The blow molding machine is a key piece of equipment used to manufacture plastic bottles and containers, and its efficient molding process and flexibility make it the equipment of choice for a variety of industries, including food and beverage packaging, cosmetics, cleaning supplies, and more.

Blow molding machines are divided into two types: semi-automatic and fully automatic.Whether it is a semi-automatic or fully automatic blow molding machine, the preform needs to be irradiated with high temperature by infrared rays to soften it. This step can make the plastic bottle preform softer and more plastic, preparing it for subsequent molding.

Next, the preheated preform is placed into the mold. On semi-automatic blow molding machines, this step typically requires the operator to manually place the preforms inside the mold. The fully automatic blow molding machine uses a robot to complete the placement of bottle preforms. The robot arm has high-speed and precise operation capabilities and can quickly and accurately place the preforms into the mold.

Finally, high-pressure gas is applied to the mold to inflate the preform. This step causes the preform to gradually fit into the inner wall of the mold, forming the inner and outer shape of the bottle or container. By controlling the air pressure and inflation time, the thickness and capacity of the bottle can be adjusted to meet different needs.

The fully automatic blow molding machine greatly improves production efficiency by combining robot operation and inflation steps. Compared with semi-automatic blow molding machines, fully automatic blow molding machines can achieve unmanned operation, reducing human input and the possibility of operating errors, thereby increasing production speed.
