Door latches play an essential role in our security in the home, office, or any other gated place. They provide a physical barrier that prevents unauthorized access and provides a visual deterrent to would-be intruders. Latches are usually made of metal but can also be made of other materials, such as plastic or wood. The manufacturing process of door latches begins with the creation of a mold that will be used to shape the metal. The metal is then heated and formed into the desired shape. Once the metal has cooled, it is either plated or painted to provide a finished look.
