The valve is used for tire inflation and deflation, and is a core component of the tire. There’re snap-in valves (usually made of rubber) and clamp-in valves (usually made of metal). Now as the demand for TPMS is growing, TPMS valves have become a new engine for growth of the business.

Wheel weight is the core component for wheel dynamic balance. As a counterweight installed on the wheel, it ensures that the wheel remains a balance state under high-speed rotation. It can be divided into clip-on wheel weight and adhesive wheel weight according to the installation methods; steel wheel weight and zinc wheel weight according to materials.

Aluminum parts are an important product line of the company's lightweight strategy. Aluminum alloy materials have obvious advantages in improving transportation efficiency, recycling, energy conservation emission reduction, traffic safety and so on. Under the condition of maintaining the same quality, replacing steel with aluminum can reduce the weight of the vehicle by 30%-40%, which can not only improve the vehicle controllability, but also reduce fuel consumption. The application of aluminum products conforms to the lightweight trend of automotive.

Busbar (composite-structured connecting busbar) is used for the connection between the cells of the power battery, realizing the series/parallel structure of the cells, and it undertakes the sampling of voltage and temperature, which is very important to the safety of the power battery. It is widely used in electric and hybrid traction, electric traction equipment, cellular communication, base stations, telephone switching systems, large network equipment, large and medium-sized computers, power switching systems, welding systems, military equipment systems, power generation systems, power conversion modules of electric equipment, etc.

The air spring is an elastic component that uses the reaction force of the internal compression of the rubber airbag as the elasticity restoring force. As the core part of air suspension, it is widely used in passenger vehicles, buses, trucks and other heavy commercial vehicles. Proving more comfort and safety, air spring is the ideal replacement for traditional steel spring.
The air spring damper can adjust the damping force on different road surfaces through the lead type solenoid valve, and maintain the body posture during starting, steering and braking.

EGR pipes are technically mature and have very good performance. They can facilitate the in and out of exhaust gas when the EGR system is working and enhance the system’s efficiency. Exhaust gas recirculation system is a kind of off-machine purification technology, which reintroduces part of the exhaust gas from the engine into the cylinder for combustion, thereby reducing the temperature in the cylinder and NOx emissions.

With extensive product range, Baolong can provide customers with one-stop automotive sensor solutions. Baolong has developed and verified pressure sensors meeting China VI emission standard. With self-developed packaging design and packaging process techniques, our sensors are characterized by their high precision, wide measuring range, and wide application range, which provide technical foundations to accelerate auto intelligence and energy conservation.

Starting with the development of rain and light sensors in 2013, Baolong has built a strong, independent R&D team with rich experience. These sensors can detect rainfall to automatically control the wiper; detect the intensity of external ambient light to automatically control switching of lights; detect the intensity of sunlight radiation to adjust the temperature of A/C; detect the temperature and humidity of the inner side of the front windshield to automatically defog the windshield; detect the illuminance near HUD to automatically adjust the brightness of HUD. The newly-developed aerosol sensor is used in the battery management system of new energy vehicles to detect the concentration of aerosol in the battery pack by principles such as optical labyrinth design. These highly intelligent applications make driving safe, comfortable and easy.

Professional in developing, manufacturing and supplying speed sensors of high quality and high performance. Currently we have several speed sensors based on Hall, AMR, and GMR principles. Our speed sensors are critical to the electronic stability program (ESP), anti-lock braking system (ABS), control system of the automatic transmission, etc.

We have mastered technologies of 3D Hall, eddy current and TMR, and developed several sensors for essential systems such as chassis, steering and transmission. Our position sensors are critical to the brake-by-wire system (One Box), automated parking assist (APA), ADAS, suspension system, automatic headlight height adjustment, engine control system, control system of automatic transmission, etc.

The high-precision current sensors independently developed by Baolong have been applied by core systems of the vehicle. Crucial for the battery management system (BMS), battery distribution unit (BDU), and power distribution unit (PDU) of EV, power management equipment of industrial lithium battery and charging piles, current sensors can eliminate "range anxiety" and "charging anxiety" caused by excessive charging and discharging, effectively reduce accidents of new energy vehicles caused by batteries. Baolong’s current sensors have won recognition of many local OEMs and battery manufacturers.

Baolong’s accelerator sensors have been applied by the core systems of vehicles. They play important roles in the electronic stability program (ESP), active suspension system, internet of vehicles (TBOX), SRS system, etc., and can enhance comfort and safety.

With expertise in intelligent sensing and precise execution, Baolong provides highly reliable core components for embodied intelligent robots and low-altitude aircraft.
