01 Sintered hard ferrite
Ferrite Magnet Production Equipment
Our ferrite production route starts with in-house powder preparation and continues through pressing, sintering and grinding. Equipment is selected for rings, arc segments, blocks and other ceramic magnet geometries.

Powder production
Preparing the powder before shaping the magnet
Our rotary kiln calcines the raw-material mixture used to make hard ferrite powder. Preparing powder in-house lets the material team work directly with the pressing and sintering operations.
- Material formulationPowder formulation is matched to the ferrite material specification.
- Calcination & millingThermal preparation and subsequent milling establish the feedstock for forming.
- Production feedbackPressing behavior and finished magnetic properties inform material adjustments.
Forming
Wet Pressing
For anisotropic ferrite parts, wet presses compact slurry in an aligning magnetic field. Dewatering and tool geometry are controlled during forming.
Forming
Dry Pressing
Dry presses compact prepared powder into the required shape. The selected route depends on the geometry and magnetic requirements.
Thermal processing
Sintering Furnaces
Furnace processing develops the ceramic structure of the pressed part. Shrinkage must be allowed for in the tooling and finishing plan.
Finishing
Ferrite Grinding Line
Grinding brings sintered parts to their finished dimensions and prepares the surfaces needed for mating or assembly.
02 Sintered NdFeB
NdFeB Forming, Sintering & Diffusion Equipment
Our NdFeB equipment includes electric pressing, automated transfer into the sintering stage and three surface-application routes for grain boundary diffusion. These operations serve different purposes and are chosen around the magnet specification.
Production line
Connecting forming with the next production stage
The line combines forming equipment with handling and furnace loading systems. Controlled transfer reduces repeated manual handling between pressing and sintering.
- Controlled formingForming and demolding parameters are managed for the pressed geometry.
- Automated transferHandling equipment moves the parts between connected production stages.
- Diffusion where appropriateGrain boundary diffusion is evaluated for the required coercivity and magnet dimensions; it is not applied to every grade.
Forming
All-Electric Pressing System
Electric control of forming and demolding loads supports repeatable handling of pressed NdFeB parts before sintering.
GBD source application
Screen-Printing Equipment
Screen printing applies diffusion-source material to selected magnet surfaces before the grain boundary diffusion heat-treatment stage.
GBD source application
Vacuum Deposition Equipment
PVD provides a vacuum-based route for depositing diffusion-source material. Deposition is a preparation step, not the diffusion heat treatment itself.
GBD source application
Automatic Spray Equipment
Spraying offers another route for applying diffusion-source material. Coverage and the process route are selected for the magnet geometry.
Grain boundary diffusion results depend on the base grade, magnet thickness, diffusion source and heat-treatment conditions. Equipment capability alone does not establish a finished magnet’s temperature rating.
03 Injection-molded magnets
Injection Molding Equipment for Magnetic Components
Our horizontal, vertical and rotary-table injection molding arrangements support ferrite- and NdFeB-based compounds. Mold geometry, insert position and the magnetization plan are considered together for magnetic rings, rotors and shaped components.

- 02Mold & insert setup
- 03Injection molding
- 04Magnetization
- 05Dimensional & magnetic checks
Production presses
Horizontal Injection Molding
Horizontal presses support repeat production of molded magnet geometries using magnetic-powder and polymer compounds.
Insert molding
Vertical Injection Molding
Vertical machines provide access for loading shafts, bushings and other inserts when the part calls for insert molding.
Handling automation
Automated Molding Cells
Molding cells combine the press with part-handling equipment to reduce manual transfer between cycles.
Process integration
Molding-Line Handling Equipment
Dedicated handling arrangements are matched to the molded part and its next operation, rather than used as a single setup for every product.
04 Finishing · Tooling · Assembly
Machining & Assembly Equipment
Magnet production does not end at the pressed or molded shape. Ferrite grinding, metal-component machining, toolmaking and assembly equipment establish the finished dimensions and interfaces. Magnetizing equipment supplies the field needed to magnetize the selected material and pole pattern.
Metal components
CNC Turning
Turning equipment machines cylindrical parts, fitting diameters and interfaces for housings and motor components.
Stamping
Progressive-Die Stamping
Progressive-die presses manufacture stamped parts for motor cores and housings. Die condition and geometry are central to dimensional control.
Assembly
Stator Assembly Equipment
Assembly equipment brings prepared components together in the sequence required by the stator design.
HOUSING PRODUCTION
Motor Housing Stamping
Forms steel motor housings using dedicated stamping dies. Housing geometry, mounting features and dimensional consistency are controlled to meet drawing requirements.
Toolroom
Wire EDM for Tooling
Wire electrical discharge machining produces detailed profiles in electrically conductive die and mold components.
Toolroom
Sinker EDM for Mold Cavities
Sinker EDM machines cavities and features in conductive tooling materials that are difficult to produce by conventional cutting alone.
05 Magnetic · Dimensional · Environmental
Inspection & Test Equipment
We use different instruments for material properties, finished-part magnetic output, physical geometry and application-related evaluation. The approved inspection plan identifies the characteristic, fixture, conditions and acceptance criteria.
Magnetic properties
Permanent-Magnet Characterization
Measures hysteresis behavior and derived parameters, including Br, Hcb, Hcj and (BH)max, using the configured sample holder and test method.
Finished magnets
Fluxmeter & Measuring Coils
A fluxmeter and calibrated coil measure magnetic output. A Helmholtz-coil setup determines magnetic moment; the reported quantity depends on the coil, calibration and measurement procedure.
Pole pattern
Multipole Waveform Testing
Checks the field waveform around multipole parts to evaluate pole count, position and consistency using the defined measurement setup.
Material analysis
ICP Composition Analysis
Checks elemental composition to support material analysis. Composition results are separate from a finished magnet’s flux or waveform.
Material investigation
Metallurgical Microscopy
Examines prepared material sections to support investigation of microstructure and process-related features.
Dimensional metrology
Coordinate Measuring Machine
Checks three-dimensional geometry, positions and datum-related features on suitable parts.
Optical measurement
Optical Measuring Station
Supports dimensional inspection of visible part features with the installed optical measurement setup. The measurement method is selected for the feature being checked.
Geometric form
Roundness Measurement
Evaluates circular form on applicable rings, shafts and cylindrical components.
Component metrology
Gear Measurement
Checks specified gear geometry on relevant motor or transmission components.
Appearance checks
Automated Optical Inspection
Screens the visible characteristics configured for the part. AOI is not a substitute for magnetic-property testing or internal-defect evaluation.
Thermal evaluation
Temperature Test Chamber
Supports agreed thermal exposure or cycling tests. Magnetic changes are measured before and after the specified test where required.
Corrosion evaluation
Salt Spray Test Chamber
Evaluates corrosion behavior against a defined exposure method, duration and acceptance criterion.
Mechanical checks
Hardness Measurement
Checks hardness on suitable metal components as required by the component specification.
Packaging evaluation
Transport Simulation Equipment
Supports evaluation of packaging and components under the selected transport simulation conditions.
System evaluation
Motor Dynamometer
Measures motor-system output on the configured test setup. Torque and speed describe the tested motor system, rather than the magnet material on its own.
The measurement method matters. A material-grade result, magnetic flux reading, field waveform and motor test do not measure the same characteristic. Reports should identify the sample, method and test conditions so results can be compared meaningfully.
