NdFeB magnet – Discs
Neodymium magnet discs have many craft applications and can be used in a variety of ways. For example household, office application, name tags at weddings, small refrigerator magnets, hanging-up posters or white board magnets to hold A4 papers. Different diameter and thick available.
Plastic magnet is powerful neodymium magnet enclosed in a durable plastic housing. As the magnet’s nickle plating is completely covered by plastic cover, these magnets are safe to use in harsh environments especially does well in the underwater application, also the magnet is very durable and will not chip or break from usage.
Manufacturing Process of Plastic Integrated Magnets
Plastic integrated magnets can be implemented by several solution, include insert molding, over molding, ultrasonic welding, and some other fitting modes. The specific mode is determined by the structure of the product and relevant technical specifications. 3/4″ dia. x 3/8″ thick Red Small Round Disc Plastic Integrated Glassboard Magnets
Generally, unmagnetized magnets are inserted into the cavity of the mold which allows the molten plastic material to flow around it. Beside the high molding temperature, injection molding process also accompany high pressure, then require magnets must be held without movement during this process.
Over molding is the most regular mode to make fully encapsulated magnets which can be exposed under the harsh working conditions.
Ultrasonic welding is another option to make fully encapsulated magnets.
Include button screw, and melt rivet type.
