Spherical rubber products should consider the wall thickness of the product and the hardness of the rubber when designing the mold, and pay attention to the sealing and bonding method at the interface of the semi-finished product. The mold structure and method have the primary molding method and the secondary molding method shown in the …
There is no significant difference between the injection molding formula and the molding formula. Most of the molding compound can be used for injection. However, since the injection method uses rapid temperature vulcanization, the rubber compound formulation should be adjusted. It is required that the Mooney viscosity before the injection of the rubber compound should …
The injection process is complex, affected by many factors, and has both process and mechanical equipment. They are connected and interact with each other. Several important process operating parameters of the injection process are introduced one by one. 1 temperature control The rubber injection process temperature control is to adjust the barrel temperature, injection temperature …
According to the relative position of the injection device and the clamping device, it can be divided into vertical and horizontal; according to the different transmission modes, it can be divided into hydraulic and mechanical; according to the number of working stations, it can be divided into single mode and multiple mode. The most common …
The production of rubber products by injection is generally carried out by several processes of preheating, plasticizing, injecting, vulcanizing and discharging. 1 Preheating, plasticizing The barrel heat is heated by the barrel heating and the screw rotation, and the rubber material sent to the barrel is heated. When the rubber is plasticized to a certain …
