These machines are designed to heat the plastic to its melting point, typically around 200-250 degrees Celsius, depending on the type of plastic. The heat softens the plastic, allowing it to flow and take on a molten state. This molten plastic is then extruded through a die, which shapes it into long strands or pellets. The extrusion process is carefully controlled to ensure the plastic is not overheated, as this can lead to degradation and loss of quality.

During the melting process, it is essential to maintain a precise temperature and mixing to ensure the plastic's chemical structure remains intact. This is a delicate step as it requires expertise to avoid burning or under-melting the plastic. Once melted, the plastic is often cooled and then cut into uniform sizes, creating a raw material ready for furniture production. This molten state is crucial as it allows the plastic to be molded, formed, or extruded into various shapes and structures, which will later be used to create the legs, seats, and other components of the furniture.

The molten plastic can be further processed through a process called 'pelletizing', where it is cut into small, uniform pellets. These pellets are then used as a raw material for manufacturing furniture, ensuring consistency and ease of use in the production process. This step is often done in a controlled environment to maintain the quality and purity of the recycled plastic.

In summary, the melting process is a vital stage in recycling plastic into furniture. It requires precise temperature control and specialized machinery to transform shredded plastic into a usable, molten state. This molten plastic can then be shaped, formed, and used to create durable and sustainable furniture pieces.
