Which is better for multi-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 point of view, it is the difference between double and triple. What is the difference between double and triple layers? Please accept this practical science! On the one hand, this is a product difference. Double-layer blow molding machine is the equipment that mainly produces double-layer or two-layer products. The same reason can prove that the three-layer blow molding machine can produce three-layer products. On the other hand, the equipment is different. The difference in equipment depends on the production of the product. Like the double-layer blow molding machine and the three-layer blow molding machine, the two-layer and more than two-layer blow molding machine equipment can be regarded as a multilayer blow molding machine. The difference between a multi-layer blow molding machine and an ordinary single-layer blow molding machine lies in the structure of the die, because the production of blow molding products is to extrude the plasticized raw material through the die and then further shape it. It's in the mold. Extrusion can be said to be the basis of product production. Therefore, the realization of the multilayer requires a multilayer head. Therefore, the difference in equipment between the two-layer blow molding machine and the three-layer blow molding machine is the different head structure. The double-layer blow molding machine has a double-layer head structure, and the three-layer blow molding machine has a three-layer head structure, which also realizes the production of double and three-layer products. The difference between double-layer plastic blow molding machine and three-layer blow molding machine can be summarized in two aspects: product and equipment structure. If you are a newbie in the blow molding industry, then you may have questions about which blow molding machine to choose (whether it is dual or triple mold). The difference between a two-layer product and a three-layer product is not particularly large. In contrast, three-layer products are better than two-layer products in terms of impact resistance, corrosion resistance and hardness. Similarly, the choice of blow molding machine equipment depends on your production needs. When choosing blow molding machine equipment, you must consider the product's application field, use place, performance requirements, etc. If you really don’t know anything about double-layer blow molding machines, you can put forward your own product production requirements and consult the blow molding machine equipment manufacturer. The manufacturer will tell you to choose a double-layer blow molding machine or a three-layer blow molding machine according to the actual product requirements. Blow molding machines are better.
