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

What is the difference between a double layer blow molding machine and a three layer blow molding machine? Judging from the name, it is the difference between double and triple. What is the difference between double and triple? Please accept this practical science!

On the one hand, it is the difference in products.

The double-layer blow molding machine is a device that mainly produces double-layer or two-layer products. Similarly, it can be proved that the three-layer blow molding machine is a device that can produce three-layer products.

On the other hand, is the difference on the device.

The difference in equipment is based on product production.

Like double-layer blow molding machines and three-layer blow molding machines, blow molding machines with two or more layers are considered multi-layer blow molding machines. The difference between a multi-layer blow molding machine and an ordinary single-layer blow molding machine lies in the configuration of the machine head, because the production of blow molding products is to extrude the plasticized raw materials through the machine head, and then go into the mold for further molding. Extrusion can be said to be the basis of product production, so the realization of multi-layers requires setting up multi-layer heads.

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

The difference between a double-layer blow molding machine and a three-layer blow molding machine can be summed up in two aspects: product and equipment structure. If you are just getting into the blow molding industry, you may have questions about which blow molding machine equipment to choose, double-layer or triple-layer.

The difference between double-layer products and three-layer products is not particularly large. In comparison, three-layer products are better than double-layer products in terms of impact resistance, corrosion resistance and hardness.

In the same sentence, which blow molding machine equipment to choose depends on the production needs of your own products. Including the application field of the product, the place of use, performance requirements, etc., are all factors we consider when choosing blow molding machine equipment.

You can bring your own product production requirements to consult the MEPER MACHINE blow molding machine equipment manufacturer. We will tell you whether it is better to choose a double-layer blow molding machine or a three-layer blow molding machine according to the actual product requirements.
