Ring Injection Bonded Ferrite Magnets are a combination of good magnetic strength and strong physical properties. The magnets can be easily manufactured on a large scale with close dimensional tolerances and need no finishing operations, thus saving costs. Ashvini Magnets offers a range of injection bonded ferrite magnets that are recognised for high durability and utility. The magnets can be manufactured as per design or custom designed to suit the applications.
For a famous magnet company in the pneumatic field we have realized 1000. 000 injection ferrite rings and 100.000 neodymium rings for pneumatic cylinder magnetic sensor.
The final customer’s need was to improve sensor’s reading precision reducing dimensions.
His first solution was a plasto-ferrite ring, axially magnetized. The low properties of this magnetic material forced the use of a lumbering magnet, beyond the necessity of keeping the ring very close to the sensor for a better reading.
Our work, instead, focused on the realization of sintered neodymium magnet ring, axially magnetized and coated with epoxy resin. Injection Ferrite Ring Pneumatic Cylinder Positioning Magnet
The ring magnetic performances, definitely higher than previous solution, allowed to reduce sensor’s dimension, offering a more precise reading. Consequently, the distance between magnet and sensor increased. The axial magnetization of neodymium ring has been realized more perpendicular comparing with the one of plasto-ferrite magnet. In the end, epoxy coating has garanted a longer life of pneumatic cylinder. Standard Air Cylinder Magnet Injection Mould Ferrite Ring
End customer has finally obtained a better sensor’s precision, putting on the market an evolved system, with reduced sizes. Pneumatic Cylinder Sensor Magnet Injection Plastic Ferrite Material , Ring Ferrite Magnet for Magnetic Cylinder Sensors
MPCO is able to projects and produce customized magnets, to satisfy every customer needs. Plastic Bonded Ferrite Pneumatic Cylinder Ring Magnet
The Complete Magnet Piston fulfills a large number of technical requirements within the pneumatics industry with its double-acting operation, dynamic sealing capability, guidance feature and mechanical end cushioning. An NBR O-Ring acts as a static seal and seals the rod while an integrated magnet detects position. The dimension, magnet flux and return spring groove can all be customized to specific requirements.
