This is the entire production process of the vulcanized rubber seal strip for the corner joint gaskets welding process. First, put the position where the two sections of rubber seal strips need to joint into the mold, and then move the mold to the corresponding position. When we are ready, we start the equipment and put the natural rubber on it. After heating, it melts and is injected into the mold through a small hole to form a whole part with our vulcanized rubber seal strips. There are standards for the grams of the natural rubber, including the melting and solidification time. You can use it after it is completely cooled and the strength of the joint is extremely high. Not only is the joint very strong, but it has a beautiful appearance, which also reflects its good weather resistance and long-lasting durability.
