Features & Advantages
Exceptional precision when every millimeter matters.
Each micro spring is manufactured under continuous digital magnification and optical sorting to ensure loop position and diameter are flawless.
Available with cleanroom processing, ultrasonic cleaning, and specialized materials like 316L stainless or implantable alloys.
Engineered to provide extremely sensitive and linear force progression for delicate switching and sensing mechanisms.
To prevent micro-hooks from interlinking during shipping, we utilize tacky boards, custom trays, or specialized tube packaging.
Micro Applications
