Rubber and skeleton bonding method: Hard glue method, adhesive method, copper plating method and direct adhesion method. 1） Hard Adhesive Method This method is a hard rubber layer or a hard glue, which is used as a transition layer between rubber and metal to firmly bond the two. The method is applied for a long … Read moreRubber and metal bonding method and glue type
The metal skeleton degreasing method includes lye degreasing, solvent degreasing (dipping, washing, steam) and ultrasonic degreasing. The lye degreasing removes the oil on the surface of the metal by infiltration, dispersion, emulsification, and saponification of the oil by the lye. It is also a common method to impregnate or clean metal parts with a solvent … Read moreMetal skeleton degreasing method used in rubber
In order to ensure high adhesion between the skeleton and the rubber, the metal surface needs to be thoroughly cleaned to remove oil and rust, and a new surface is produced. Commonly used methods include chemical treatment (acid-base treatment), mechanical grinding or sand blasting, solvent treatment and copper plating. The solvent treatment method is inferior, … Read moreMetal skeleton surface treatment process
The metal skeleton of rubber products, whether cast iron, steel or aluminum alloy, must be treated before it is vulcanized with rubber. The reason is as follows. 1 When manufacturing metal skeletons, for the purpose of processing and anti-rust and anti-corrosion, the surface is often accompanied by a large amount of oil substances. These greases … Read moreWhy should the metal skeleton be surface treated?
The entire pressing process can be divided into the following steps 1 Place the molding die that meets the operation requirements in a flat vulcanizing machine and preheat for 10 to 20 minutes to the vulcanization temperature. 2 Pull the preheated mold from the flat vulcanizing machine (manually operated) or push out (mechanically operated) onto … Read moreFlat vulcanization process
