Custom Magnetic Holding Magnets for Industrial Mounting, Clamping & Positioning

Backed by our ISO 9001 certified quality management system and full compliance with RoHS and REACH environmental standards, we ensure every assembly meets stringent international industrial requirements.

What Are Magnetic Holding Magnets?

Magnetic holding magnets are permanent magnetic assemblies designed to attach, position, clamp, or mount ferromagnetic components without conventional mechanical fasteners.

A standard assembly combines a permanent magnet (Neodymium or Ferrite) encased in a steel housing or cup. For pot-style configurations, the steel shell redirects the magnetic flux lines toward the working face, generating high holding force from a compact structural footprint.

Targeted Industry Applications

Our custom assemblies are engineered to integrate seamlessly across diverse manufacturing and operational sectors:

Automation & Robotics: End-of-arm tooling, sensor brackets, and quick-change positioning fixtures.

Automotive Assembly: Temporary vehicle body positioning fixtures, welding jigs, and inspection templates.

Industrial Lighting & Displays: Quick-release LED housing mounts, exhibition signage, and architectural display brackets.

Medical Equipment: Removable diagnostic panels, equipment access doors, and portable accessory holders.

Available Configurations

Pot Magnets: Neodymium (NdFeB) and Ferrite variants in flat or recessed designs.

Mounting Variations: Internal threaded holes, external threaded studs, countersunk holes, and through-holes.

Protective Housings: Rubber-coated and plastic-coated assemblies to prevent surface scratching and increase friction.

Custom Assemblies: Tailored dimensions, multi-pole arrangements, and specialized steel shell geometries for OEM integration.

Engineering Advantages of Custom Assemblies

Optimized Holding Force vs. Envelope Size
Nominal material grades do not dictate real-world performance. Actual holding force is governed by multiple variables:

Magnet grade and volume
Steel housing geometry and thickness
Contact surface area and air gap thickness
Target material composition (low-carbon steel vs. alloy steel or stainless steel)
Loading direction (direct pull-off force versus shear force)

Engineering the magnetic circuit specifically for your application eliminates the need to oversize components just to compensate for poor design matching.

Steel Housing Protection and Circuit Control
The steel cup protects brittle permanent magnet materials from direct mechanical shock while serving as a flux-focusing circuit. Housings can be manufactured with custom mounting features:

Flat-bottom cups for flush resting
Threaded studs and internal threads for bolted integration
Flanged or special-shaped shells designed to fit restrictive OEM installation envelopes

Material Selection: NdFeB vs. Ferrite
Neodymium (NdFeB): Selected when maximum holding force is required within tight spatial constraints. Ideal for machine fixtures, positioning systems, industrial brackets, and compact tool holders.

Ferrite: A cost-effective alternative for larger assemblies, high-temperature thresholds, or general-purpose mounting where absolute maximum pull force is secondary to material economy.

Precision Mounting Structures

The method of integration is engineered to match your assembly process:

Mounting Type	Mechanical Feature	Primary Application
Internal Threaded Hole	Recessed female thread	Front-side attachment using standard bolts or screws
External Threaded Stud	Protruding male stem	Pass-through mounting secured with a standard nut
Countersunk Hole	Angled bore for flat-head screws	Flush surface mounting without fastener interference
Through-Hole	Plain bore for pass-through bolts	Direct structural bolting

Surface Treatments & Environmental Protection

Because uncoated NdFeB magnets are susceptible to oxidation, protective plating is applied according to operating conditions:

Nickel & Zinc Plating: Standard corrosion resistance for indoor and general industrial environments.

Epoxy Coating: Enhanced barrier protection for humid or mildly corrosive settings.

Rubber and Plastic Coatings: Provide friction, eliminate metal-to-metal impact, and protect painted or finished surfaces from scratching. Essential for vehicle accessories, temporary positioning fixtures, and sensitive metal-frame attachments.

How Custom Engineering Solves Purchasing Challenges

Dimensional Constraints: Custom outer diameters, heights, and shell profiles prevent installation interference.

Installation Friction: Customized studs, threads, and countersinks streamline assembly times compared to gluing or clamping loose magnets.

Inconsistent Pull Force Data: Pre-defining testing parameters (such as testing on a standardized 10mm low-carbon steel plate) ensures performance consistency across production batches.

Corrosion Failures: Matching plating types to specific operating temperatures and humidity levels prevents premature degradation.

Surface Damage: Deploying rubber-coated variations protects high-finish target surfaces while preventing lateral slippage under shear loads.

Quality Control & Inspection Protocols

To guarantee batch-to-batch consistency, rigorous inspection protocols are established prior to production based on your technical agreement:

Dimensional Inspection: Verification of outer diameters, thread pitches, and housing tolerances using calibrated gauges.

Pull Force Verification: Practical pull tests conducted using specialized tension-testing equipment against standard test plates to verify holding performance.

Coating & Surface Checks: Visual and thickness inspections to verify plating integrity and defect-free rubber/plastic encapsulation.

Structural Assembly Verification: Checking adhesive bonds, thread depth, and mechanical alignment of housing components.

FAQ

Q: What are magnetic holding magnets used for?

A: They are used for mounting, fixing, positioning, clamping, holding, and attaching components to ferromagnetic surfaces. Typical applications include fixtures, equipment panels, brackets, displays, tool holders, machine components, and OEM products.

Q: Can you manufacture custom magnetic holding magnets?

A: Yes. We can customize the magnet size, magnetic material, grade, steel housing, thread, stud, countersunk hole, coating, rubber covering, packaging, and other assembly details according to customer requirements.

Q: Are your magnetic holding magnets made with neodymium?

A: Neodymium (NdFeB) is available for applications requiring high magnetic force in a compact size. Ferrite is also available for applications where cost, size, or other material characteristics are more suitable.

Q: Can I specify the required pull force?

A: Yes. Pull force can be used as one of the main design requirements. However, the target force should be evaluated together with the steel target, air gap, contact area, surface condition, and loading direction.

Q: Why is the actual holding force lower than the catalog value?

A: Catalog pull-force values are normally measured under controlled conditions with direct contact to a suitable steel plate. Paint, gaps, thin steel, uneven surfaces, non-magnetic materials, and shear loading can significantly reduce the effective holding force in real applications.

Q: Can you add a threaded hole?

A: Yes. Internal threaded holes, external threaded studs, through holes, countersunk holes, and other mounting structures can be customized.
