How Does Injection Molding Work

Injection molding is a precise and versatile manufacturing process that transforms raw materials, typically plastic or rubber pellets, into intricate and custom-designed components. The process involves the following key steps:

Material Melting

Raw material is fed into the injection molding machine in the form of small pellets. These pellets are then heated to a molten state within the machine.

Injection

The molten material is injected into a mold cavity under high pressure. The mold, usually made of steel or aluminum, is precisely shaped to form the desired product.

Cooling

Once injected into the mold, the material begins to cool and solidify, taking the shape of the mold. Cooling is a crucial phase to ensure the final product retains its intended form and properties.

Ejection

After the material has sufficiently cooled and solidified, the mold opens, and the newly formed part is ejected. This marks the completion of one cycle of the injection molding process.

Cycling

The process is highly automated and can be repeated in a continuous cycle, producing a large volume of identical parts with high precision and efficiency.
