In the plastics industry, material purity is essential for the smooth operation of injection molding machines. Even tiny metal contaminants can damage the screw or mold or reduce the quality of the final product. That is why magnetic separators for injection molding machine hoppers are used to capture ferromagnetic particles before the material enters the machine.
The most commonly used types include the SM, TM, and TM FL separators.
Star-shaped hopper magnet SM
The SM star-shaped magnetic separator is used for basic separation of metal contaminants from plastic pellets. Thanks to its simple design, it offers an affordable solution for standard operations.
Main advantages:
- low purchase price,
- simple design,
- easy installation in the hopper,
- strong neodymium magnets.
During cleaning, the captured metal contaminants must be removed manually directly from the magnets.
Hopper magnet TM
The TM magnetic separator is designed to separate ferromagnetic contaminants from plastic pellets directly in the injection molding machine hopper. The separator’s design ensures uniform material flow through the magnetic tubes.
Main advantages:
- high separation efficiency,
- easy cleaning,
- magnets housed in stainless steel tubes,
- quick maintenance without the need for manual removal of contaminants.
During cleaning, simply slide the magnetic core out of the stainless steel tube and the captured metal particles will fall out on their own.
Hopper magnet TM FL
The TM FL magnetic separator is based on the TM design but is additionally equipped with a special collar that eliminates dead spots during material flow.
Main advantages:
- elimination of dead spots,
- ensuring all material passes through the separator,
- higher separation efficiency,
- easy cleaning and maintenance.
Thanks to this design, the TM FL is particularly suitable for operations with high demands on separation quality.
