18. Completely automatic central lubrication system

The discussion about the necessity and the benefits of a central lubrication is constantly recurring.

The central lubrication of our machines extends far beyond the usual machine maintenance. For example, it lubricates all points that move in an automatic cycle when the machine is operating. All functions moved only when retooling are not lubricated. For instance, all cylinder heads of pneumatic cylinders are centrally lubricated. Especially the cylinder head gaskets are always poorly lubricated since the usual oiling via compressed air does not reach the cylinder head gaskets.

The linear guides of both heaters are also critical machine elements. They must not be neglected and are often barely accessible.

This option should always be chosen if there is no regular "lube maintenance team" in the company and if the machines are to be operated over more than one shift.

Also the drawback of the automatic lubrication should not be concealed. The automatic lubrication supplies all lube points with a predetermined amount of lubricant. This means that lubricant is permanently pumped into the machine. The result may be that the machine has to be cleaned once a year to remove any excess lubricant squeezed out. A permanently maintenance-free equipment of the machine is out of the question. For other reasons however it is also recommended to clean the machine because the fumes produced by thermoplastics also leave deposits on guides, bright spots, gaskets etc. These can definitely produce aggressive mixes, in particular when processing PVC. If a wide range of thermoplastics is processed it is obvious that regular cleaning offers many benefits.
