How are rubber bushings vulcanized

The production of rubber bushings requires multiple processes to complete. Among them, vulcanization is the most important process. So, how does the vulcanization process happen? Through this video, I believe you should have a more intuitive understanding.

Vulcanization is a process in which raw rubber is heated and combined with other materials to create a stronger, more resilient finished product. This process was invented in the early 19th century and has since been used to produce a variety of products, including tires, hoses, and gaskets. Vulcanization strengthens rubber by creating cross-links between its molecules. Rubber bushings are one of the many products that can be made using vulcanization. These components are commonly used in automotive applications to cushion and isolate suspension components from each other and from road vibrations. Vulcanizing rubber bushings improves their durability and resistance to heat and chemicals. As a result, they are able to withstand the rigors of everyday driving conditions better than unvulcanized rubber bushings. If you are considering replacing your vehicle's rubber bushings, look for ones that have been vulcanized for the best performance.

For example, for rubber bushing with inner and outer pipes, the first step is to put the processed pipe into mold. Generally, the production of bushings with inner and outer pipes requires two molds to hold the pipes separately. If it is a complex product , The corresponding structure of the mold will be more complicated. After that, the worker sets the time and temperature required for vulcanization on the control panel of the machine, and the machine will automatically start working. The formulated rubber will be fed into the machine from the feeding port. When encountering high temperatures, the rubber will becomes soft due to heating and is injected into the steel pipes to make them adhere.

When the vulcanization time on the control panel returns to 0, the vulcanization process is completed. After the machine cools down, the mold will be sent out, and the worker will take out the bushing from the mold, and then repeat this process to continue production. The vulcanization process takes a long time, and the speed of production is related to the number of mold cavities. The new automated machine can accommodate larger molds and have higher productivity, which greatly improves the production efficiency of rubber bushings.

Nanchang GJ Bushing Factory orders surge this year. The stability and high efficiency of the machine can ensure delivery time, so that customers can receive high-quality products within a satisfactory time.
