What is precast formwork?

Through the suction action of the magnet , the magnetic formwork is closed contact with the pallet , so that the formwork system that to be formed is fixed. Since the steel shell and the magnet are integral , there will be not movement to ensure that the formwork system is not deform . At the same time , the simple and fast operation of the magnet makes the whole work safer and more stable . With a matching crowbar , the magnet can be pried up and the formwork easily removed from the pallet .

Because the magnet system is located inside the steel shell , the concrete residue or other dirt will not damage the entire formwork system .

With the development of the prefabricated construction industry , magnetic box , insert magnets and other magnetic fixed products have been fully applied in the production process of precast concrete components . The magnetic formwork is embedded magnet chunks inside , compared with the magnet box , it is more convenient for standarder and mass production .

(1) in addition to the influence of magnet performance, another key point of the magnetic box suction is the contact surface of the core and the die. In general, before the magnetic box factory, the surface of the magnetic core will be ground by precision grinder, flatness in 0.01 mm or more. However, in the course of use, because the magnetic switch drives the magnetic core to move up and down, and the magnetic switch is only connected with the middle part of the magnetic core, the middle part of the magnetic core will be uneven with other parts after a long period of use, caused the magnetic box suction greatly reduced. The stainless steel pad is added between magnetic core and magnetic switch in Saixin magnetic box, which increases the contact area between magnetic core and magnetic switch, prevents the inner irregularity of magnetic core and reduces the magnetic box suction.

(2)the Shell is provided with a stiffening plate to prevent external force from striking and deforming. The internal stiffeners are made of 6mm thick steel plate to improve the internal strength of the Shell. All parts of the shell are snap-on design to increase the strength of the connection between the parts. The strength of welds in vulnerable parts is improved and the service life of the Shell is prolonged.

(3)magnetic switch has been thickened to prevents the switch from deforming after long-term use.
