### What is the manufacturing process of garbage bins?
Garbage bins are typically made using a process called injection molding. This involves several steps:
1. **Designing the Mold**: The first step in manufacturing a garbage bin is to create a mold that will be used to shape the plastic. This mold is typically made of steel and precision machined to the desired shape and size of the garbage bin.
2. **Material Preparation**: The next step is to prepare the raw material, which is usually plastic pellets. These pellets are loaded into a hopper and heated to a specific temperature in a machine called an injection molding machine.
3. **Injection Molding**: Once the plastic pellets are heated to the proper temperature, they are injected into the mold under high pressure. The plastic fills the mold cavity and takes its shape. The mold is then cooled to harden the plastic.
4. **Ejection**: After the plastic has cooled and hardened, the mold is opened and the garbage bin is ejected. Any excess plastic, known as flash, is trimmed off.
5. **Finishing Touches**: The garbage bin may undergo additional processes such as painting, labeling, or assembly of any additional components like wheels or lids.
6. **Quality Control**: Before the garbage bin is packaged and shipped, it undergoes quality control checks to ensure that it meets the required specifications and standards.
Overall, the manufacturing process of garbage bins involves designing a mold, preparing the raw material, injecting the plastic into the mold, ejecting the finished product, adding any finishing touches, and conducting quality control checks before distribution.
