Blow molding is forming by blowing and expanding preheated plastic products in a molding mold.

Blow molding originated in World War I, and the technology of blowing balloons developed into blow molding technology. After years of development, it has gradually been applied to packaging, toys, medical, automobiles, construction, and other fields.

Blow molding has now become one of the mainstream technologies in the plastic molding industry.

1. Orientation of blow molding
The orientation of blow molding mainly includes the following three aspects:

①. Production efficiency direction:
The development trend of blow molding technology is high efficiency, fast speed, and automation, and industrial-level production is achieved in production efficiency;

②. Environmental protection direction:
With the popularization of environmental awareness, the energy-saving and environmental protection characteristics of blow molding are gradually valued, and the product development focuses on material recycling and reducing waste gas emissions;

③. Continuous innovation direction:
While the technology is constantly innovating, the application scope of blow molding is also constantly expanding, constantly introducing new ideas, and developing from a single field to multiple fields.

2. Technical advantages and market prospects of blow molding
The technical advantages of blow molding are mainly reflected in the following aspects:

1. Products of different shapes can be produced;

2. Fast production speed and low cost;

3. Low requirements for the production environment, no need to use mold release agents, molding liquids, and other substances, and little pollution to the production environment;

4. There are many types of plastic materials, and different materials can be selected according to product requirements.

From the perspective of market prospects, the application areas of blow molding products are gradually expanding, especially in the fields of food, medical equipment, petrochemicals, etc., and the market demand is proliferating. With the improvement of the quality of life, people’s requirements for packaging are getting higher and higher, which will promote the further development and application of blow molding technology.

3. Future development trend of blow molding

The future development trend of blow molding technology mainly includes the following aspects:

1. Advanced intelligence: Under the background of rising labor costs and continuous development of artificial intelligence technology, the blow molding industry will gradually realize automated and intelligent production;

2. Diversified application: Blow molding will develop in the direction of diversified material combination, functional structuring, etc., and the application range of products will be wider;

3. Green and sustainable: With the improvement of environmental awareness, green and sustainable will become the mainstream direction of the industry, and the blow molding industry will pay more attention to the research and development, and application of environmentally friendly materials.

In general, blow molding technology has developed into one of the mainstream technologies of a forming process. With the improvement of industrial automation and environmental awareness, blow molding technology will become increasingly important in the future.
