In our use of grease, occasionally grease failure, this time our first reaction is to buy a poor quality products, in fact, not, the following small to tell you the reasons for grease failure.

1, high temperature impact

The increase of corrosive substances inside the grease, such as the acid formed in the work of injection molding machine.

The grease will oxidize and fail in the high temperature environment for a long time, and the phenomenon of blackening and thickening will occur.

The increase of carbon, grease sludge, varnish and other substances.

2、Failure of base grease

3, viscosity index enhancer failure because its organic molecules long forging break, no longer has a viscosity increasing effect.

4, additive failure some grease because of the additive failure or exhaustion and performance decline, for example, the anti-wear agent in the grease exhaustion, will make the anti-wear decline.

5、Impurities

Mainly from the dust in the air, metal abrasive particles, seepage, grease oxide and fuel combustion generated by the material.

The base grease is the carrier of the additive, the base grease failure, the additive will not play a role, although there are international standards to determine whether the injection molding machine grease replacement, but most of the grease replacement is mainly based on the injection molding machine and grease colour and viscosity to determine.

If the grease fails, it is not necessarily the grease that is the problem. It is likely that the grease will fail because of printing.
