Overview of metal-bonded rubber seals
Metal-bonded rubber seal is a composite sealing element that combines the rigidity of metal materials with the elasticity of rubber materials. It usually consists of two parts, a metal skeleton that provides strength and stability, and a rubber coating that provides excellent sealing and wear resistance. This composite structure enables metal-bonded rubber seals to maintain good sealing performance in harsh working environments such as high pressure, high temperature, and high wear, and are widely used in automobiles, machinery, chemical industry, aerospace and other fields.
The manufacturing process of metal-bonded rubber seals
The manufacturing process of metal-bonded rubber seals typically includes the following steps:
1. Preparation of metal skeletons
According to the design requirements of the seal, the appropriate metal material (such as stainless steel, aluminum alloy, etc.) is selected for processing to form the required skeleton shape. In this step, the dimensional accuracy and surface quality of the metal skeleton need to be tightly controlled to ensure the uniformity and adhesion of the subsequent rubber coating.
2. Selection and treatment of rubber materials
According to the temperature, pressure, medium and other conditions of the working environment, select appropriate rubber materials (such as silicone rubber, nitrile rubber, etc.). Rubber materials need to be pre-treated, including mixing, mixing, vulcanization, etc., to obtain the desired physical properties and chemical stability.
3. Bonding of metal and rubber
The pretreated rubber material is coated on the metal skeleton, and the rubber and metal are tightly combined through hot pressing, vulcanization and other processes. In this process, parameters such as temperature, pressure, and time need to be controlled to ensure a strong bond between the rubber and the metal.
4. Post-processing and inspection
Post-treatment of the manufactured metal-bonded rubber seals, such as grinding, cleaning, etc., to improve their appearance quality and sealing performance. Finally, quality inspection, including dimensional measurement, performance testing, etc., is carried out to ensure that the product meets the design requirements.
Performance characteristics of metal-bonded rubber seals
