We supply complex Molded Neodymium Slider Magnets, made to your specifications.
They are used for integration into wearable accessories, jewelry clasps, and locking mechanisms.
As seen in our product photo, this is not a simple block.
It features a unique “Bead” Geometry with three distinct features:
– Stadium Through-Hole: An elongated oval hole designed to accommodate flat straps, leather bands, or webbing.
– Raised “Boss” (Step): A rectangular platform on the top face that acts as a mechanical key or mating surface.
– Contoured Profile: Soft, radiused outer edges designed for ergonomic comfort against the skin.
This magnet functions as both a mechanical slider and a magnetic lock.
It eliminates the need for separate housings.
The Design Logic: Wearable Engineering
Why is it shaped this way?
1. The “Strap-Fit” Hole:
Standard round rings cannot accommodate flat materials.
For example, a watch strap or leather bracelet) without bunching up the fabric.
The Solution:
The Stadium (Oval) Aperture allows a flat strip to slide through smoothly.
And prevents the magnet from rotating on the strap.
2. The Mechanical Step (The “Click”):
The Function:
The raised rectangular section on top is likely designed to fit into a matching recessed metal plate or clasp.
The Benefit:
– This provides shear resistance.
– The step locks the magnet in place mechanically.
– And the magnetic force holds it down vertically.
– This creates a secure, premium “click” feel when closed.
Manufacturing Method: Pressed-to-Shape
This shape is too complex to slice.
Molding Technology:
This complex geometry cannot be machined from a standard block.
It is produced via Press-Molding.
It means to press the magnetic powder into a custom die before sintering).
Tooling:
Custom shapes like this generally require a one-time mold fee.
Consistency:
Molding ensures that the complex curves and the “step” height are identical on every single piece.
This is critical for mating clasps.
Surface Coatings: The “Gunmetal” Look
The photo shows a dark, high-end finish.
This is a key selling point for fashion items.
For wearable applications, aesthetics are as important as strength.
Black Nickel (Pearl Nickel / Gunmetal):
– As shown in the photo.
– A dark, glossy, metallic finish that looks like jewelry hardware rather than an industrial component.
Gold / Rose Gold:
– Available for luxury jewelry applications.
Standard Nickel:
– Bright Silver.
Epoxy:
– For durability against sweat/skin oils.
Magnetization Orientation
Through Thickness:
The standard orientation.
Configuration:
The Top Face (with the raised step) is typically one pole.
It attracts the mating metal clasp.
Applications
Jewelry Clasps: The core component of a magnetic leather bracelet clasp.
Paracord Beads: Magnetic sliders for tactical gear or lanyards.
Shoelace Locks: “No-tie” magnetic shoelace closures.
Bag Hardware: Drawstring closures on backpacks.
Ordering Guide: Critical Dimensions
To quote this complex part, we usually need a 3D File (STEP/IGES) or a drawing specifying:
1). Outer Dimensions: Length x Width x Total Height.
2). Hole Dimensions: Length x Height of the oval opening.
3). Step Detail: How high is the raised platform? What are its L x W dimensions?
4). Coating: “Gunmetal / Black Nickel” (as shown) or Standard Silver?
