As an indispensable part of modern industry, the quality of rubber seals directly affects the safety and stability of equipment and machinery. This article will introduce the manufacturing process of rubber sealing ring and its quality control measures in detail, to help readers deeply understand the production process and quality assurance measures of this key component.
1. Process manufacturing process
The manufacturing process of rubber seals consists of several key steps, and the precise execution of each step has an important impact on the quality of the final product.
Raw material selection and ratio: The first is to select the appropriate rubber raw materials, usually including nitrile butadiene rubber (NBR), acrylic rubber (ACM), fluorine rubber (FKM), etc., according to the specific use of the seal ring and the working environment to determine the appropriate ratio.
Mixing and extrusion: the selected proportion of rubber particles is mixed through the mixing machine to make it evenly mixed. Subsequently, the rubber material after mixing is extruded by an extruder to form the preliminary shape of the sealing ring.
Molding and vulcanization: The extruded rubber material is placed in the molding mold, formed by high temperature and pressure, and vulcanized to enhance its heat resistance and elasticity.
Post-treatment and inspection: Post-treatment of the vulcanized sealing ring, such as trimming corners, cleaning and coating with special lubricants. Finally, strict inspection, including appearance inspection, size measurement and functional performance testing, to ensure that the product meets the design requirements.
2. Quality control measures
In order to ensure the reliable and stable quality of rubber seals, the following quality control measures need to be strictly implemented during the manufacturing process:
Raw material quality control: strictly select high-quality rubber raw material suppliers, and carry out incoming raw material inspection to ensure that raw materials meet relevant standards and technical requirements.
Production process control: In the production process, strict process control and institutionalized operating procedures are implemented to ensure the accurate execution of each link and avoid quality problems caused by improper operation.
Product inspection and testing: Using advanced testing equipment and methods, the sealing ring after forming is comprehensively inspected, including appearance quality, dimensional accuracy, wear resistance, sealing performance and other aspects of the test to ensure the stability and reliability of the product.
Quality record and traceability: Establish a sound quality record and product traceability system, and record in detail the sealing rings produced in each batch, so as to facilitate the tracing and processing of abnormal products, and ensure the timely control and improvement of quality problems.
Through the detailed introduction of the above process manufacturing and quality control measures, readers can have a more comprehensive understanding of the manufacturing process of rubber seals and its quality assurance measures, provide reference and reference for practitioners in related industries, and further improve the quality and market competitiveness of seal products.
