What Is Sheet Metal Forming?

Sheet Metal Forming Or Bending Is A Common Metalworking Technique That Uses External Force To Deform Flat Metal Sheets Into V, U, Or Groove Shapes. This Process Is More Cost-Effective Than Machining Or Casting From Solid Materials And More Stable Than Welding, As The Product Remains A Single Piece. Various Methods And Machines, Such As Press Brakes And Roll Benders, Are Used To Achieve Different Angles And Shapes.

Our bending process can completely produce complex shapes according to your design requirements, meet the needs of different products can also design a variety of bending angles and curves, improve the beauty and functionality of the product.

HIGH PROCESSING EFFICIENCY
Our bending machine can improve labor efficiency and simple operation after CNC programming. It can not only process continuously for 24 hours, but also quickly replace the bending mold in the bending machine. It is suitable for mass production of products in a short time, so as to improve production efficiency.

STRENGTHENING STRENGTH
Sheet metal bending strength compared with welding, bending strength is higher than welding, mainly reflects the strength of bending advantages are the following aspects: material rebound, bending Angle, local thickening, stress distribution, connection mode and so on.

SIMPLE FOLLOW-UP PROCESSING
The advantages of simple subsequent processing of sheet metal bending are mainly reflected in these aspects, 1 the convenience of welding can make the bending product produce better weld strength during welding. 2 High assembly efficiency, the bending product is usually combined with other products, usually the bending product will simplify the assembly process. 3 More flexible, if you need to fine-tune a part, only need to re-adjust a small part of the line.

FAQ

What are the common bending defects and how to solve them?

Crack: Select the appropriate bending radius and reduce the bending speed.
Deformation: Consider the elasticity and plasticity of the material in the design, and choose the bending order reasonably.
Asymmetric bending: to ensure that the fixture uniform force, avoid local excessive pressure.

How to control the elastic recovery of the material during bending?

During the bending process, the material undergoes elastic and plastic deformation. Elastic recovery is estimated by calculating “bending compensation” to ensure that the final Angle meets the design requirements. It is generally necessary to add 1-2° to the bending Angle as compensation.

What are the common metals for sheet metal bending?

Stainless steel: The commonly used stainless steel has 304, 316 and 430 and other grades.
Alloy steels such as A36, 1018 and 4140 are popular in metal bending due to their high tensile strength, durability, cost-effectiveness and versatility.
Aluminum material: Aluminum is malleable and easy to form different shapes and curvatures. It has excellent corrosion resistance and strength-to-weight ratio.
Copper: Copper is a soft material and the sheet is easily bent. However, careful handling and control of force is required to avoid surface damage or cracking.

What are the advantages of sheet metal bending?

The main advantage of bending is its ability to create complex parts without any seams. In addition, it is precise, cost-effective and versatile. It is capable of manufacturing rugged components for a variety of industries.
