Magnetic Materials
Foresee Group is a premier manufacturer of a wide array of hard and soft magnetic materials. Each material is carefully and skillfully produced in-house. Magnetic materials can be used more than anything else for their magnetic properties. The magnetic response of a material is determined by the magnetic dipole moment associated with the natural angular impulsive force, or spin, of its electrons. A material’s response to an applied magnetic field can be characterized as diamagnetic, paramagnetic, ferromagnetic or antiferromagnetic.
Highest Energy Magnets. NdFeB alloys provide the highest energy product of all permanent magnet materials and coercivity as high as 35 kOe.
Alnico’s energy product ranges from 1.0 to 10.0 MGOe and it is produced in both Sintered and Cast. Alnico alloys have the highest Curie temperatures of any magnetic material, around 800°C, Low Temperature Coefficient, and Operating Temperatures up to 550 °C.
Produce in sintered form in alloys of SmCo5 and Sm2Co17. It energy products ranging from 18 to 32 MGOe, and Coercivity can exceed 30 kOe. SmCo alloys have low temperature coefficients of induction and coercivity.
Bonded Magnets are typically manufactured via compression or injection molding processes, with NdFeB and Ferrite being the dominant magnetic components. A wide variety of binders are available. They exhibit high structural integrity, high resistance to corrosion and can be formed into complex shapes.
This low cobalt material can be machined as if it was soft steel. The simplified machinability, magnetization with its high working temperature and greatly reduced cobalt content enable it to surpass other permanent magnet materials in many applications.
A soft magnetic material can be used as an efficient enhancer of the working flux in a large variety of devices including transformers, generators, motors and power distribution equipment.
The CIM process produces a nit-shape product that is suitable for high volume production of complex-shaped components with tight tolerances. CIM parts are commonly used in the medical, optical, automotive, microelectronics and other industries that requires complex geometries, different profiles, wall thickness and undercuts.
Foresee offer expertise in the research, development and application of all magnetic materials, alloy parts and others.
Magnetic Assemblies, Modules & Motors
Foresee manufactures magnetic assemblies, modules, motors and devices to meet customers’ needs in many industries.
Magnetic assemblies are units combining permanent magnets with magnetic and/or non-magnetic components to create a magnetic field in a given space or a strong holding force than a monolithic magnet of the same size. Our automated assembly lines are designed to establish production efficiencies, high quality, factor in competitive costs, reduced or eliminate variability in each assembly, and improve safety for staff.
Magnetic modules are products or semi-finished products that realizes the application function after the magnetic materials are assembled with other materials. It is widely used in motor stators and rotors, sensors, filters, jacks, magnetic separators, magnetic pumps, speakers, and other products or devices.
Halbach Arrays
The Halbach arrays are a magnetic assembly that enhances the magnetic field on one side of the array and reduces it on the other. Halbach arrays provide higher fields than magnets of the same size.
Precision Magnetic Sub-assemblies
Magnetic sub-assemblies are units combining permanent magnets with magnetic and/or non-magnetic parts to interface with other components in the finished product. These assemblies can be integral components of motors, smartphones, generators, radar, computers, and a vast array of other devices.
Magnetron & Sputtering Assemblies
Magnetron sputtering is a high-vacuum coating technique which creates high-density films with superior adhesion to the substrate that confine the plasma near the surface of a target to enhance the deposition rate and usage efficiency of the target material.
Vibration Motors
Haptic motors are used to create vibratory feedback and notification in consumer electronic devices, vibration is generated through rotating an unbalanced mass or linearly oscillating a mass undergoing simple harmonic motion between springs.
Haptic Modules
Haptic modules are the essential parts in compact audio systems, where permanent magnets generate the magnetic field that causes the voice coil to oscillate when an AC excitation current is applied.
Permanent Magnet Motors for Power Tools & Automotive
Permanent magnet motors are a type of brushless electric motor that uses permanent magnets rather than winding in the field. It is more efficient than traditional induction motors or motors with field windings for certain high-efficiency applications such as electric vehicles.
