Magnetic recess former is one of the most widely used precast concrete magnet. It is normally co-used with foot anchor in metal mold wall to get firm fixation so that the foot anchor can stay still in position and people get the precast part in the shape as they have expected. By using magnets there is no need to drill holes so that the mold table could have a longer life. It is simple and convenient to use.
First, put the foot anchor into the hole of the magnetic recess former;
Second, attach the magnetic recess former on the metal mold wall at requested positions.
Third, pour the concrete, vibrating the mold table and wait until the it is hardened.
Forth, de-mold and remove the steel mold. Job done and you can find the foot anchor fixed firmly in the hemisphere shaped hole in the concrete precast part.
2 Types Recess Former Magnets for Foot Anchor
Based on our regular version we made the pro version——optimization on the structure of these foot anchors by design a steel plate upon the bottom magnet, so that they produce even higher force (50%~300%+ higher). More importantly, the cost of these pro version foot anchors did not increase that much and this means that customers just need to pay almost the same price to get higher force foot anchors.
These magnetic former are zinc plated for corrosion resistance or made with a rubber coating. They are available in load groups 1.3Ton, 2.5Ton, 5Ton, 10Ton.
1). Steel Recess Former Magnets
Steel Recess Former Magnets also known as NdFeB Recess Former Pro for Foot Anchor.
There are available diameters:
D60mm(150KG holding force) for 1.3t anchor;
D74mm(190KG holding force) for 2.5t anchor;
D94mm(230KG holding force) for 5.0t anchor;
D118mm(360KG holding force) for 10.0t anchor.
Normally the steel magnetic recess former is used together with a T anchor (also called double head pin anchor) and rubber ring.
In application, the T Anchor with rubber ring is firstly insert into the hole of the magnetic former, then the magnet recess former will firmly fix on the metal mold for concrete pouring.
2). Rubber Coating Recess Former Magnets
Rubber Coating Recess Former Magnets also known as Rubberized magnetic recess formers.
Which are available in diameters:
D66mm(100KG holding force) for 1.3t anchor;
D84mm(190KG holding force) for 2.5t anchor;
D104mm(300KG holding force) for 5.0t anchor;
D125mm(400KG holding force) for 10.0t anchor.
In application, The Rubberized magnetic former is different from that of steel magnetic former because of the elastic nature of the rubber itself.
Benefits of Pro Version Foot Anchor Magnetic Recess Former:
Magnetic recess former is a modern way for fixing and fastening. Which we can get rid of the traditional way of using fasteners, pins as that usually spend a long-time labor-consuming in hole-drilling, fixing or taking off. Further, drilling holes will make the metal mold table and formers less durable. Using magnetic recess former, which produce strong holding force as a result of the magnet inside and optimized magnetic circuit design, saves huge amount of time. That’s why customers in the precast industry increasingly switch to this fast solution.
1) Reduce the complexity and time of the installation and demolding.
2) No need for drilling and welding, no damage to the metal mold wall.
3) Repeated use, strong force even after a long-time use.
4) Steel plate upon the bottom protect inside NdFeB magnet from corrosion resistance
4) Customized dimension to suit your anchor.
