Magnetic Material Molding

Operating Principle

Magnetic material forming is a process in which magnetic materials are formed into specific shapes by the action of a magnetic field. This allows the molten plastic to flow around the magnet and hold it in place. Once the molding is complete and the magnetic material has cooled, the entire product can be placed in our special magnetizing machine to be charged and fully magnetized.

The magnet can be held in place by a series of pins on the mold that surround it and clamp it in place during the injection process. These pins leave holes in the plastic when the part is ejected from the mold. Insert the pins on the mold into the corresponding holes on the magnet. The diameter of the pin hole is typically 2 - 6 mm, depending on the size of the magnet. When the part is demolded, the pin is removed, leaving a hole in the magnet.

Several common methods of insert molding fixed magnets

plastic cap
The sides of the magnet can be partially covered in plastic to hold it in place. Can be used in conjunction with clamp holders or pin holders to secure the magnet during injection.

groove magnet
Form a groove in the magnet to hold it in place. Can be used in conjunction with a pin holder to secure the magnet during injection.

Step magnet
Create a step feature on the magnet to hold it in place. Can be used in conjunction with clamp holders or pin holders to secure the magnet during injection.

Advantage

1) Magnetic materials have efficient energy conversion and storage capabilities and can play an important role in fields such as electricity, energy, transportation, and electronics.

2) Magnetic materials have less impact on the environment during production and use, and are green and environmentally friendly. Recyclable, conducive to resource recycling and environmental protection.

3) There are many types of magnetic materials. Appropriate magnetic materials can be selected according to different application requirements to meet the needs of different fields.

4) Our magnetic materials have good insulation properties and anti-static properties, which can improve the safety of the equipment.

5) It has good chemical stability and thermal stability and can maintain stable performance under harsh environmental conditions.
