As we use the injection moulding machine for a long time, we need to lubricate the joints to keep them working, but as time passes, the grease will always run out, so we need to purchase it.

Mechanical stability

In normal operation, the grease will be thrown from the bearing seat to the bearing. If the mechanical stability of the grease is not sufficient, the structure of the soap of the grease will be mechanically disintegrated during operation, causing the grease to be damaged and thus lose its lubricating effect.

Anti-rust performance

The injection moulding machine grease used in the bearing must have an anti-rust effect, the anti-rust agent is best insoluble in water, the injection moulding machine grease should have good adhesion and can form a layer of oil film on the steel surface.

Mixing injection moulding machine grease

Never mix incompatible injection moulding machine greases. If two incompatible injection moulding machine greases are mixed, the consistency will usually become softer and may end up causing damage to the bearing due to the easy loss of injection moulding machine grease. If you do not know which grease was originally used in the bearing, you must first thoroughly remove the old injection moulding machine grease inside and outside the bearing before adding new injection moulding machine grease.

Oil seals

The oil seal is a necessary barrier to protect the bearing and the lubricant from external contamination. During bearing operation, neither debris nor moisture can penetrate the bearing to prevent damage.

Important factors in choosing injection moulding machine grease

It is important to choose a grease that has a base oil viscosity that provides adequate lubrication at operating temperatures.

Some important factors in grease selection

The type of machinery, the type and size of the bearings, the operating temperature, the working load, the speed range, the operating conditions such as vibration and whether the spindle is oriented horizontally or vertically, the cooling conditions, the sealing effect and the peripheral environment.

Classification of injection moulding machine greases

The main distinction is based on temperature and working conditions: injection moulding machine greases can be classified according to their permissible working temperature. The consistency and lubricating capacity of injection moulding machine greases are influenced by the working temperature, and bearings operating at a certain temperature must be selected for injection moulding machine greases with the correct consistency and good lubricating effect at the same temperature.

It is therefore important to know the viscosity of the base oil at the operating temperature. Machine builders usually specify a certain injection moulding machine grease, however most standard greases are suitable for a wide range of applications.

The above is a share of the key points of purchasing injection moulding machine grease, if you want to know some other information about injection moulding machine grease, you can pay attention to Dongguan Yamaichi Lubricant Co.
