Why is it important to maintain PET bottle blanks for injection moulds?

The maintenance of plastic bottle cap moulds is a useful measure to ensure the normal operation of the injection moulds. The maintenance of the equipment mainly includes finishing and wiping, inspection and adjustment, smooth and oiling, etc. The main points are as follows.
 

1. Stable product quality

To ensure that the plastic mould can produce qualified plastic parts stably and reliably, we need to make the PET injection mould in good working condition. When the injection mould is in operation, it may not always be in the best working condition. Always present this or that situation, such as guide pillar (guide pillar lubrication selected MFGrease VG CC series products), guide bush lack of oil caused by action block, fasteners loose cause action deformation, etc., these small problems, will bring bad product quality, and timely maintenance, will overcome these small problems so that the mold in good working condition.

2. Down the downtime maintenance moment

Bottle mould in the use of the process, there is always perhaps a larger fault and the need for downtime maintenance, in downtime can not continue to work, therefore, are expected to stop the moment the shorter the better, the less the number of downtimes the better. And the larger failure of the mold is often not suddenly presented, it has - a process of accumulation, such as sliding parts of the lack of oil will lead to increased wear, such as timely maintenance, timely refueling, pp injection blank mold will cut wear. So that the mold downtime delayed arrival, such as in the oblique column lateral core extraction mechanism, fixed oblique column of the screw onset of loosening, so that the position of the oblique column change, serious can make the oblique column deformation, and even broken, and in the maintenance will be the timely discovery of these problems, will be timely tightening, these similar problems will not occur.

3. Reduce running costs

Mold in the process of use, to pay many running costs, such as viewing costs, adjustment costs, smooth oil costs, repair costs, etc. The sum of these costs is the running costs. In these costs, the most quantity is the repair cost. If the mould is not well maintained, often have to pay a lot of extra repair costs, so that the mould can not work properly, and increase the operating costs. (Mould maintenance and repair: CORRO-001, CLEAN-201, CLEAN-303).

In addition to the basic maintenance of preform moulds, it is also important to note the problem of scaling in the mould waterway, which increases energy consumption and reduces efficiency.
