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.
