In the field of industrial buildings, the performance of the door sealing system directly affects energy efficiency and space protection capabilities. As the core component of the sealing system, the production technology of industrial door sealing strip has achieved a qualitative leap in recent years through material innovation and process upgrades. This article will deeply analyze its key technical links.
High Precision Extrusion Molding Process
The production of modern industrial door sealing strips generally adopts cold feed extrusion technology, and the stable molding of complex cross-sections is achieved through precision-designed special extruders and high-precision dies. This process breaks through the temperature control limitation of traditional method, maintains continuous and efficient production within the optimized temperature control range, and ensures that the density of the rubber material reaches the high standards of the industry. The real-time monitoring system is introduced during the molding process to ensure that the dimensional tolerance of the industrial door sealing strip strictly meets the requirements of precision manufacturing.
EPDM Modification Technology
The main material is made of high-quality EPDM. Through the scientifically proportioned reinforcement system and new stabilizers, the industrial door sealing strips still maintain excellent compression rebound performance under extreme temperature conditions. For special anti-corrosion needs, nano-level modified materials can be added in combination to significantly improve the acid and alkali resistance and meet the use requirements of harsh environments such as chemical and electroplating.
Multi-cavity Structure Design Optimization
The multi-cavity sealing structure developed based on the principle of fluid mechanics greatly improves the wind pressure resistance of the sealing system through the synergistic effect of different functional chambers. The main sealing lip adopts an inclined angle design that conforms to the mechanical properties, which can form an effective contact pressure within a reasonable compression range, and cooperates with the special surface treatment process to achieve multi-level sealing protection.
Breakthrough in Continuous Vulcanization Process
Adopting advanced continuous vulcanization production line, a uniform and stable vulcanization process is achieved in a high temperature environment. Compared with traditional processes, this technology significantly improves the strength and aging resistance of industrial door sealing strip. At the same time, it is equipped with an intelligent correction system to ensure that the linear accuracy of ultra-long size sealing strips meets engineering standards.
Energy Quality Control System
Establish a quality traceability system covering the entire process and set multi-dimensional monitoring nodes in key processes. Raw material composition detection and rubber performance control are carried out through precision instrument, and the finished product must undergo strict airtightness testing. Hengcheng Factory has obtained international quality management system certification and meets quality and environmental protection standards.
Upgrade Direction of Environmental Protection Process
The industry is accelerating the development of halogen-free flame retardant formulas, and adopting composite environmentally friendly flame retardant systems to improve the safety level of industrial door sealing strips. Simultaneously promote energy-saving pretreatment technology to effectively reduce production energy consumption and pollutant emissions, and respond to the development trend of green manufacturing.
With the rapid development of smart warehousing and clean workshop, industrial door sealing strips are evolving toward modularization and multifunctionality. In the future, Hengcheng manufacturing companies need to continue to strengthen innovation and research and development, combine digital technology to promote process upgrades, and provide more intelligent and reliable sealing solutions for industrial door systems.
