Production Process
1.Rubber Mixing
The core function of rubber mixing is to endow rubber materials with specific physical, chemical, and processing properties. This is achieved by uniformly mixing raw rubber with various compounding ingredients, thereby meeting the requirements of different industrial applications.
2.Banbury Mixing
The core function of Banbury Mixing lies in utilizing high shear force and pressure to achieve efficient and uniform blending of rubber with compounding ingredients. This process optimizes the physical properties, chemical stability, and processing performance of rubber materials, ultimately meeting the industrial production demands for consistent and reliable quality in rubber products.
3.Extruding
The role of extrusion in the inner tube production process is to transform the mixed rubber material into a continuous hollow tubular structure through mechanical pressure. This step provides the foundational shape for subsequent inner tube molding while ensuring material uniformity and enhancing production efficiency.
4.Ending Joint Valve Set
In the inner tube production process, the core function of the Ending Joint is to precisely connect the two ends of the extruded linear rubber cylinder, forming a closed ring structure. This step represents a critical transition from semi-finished product to finished inner tube.
5.Splcing
The core function of splicing is to precisely connect the two ends of the extruded linear rubber cylinder through mechanical or chemical methods to form a closed ring structure, ensuring the airtightness, structural integrity and production continuity of the inner tube.
6.Vulcanization
The core function of vulcanization is to transform unvulcanized linear rubber molecules into a three-dimensional cross-linked network structure through a chemical reaction under high-temperature and high-pressure conditions. This process endows the inner tube with critical properties-including strength, elasticity, durability, and airtightness-enabling it to withstand inflation pressures, road-induced impacts, and prolonged service without failure.
7.Quality Control
Quality Control (QC) serves as the cornerstone throughout the entire inner tube production process. Its primary role is to ensure compliance with design specifications in dimensional accuracy, physical properties, airtightness, and surface consistency through systematic testing protocols, standardized operational procedures, and data-driven continuous improvement initiatives. This comprehensive approach effectively reduces scrap rates, enhances production efficiency, and guarantees end-user safety.
