In the lighting industry, bending machines are widely used in the manufacturing of various lighting structural components, brackets, lampshades, and enclosures. Since lighting equipment requires high aesthetic standards and complex structures, many parts need precise bending to achieve both visual appeal and functionality. The types of components are diverse, and their tonnage and bending length requirements for bending machines vary accordingly. Below is a breakdown of common lighting components that require bending machines and their respective machine specifications.
1. Lighting Enclosures
The lighting enclosure is the main support structure of the lighting fixture, typically made of stainless steel, aluminum alloy, or cold-rolled steel, with a thickness of 1-2 mm. Bending machines are used to process these sheets into round, square, or irregular shapes to meet various lighting designs. Generally, 50-100 tons of bending force is sufficient, with bending lengths typically around 1-1.5 meters to fit various enclosure sizes. Aluminum is relatively easy to process due to its softness, but stainless steel may require a higher tonnage to ensure bending quality.
2. Lampshade Brackets
Lampshade brackets are used to fix and support the lampshade, ensuring its stability and safety. These brackets are usually made of steel or aluminum with a thickness of 1-1.5 mm. Although lampshade brackets are relatively small, they require high bending precision to ensure secure installation. Typically, 40-80 tons of bending force is sufficient for these parts, with a bending length of around 0.5-1 meter. Aluminum brackets are easier to shape, while thicker steel brackets may require slightly higher tonnage.
3. Installation Brackets and Hanging Structures
Installation brackets and hanging structures are used to mount lighting fixtures on walls or ceilings, ensuring long-term stability. These structures are usually made from 3 mm steel to enhance their load-bearing capacity. Depending on the size and thickness, they generally require 80-120 tons of bending force, with a bending length of 1-1.5 meters to accommodate different bracket sizes. Due to the weight and vibrations the structure must support, high-precision bending is crucial for safety.
4. Reflectors
Reflectors are essential components that concentrate light and enhance the lighting efficiency. They are typically made from stainless steel or aluminum sheets, with a thickness of around 0.5-1 mm. Reflectors often have complex designs requiring precise bending angles for optimal reflection. For these thin parts, 30-50 tons of bending force is usually sufficient, with bending lengths around 0.5-1 meter. Aluminum is easier to shape, while stainless steel may need slightly higher tonnage to ensure bending precision.
5. Decorative Frames and Trim
The decorative frames and trim of lighting fixtures enhance the product's appearance and structural integrity. These parts are usually made from 0.8-1 mm aluminum alloy or stainless steel and are essential for the fixture’s aesthetic appeal. Due to their thinness, 20-40 tons of bending force is adequate, with bending lengths typically between 0.5 and 1 meter. For unique shapes or higher precision requirements, CNC bending machines can be used to ensure accuracy in each bend angle.
6. Other Support and Internal Fixing Structures
In larger industrial lighting, additional support and internal fixing structures are necessary to secure internal electronic components. These structures are usually made from 2-3 mm steel to provide sufficient stability and load-bearing capacity. Depending on the size and thickness, 60-100 tons of bending force is typically required, with bending lengths based on the part's size, generally between 0.5 and 1.5 meters.
In summary, the lighting industry’s diverse processing needs require bending machines with tonnages ranging from 20 to 120 tons, with bending lengths adjusted according to specific parts. Manufacturers generally select bending machines based on product requirements to meet various processing demands. The right choice of bending machine not only improves production efficiency but also enhances product structure and appearance, providing safe, stable, and aesthetically pleasing lighting solutions for the industry.
