I Why is the extruded parison prone to bending? How to solve it?(1) The main reason for the bending of the parisonIn the extrusion blow molding process, the main reasons for the bending of the parison are as follows.①The flow channel in the die is not smooth or the center of the die is not centered.

(1) Factors affecting the sagging of the parisonIn the process of parison extrusion, the parison is prone to sag due to its own weight, resulting in uneven wall thickness of the parison. The more severe the sagging, the greater the unevenness of the parison wall thickness. Therefore, during the mold

In the production process of extrusion blow molding machines, various problems are always encountered, such as insufficient blow molds. How can we solve some of the shortcomings?

Environmental protection device-blow molding waste gas treatmentThere are many production processes for products, including different processes such as suction molding, compression molding, extrusion, blow molding, injection molding, etc. When processing plastics, heating is required. When the tempe

The blow molding process is a two-way stretching process. In this process, the PET chains are extended, oriented, and arranged in two directions, thereby increasing the mechanical properties of the bottle wall, improving the tensile, tensile, and impact strength. Good air tightness. Although stretch

The soft water bucket is produced with food-grade LDPE raw materials, which is resistant to acid and alkali, suitable for water storage, high-grade food, and some chemical raw materials. This bucket is easy to carry and can be used multiple times. The appearance of the barrel can be designed in two
