Neodymium magnets installed in central granulate feeding systems have a very practical task: capturing ferromagnetic impurities before the material reaches the machine’s barrel and screw.

The neodymium magnet has a very strong magnetic field, so it stops such particles before they:
• they will damage the screw,
• they will scratch the barrel,
• they will clog the nozzle,
• will deteriorate the quality of the final product,
• will cause hot runner failure.

A well-selected magnetic separator gives:
• less injection molding machine failures,
• longer service life of the screw and barrel,
• fewer defective products,
• more stable quality of final products,
• lower risk of production breaks.

In plastics processing plants, it is often a very cheap element that protects the very expensive plasticizing system.
