Choice and Exchange of Lubricating Oil for Injection Molding Machine



One of the most common manufacturing equipment for polymer product is
injection molding machine. In order to ensure the precise, stable and continuous operation of the injection
molding machine, the maintenance of the lubrication system must be done well. The stability, reliability,
rationality and low noise performance of the lubrication system of injection molding machine
directly affect the quality of injection products, dimensional accuracy, molding cycle, working environment
and maintenance.



The purpose of this study is to introduce the methods of choice, maintenance of lubricating
oil for injection molding machine from many literatures and patents in the recent years, such as lubricating
oil device, lubricating composite and structure.



An example of the 260M5 automatic injection molding machine is introduced for the inspection
and maintenance of the lubrication system including lubricating oil and lubricating grease.



To ensure the lubrication of the injection molding machine, it needs to strictly observe the
lubrication time and modulus of the injection molding machine. It needs to strictly control the temperature
rise of the lubricating oil and select the correct lubricating oil and grease to ensure the lubrication
quality.



In the operation of the injection molding machine, it is necessary to check that the lubricating
oil is sufficient and the lubricating points are working properly. It ensures sufficient lubrication of
the injection molding machine and strictly observes the lubrication time and modulus of the injection
molding machine. The stored lubricating oil should be sealed well to prevent air pollution.
