Plastic pellets are heated until they melt. This step is crucial as it ensures that the plastic is in the right state to be molded. The temperature and duration of heating depend on the type of plastic being used.

Injection:

The molten plastic is then injected into a mold cavity under high pressure. The mold is designed to have the shape and dimensions of the desired part. The high pressure ensures that the plastic fills the cavity completely and evenly, without any gaps or defects.

Cooling:

The plastic cools and solidifies, taking the shape of the mold. This step requires precise timing, as the cooling rate affects the quality of the finished part. If the cooling is too fast or too slow, the plastic may shrink, warp, or crack.

Ejection:

Once cooled, the mold opens, and the finished part is ejected. The ejection system is designed to release the part without damaging it or the mold. The part may still be warm and fragile at this stage, so it needs to be handled with care.

Trimming and finishing:

Excess material may be trimmed, and additional finishing processes can be applied. Trimming involves removing any leftover flash or sprue from the part, while finishing can include sanding, polishing, and painting. These steps enhance the appearance and functionality of the part and ensure that it meets the required specifications.
