High speed Plastic milk baby feeding bottle machine for bottle making injection blow molding machine

A plastic milk baby feeding bottle injection blow molding machine is a type of equipment used in the manufacturing process of plastic bottles, specifically designed for producing baby feeding bottles through the injection blow molding technique.

Injection blow molding is a two-step process that combines injection molding and blow molding. Here's a brief overview of how the process works:

Injection Molding: In the first step, a preform is created by injecting molten plastic material into a mold cavity. The mold is typically made of steel and has the shape of the desired bottle preform. The molten plastic material is injected under high pressure, ensuring it fills the mold cavity completely.

Blow Molding: Once the preform is created, it is transferred to the blow molding station. The preform is heated to a specific temperature to make it soft and pliable. Then, it is placed in a blow mold, which has the shape of the final baby feeding bottle. Compressed air is blown into the preform, causing it to expand and take the shape of the mold. As a result, the plastic material forms the bottle with a hollow center.

Bottle is a container that can hold liquid or solid, which can be seen everywhere in our life, including medicine bottle, cosmetics bottle and beverage bottle. Due to the rapid development of the petroleum industry, human beings invented high molecular polymer, which is commonly known as plastics. Since then, our bottle materials have changed from single glass or ceramics to various kinds of plastics. Drawing lessons from the long history of glass container blowing process, the extrusion or injection molding plastic mold in relativistic state is placed in the blowing mold, and the mold is inflated by a certain pressure of compressed air to make it close to the cavity wall. After cooling and setting, the mold is demolished to obtain the plastic hollow products with the same shape as the cavity. This is the hollow blow molding process we are familiar with.
