Rubber Coated Magnets

The Introductions to Rubber Coated Mounting Magnets

Rubber Coated Magnet, also named as rubber covered neodymium pot magnets & rubber coated mounting magnets, is one of the most common practical magnetic tool for indoors & outdoors. It’s generally regarded as a typical sustained magnetic solution, especially for storage, hanging, mounting and other fixing functions, which require powerful attraction force, waterproof, durable lifetime, anti-rusty, free of scratches and slide resistance. In this article, let’s try to figure out the component, characteristics, features and applications of rubber coated magnets family together.

1. What is rubber coated magnet?

Rubber coated magnets are normally composed with super powerful permanent sintered neodymium (NdFeB) magnet, backup steel plate as well as durable rubber (TPE or EPDM) covering. With the characteristics of emerged neodymium magnets, it could afford powerfully strong adhesive forces in very small size to use.  Several pieces small round or rectangular magnets will be mounted into the backup steel plate with glue. A magic multi-poles magnetic circle and steel plate basement will be generated from “N” and “S” pole of magnet groups through each other. It brings out 2-3 times of strengths, compared to the regular magnets by themselves.

Regarding the backup steel plate basement, it’s stamped into shapes with pressing holes for positioning and installing magnets. Also it requires kind of glues to enhance the connection of magnet and steel bed.

To provide a durable, stable and multi-shaped protection for inside magnets and steel plate, the Thermo-Plastic-Elastomer material is chosen to use under the processing of vulcanization or injection molding technology. The  injection molding technology is much more conventional  in the rubberized procession, due to its high productivity, material and manual cost saving and flexible color options, rather than vulcanization technology.  However, vulcanization technology is preferably taken for those operational environment, featuring superior durability of wearing quality, weather ability, seawater corrosion resistivity, oil proof, broad temperature compatibility, such as wind turbine applications.

 2.  Categories of Rubber Coated Magnets Family

With benefits of rubber shapes flexibility, the rubber covered mounting magnets could be in various shapes as round, disc, rectangular and irregular, according to users’ demand.  The internal/external thread stud or flat screw as well as colors are optional for production.

1) Rubber Coated Magnet with Internal Screwed Bush

This screw bushing rubber coated magnet is ideal for inserting and attaching equipment to the targeted ferrous substance where it is crucial to protect the paint surface from damage. A threaded bolt will be inserted into this screwed bushing, rubber coated, mounting magnets. The screwed bush point will also accept a hook or handle for hanging ropes or manual operating. Several of these magnets bolted onto a three-dimensional promotional product or to decorative signage can make it suitable to be displayed on cars, trailers or food trucks in a non-permanent and non-penetrative way.

2) Rubber Coated Magnet with External Threaded Bush/Threaded Rod

3) Rubber Coated Magnet with Flat Screw

4) Rectangular Rubber Coated Magnet with Single/Double Screw Holes

5) Rubber Coated Magnet with Cable Holder

6) Customized Rubber Coated Magnets

3.  The Main Advantages of Rubber Coated Magnets

(1) Diverse optional rubber coated magnets in different shapes, working temperature, adhesive forces as well colors on the demands.

(2)  The special design brings out 2-3 times of strengths, compared to the regular magnets by themselves.

(3) Rubber coated magnets features a superior waterproof, durable life time, anti-rusty, free of scratches and slide resistance, compared to regular magnetic assemblies.

4. The Applications of Rubber Coated Magnets

These rubber coated magnets are functionally used to create a connection joint for the items to the ferrous plate or wall, mounted on the steel surface of vehicles, doors, metal shelves and machine types with sensitive touching surfaces. The magnetic pot can create a permanent or temporary fixing point avoid a borehole and damage the painted surface.

The fixing points are also used to fix sheets of ply or similar protecting openings in buildings under construction from thieves and inclement weather, attached to metal door and window frames. For truckers, campers and emergency services, these devices effect a secure fixing point for temporary containment lines, signs and flashing lights while protecting highly finished painted vehicle finishes via the rubber coating.

In some critical environment, like Wind Turbine nearby seawater, it requires seawater corrosion resistivity and broad temperature compatibility strictly for all the working equipment. In this case, the rubber coated magnets are perfect to use for fixing bracket, equipment on the wind turbine tower wall, instead of bolting and welding, like lighting, ladder, alert labels, pipe fixing.
