READ MOREIn the field of modern industry, oil seals are indispensable sealing elements in mechanical equipment, and their performance is directly related to the operating efficiency, stability and maintenance costs of the equipment. As a company with a strong R&D team and advanced manufacturing capabilities, we deeply understand the importance of oil seals in preventing leakage of oil, grease and other liquids, as well as the challenges of maintaining efficient and stable operation under different working conditions. We are not only committed to the design and material innovation of oil seals, but also pay special attention to the surface treatment technology of oil seals to ensure that their surface smoothness and wear resistance are optimal to meet the most demanding industrial application requirements.
Oil seal surface treatment methods
Electroplating technology:
Electroplating is one of the common methods to improve the surface hardness and corrosion resistance of oil seals. We use a precise electroplating process to plate a thin layer of metal (such as chromium, nickel, etc.) on the surface of the oil seal. This layer of metal can not only effectively resist the erosion of the external environment, but also significantly improve the hardness and wear resistance of the surface. . During the electroplating process, we strictly control the current density, plating time and plating solution composition to ensure that the coating is uniform, dense and firmly bonded to the substrate to avoid peeling or corrosion during use.
Spraying technology:
For specific application scenarios, we use high-performance spray materials (such as polytetrafluoroethylene PTFE, ceramic coatings, etc.) to spray the oil seal surface. These materials have extremely low friction coefficients, good high temperature resistance and chemical corrosion resistance, and can significantly improve the sealing effect and wear-resistant life of the oil seal. Before spraying, we perform strict pre-treatment on the oil seal surface, including cleaning, degreasing, roughening, etc., to ensure a good combination of the coating and the base material.
Chemical conversion coating treatment:
Chemical conversion coating is a dense compound film formed on the surface of the oil seal through chemical reaction, such as phosphate conversion coating, chromate conversion coating, etc. This treatment method can not only improve the corrosion resistance of the oil seal, but also improve the tribological properties of its surface to a certain extent. We use environmentally friendly chemical conversion agents and precisely control reaction conditions to generate a uniform and dense conversion film, which not only meets environmental protection requirements but also ensures the long-term stability of the oil seal.
Laser texturing:
In order to further optimize the sealing performance and wear resistance of the oil seal, we also introduced laser texturing technology. A laser beam is used to accurately carve tiny texture structures on the sealing lip of the oil seal. These textures can provide more sealing points and oil film retention capabilities without increasing frictional resistance, thereby improving the sealing effect. Laser texturing not only has high precision, but also enables customized designs to meet sealing needs under different working conditions.
Ensure the smoothness and wear resistance of the treated oil seal surface
High-precision processing and inspection:
In the entire process of oil seal production, we use the most advanced processing equipment and testing equipment in the industry to ensure that every step of the process meets extremely high precision requirements. Especially after the surface treatment is completed, we use high-precision surface roughness measuring instruments and profilometers to strictly inspect the oil seal surface to ensure that the surface smoothness meets the design requirements and reduce leakage and wear problems caused by surface defects.
Material and process matching verification:
Each surface treatment method and material has its own specific application scenarios and performance characteristics. In order to ensure that the processed oil seal can meet the actual needs of customers, we conducted a large number of material and process matching verifications during the research and development stage. By simulating friction, wear, corrosion and other tests under various working conditions, we continuously optimize surface treatment solutions to ensure that the final product has the best wear resistance, corrosion resistance and sealing performance.
Quality control system:
We have established a complete quality management system. From raw material procurement, production and processing to finished product inspection, every link strictly follows international quality standards such as ISO 9001. Especially in the surface treatment process, we have set up special quality control points to conduct regular testing and analysis of key raw materials such as electroplating solutions, spray materials, chemical conversion agents, etc. to ensure the consistency and stability of the treatment process.
Customized services:
In view of the differences in oil seal performance requirements of different customers, we provide comprehensive customer customization services. According to the specific needs of customers, we can adjust the surface treatment plan, including selecting different treatment processes, adjusting treatment parameters, etc., to ensure that the final product can fully meet customer expectations.
Our company has made remarkable achievements in oil seal surface treatment technology with its strong R&D team, advanced production equipment, complete testing methods and flexible customized service capabilities. We not only use a variety of advanced surface treatment methods, but also ensure that the treated oil seal has high surface smoothness and strong wear resistance through strict quality control and technological innovation, and can be widely used in automobiles, engineering machinery, agricultural machinery, and hydraulic equipment. , petrochemical industry and many other fields, especially under severe working conditions such as high temperature, high pressure, high speed and high load, it shows excellent sealing performance.
