Plastic products have a certain service life. Of course, plastic trays will do the same. Once they are used for a long time, they will gradually age. In order to prolong the service life of plastic trays, on the one hand, more work can be done on its preservation.
Plastic products have a certain service life. Of course, plastic trays will do the same. Once they are used for a long time, they will gradually age. In order to extend the service life of plastic trays, on the one hand, it can work harder on its preservation. In addition to being placed in a cool and dry place out of direct sunlight, it should be kept away from materials containing strong acids and alkalis.
If the plastic tray is not used for a while, you can apply some talcum powder on its appearance. This can also protect the plastic tray, thereby delaying its aging and extending the service life. In addition to the later maintenance, pay attention to the time of forming the plastic tray.
When plastic trays are molded, they usually go through a large pressure limit, because the cohesive force of the elastomer cannot be eliminated, so extremely unstable shortening often occurs when the mold is released from the mold, and it must be stable after a period of time. Therefore, when designing a plastic tray, whether it is a formula or a mold, it is necessary to calculate and cooperate carefully.
The raw materials for plastic trays are hot-melt and cold-set, so the molding and curing temperature is also required. Therefore, when making plastic trays, the temperature needs to be adjusted at any time to avoid affecting the molding quality of the product.
