Ultra-Thin Stainless Steel Precision Forming for Optical Applications
Project Overview
TM International supported the development of an ultra-thin stainless steel precision forming component used in a compact optical camera module application.
The project required extremely thin stainless steel material, stable narrow-width feeding, precision forming, and fine deburring to meet appearance and functional requirements for miniature optical assemblies.
Application
- Optical camera module component
- Retractable lens shading part
- Precision electronic / optical mechanism
Technical Challenges
Ultra-Thin Material Handling
The component utilized extremely thin stainless steel material down to:
0.05 mm SUS stainless steel
This thickness is thinner than standard paper and requires highly stable material control during feeding and forming.
Narrow-Width Feeding Stability
The material width was extremely narrow, requiring:
- Stable feeding tension control
- Precision progressive tooling alignment
- Anti-deformation process control
Burr & Surface Quality Control
Because the component is used in optical applications, the project required:
- Fine deburring
- Reduced particle generation
- Smooth edge condition
- Appearance-quality surface control
TM International applied precision vibratory finishing processes to improve edge smoothness and overall part quality.
