To achieve the sealing ring accuracy of 0.01mm, it is necessary to start from the design, material selection, manufacturing, testing and quality control and other links, the following is the specific approach:
First, design link
Accurate design: According to the use of the seal ring, working environment and pressure and other conditions, accurate design calculations to determine the size, shape and material of the seal ring.
Mold design: Design high-precision mold to ensure that the dimensional accuracy and shape accuracy of the mold meet the requirements. Mold manufacturing and assembly also need to be strictly controlled to avoid mold wear and deformation.
Second, material selection
High-quality materials: Select high-quality and stable rubber materials to ensure that the physical and chemical properties of the material meet the requirements of the sealing ring.
Material inspection: Strict inspection of raw materials, including physical properties, chemical properties and dimensional stability testing, to ensure that the quality of materials meet standards.
Third, manufacturing links
Advanced technology: The use of advanced manufacturing processes and equipment, such as precision injection molding, extrusion molding, etc., to ensure the manufacturing accuracy of the sealing ring.
Process control: In the manufacturing process, the process parameters such as temperature, pressure and time are strictly controlled to ensure the dimensional accuracy and performance of the sealing ring.
Environmental control: Keep the cleanliness of the production environment and temperature and humidity stability to prevent dust, oil and other impurities from polluting the seal ring.
Fourth, the detection link
High-precision measurement: Using high-precision measuring equipment and instruments, such as projectors, dial indicators, micrometers, etc., to accurately measure the dimensional accuracy of the sealing ring.
Full inspection or random inspection: according to the production batch and quantity, full inspection or random inspection is carried out to ensure that the dimensional accuracy of each seal ring meets the requirements.
Non-destructive testing: The use of non-destructive testing methods, such as machine vision measurement, non-destructive testing of the sealing ring to ensure the quality and performance of the sealing ring.
5. Quality control
Quality management system: Establish and implement a sound quality management system, including quality manuals, work instructions, process control procedures, etc., to ensure that each link is operated in accordance with the prescribed procedures and requirements.
Continuous improvement: Regularly evaluate and improve the production process and quality management system, adopt new technologies, new processes and new equipment, and constantly improve product quality and production efficiency.
Staff training: Conduct regular training and skill upgrading for production personnel to improve their operation level and quality awareness, and ensure that they can operate in strict accordance with the process requirements.
To sum up, in order to achieve the sealing ring accuracy of 0.01mm, it is necessary to start with multiple links such as design, material selection, manufacturing, testing and quality control, and take a series of measures to ensure the dimensional accuracy and performance of the sealing ring.
