Vacuum Oil seal Rubber Molding Machine

A vacuum oil seal rubber molding machine is a specific type of rubber molding machine used to produce oil seals with the assistance of a vacuum. It utilizes the principles of vacuum technology to remove air and excess moisture from the mold cavity before the rubber material is injected.

The process begins with the mold being closed and the cavity being evacuated to create a vacuum. This helps in eliminating any trapped air or moisture that could lead to defects in the final oil seal. Once the vacuum is established, the rubber material, typically in the form of pellets or strips, is fed into the machine's injection unit.

The rubber material is then heated and plasticized in the injection unit before being injected into the mold cavity. The vacuum in the cavity ensures that the rubber material fills all the intricate details and corners of the mold, resulting in a high-precision and flawless oil seal.

After the rubber material has been injected, it is allowed to cool and solidify within the mold. Once the cooling process is completed, the mold is opened, and the newly formed oil seals are removed. These seals can then undergo additional processing steps if necessary, such as trimming excess flash or post-curing.

A vacuum oil seal rubber molding machine offers several advantages over traditional molding methods, including improved product quality, reduced waste, and increased production efficiency. The vacuum-assisted process helps in achieving consistent results by eliminating any gas or moisture-related issues during the molding process.
