Product Info

Flat springs deliver precise, reliable force in compact electronics. Bangkok Sanyo Spring manufactures high-quality flat springs for battery contacts, EMI shielding, and tactile mechanisms using advanced materials and precision tooling.

What Are Flat Springs?
Flat springs are thin metal components engineered to bend and return to shape under load. Unlike coil springs, they deliver controlled force in limited spaces, ideal for compact and high-performance electronics.


■ Key Applications in Electronics:

- Battery Contacts: Maintain stable electrical connections
- Tactile Switches: Enable responsive user feedback
- EMI Shielding: Connect housings to ground circuits
- Internal Locks: Secure movable parts in small devices
- Optical Assemblies: Support precision alignment


■ Materials & Manufacturing:
Bangkok Sanyo Spring uses materials like SUS304, Phosphor Bronze, BeCu, and SK85 for durability and conductivity. Processes include:

- High-speed stamping with micron-level tolerance
- In-house die/tool design for accuracy
- Heat treatment and plating for longevity and performance


■ Design Considerations:
When selecting flat springs, evaluate:

- Spring force and load requirements
- Space constraints
- Fatigue life
- Electrical properties
- Environmental resistance
