SUS303 Multiple Bending with Parallelism 0.3

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.

Deposit Machine Component – Coin Slide Plate（SUS303、No Warping）

Deposit Machine Component – Coin Slide Plate（SUS303、No Warping） Precision sheet metal processing of coin slide components used in deposit machines. By controlling warpage in SUS303 processing, we achieve stable supply. Overview This case study showcases the manufacturing process of “coin slide component of deposit machines” delivered supplied to financial equipment manufacturers. To ensure reliable operation during coin insertion, strict standards were required for both flatness and parallelism. Initially, flatness variations of approximately 0.8–1.0mm occurred, but by optimizing material orientation and bending sequences, warping was eliminated, and a consistent flatness of 0.3mm was achieved. Features - Material: SUS303 (a hard stainless steel that is difficult to process) - Stable processing with flatness of 0.3 mm and no warpage - Component dimensions: 90 mm × 250 mm - Complex shape: 13 wave bends + 3 bends at each end - Supports mass production of 200 units/month - Shipping destination: Japan (deposit machine components) Technical Innovations - Changed bending start position to “center first” to minimize deformation - Optimized material grain direction to eliminate warpage - 100% inspection using a 3D measuring machine for quality assurance Industry Application Example - Financial equipment (ATMs, deposit machines) - Office equipment using precision mechanical components - Electronic equipment requiring high accuracy Even with SUS303, a material prone to warping and distortion, pursuing precision enables us to achieve stable supply to the Japanese market.
