What kinds of lubricants are used in the injection molding machine?
Recently to see a lot of customers, with injection molding, stamping do, also do die, ask how the hydraulic oil inside the equipment they use, change a long oil ah, why to change the oil and so on, answer the baseThis is a dirty oil, water, use of time, and so on, we do not have time to change, for a few months, one year, two or three years, and the oil, that you have thought about these can be the cause of the oil?Here I would like to discuss the use of lubricating oil, lubricating oil scrap standards,Baidu search, it was posted that the deterioration of lubricating oil for the following reasons:1, lubricating oil is black (without detergent dispersant additives in lubricating oil).2, foam and emulsification has occurred.3, with fingers twist, the ground sticky feeling, hair acerbity or peculiar smell.4, drops on the white paper is dark brown, no yellow infiltration, slippery spots or black spots.thisIn fact, some problems can not be bad, because before there is not a good way to get him back, so we all think bad, more than 4 points, after all the following points, the first water emulsion,
No.Two, more impurities, especially the ultra small impurities, third, due to high temperature friction factors such as coke smell, currently on the market is not a good way to solve these micro impurities, water, emulsion, coke.So everyone thinks it's gone bad. It needs to be replaced. It's also for the maintenance of the equipment.Here, we will analyze the quality index of lubricating oil:1, viscosity: the most important point, in fact, this problem generally does not need to consider, almost all of the injection molding factory for oil viscosity is qualified, 5-8 years will not change.2, the impurity much, especially those of ultrafine particles of impurities, suspended in lubricating oil, lubricating oil to feel dirty, and more, this is a big problem, but it can solve, behind our discussion3, moisture: it is also a big problem, more than impurities, there are emulsified parts, there are free parts, discussed later4, partial acid: corrosion, sealing ring, etc., difficult to solve, but can be prevented, as long as the lubricant used to ensure that the temperature at ordinary temperatures below 50 degrees, there is no moisture, can be avoided4, pour point, freezing point, lightning: basic in injection molding die casting equipment such as oil, without too much consideration.5, additives: nothing more than anti-wear additives, antioxidants, anti foaming agents, anti emulsifier, etc., in general, additives will continue to wear and tear, but in general circumstances can be used for at least 5-8 years.Other seems to be nothing, and the above point of view, it is not difficult to analyze, as long as the removal of ultra-fine impurities, emulsification, moisture, oil can continue to use for 5-8 years.stay
Imported generally have thimble grease, the machine comes with lubricating oil bag
Centralized lubrication tank, we usually use the Haitian 00# advanced special grease, which will not thicken in the pipeline, the main and the next oil pump can work properly.
