Shuttering Magnet Box

The Shuttering Magnet Box, also known as concrete formwork magnetic box, is a switchable high-strength magnetic fixing device specially developed for precast concrete construction. Integrated with premium NdFeB magnetic cores and thickened carbon steel protective housing, it serves as a modern replacement for traditional bolt fastening and clamp fixing methods. Designed with a reliable on/off button switch structure, it delivers strong, stable magnetic adsorption force to firmly fix steel and wooden formworks on steel casting tables, ensuring accurate positioning during concrete pouring and molding processes.
Featuring a user-friendly one-touch control design, the magnet box can be quickly activated and deactivated without complex tools or tedious installation steps. Pressing the button enables strong magnetic attraction to lock the shuttering tightly, while simple prying releases the magnetic force for rapid disassembly. The internal magnetic shielding structure concentrates magnetic energy on the working surface, maximizing holding force and avoiding stray magnetic interference. Its robust fully welded steel casing resists concrete impact, vibration, dust and mortar corrosion, ensuring stable performance in harsh construction environments.
Available in multiple specifications with adjustable holding force ranging from 450kg to 3000kg, the shuttering magnet box adapts to various precast component production scenarios. It effectively improves formwork assembling precision and construction efficiency, reduces manual labor and material waste, and eliminates traditional fixing defects. Durable, low-maintenance and highly reusable, it has become a standard essential fixture for standardized, high-efficiency precast concrete manufacturing in the construction industry.
