Roll bending
Roll bending (or roll forming) uses strategically arranged rollers to gradually curve metal sheets or tubes, making it perfect for creating large radius bends such as structural components in telecommunication infrastructure.
Rotary draw bending
Primarily suitable for tubes and pipes, rotary draw bending precisely forms materials around a fixed die with internal mandrel support. This method ensures structural integrity and is widely applied in making piping systems for medical equipment.
V-bending and edge-bending
V-bending utilizes a punch and die to create simple, angular forms, frequently employed in sheet metal brackets. Edge bending forms small flanges, enhancing the rigidity and strength of products used in lighting solutions.
Several metals excel in metal bending due to their inherent ductility and mechanical properties:

Telecommunications
Metal bending produces durable telecommunication components like antenna mounts and protective housings, ensuring reliable performance in diverse environmental conditions and complementing the industry's demand for robust, weather-resistant materials.
Springback issues
Springback, where metal slightly reverts post-bending, poses challenges that fabricators manage by overbending or employing heat treatment processes to relieve internal stress.
Cracking and distortion
Cracking results from exceeding material limits, while distortion stems from incorrect tooling or techniques. Selecting appropriate materials and precise bending methods, often assisted by advanced simulation software, mitigates these risks effectively.
Maintaining tight tolerances
Maintaining stringent tolerances is critical for industries like aerospace or medical equipment manufacturing. Investing in high-quality, CNC-controlled bending equipment significantly enhances accuracy.
Strategies for prevention and correction
Employing precise machinery, appropriate tooling, software simulation, and routine quality checks collectively ensures the effective prevention and rectification of common bending problems, safeguarding product integrity and manufacturing efficiency.

This article delves into the process of custom metal bending, its advantages, and the industries that benefit from this technique.
What is Custom Metal Bending?
Custom metal bending refers to the process of using various mechanical methods to bend sheet metal into precise shapes and angles according to the specifications of a given design. The process is commonly used for producing parts that require specific curvatures, such as brackets, enclosures, channels, and frames.
The custom metal bending process typically involves the following steps:
- Design and Engineering: The first step is to develop a detailed design and blueprint of the part, taking into account factors like material type, thickness, and the required bend radius.
- Material Selection: Based on the design, an appropriate sheet metal material is selected. Common materials used for metal bending include steel, aluminum, brass, and stainless steel.
- Bending Process: The metal sheet is placed in a bending machine, where a die and punch system are used to bend the material at specific angles. Different techniques can be employed, such as air bending, bottoming, or coining, depending on the required results.
- Finishing and Inspection: After bending, the part may undergo further processes such as deburring, surface treatment, or coating. The final product is inspected for quality, ensuring that it meets the required dimensions and tolerances.

Bending sheet metal does not compromise the material’s strength. In fact, depending on the bending technique used, the part can be designed to have enhanced mechanical properties. For instance, parts that undergo “coining” or “bottoming” can have improved hardness along the bend area, making them more resistant to wear and stress.
- Benefit for Industrial Machinery: In machinery, custom metal bending ensures that parts like brackets and machine frames retain their strength and functionality, even when subjected to high stresses or heavy loads.
- Quick Turnaround Time
Because custom metal bending is a highly automated process, the lead times for production are generally shorter than other fabrication techniques. Once the design is finalized, parts can be bent, inspected, and delivered quickly, making it a great choice for projects that require fast prototyping or quick production timelines.
- Benefit for Prototyping: In industries that rely on rapid prototyping, such as product development and R&D, custom metal bending allows manufacturers to quickly create functional prototypes to test and refine designs.
Types of Custom Metal Bending Techniques
- Air Bending
Air bending is one of the most commonly used techniques in custom metal bending. In this process, the sheet metal is bent using a punch and die without the material touching the bottom of the die. The amount of bend is determined by the depth of the punch, and the angle is controlled by the CNC machine.
- Applications: Air bending is ideal for producing shallow bends on a wide range of materials and thicknesses, making it commonly used for parts like brackets and panels.
- Bottoming
Bottoming involves bending the sheet metal until it reaches the bottom of the die, resulting in a more precise angle. This technique is typically used for parts that require tight tolerances and accurate bending angles.
- Applications: Bottoming is used for parts like structural components, where high precision is required to ensure that the parts fit together correctly during assembly.
- Coining
Coining is a high-precision bending process where the punch and die apply force to the metal sheet until it reaches the desired angle. This technique is used to achieve very tight tolerances and is particularly useful for parts that need to be formed with minimal springback (the tendency of the material to return to its original shape).
- Applications: Coining is often used for high-precision applications like automotive brackets, frames, and electrical enclosures, where part accuracy is critical.
- Roll Bending
Roll bending involves passing the sheet metal through a set of rollers that gradually bend the material to the desired curvature. This technique is used for creating large-radius bends and cylindrical shapes.
- Applications: Roll bending is typically used for parts like tubes, pipes, and curved panels that require a continuous bend along their length.
