How Foam Molding Machines Work

Foam is now used in many packagings and acts as a cushioning device to prevent the package from being damaged by external mechanical forces.

The foam is made from a foam molding machine. Do you know how the foam molding machine works? Let's take a look together.

First, foam molding machine definition

A machine for injecting a material capable of producing a plastic foam in a space between a container and a film-lined interior when the product is packaged, and forming a foam cushioning material tightly encased by a chemical reaction.

Second, the working principle of foam molding machine

The foam does not appear out of thin air. It must be manufactured by a special process from the foaming equipment.

A foaming device is a device that can make a certain concentration of an aqueous solution (foaming agent) into a foam.

The blowing agent itself does not automatically become a foam, it must pass the mechanical action of the foaming machine to become a foam.

The foaming equipment itself cannot produce foam by air. It is to uniformly disperse air into the aqueous foaming agent solution to achieve the largest possible contact surface of the liquid gas, so that the surface active material in the foaming agent forms on the surface of the liquid film. The electric double layer surrounds the air to form a bubble.

The foaming machine and the foaming agent are a technical system that cooperate with each other and cannot function alone.
