Precast Concrete Formwork Fixed Magnetic Box

Jan. 10, 2020

Today, the supplier of Precast Concrete Magnet will introduce the relevant knowledge of template magnets.


1. Composition

It is assembled by high-performance permanent strong magnetic NdFeB magnetic components, spring screw connection accessories, stainless steel 201 or 304 buttons, and housing assembly.


2. Working principle

Using the adsorption force between the NdFeB magnetic core and the steel mold table, it is transmitted to the stainless steel button switch through the connecting screw to open and close the magnetic box. Single or double side bayonet design, can be directly clamped on the L-shaped angle steel edge mold, with 8.8 grade high strength on both sides

Adjust the fastening screws to directly press down and fix the steel side mold, thereby strengthening the connection between the magnetic box and the angle steel, and effectively preventing the mold from being displaced.


3. How to use

When using, move the Shuttering Magnet Box to the appropriate position that needs to be fixed, and press the button to make the magnetic core tightly adhere to the steel mold table. At the same time, the bayonet clamps the steel side mold and tightens the side screw. Or complete the tightening and installation through other connecting accessories and pressure plates.

When the production of the component is completed, it is necessary to borrow a professional magnetic box crowbar, pry up the button, and release the magnetism of the magnetic box to complete the disassembly or displacement of the magnetic box.

4. There are two main connection methods between the magnetic box and the steel mold table: high-strength fastening screws are directly pressed down and fixed by extension plate


5. Performance characteristics

Stainless steel casing, super corrosion resistance, greatly extend the life of the magnetic box.

High-performance neodymium-iron-boron magnetism, strong suction, can be firmly fixed on the steel mold table to prevent side mold displacement. In addition, because neodymium-iron-boron material is a permanent strong magnet, it can be used permanently in principle without demagnetization.

Filling between the magnet and iron parts by using stainless steel steel sleeve or epoxy glue, effectively protects the magnet from magnetic loss due to collision and corrosion.


6. Specifications

The suction power varies from 450 to 2100kg, and the best matching magnetic box can be customized according to the actual mold needs.


7. Application

Tong is used for most molds, such as steel molds, aluminum molds, and wooden edge molds of plywood. It is placed on the steel mold table to produce various precast concrete components. It is widely used in the production of prefabricated staircases, exterior wall panels, interior wall panels, and balcony.


8. Precautions for use:

The tightening nut cannot be adjusted down, otherwise, the magnetic box body is opened too much and the contact surface is too large, which causes insufficient adsorption and causes side displacement.

The surface of the steel mold on which the magnetic box is placed needs to be flat, and it must be cleaned before each use. There must be no concrete residue or other particles, so as not to affect the close bonding of the magnetic core and the mold table, and affect the fixing strength.


The magnetic core contact surface must be cleaned before and after the magnetic box is used, and no concrete and iron filings can stick to it, which affects the adsorption force.


Clean the concrete adhering to the joint frequently and apply oil, and regularly add oil to the position of the guide rod to ensure the smooth opening and closing of the magnetic core.


It is forbidden to hit the joint with a hard object such as a hammer, or fall freely on the surface of steel, otherwise the strong adsorption force of the magnetic core itself may damage the box and affect the use, and may even cause the magnetic core to be misaligned and damage the magnetic box.


The above is the information about the template magnet introduced by the manufacturer of Magnetic Chamfer Strip. I hope it can help everyone.
