1. General Overview

In today’s industrial and commercial environments, rubber coated neodymium magnets have become one of the most reliable and versatile solutions for mounting, holding, and securing equipment. Compared to traditional bare magnets, these products offer superior performance, enhanced durability, and safer usability across a wide range of applications.

This product line is based on rare earth neodymium magnets (NdFeB), widely recognized for their exceptional strength-to-size ratio. The magnets are encased in a durable black rubber coating, which provides effective protection against scratches, rust, and weather-related damage. At the same time, the design features external or internal threaded studs, countersunk holes, or round bases, making them an excellent choice for LED work lights, taxi roof signs, outdoor spotlights, advertising displays, mounting brackets, and industrial fixtures.

We provide multiple configurations of rubber coated pot magnets, including:

• External/Male Thread Rubber Coated Magnets – perfect for quick installation of LED light bars or car roof accessories.

• Internal/Female Thread Rubber Coated Magnets – highly versatile and compatible with a wide range of bolts or screws.

• Countersunk Rubber Base Magnets – designed for seamless mounting with countersunk screws, ideal for signage and display boards.

• Black Round Rubber Coated Magnet Bases – simple yet powerful solutions for multipurpose mounting needs.

By offering different structural designs, customers can select the most suitable model depending on their installation environment and load-bearing requirements.

2. Materials and Manufacturing

2.1 Neodymium Core

At the heart of each unit lies a high-grade neodymium magnet (N35–N52). These rare earth magnets are among the strongest available in the world, capable of generating significant magnetic force even in compact sizes. This ensures stable holding power on steel surfaces, whether for temporary or permanent mounting.

2.2 Rubber Coating Advantages

The black rubber encapsulation is more than just a protective layer – it is a carefully engineered feature with several benefits:

• Scratch Prevention – Protects delicate surfaces such as car roofs, stainless steel panels, or painted boards.

• Waterproof & Rust-Resistant – Creates a barrier against moisture, corrosion, and salt spray, extending product lifespan.

• Enhanced Grip – The rubber coating increases friction, ensuring magnets stay securely in place even under vibrations, wind load, or vehicle motion.

• Noise Reduction – Soft rubber reduces vibration noise compared to bare magnets.

2.3 Thread & Hole Designs

Different thread and hole structures expand the product’s usability:

• External/Male Thread Magnet Mounts – Often used in LED light bar brackets, taxi top signs, and camera rigs.

• Internal/Female Thread Rubber Base Magnets – Provide flexibility for custom bolts, hooks, or eyebolts.

• Countersunk Hole Rubber Magnets – Enable flat installation with flush screws, widely used in signage, displays, and fixtures.

2.4 Precision Manufacturing

Every magnet base is produced through CNC machining and injection molding, ensuring precise dimensions, consistent performance, and strong bonding between the neodymium core and rubber shell.
