It is suitable for applications that need to resist aggressive chemicals and high temperatures. These applications include aerospace and chemical processing.
Rubber metal bonding steps
Surface treatment
Metal surface: We clean and treat metal parts to make sure they have a clean and smooth surface. The metal surface can also be roughened in specific cases to enhance adhesion.
Rubber Surfaces: You can clean rubber surfaces and also use tackifiers or primers to treat them.
Application of Adhesives
Adhesives can bond metal, rubber, or both. The glue choice depends on the materials’ traits and their use.
During the bonding process, the metal surface first needs to be thoroughly cleaned. This removes all dirt and grease. This can be achieved by methods such as chemical cleaning or sand blasting. After cleaning, the metal surface must be dried using equipment to ensure that the adhesive can adhere effectively.
After cleaning and drying, apply the heat activated adhesive to the metal surface. This process can be done by spraying, brushing or dipping.
Throughout the process, care needs to be taken. The coating thickness of the adhesive needs to be strictly controlled to ensure consistency and optimal bonding.
Assembly
The rubber part is put on the metal part to make sure they align and touch. In some cases, heat is used to help the adhesive flow better into the rubber.
Curing or Vulcanisation
The bonded assembly goes through vulcanization to make the adhesive strong and create a strong bond. To complete the process, the assembly is heated and pressurized for a set amount of time. The type of adhesive and material being bonded determine the temperature and time parameters.
Quality inspection
The compliant material product must be inspected for bond strength and defects after bonding and curing. The inspection ensures that the quality meets the requirements.
Rubber-metal moulding method
Mechanical Nesting: This is a simple but effective method of interlocking rubber and metal surfaces. To achieve this, you can cover the metal part with rubber or cut and slot into the metal surface.
Adhesive bonding method: Rubber and metal are bonded together using a specific adhesive. To make sure the adhesive sticks well, treat the rubber and metal surfaces correctly.
Hot pressing method: The rubber and metal parts are put into hot moulds and pressed together to make a tight bond.
Vulcanisation method: Rubber and metal are put in a mould. They bond together when heated in a vulcanisation reaction.
Electroplating method: First, a conductive coating is applied to the metal surface. Then, rubber is deposited on the metal surface using an electrochemical process. This creates a smooth and even layer of rubber.
Mechanical insertion method:Insert the rubber part into the hole of the metal part, and fix the two together by mechanical means. This method works well for small parts like seals and vibration dampers.
