds through a stamping machine according to mold design trends, in order to achieve the desired shape and size.

Bending

It involves applying force to sheet metal parts to change their geometric shape. This force will generate stress on the metal plate that exceeds its yield strength, causing physical deformation of the material without rupture or failure.

Sheet Metal FAQs

During sheet metal processing, due to the characteristics of materials and processing methods, parts can deform. The solution is to adjust the processing technology and methods, strengthen the support and fixation of materials, and use automated processing equipment to solve the problem.

Welding quality issues in sheet metal processing may lead to issues such as insufficient component strength, porosity, and cracks. The solution is to use high-quality welding materials and equipment, strengthen monitoring and control of the welding process, and ensure that the welding quality meets the requirements.

After the sheet metal processing is completed, surface treatment is required, such as spraying, electroplating, etc. Poor surface treatment may lead to corrosion, oxidation, and other issues. The solution is to use appropriate surface treatment methods and equipment, strictly control the quality of the surface treatment process, and ensure that the surface treatment effect meets the requirements.

During sheet metal processing, dimensional deviations may result in parts being unable to be assembled or poorly assembled. The solution is to strengthen dimensional control and monitoring during the machining process, use high-precision equipment for machining, and compensate for dimensional errors during the machining process.

Quality issues may occur during sheet metal processing, such as surface burrs, cracks, pores, etc. The solution is to strengthen quality control and inspection, use advanced testing equipment and methods, and ensure that the quality of each product meets the requirements.
