What is the impact of blowing pressure on product quality when blow molding products are produced?


Author: MULAN -Plastic Molding Manufacturer

During the production of blow molding products processing plant, blowing compressed air has two main functions: 1 to make the tube billet expand and cling to the wall of the mold cavity to form the required shape; 2 is to play a cooling role. Depending on the type of plastic and the temperature of the parison, the blowing pressure is also different. Appropriate blowing pressure has an intuitive impact on the shape and pattern of the product. Come see it today when What are the effects of excessive blowing pressure or too small blowing pressure when blow molding products are produced? Insufflation pressure is too high First, there will be overflow; secondly, when the blowing pressure is higher, the parison will expand rapidly when it is inflated, which will easily cause the bottom and surrounding of the container to break. Generally, lower pressure is used for small volume and thick wall products. Insufflation pressure is too low General large-volume and thin-walled products, Blow molded products processing plants will use higher blowing pressure. If the pressure is too low, after the parison is clamped into the mold, it will be cooled before inflation, and the wall thickness and volume of the container will be too small. And when the pressure is insufficient, weld lines are prone to appear on the surface. Generally, the blowing pressure determines the temperature of the parison, the temperature of the mold, the size and thickness of the container. Therefore, a professional blow molding product processing factory has a strong grasp of the blowing pressure during production.
