Custom Ferrite & NdFeB Magnets,
Matched to Your Project.
Arc, ring, block, disc, or a custom shape evaluated for manufacturability — in strontium ferrite or NdFeB. Send a drawing, a sample or the operating conditions; we take it from grade selection through sampling, production and export delivery.
Customer Visits & Industry Engagement
Records of customer visits, on-site discussions and industry events from our own projects.
Start From Where Your Project Stands Today
You don't need a finished specification sheet to begin. We start from whatever engineering data or physical parts you currently have.
2D / 3D CAD Drawing
Send us your STEP/DWG drawings. We evaluate grinding tolerances, chamfers, coating requirements, and tooling feasibility before quoting.
Submit Technical Drawings →Physical Sample
Have an existing magnetic part with missing specs? Send a sample to our project team in China: we measure what can be measured, and state plainly what still needs testing.
Request Sample Evaluation →Operating Requirements
Know your motor envelope, maximum temperature (e.g. 150°C), and air gap? We recommend the optimal Ferrite or NdFeB grade for your budget.
Discuss Your Requirements →Two Core Permanent Magnet Systems
We balance magnetic flux density, operating thermal stability, corrosion risk, and total procurement budget between two core industrial material categories.
Core Industrial Focus Hard Ferrite (Ceramic) Magnets
Custom strontium ferrite magnets in wet-pressed, dry-pressed and injection-molded forms, tooled to your drawing or sample.
| Material System | Strontium hard ferrite; injection-molded grades combine ferrite magnetic powder with a thermoplastic binder. |
|---|---|
| Production Routes | Sintered: wet pressed, dry pressed. Bonded: injection molded |
| Magnetic Orientation | Anisotropic or isotropic, depending on grade and process |
| Magnetization Pattern | Axial, diametrical, radial or a multipole pattern |
High-Energy Rare Earth Neodymium (NdFeB) Rare Earth Magnets
Custom sintered, compression molded and injection molded NdFeB magnets for motors, sensors and industrial equipment.
| Material System | Neodymium-Iron-Boron (NdFeB) rare-earth permanent magnet material. |
|---|---|
| Production Routes | Sintered NdFeB · Compression molded NdFeB · Injection molded NdFeB |
| Magnetic Orientation | Sintered: set during magnetic-field pressing. Compression molded and injection molded: isotropic for the materials described on this site. |
| Magnetization Pattern | Direction, pole pattern, pole count and pole location are confirmed per project; the bonded routes are magnetized after molding. |
Who We Help in Industrial Magnet Sourcing
Our operating model is engineered specifically for procurement, engineering, and quality teams confronting these six common challenges:
You Have Drawings & Need a Supplier
You have complete 2D/3D drawings, and need the part placed with a factory whose grinding, coating and batch consistency can be held against those drawings.
You Have a Sample with Missing Data
You have an existing magnetic part from a previous supplier but lack complete grade specifications, magnetization curves, or original CAD models.
You Need an Approved Second Source
Mitigate supply chain single-point failure risks by establishing a qualified, independent secondary production source in China, producing to approved samples and agreed specifications.
Unsure of Material or Grade Selection
You know your motor's torque, speed, and thermal parameters, but need technical guidance selecting between Ferrite (e.g. Y35) and NdFeB grades.
Material Cost Reduction & Substitution
Lower bill-of-material costs by evaluating whether high-grade strontium ferrite or optimized geometries can substitute costly rare earth magnets.
Trapped by a Single Factory's Limits
Avoid vendor lock-in where one factory only makes dry blocks while your project requires precision wet arc segments and multipole sensor rings.
From Your Requirements to Production & Delivery
Our 10-step process covers requirement review, factory matching, sampling, production and delivery. Arrangements are tailored to the project, with ProfurtherMag coordinating communication throughout.
Intake & Feasibility
Start with your drawing, sample or application requirements. We review the available information and clarify what is needed for an initial assessment.
Matching & Quotation
We match the material, shape and process to a suitable manufacturing partner and prepare a quotation covering the agreed requirements.
Sampling & Approval
We coordinate sample checks and your validation. Approved reference samples are retained by us and the producing factory alongside the agreed specifications.
Production & Quality Follow-up
Production follows the approved requirements, with inspection arrangements agreed for the project and progress coordinated with the producing factory.
