Gas Assisted Plastic Injection Rattan Chair Mould Supplier

Injection molding can also be done with the help of gas that is blown at high velocity inside the mold, pushing the molten plastic out of certain parts of the mold. This creates channels in the plastic form that make the chair much more lightweight while at the same time maintaining its strength. All of the other aspects of injection molding remain the same, but the result is a chair with some parts that are hollow and other parts that are solid.

The plastics used in the chair-making process are usually a composite of several different types of plastics all blended together during the heating part of the molding process. This makes the chair much stronger than it might be if only one type of plastic was involved.
