SUS303 Multiple Bending with Parallelism 0.3

We achieved a parallelism of 0.3mm through multiple bending processes using the hard material SUS303. Our Vietnam facility ensures stable supply of high-precision sheet metal products.
Overview
This is a case example of bending in precision sheet metal processing. Using SUS303, a material that is difficult to process, we carried out complex forming that included 13 wave-like bends and multiple bends at both ends. To meet stringent accuracy requirements, we optimized processing steps and material orientation, achieving high precision with parallelism of 0.3 mm.
Features
Material: SUS303 (a hard stainless steel prone to warping)
Wave section: 13 bends; both ends: 3 bends each
Processing size: 90 mm × 250 mm
Flatness: within 0.3 mm
Equipment used: AMADA HG1003 Press Brake
Production volume: 200 units/month
Capabilities
Optimized grain direction of material to reduce the occurrence of warping.
Changed bending sequence from “ends first” to “center first” to minimize processing distortion
Conducted inspection using a 3D measuring machine to ensure stable dimensional accuracy
Applications
Financial equipment (deposit machines, ATMs)
Office equipment
Electronic equipment enclosures
Achieving both multiple bends and high precision with hard material SUS303 is made possible by the experience and ingenuity of LEO ELECTRONICS.
