Generally, the manufacturer has already assembled the machine, so when you receive the shipment, check that the package is not broken and that the machine is complete.
Read the instruction manual carefully, then follow the operating instructions to commission the machine.

What affects the quality of bending

Aluminum bending quality is affected by the following factors:

1. Bending angle: the bending angle is an important factor in determining the quality of aluminum plate bending. Too small or too large a bending angle and radius will lead to aluminum plate deformation, cracks, and other problems.
2. Type of aluminum: aluminum is divided into pure aluminum and aluminum alloy, and the hardness of aluminum alloy is affected by the addition of different materials. Too hard or thick materials require more force to be applied to complete the bend.
3. The quality and precision of the bending die: the quality and accuracy of the bending die greatly impact the quality of aluminum plate bending. The die's poor quality and low precision will easily lead to deformation, scratches, and other problems in the aluminum plate.
4. Machine stability and precision: this is also an important factor affecting the quality of aluminum plate bending. Poor machine stability and low precision will lead to deviations in the bending process of aluminum plates, affecting the bending quality.

In summary, the quality of aluminum plate bending is affected by a variety of factors, which need to be considered in the actual operation of these factors to ensure that the bending quality meets the requirements.

How to bend aluminum without destroying it?

1. Soften or anneal: Heat helps to anneal the material, making it softer and easier to bend. It also helps control the cracks you experience.
2. Choosing the right aluminum: Different types of aluminum have different hardnesses and toughnesses, and choosing the right one ensures that the bending process won't destroy it. Generally, softer aluminum is easier to bend without damaging it.
3. Choosing the right bending tool: the right bending tool can reduce the damage to the aluminum, such as a metal bending machine. In general, using a bending tool with a radius similar to the thickness of the aluminum can reduce the stress concentration on the aluminum.
4. Bending force: If you choose the traditional bending method, you need to apply force gradually during the bending process. And control the bending angle and strength to avoid sudden and excessive force that may cause aluminum to break.
5. Adopting appropriate bending methods: There are a variety of bending methods to choose from, such as V-bend, U-bend, folding, and so on. Choosing the appropriate bending method can reduce the damage to the aluminum.
6. Keep tools and materials clean: in the bending process, the aluminum and the tool's surface needs to be kept clean to avoid dirt and impurities on aluminum damage.

Generally, all grades of aluminum can be bent. However, different grades of aluminum have different hardnesses and toughnesses, so different measures need to be taken to avoid damaging the aluminum during the bending process.
Ideally, part designers should know that and will bend more easily for aluminum grades and will not.
Some high-strength aluminum alloys (e.g., 7xxx series) are more difficult to bend and require appropriate bending tools and methods and control of the bending angle and strength. Some soft aluminum alloys (such as the 1xxx series) are easier to bend.
Therefore, when bending aluminum plates, you need to select the appropriate aluminum and tools according to the specific grades and requirements. And master the correct operating techniques to ensure the bending quality meets the requirements.

Aluminum is a very popular metal for industrial use because of its light weight, strength and durability. Whether you&#;re a fabricator, engineer, or simply an industrial mechanics enthusiast, you&#;ll likely need to bend aluminum at one time or another to get the right parts for your project.

Bending aluminum can be a complex process that requires considerable expertise and experience to get accurate, quality results.

In this article, the experts at our industrial machining company walk you through different techniques for bending aluminum, as well as the benefits of each method.

Aluminum bending techniques

Metal bending, including aluminum bending, can be done in many different ways, depending on the specific needs of a project. Let&#;s look at some of the most common aluminum bending techniques.

1. Press brake

Press bending is a technique that uses a bending press to shape aluminum into a desired form. The bending press is equipped with a folding tool, also called a die, which is designed to bend the metal into a specific shape. The die is placed on the press, and the aluminum is placed underneath it. When the press is activated, the punch moves downward, bending the aluminum into the desired shape.

This technique is ideal for projects requiring right angles and simple shapes. It is also suitable for projects that require high volumes of production, as it allows for the efficient and rapid bending of large quantities of aluminum.

One of the advantages of press folding is its precision. Dies are made to exacting specifications, ensuring accurate and consistent results every time. Additionally, the press can be equipped with a bending force measurement system, which allows for the control for the pressure applied to the aluminum to avoid any deformation or damage.

2. Sheet metal bending

Sheet metal bending uses a machine called a &#;sheet metal brake&#; to bend sheet metal or aluminum into precise angles. The sheet metal brake is equipped with two parallel beams, also known as &#;bending edges,&#; that bend towards each other to form an angle and bend the desired material.

This technique is suitable for projects that require more complex angles and precise shapes, such as rounded or tapered shapes. It is also ideal for projects that require repetitive shapes, as the sheet metal brake can be programmed to repeat identical shapes on each cycle.

One of the advantages of sheet metal bending is its precision. Additionally, this technique can be used to bend large sheets of aluminum, making it an ideal option for projects requiring high volumes of production.

3. Coil rolling

Coil bending uses a machine called a &#;sheet metal roller,&#; which is equipped with a cylinder that rotates to bend aluminum into curved and circular shapes. The cylinder can be adjusted to create tighter or looser curves, and some models of sheet metal rollers are equipped with a measurement system to ensure optimal precision.

This technique is particularly relevant for projects requiring curved or circular shapes, such as round boxes or pipes. It is also optimal for projects involving repetitive shapes, as the sheet metal roller can be programmed by a conventional machinist to reproduce identical shapes on each cycle.

4. Rolling machine

The plate rolling technique uses a machine called a &#;rolling machine&#; that is equipped with two or three cylinders. The cylinders rotate at different speeds, allowing the aluminum to be bent into a cylindrical or conical shape. The rolling machines can be manual or automated, depending on the required production volume.

Like the previous technique, this method is suitable for projects requiring cylindrical or conical shapes, such as tubes, air ducts, chimneys, or tanks. It is also optimal for projects involving mass production.

Additionally, this technique can be used to bend aluminum sheets of different thicknesses, making it an ideal option for projects requiring varied dimensions.

5. Hand folding

Hand folding is an ancient technique that is often used for projects requiring a complex and unique shape that cannot be achieved with automated folding techniques. This technique is also ideal for projects requiring a low volume of production or unique pieces.

Hand folding requires considerable technical skill and experience to achieve accurate and high-quality results. Our machine maintenance experts are capable of accurately measuring the angles and dimensions of a piece, as well as handling the aluminum with care to avoid creases, cracks, or deformations.
