Hollow forming technology has broad market prospects in a wide range of fields. With the continuous innovation of production technology and people's pursuit of energy conservation, environmental protection, high quality, and intelligent production, hollow forming technology will increasingly be favored by the market and become one of the important trends in the future development of manufacturing industry. Meanwhile, with the continuous innovation and development of technology, the hollow forming process will become increasingly mature, and the demand in different fields will inject new impetus into its market value.

Hollow forming is a widely used molding method in the field of plastic processing, which can produce hollow products with different shapes, such as bottles, cans, pipes, bowls, and so on. Hollow forming technology is mainly applied in the fields of food packaging, drug packaging, cosmetics packaging, daily necessities packaging, industrial supplies packaging, and so on. In this article, we will provide a detailed introduction to the principles, processes, and applications of hollow forming technology.

Comparison between Dalian Hollow Forming and Traditional Hard Packaging

Compared to traditional hard packaging, hollow forming technology can achieve faster forming speed. Because hollow forming technology can complete the entire forming process in a short period of time, while traditional chemical packaging requires a longer forming process, the forming speed of hollow forming technology is faster, which can significantly increase packaging capacity and meet market demand.

Secondly, hollow forming technology also has certain advantages in the cost of manufacturing forming molds. Compared to traditional hard packaging, the manufacturing cost of forming molds using hollow forming technology is lower because the manufacturing process of forming molds using hollow forming technology is simpler, resulting in lower costs. This is also one of the important reasons why hollow forming technology can be applied more quickly in practical production.

In terms of packaging material performance, hollow forming technology is also superior to traditional hard packaging. Hollow forming technology can create lighter packaging, thus saving materials, while also producing stronger packaging with better protection effects. Traditional hard packaging materials are relatively thick, not only heavy, but also difficult to fold and store.

Hollow forming technology is an efficient, energy-saving, and environmentally friendly manufacturing process that mainly heats polymer materials to a molten state through an injection molding machine, and then injects the molten material into the filling air of the inner cavity through pressure, forming a hollow structure with sealing and uniform texture. It is widely used in various fields such as translucent bottles, construction, cold drinks, food, health products, cosmetics, medical devices, electronic products, and has broad market prospects.

In the hollow forming process, the industrial machine used is equipped with a metal shaft, and the lower end of the shaft is fixed with the same mold. The hot mold on the shaft extrudes the formed plastic into the mold through the high-pressure air flow, and then expands and shapes it by blowing. The extruded plastic drum needs to be cooled and the internal structure formed needs to be reshaped. Before cooling and solidification, the plastic is still in an expanding state, and its internal shape can be adjusted by adding an air intake system to control the internal structure of the molding process.
