Description

Technical Field

[0001] The present application relates to the technical field of inner tube production, and in particular to a simple inflation and shaping device for an inner tube before vulcanization. Background Art

[0002] Inner tube vulcanization is an important step in the tire manufacturing process. During the vulcanization process, the inner tube is placed in a mold and injected with a vulcanizer. It is then treated with high temperature and high pressure and shaped in the mold. The purpose of this step is to make the inner tube have good sealing and durability to prevent air leakage. If problems are found in the inner tube during the vulcanization process, such as the vulcanization nozzle, it may be due to insufficient vulcanization time or insufficient rubber content. At this time, it may be necessary to increase the vulcanization time or rubber content.
