Blow molding will have the following development trends in materials, machinery, auxiliary equipment, control systems, and software as the market demands its products.

(1) In order to meet the requirements of functions and properties (medical and food packaging) of blow molding products, the raw materials of blow molding grade will be more abundant and the processing performance will be better. For example, PEN materials not only have high strength, good heat resistance, strong gas barrier properties, transparency, and ultraviolet radiation resistance, but are suitable for blowing various plastic bottles, and have high filling temperature and excellent barrier properties against carbon dioxide gas and oxygen. And resistant to chemicals.

(2) There will be a large increase in product packaging containers and industrial products, and injection blow molding and multi-layer blow molding will have rapid development.

(3) Precision and high efficiency of blow molding machinery and equipment blow molding machinery; auxiliary production (operation) automation of equipment. “Precision and high efficiency” not only refers to the high speed and high pressure of mechanical equipment in the production molding process, but also requires the products produced to achieve high stability in terms of dimensional fluctuations and weight fluctuations, that is, It is said that the dimensions and shape of each part of the produced product have high precision, small deformation and shrinkage, and the appearance, internal quality and production efficiency of the product must reach a high level. Auxiliary operations include deflashing, cutting, weighing, drilling, leak detection, etc. Process automation is one of the development trends.

(4) The research on the blow molding mechanism of blow molding is more in-depth, and the mathematical model of blow molding is rationally constructed. The rapid and accurate numerical algorithm is the key to simulation. The blow molding simulation will play a role in product quality prediction and control. More and more important role.
