Which parts of the injection molding machine need to be refueled frequently?

Certain parts of an injection molding machine require frequent lubrication, including but not limited to the following:

1. Injection Unit (Screw): The injection unit of an injection molding machine melts the plastic and then pushes it into the mold via the screw. Therefore, frequent lubrication is required to maintain proper operation.

2. Gearbox: The drive motor of an injection molding machine is typically driven by a hydraulic motor or gearbox. These components require frequent lubrication to maintain proper operation.

3. Nozzle: The nozzle of an injection molding machine injects the molten plastic into the mold. Therefore, frequent lubrication is required to maintain proper operation.

4. Barrel: The barrel of an injection molding machine stores and heats the molten plastic. Frequent lubrication is also required to maintain proper operation.

It is important to note that each component of an injection molding machine requires different maintenance and care depending on its operating environment. Therefore, it is recommended that regular maintenance and care be performed according to the machine's instruction manual.
