How to maintain the preform mold daily

During the use of preform molds, there may always be major failures that require shutdown for maintenance, and the operation cannot continue during shutdown. Therefore, it is desirable that the shutdown time is as short as possible, and the number of shutdowns is as small as possible.

1. Ensure stable product quality

To ensure that the plastic mold can produce qualified plastic parts stably and reliably, it is necessary to keep the PET mold in good working condition. When the PET injection mold is working, it is impossible to always be in good working condition. There will always be one or another situation, such as the guide post (select MFGrease VG CC series products for guide post lubrication), the action block caused by the lack of oil in the guide sleeve, and the action deformation caused by loose fasteners, etc. These small problems will cause damage to the product Quality brings disadvantages, and timely maintenance will overcome these small defects and keep the mold in good working condition.

2. Keep descending and shut down for maintenance

During the use of preform molds, there may always be major failures that require shutdown for maintenance, and the operation cannot continue during shutdown. Therefore, it is desirable that the shutdown time is as short as possible, and the number of shutdowns is as small as possible. And the big fault of the mold often does not appear suddenly, it has a accumulation process, such as the lack of oil in the sliding part will lead to increased wear, if it can be maintained in time and refueled in time, the wear of the pp injection mold will be reduced. The stoppage of the mold is delayed, and for example, in the lateral core-pulling mechanism of the inclined guide post, the screw fixing the inclined guide post is loosened, which makes the position of the inclined guide post change, and in severe cases, the inclined guide post may be deformed or even broken. And these problems will be discovered in time during maintenance, and they will be fastened in time, and these similar problems will not happen.

3. Reduce operating costs

During the use of the mold, many operating costs have to be paid, such as inspection costs, adjustment costs, lubricating oil costs, repair costs, etc. The sum of these costs is the running cost. Among these costs, the largest amount is repair costs. If the mold is not well maintained, it is often necessary to pay a lot of extra repair costs, which will prevent the mold from working normally and increase the operating cost.
