  • Nitinol spring

    The Nitinol spring is a versatile component, offering options for one-way or two-way configurations as well as tension or compression operations. Its adaptability extends to systems with irregular driving components. Furthermore, for applications demanding precision, the Active Af tolerance can reach ±1 ℃, ensuring accurate control in temperature-dependent scenarios.
