Sheet Metal Bending Services in China
We offer sheet metal bending services from our production centers in China. Using CNC press brake machines,
we precisely bend sheet metal to create parts shaped exactly to your drawings. Our bending services in China
support clients around the world in industries like automotive, electronics, industrial machinery, medical
devices, and more.
Sheet metal bending helps transform flat metal sheets into useful shapes. It’s ideal for making brackets,
covers, enclosures, and various other structural components. We specialize in providing accurate, repeatable
bends, ensuring that your parts consistently meet your specific dimensions.
What Is Sheet Metal Bending?
Sheet metal bending is a manufacturing process used to shape flat metal sheets into angled or curved parts.
Using specialized machines called press brakes, metal is bent along straight lines into desired shapes or
angles. The process is also known as “forming.”
Press brakes use two main parts: a punch (top tool) and a die (bottom tool). The punch presses the metal
into the die to create an angle or curve. This method is efficient, precise, and suitable for small batches
as well as large production runs. Bending can be performed at various angles and multiple bends can form
complex shapes, all without welding or joining multiple pieces.
Our Bending Capabilities and Equipment
We utilize modern CNC (Computer Numerical Control) press brake machines. CNC technology provides
consistent, accurate bends across multiple parts, ensuring uniform quality throughout
production.
Our experienced technicians carefully program each job to match your design
requirements precisely, minimizing the chance of errors or inconsistencies. We perform detailed
inspections throughout the bending process to ensure every piece meets your specified dimensions and
angles.
Press Brake Specifications:
CNC-controlled for repeatable accuracy
- Press force: ranging from 50 tons up to 300 tons, allowing for both small precision components and larger structural parts
- Maximum bending length: up to 3,000 mm (3 meters)
- Bending tolerance: typically ±0.1 mm, depending on material thickness and length
Commonly Used Bending Techniques
Depending on your part’s specifications, we choose the method that achieves your desired accuracy and
performance.
We provide various bending methods based on your specific requirements:
Coining
Coining applies significant pressure to the metal, resulting in very sharp and clearly defined bends, often used when precise shapes and crisp edges are required.
Bottoming
Bottoming presses the metal firmly against the bottom of the die to form precise angles, useful for tight tolerances and specific angle requirements.
Air Bending
Air bending is common due to its flexibility. The punch presses the metal into the die, forming an angle without fully touching the bottom of the die. This method is ideal for a range of thicknesses and angles, providing good versatility.
Materials We Work With
Each material has specific properties affecting the bending process. Our experts adjust settings based
on the material’s thickness and hardness, ensuring that your parts maintain their structural integrity
and accuracy throughout production.
We can bend a wide range of sheet metal materials, including:
Aluminum and Aluminum Alloys
Galvanized Steel
Mild Steel
Copper
Brass
Stainless Steel
