China Top Magnetic Door Catch Factories & Exporter

For standard MDF or particleboard wardrobe doors (height 1800mm–2400mm, mass 12–20kg), a single top-mounted magnetic catch requires a holding force between 8kg and 10kg (approx. 78N to 98N). For solid hardwood doors prone to seasonal bowing, dual installations (one at 100mm from top, one at 100mm from bottom) delivering 6kg each provide balanced stabilization without placing excessive strain on hinge pins during manual opening.

Permanent demagnetization is primarily triggered by severe thermal exposure or mechanical impact shock. We use high-grade NdFeB magnets stabilized with Dysprosium (Dy) additives capable of handling sustained temperatures up to 120°C without flux decay. In addition, our polymer and brass encapsulated structures buffer physical impacts between the magnetic core and counter strike plate.

For extreme maritime environments, standard zinc plating (3–5 microns) fails within months. Foshan EHOME recommends either full encapsulation within SUS316 grade stainless steel housings or advanced multi-layer finishes consisting of copper base plating + semi-bright nickel + bright nickel + micro-porous chrome (total thickness ≥ 18 microns), certified to endure over 240 hours of neutral salt spray testing under ISO 9227 standards.
