The phenomenon of PVC cartoon ornaments edge breakage and adhesive breakage seriously disrupts the quality of PVC products. PVC enamel edge breakage has become a common phenomenon in the flat vulcanization process. In this regard, many PVC doll manufacturers are prone to edge breakage when their hardness is low and they have circular or cylindrical shapes. Therefore, PVC consumer manufacturers summarize several reasons for edge breakage!
The main reason for this is that PVC cartoon pendant have a certain degree of curvature when the hardness of the product is low, and there is a certain internal gap when the mold is closed on and off, which can cause the product to explode. Common products are low hardness circular products, and the main reason is that there is an error in the mold accuracy, and there is a large amount of CNC correction and tool compensation during the mold processing.
The activity of the raw materials is too poor, and the raw materials are actually low hardness, so there is an error in participating in PVC and vinyl silicone oil. In addition, the machine itself has a phenomenon of explosive edges in terms of time, temperature, and pressure adjustment points. This phenomenon can be adjusted by the machine! The processing and vulcanization speed is unstable. When the temperature between the machine and the mold rises or falls, the product often exhibits bursting and bulging phenomena. When adjusting the machine temperature and time, it often forms a cycle, and the bursting of the product is not treated!
Treatment method: when processing the mold, try to reduce the gap between the upper and lower molds, adhere to the normal curing process consumption in the processing of PVC doll products consumer manufacturers, increase the mixing degree of raw materials and vulcanizates in the mixing process, try to make the raw materials mix evenly, control the product weight and placement method in the consumption process, reduce the machine table temperature, reduce the product edge cracking temperature, and prevent the product from edge cracking. But when it comes to controlling the PVC doll edge burst phenomenon, a better way is to ensure that the machine operates normally and the mold enters and exits smoothly to ensure the product is functioning properly!
