Advanced Manufacturing Processes
We use pneumatic bending for consistent pressure application on medium-thickness sheets and laser angle measurement systems to control bending angles within ±0.2°. This ensures parts like stainless steel panels and aluminum brackets meet tight tolerance requirements in industries such as electronics and automotive.
One-Stop Service
We handle every step-from CAD drawing review, material selection (such as 304 stainless steel or 5052 aluminum), CNC cutting, bending, welding, surface finishing (like powder coating or anodizing), to final assembly and packaging. This reduces coordination efforts and shortens lead times for customers.
High-Quality Competitive Production Components
We produce components such as control boxes, heat sinks, and mounting frames in batch quantities using efficient nesting layouts and automated bending lines. This allows us to lower unit costs while maintaining stable quality, especially for repeat production orders.
Outstanding Timeliness
For each order, we define a production schedule, provide progress updates every 3–5 working days, and conduct final inspections within 24 hours of completion. For example, small batch orders under 500 pieces can typically be completed and shipped within 7–10 days.
Advantages of Our Bending Process
We use CNC press brakes with laser angle sensors to bend materials like 304 stainless steel and 5052 aluminum within ±0.2° tolerance. Automation improves consistency and shortens lead times-small batch orders can ship within 7 days. High-grade materials ensure the final parts, such as brackets and enclosures, meet mechanical strength and finish requirements for industrial use.
How bending process works
We use press brake technology to accurately bend sheet metal by calculating design parameters, aligning parts, and applying controlled force. This ensures precise angles for standard steel thicknesses, typically within ±0.2°. To meet diverse manufacturing needs, we also use rotary and roll bending machines for larger radii and complex shapes.
