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

Firstly, there are differences in the products.

Double layer blow molding equipment is a device mainly used for producing double-layer or two-layer products, while three-layer blow molding machine is a device that can produce three-layer products.

Secondly, there are differences in equipment.

The difference in equipment is based on product production.
Both double-layer and three-layer blow molding machine are 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 into the mold through the machine head, which can be said to be the foundation of product production. Therefore, the implementation of multi-layer requires the installation of a multi-layer machine head.
Therefore, the difference in equipment between double-layer blow molding machines and three-layer blow molding machines lies in the different head configurations. The double-layer blow moulding machine has a double-layer head configuration, while the three-layer blow molding machine has a three-layer head configuration, which realizes the production of double-layer and three-layer products.
The difference between double-layer blow mold machines and three-layer blow molding machines lies in two aspects: product and equipment structure.
The difference between double-layer products and three-layer products is not particularly significant. Compared to double-layer products, three-layer products have better impact resistance, corrosion resistance, and hardness.
The choice of blow molding machine equipment still depends on the production needs of one’s own products. The selection of blow molding machine equipment is based on factors such as the application field, usage location, and performance requirements of the product.