Delivery & After-Sales
We coordinate suitable protective packaging, shipping documents and delivery arrangements, and remain your contact for repeat orders and after-sales issues.
Cross-Material, Cross-Process Project Matching
We don't force your design into the limits of a single workshop. Your project is matched to the partner factory whose material, shape and process fit it, and the commercial responsibility for the order stays with ProfurtherMag.
Sample & Drawing Technical Evaluation
Customer has a legacy sample, or a partial 2D/3D drawing with no clear magnet grade or magnetization specification. The sample's service history is usually unknown, so wear, corrosion or partial demagnetisation may already have changed the part that has to be reproduced. Grade, orientation and magnetization pattern are undocumented, so nobody has an agreed basis for judging whether a supplied part actually matches the sample.
Every item in the result is labelled for what it is: measured on your part, read from the evidence, or still open. The part in hand is logged with what it shows — dimensions against the drawing, the features that carry the function, the coating or surface condition, and the magnetization the assembly requires. Open items are listed with the test or the sample validation each one needs, and the questions are worked between your engineers and the producing factory's engineers.
Material Selection & Substitution
Customer faces cost pressure using expensive rare earth magnets, or experiences demagnetization with low-grade ferrites.
We work from the operating conditions the customer supplies — service temperature, air gap, available space and annual quantity — to propose alternative grades or optimized geometries.
Second Source Supply Chain Development
OEM is single-sourced with a domestic or local supplier experiencing capacity crunches or uncompetitive pricing.
We establish a second production route at a screened partner factory in China whose process fits the part, under master sample control and with one accountable counterpart.
Key Industrial Applications
Typical magnet requirements across the applications we assess, and what to send us for a first judgement.
Case Studies & Technical Evaluations
Documented project records: the challenge, the technical assessment, the actions taken, and the outcome of the project.
Ferrite Arc Magnets for Water Pump Yokes
The customer required ferrite arc magnets to its own drawing for an existing water purifier pump motor yoke: outer radius R35.5 +/-0.1 mm, inner radius R27 +0.2/0 mm, wall 8.5 -0.1/0 mm, section 63 +/-0.1 mm by 40 +/-0.5 mm, corner breaks to R2, and a grade table of Br 380-400 mT, Hcb 230-275 kA/m, Hcj 235-290 kA/m and (BH)max 27-32.5 kJ/m3. Two segments go into each steel yoke. The magnets had to fit the customer's assembly process before a bulk order could be placed, and the supply scope was the magnets alone: the steel yoke and the assembly stayed with the customer.
| Project Stage | Delivered |
| Customer Starting Point | Drawing |
| Outcome | The first samples passed the customer's yoke assembly check, bulk purchasing followed, repeat orders have continued since 2017, and the series has extended to several arc sizes for other pump motor builds. Production ran to the drawing: outer radius R35.5 +/-0.1 mm, inner radius R27 +0.2/0 mm, wall 8.5 -0.1/0 mm, section 63 +/-0.1 by 40 +/-0.5 mm, end chamfer 2 x 45 degrees, grade Br 380-400 mT, supplied uncoated and unmagnetized. Batches ship as one full 20GP container with 30-35 days of lead time, and acceptance is by assembly in the customer's own yoke. |
Ferrite Arc Magnets for Fan & Blower Motors
The axial fan assembly locates and holds the ferrite arc magnets with U-shaped retaining clips, and each clip works together with a plastic clip holder. The magnet end has to reach a defined seating position at the edge of the plastic holder before the U-shaped clip can engage.With the initial end geometry, one end of a magnet could not fully reach that intended seating position. This prevented secure engagement of the clip and raised a concern about inadequate retention and the magnet coming loose during operation.The requirement was therefore not simply to supply the arc profile shown on a drawing. The magnet end also had to clear the surrounding assembly features and seat correctly at the interface with the plastic holder.
The axial fan project included a chamfer adjustment to address the fit between the magnet end and the plastic clip holder, so the U-shaped retaining clip could engage securely. Samples were confirmed by the customer in its assembly before bulk purchasing.ProfurtherMag has continued working with this customer since 2018, supplying ferrite arc magnets for both automotive axial fan and blower motor applications. The assembly adjustment described here concerns the axial fan project; the blower supply is a separate part of the same customer relationship.
