Industrial Sectional Door Industry knowledge

Industrial sectional door production equipment and process
In modern industrial production, industrial sectional doors are key facilities and are widely used in logistics, warehousing, manufacturing and other fields. In order to meet the market's growing demand for high-quality and high-efficiency products, Geajie Intelligent Equipment has carried out comprehensive technical upgrades and optimizations on the production equipment and processes of industrial sectional doors.
Fully automatic continuous production line
GEAJIE has introduced an advanced fully automatic continuous production line dedicated to the manufacture of industrial door panels. The implementation of this production line has significantly improved production efficiency and ensured product consistency and stability. The fully automated production process effectively reduces manual intervention and reduces the risk of human error, thereby improving the product's qualified rate and ensuring high customer satisfaction.
Automated control system
Our fully automatic production line is equipped with an advanced automated control system that can monitor key parameters such as temperature, pressure and speed in real time during the production process. Intelligent management methods not only improve production efficiency, but also respond quickly to emergencies to ensure the continuity and safety of production. The application of this system represents an important step in the transformation of industrial production to intelligence and digitalization.
Production line layout
The production line layout has been carefully designed and rationally partitioned according to the process flow to ensure efficient connection of each link. From the input, processing, assembly of raw materials to the output of finished products, the entire process is carried out in a closed environment, effectively avoiding the impact of the external environment on product quality. This optimized layout design promotes the improvement of production efficiency and reduces unnecessary time waste.
High-precision laser cutting technology
In the manufacturing process of industrial sectional doors, the cutting link is crucial. GEAJIE uses a high-precision laser cutting machine imported from Germany, which can accurately cut a variety of materials. The application of laser cutting technology ensures that the cutting accuracy reaches the millimeter level, significantly improves the utilization rate of materials, and ensures the rigor and aesthetics of the door structure.
Material adaptability
Our laser cutting machine has a wide range of material adaptability and can handle a variety of materials including steel, stainless steel and aluminum alloy. This diverse material selection enables our industrial sectional doors to meet the specific needs of different customers and show good market adaptability.
Fully automatic spraying and baking production line
In order to ensure the corrosion resistance and aesthetics of the surface of industrial sectional doors, GEAJIE introduced a fully automatic spraying and baking production line. The production line uses advanced spraying technology to achieve uniform and detailed spraying effects, ensuring the stable performance of the product in various environments.
Spraying process
During the spraying process, we use advanced electrostatic spraying technology to significantly improve the adhesion and uniformity of the coating. The coatings used have been strictly screened and have excellent weather resistance and UV resistance, ensuring that the product can still maintain good appearance and performance in a changing environment.
Baking process
After the spraying is completed, the product will enter the baking stage. High-temperature baking not only accelerates the curing process of the coating, but also improves the hardness and wear resistance of the coating. The baking temperature and time are precisely calculated to ensure the best coating effect, thereby extending the service life of the product.


Safety of industrial sectional door
In today's industrial environment, industrial sectional doors not only exist as entrances and exits, but also play a vital role in ensuring safety, improving efficiency and protecting assets. GEAJIE focuses on the research and development and production of high-quality industrial sectional doors, with special emphasis on product safety and reliability.
Safety of structural design
Application of high-strength materials
GEAJIE's industrial sectional doors are made of high-strength steel, stainless steel and aluminum alloy and other high-quality materials. These materials not only have excellent durability and impact resistance, but also can effectively resist external physical damage. The selection of high-strength materials enables the door body to withstand heavy impact and extreme weather conditions, thus ensuring safety in various complex environments.
Structural stability
The structural design after rigorous engineering calculation ensures the stability of the industrial sectional door during opening and closing. The segmented design of the door body allows each part to withstand pressure independently, thereby effectively reducing the stress concentration of the overall structure. This design concept significantly reduces the risk of deformation or breakage during use and improves the overall reliability of the product.
Intelligent safety function
Integration of safety sensors
GEAJIE's industrial sectional doors are equipped with a variety of advanced safety sensors, including photoelectric sensors and pressure sensors. These sensors can monitor the movement of the door body in real time to prevent people or objects from being clamped during the closing process. For example, when the sensor detects an obstacle, the door body will automatically stop or open in the opposite direction to ensure that the safety of people and goods is not threatened.
Anti-pinch function design
Our industrial sectional doors also have an anti-pinch device that can automatically detect any obstacles during the closing process of the door body and stop closing immediately. This function is particularly important in busy logistics and warehousing environments, effectively preventing accidental injuries caused by the closing of the door body and improving operational safety.
Operational safety
Advantages of user-friendly operation interface
GEAJIE's industrial sectional doors are equipped with an intuitive and easy-to-use operation interface, allowing users to easily master the operation mode, whether manual or automatic control. In addition, the operation interface is equipped with an emergency stop button, which is convenient for quickly stopping the operation of the door in an emergency, further ensuring the safety of personnel.
