1. Vibration-absorbing rubber


1). The role of shock-absorbing rubber: instead of metal springs, it can absorb and absorb vibration. Its main performance requirements are static stiffness, dynamic stiffness, and durability. Rubber injection molding machine can produce high-performance products.


2). Features of shock-absorbing rubber: (Compared with metal spring rubber)


① Rubber is a combination of multiple materials, and the same shape can have different properties through material adjustment.


②The friction between the internal molecules of the rubber gives it a certain damping performance, that is, the hysteresis of the movement (the deformation of the rubber lags behind the stress of the rubber during the force process).


③ Rubber will produce different elastic coefficients in the process of compression, shearing and stretching.


2. The working principle of shock-absorbing rubber:


① Vibration absorption: This kind of shock-absorbing rubber parts are mainly used for the connection between the engine and the body. In this state, the engine is the source of vibration. The function of the shock-absorbing rubber is to absorb the vibration generated by the engine and avoid transmission to the body. Reduce the vibration of the engine itself.


② Vibration reduction: This type of shock-absorbing rubber parts are mainly used for the connection between the chassis and the body. In this state, the chassis wheels are the source of vibration. The function of the shock-absorbing rubber is to quickly reduce the vibration generated by the road surface and the wheels through high damping. , To prevent vibration from being transmitted to the body through the chassis.


3. The basic process flow of shock-absorbing rubber


① Process flow of pure rubber products: ingredients, mixing, pre-forming, vulcanization, trimming, inspection, packaging, storage


② Process flow of skeleton products:


Ingredients Mixing Pre-forming


Degreasing the skeleton Derusting Phosphating Adhesive coating


Vulcanization, trimming, post-processing, inspection, packaging, storage
