Hollow molding has many advantages. It can produce hollow products with complex shapes to meet different design requirements. Secondly, the manufacturing process is simple and fast, with high production efficiency. Furthermore, hollow products have a lighter weight and good durability, making them suitable for various application scenarios. In addition, hollow forming can also be automated for production, reducing labor costs and improving production quality.

The manufacturing process of hollow molding is also relatively simple, generally divided into the following steps: first, prepare the raw materials and select suitable materials for molding. Next is mold design, designing a mold suitable for hollow molding. Next is the injection of materials, injecting raw materials into the mold while injecting gas or liquid. Forming and curing, after the raw materials are cured, the mold is taken out, and the product is completed.

How to achieve airtightness of hollow formed products in Dalian?

The design phase is an important part of ensuring the airtightness of hollow formed products. During the design process, factors such as the overall structure of the product, sealing method, and material selection of sealing components need to be considered. When designing, efforts should be made to minimize the gaps and holes in the product, design the sealing structure reasonably, ensure that the internal space of the product is isolated from the external environment, and thus achieve good airtightness requirements.

Secondly, material selection also has a significant impact on the airtightness of hollow formed products. Choosing materials with good sealing performance, such as silicone, rubber, polyethylene, etc., can effectively improve the airtightness of the product. In addition, the physical properties and chemical stability of the material should also be taken into account to ensure that the product has good airtightness.

The processing technology is one of the key links to achieve airtightness in hollow formed products. During the production process, it is necessary to use appropriate equipment and processes to ensure the manufacturing accuracy and surface quality of the product. For example, during the welding process, it is necessary to ensure the temperature of the molten pool, the quality of the weld seam, and other requirements to avoid gas leakage caused by gas permeation.

Hollow forming is a commonly used manufacturing process for producing hollow products or components. It mainly involves injecting heated and softened plastic or metal materials into the mold, forming a certain shaped cavity inside the mold, and removing the mold after cooling to obtain the finished product. Hollow molding can be used to produce various products such as bottles, boxes, pipes, parts, etc.

The principle of hollow forming is very simple, which is to inject gas or liquid into the product to form a hollow structure inside the product. In this way, the weight of the product will be greatly reduced, but the strength and rigidity of the product can be improved. Hollow formed products usually have excellent durability and compressive performance, and are widely used in fields such as automotive parts, household appliances, stationery, etc.
