Overview of Magnetic Holding Systems Magnetic holding systems use magnetic force to hold, retain, mount, position, suspend, or secure parts in products or mechanical structures. They are not limited to one specific magnet type or one standard product category. Some magnetic holding systems are as simple as single magnets used to hold covers in place,…
Pot magnets are widely used to mount, position, suspend, secure and retrieve components in industrial equipment. Their compact construction can provide high holding force while offering convenient mounting options such as countersunk holes, internal threads, external threads, hooks and threaded studs. However, choosing a pot magnet based only on its advertised pull force can lead…
Overview of Salt Spray Test Salt spray test, also called salt fog test, exposes samples to a controlled corrosive atmosphere inside a test chamber. In a neutral salt spray test, a sodium chloride solution is atomized into fine mist and continuously sprayed under controlled temperature and humidity conditions. The purpose of the test is to…
Magnetic holding under vibration is different from static magnetic holding in ideal test conditions. Holding magnets may show high pull force on clean, flat, and thick steel plates, but real industrial environments often involve vibration, impact, coatings, corrosion, uneven contact, air gaps, and changing load directions. For this reason, magnetic holding under vibration should not…
Magnetic holding force is one of the most important reference values when selecting magnetic bases, rubber coated magnets, and other magnetic holding products. However, this value should not be treated as the guaranteed working load in every application. In real working conditions, magnetic holding force can change significantly. The actual performance depends on the steel…
Overview of Magnetic Shielding Magnetic shielding is a method used to control how magnetic fields spread in space. In many cases, it does not completely block a magnetic field like a wall blocks light. Instead, it provides an easier path for magnetic flux, guiding part of the magnetic field through a suitable material and reducing…
Overview of Air Gap in Magnetic Holding Systems Air gap is a basic but often underestimated factor in magnetic systems. It refers to the non-magnetic distance or layer between magnets and the objects they need to attract, hold, sense, drive, or interact with. In practical use, this gap is not always only air. It may…
Overview of Magnetic Permeability Magnetic permeability indicates how readily a material can carry magnetic flux. In simple terms, a material with high magnetic permeability can provide an easier path for magnetic flux, while materials with very low permeability do not guide magnetic flux effectively. In magnetic holding products, this concept is important because the magnet…
Overview of Overmolded Magnets Overmolded magnets are magnetic components made by molding rubber, plastic, elastomer, silicone, or another suitable material around one or more permanent magnets or magnetic assemblies. Instead of using bare magnets alone, the surrounding material can provide surface protection, friction, impact resistance, insulation, positioning features, or a more application-ready structure. At WZ…
