There are many classifications of rubber floating balls, such as embedded magnet floating balls, non-magnetic floating balls, and external magnets. Each NBR Float Ball 32*32*14.5 with Two Magnets must be produced according to the applicable working conditions of the customer. Embedding magnets means placing the magnets into the mold during injection molding and molding them in one go. The external magnet is drilled using a drilling machine after the float is completed, usually with 2, 3, and 4 holes. The holes are drilled according to the customer's requirements, and then the magnet is installed and sealed with glue. Welcome customers to call and inquire.
