Does the compressed air for blow molding machines mainly come from air compressors?

The compressed air for the blow molding machine mainly comes from the air compressor. In the operation of the blow molding machine, compressed air plays a vital role, which is reflected in the following aspects:

First of all, judging from the working principle of the blow molding machine, it uses a specific process to make molten plastic into a tubular parison, then puts the parison into the mold, and immediately injects compressed air into the parison. The compressed air uses its pressure to expand the plastic parison and closely adhere to the inner wall of the mold. After cooling, the mold is opened to obtain the required hollow plastic products. This process clearly shows that compressed air is the key power source for driving plastic parisons.

Secondly, compressed air also plays an auxiliary cooling function during the blow molding process. After the plastic parison expands and fits into the mold, compressed air helps accelerate the cooling of the product, thereby improving production efficiency.

As for the source of compressed air, air compressors produce high-pressure gas by compressing air in the atmosphere. These gases are stored in gas tanks and purified by subsequent treatment equipment (such as filters, dryers, etc.), and are finally transported to gas equipment such as blow molding machines through pipes. Therefore, air compressors are the main source of compressed air required by blow molding machines.

In summary, the compressed air for blow molding machines mainly relies on the supply of air compressors. The air compressor provides a stable and continuous power source for the blow molding machine, ensuring the smooth progress of the blow molding process and the stability of product quality.
