Magnetic Recess Former: Definition and Technical Analysis

October 29, 2024


 

Definition

 

Magnetic recess former, also known as magnetic steel recess former, is an extremely efficient and accurate device designed for the construction and prefabricated component production fields to locate and fix lifting anchors. HULK Metal's magnetic recess former products focus on quickly and accurately locating lifting anchors to meet the stringent requirements of modern construction for safety, efficiency, and precision. It not only facilitates the construction of recesses on steel formwork but also allows the lifting anchor to be flexibly changed during the production process, greatly improving work efficiency. The magnetic recess former can be firmly attached to the steel formwork without drilling. This non-destructive operation method extends the service life of the formwork and optimizes the process.

 

Composition


HULK Metal can provide magnetic recess formers with different specifications of 1.3t, 2.5t, 5t, and 10t to ensure that different load requirements are met. Each model has a clear load mark for quick identification on site, ensuring that operators can easily identify each load level during assembly and use, enhancing construction efficiency and safety.

 

Main materials and composition


High-performance neodymium iron boron (NdFeB) magnets:

 

The core magnetic component uses NdFeB magnets, which have extremely high adsorption and stability. NdFeB is currently one of the strongest permanent magnetic materials, which enables the groove former to be stably adsorbed for a long time in harsh construction environments to ensure accurate positioning.

 

Common magnets in the market


The common magnets in the market are mainly the following:

 

NdFeB magnet: This is currently one of the strongest permanent magnetic materials. It has extremely high magnetic energy product and coercive force, and is widely used in electronics, motors, medical equipment, aerospace and other fields.

 

Samarium cobalt magnet: It has good high-temperature resistance and can still maintain good magnetism in high-temperature environments. It is often used in aerospace, military, high-temperature motors and other occasions with high requirements for magnetism and temperature.

 

Alnico magnet: It has high remanence and good temperature stability, but relatively weak magnetism. It is commonly used in instruments, sensors, etc.

 

Ferrite magnet: It is cheap and has good anti-demagnetization performance. It is mostly used in products such as speakers, toys, and motors.

 

Rubber magnet: It is flexible and can be processed into various shapes. It is often used in refrigerator magnets, stationery, advertising displays, etc.

 

Bonded NdFeB magnet: It is made of NdFeB magnetic powder mixed with materials such as resin and has certain processability. It is used in some small motors and electronic products.

 

High-strength steel:

 

As precast concrete accessories, steel supports the magnet and effectively protects it from external impact. At the same time, the selection of steel and structural design optimizes the durability and structural strength of the Magnetic Recess Former to adapt to high-intensity construction environments.

 

Surface treatment (galvanized anti-corrosion):

 

All Magnetic recess former steel shells are galvanized to ensure long-term corrosion resistance. The galvanized layer prevents moisture and corrosive substances from corroding the steel, further extending the service life of the equipment.

 

Sealing elements:

 

HULK Metal's magnetic recess former is equipped with a rubber seal to prevent concrete from entering the recess during pouring. In particular, when applying double-headed top pin anchors, no seal is required, which further simplifies the operation steps.

 

Technical specifications:

 

Maximum operating temperature:

 

The standard maximum operating temperature is 80℃, and customized temperature limits can be provided according to customer needs to ensure excellent magnetism and stability under high-temperature conditions.

 

Appearance treatment:

 

The magnetic frames are all zinc-plated to further enhance the anti-corrosion performance, and rubber coating options are provided to ensure the best anti-corrosion effect.

 

Features

 

Accurate and efficient positioning and fixing

 

HULK Metal's Magnetic recess former uses extremely powerful neodymium iron boron magnets. This high suction characteristic ensures the accuracy and stability of the product when positioning the lifting anchor. Compared with traditional rubber recess formers, the Magnetic recess former can be firmly adsorbed without drilling holes in the template. This non-invasive fixing method reduces the wear on the template and extends the service life of the steel template. The product is suitable for repeated use, reducing the overall cost.

 

Modular design, improve flexibility

 

Each Magnetic recess former of HULK Metal adopts a modular design, which can be flexibly assembled according to different project requirements and adapt to various complex construction scenarios. On-site workers can easily adjust the position of the equipment without the need for bolts, welding, and other fixing methods, which significantly shortens the construction time of the project.

 

Non-destructive formwork, strong durability

 

Since the magnetic recess former does not need to drill holes in the formwork, structural damage to the steel formwork is avoided. The product's galvanized anti-corrosion treatment and surface coating design enable it to be reused in harsh environments. Actual tests show that HULK Metal's magnetic recess former products can withstand at least 3,000 cycles of use while maintaining stable performance.

 

Load identification mark to improve safety

 

Each product is equipped with a clear load mark, allowing construction personnel to quickly identify and distinguish magnetic recess formers of different specifications, thereby ensuring that safety regulations are met during installation and use, and reducing the possibility of human error.

 

Application scenarios

 

Magnetic recess former is mainly used in the following scenarios of prefabricated component production and construction:

 

Production of prefabricated concrete components

 

In prefabricated concrete components that require the use of lifting anchors, magnetic recess formers can quickly and accurately locate lifting anchor points, which is suitable for mass production of large components such as wall panels, floors and columns.

 

Lifting and positioning in construction projects

 

In construction projects, the use of magnetic recess formers can accurately arrange to lift anchor points at different locations, providing safety guarantees for the lifting of prefabricated components of high-rise structures.

 

Assembly of large components:

 

In the assembly of components of complex structures, magnetic recess formers can adapt to frequent lifting and positioning needs, and their high reusability reduces equipment costs during construction.

 

Why choose HULK Metal as your magnetic recess former supplier in China?

 

Excellent durability

 

HULK Metal's magnetic recess former uses high-quality neodymium iron boron magnets and high-quality steel and undergoes strict surface anti-corrosion treatment so that it can maintain stable performance for a long time in harsh environments. Its anti-corrosion treatment ensures that the product's service life in humid, acidic, or alkaline environments is significantly extended, adapting to the stringent requirements of the construction and industrial fields.

 

Convenient operation

 

HULK Metal's traditional rubber recess former requires a mold hole to be set on the template to install the anchor bolt, while the magnetic recess former only needs to complete the positioning and fixing of the anchor point through magnetic adsorption. It reduces the complexity of installation, reduces the difficulty of installation for workers, and optimizes the process.

 

High stability and safety guarantee

 

The high-strength NdFeB magnet can provide stable adsorption force at any angle and position so that the lifting anchor maintains extremely high reliability during positioning and fixing. At the same time, the design with load marking enables operators to quickly identify equipment specifications, avoid misoperation, and improve the overall safety of construction.

 

Economic and environmental protection

 

The HULK Metal magnetic recess former can be reused more than 3,000 times. This high reusability not only reduces the equipment procurement cost of construction companies but also effectively reduces waste generation, which is in line with the concept of sustainable development and environmental protection.
