Why should PET preform mold be maintained?

Maintenance of plastic bottle cap molds is an effective measure to ensure the normal operation of injection molds. The maintenance of equipment mainly includes cleaning and wiping, inspection and adjustment, smooth oiling, etc.

  Maintenance of plastic bottle cap molds is an effective measure to ensure the normal operation of injection molds. Maintenance of equipment mainly includes cleaning and wiping, inspection and adjustment, smooth oiling, etc. The main points are as follows.

  1. To 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 injection mold in good working condition. When the injection mold is working, it is impossible to always be in working condition. There will always be one or another situation, such as the guide post (for guide post lubrication, choose MFGrease VG CC series products), the lack of oil in the guide sleeve causes the action to be blocked, 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. Time for downtime and maintenance

   During the use of the preform mold, there may always be major failures that require shutdown for maintenance, and the operation cannot continue during the 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 an 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, a lot of 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 in 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. In addition to the basic maintenance of the preform mold, you should also pay attention to the fouling of the molded waterway, which will increase energy consumption and reduce efficiency.
