What is the difference between double layer blow molding machine and three layer blow molding machine?

What is the difference between a double layer blow molding machine and a three layer blow molding machine? From the name, it is the difference between two layers and three layers. What is the difference between two and three layers? Please accept this practical popular science!

On the one hand, there are differences in products.

Double layer blow molding machines are equipment that mainly produces double or double layer products. Similarly, it can be proven that three layer blow molding machines are equipment that can produce three layer products.

On the other hand, there are differences in equipment.

The difference in equipment is based on product production.

Like double-layer and three-layer blow moulding machines, these two or more layer blow molding machines are considered multi-layer blow molding machines. The difference between multi-layer blow molding machines and ordinary single-layer blow molding machines lies in the configuration of the machine head. Because the production of blow molded products requires the extrusion of plasticized raw materials through the machine head into the mold for further molding, and the extrusion of raw materials can be said to be the basis of product production. Therefore, the realization of multi-layer products requires the installation of multi-layer machine heads.

Therefore, the difference in equipment between a two-layer blow molding machine and a three-layer blow molding machine lies in the different head configurations. The double-layer blow molding machine is a double-layer head configuration, while the three-layer blow molding machine is a three-layer head configuration, which realizes the production of double-layer and three-layer products.

The difference between a two-layer blow molding machine and a three-layer blow molding machine can be summarized in terms of product and equipment structure. If you are new to the blow molding industry, you may have questions about which type of blow molding machine to choose, whether it is a double layer or a triple layer.

The difference between two-layer products and three-layer products is not particularly significant. Compared to two-layer products, three-layer products have better impact resistance, corrosion resistance, and hardness.

Choosing which type of blow molding machine equipment depends on your product production needs. The application field, usage site, performance requirements, and other aspects of the product are all factors that we consider when selecting blow molding machine equipment.
