Injection moulding of magnets is a forming technique for thermoplastics, thermosetting polymers and metals with a low melting point.
In the injection moulding process we melt plastic, supplied as a granulate or powder, to form a fluid mass and then inject it at high pressure into a mould in which the cavity has the shape of the desired product. As it cools the plastic solidifies, resulting in the desired product.
An advantage of a thinner product is that the cost price can be kept low and products cool off more quickly, making it possible to attain a cycle time of just seconds. Injection Molding Plastic Magnets, injection moulding neodymium magnets
Multiple-cavity moulds are also used, which is to say that a single mould contains several cavities of the same shape, making it possible to produce a large number of the same product during each cycle.
Injection moulding is one of the most commonly used forming techniques for plastic parts and makes it possible to produce complex products. Due to the relatively high cost of making a mould, however, injection moulding of magnets is only suitable for high volume production.

We can achieve densities well beyond the industry norm and this helps our customers achieve the very best performance and durability in high technology motor and other applications. In some cases this has allowed clients to replace the more expensive sintered NdFeB permanent magnets.
MPCO is also on the forefront of application development for injection moulded isotropic and anisotropic permanent magnets.
