Semi finished product manufacturing of oil seal production process: precision preformer is a semi-finished product manufacturing machine commonly used in foreign countries. It is characterized by accurate weight of semi-finished products, regular geometry switch, high production efficiency, rubber saving and high product qualification rate. It is also a necessary means to effectively realize high-temperature rapid molding and vulcanization process. There are also some seal ring oil seal manufacturers in China that introduce the equipment, but most oil seal manufacturers still use slitting machine and hand cutting semi-finished products.

High efficiency vulcanization process and equipment for oil seal production process: the development of oil seal vulcanization process and equipment is mainly high temperature (180-200 ℃ or higher), which can be vulcanized in a short time (1-2min). For these reasons, the automatic vacuum vulcanizer and injection machine are widely used, which makes the operation units mechanized and automatic, shortens the operation time, and improves the utilization rate of equipment and labor productivity.
