Many manufacturers are concerned about the quality of Pet Bottle Preform, but they neglect to maintain molds is also a very important process, closely related to mold life. Now I will show you how to maintain the mold under normal conditions. The first is mold maintenance in mold assembly. Before the mold is assembled, you need to clean the mold first to ensure that the mold surface is not crushed and level. After the mold is assembled, you need to open the mold and clean all parts of the mold, especially the cavity and core surface to ensure the quality of the plastic product. Then lubricate each sliding part of the mold and check the mold again, especially the safety parts such as safety side pins, screws, side guards, etc. The second is to maintain the mold during the production process. Before you can use it to make a product, you need to make sure that the mold has no residual plastic. Because the plastic may break the mold surface when the mold is clamped. You need to lubricate the mold regularly to ensure that the mold is in good condition. The third is mold maintenance after the production line. After the production is complete, you need to thoroughly inspect the mold, thoroughly clean the mold, and remove all water and plastic from the mold. There are a lot of plastic molds for you to choose from, and also provide a series of follow-up after-sales services to help you with the daily maintenance of molds and equipment. The 5-gallon Pet Preform we have now are evenly walled and durable, making them a good choice for more and more customers.
