1. How does the process work?

In custom plastic injection molding, the process involves several key steps:

1. Designing the Mold: First, a mold is designed based on the specifications of the part required. This mold can be made from various materials, often steel or aluminum.
2. Heating the Plastic: Plastic pellets are heated until they melt. This melt is then ready to be injected into the mold.
3. Injecting the Plastic: The melted plastic is injected into the mold under high pressure. This ensures that every detail of the mold is filled.
4. Cooling: After injection, the plastic is allowed to cool and solidify within the mold.
5. Demolding: Finally, the mold opens, and the finished part is ejected.
