Huizhou Pengchengrui Technology Co., Ltd.

The nickel titanium alloy spring core is super elastic, shape memory, and biocompatible, used for medical, aviation, automotive, electronic, and daily temperature control. It can automatically deform and reset under temperature triggering, or withstand large deformations without permanent damage.

1、 Medical (most mature)

• Vascular stent: After minimally invasive implantation, body temperature triggers dilation to support the blood vessels.

• Orthodontics: Orthodontic archwire with super elasticity, gentle and continuous force correction.

• Minimally invasive instruments: endoscopic clamps, biopsy forceps, orthopedic implants, with good elasticity and corrosion resistance.

• Implanted components: artificial heart valve, contraceptive device, with good biocompatibility.

2、 Aerospace

• Satellite deployment: solar panels, antennas, temperature triggered deployment after entering orbit.

• Aircraft shock absorption: landing gear, engine shock absorption, fatigue resistance, and extreme temperature resistance.

• Pipeline connection: fuel pipe adaptive joint, low-temperature assembly, high-temperature fastening.

3、 Automotive industry

• Temperature control valve: engine coolant, transmission oil circuit, temperature triggered switching.

• Battery safety: New energy vehicle battery pack buffering, thermal runaway protection.

• Suspension damping: Electronic control suspension, adaptive damping during bumps.

• Seat adjustment: memory spring, temperature/position adaptive.

4、 Consumer Electronics and Precision Machinery

• Folding screen hinge: Huawei Mate X5, etc., can be folded repeatedly without deformation.

• Wearable devices: eyeglass frames, watch straps, super elastic and not easily breakable.

• Micro switches/sensors: SIM holder for mobile phones, anti shake lens, precise reset.

5、 Daily and industrial temperature control

• Thermostatic valve core: shower faucet, water heater, automatically shuts off water to prevent scalding when the water temperature is too high.

• Home appliance temperature control: rice cooker pressure valve, air conditioning temperature control switch.

• Agricultural greenhouse: The skylight automatically opens for ventilation when the temperature rises.

• Industrial valves: for high temperature/corrosive environments, with automatic flow regulation.

Core Features

• Shape memory: Heat to restore the preset shape (adjustable from -50 ℃ to 150 ℃).

• Super elasticity: can recover strain up to 8%~10%, far superior to ordinary springs.

• Corrosion resistance: superior to stainless steel, suitable for body fluids and acid-base environments.

• Long lifespan: It can cycle up to a million times and has strong fatigue resistance.

Huizhou Pengchengrui can produce nickel titanium alloy springs with an inner diameter of 1.2mm, manufactured throughout the entire industry chain, and supports customization.
