Magnetic Recess Former – D118 | M12 Thread

The Magnetic Recess Former – D118 | M12 Thread is a reusable magnetic recess-forming and positioning component designed for applications where a recess or locating point needs to be formed against compatible ferromagnetic steel formwork or mould surfaces. Featuring a 118mm diameter magnetic base and an M12 threaded connection, this magnetic former provides a practical method of positioning components during compatible precast concrete, formwork and manufacturing processes.

The integrated magnetic system allows the recess former to attach to suitable steel surfaces without requiring permanent drilling or welding into the supporting formwork. Its M12 threaded connection provides a defined mechanical interface for compatible threaded components or installation equipment.

This 118mm magnetic recess former is particularly suited to precast concrete production, steel formwork, mould systems and industrial manufacturing applications where repeatable positioning and removable magnetic attachment are required.

What Is a Magnetic Recess Former?

A magnetic recess former is a magnetic positioning component used in compatible formwork and mould systems to help create or locate a defined recess during a production process.

Rather than permanently fastening the former to suitable steel formwork, magnetic attraction can hold the component in position during setup and production.

After the process is complete, the former can be removed and potentially reused for subsequent production cycles.

This makes magnetic recess formers useful where repeatable positioning, fast setup and reusable tooling are important.

118mm Diameter Magnetic Former

The recess former has a specified diameter of 118mm.

This broad magnetic footprint is designed to provide contact with compatible ferromagnetic steel formwork or mould surfaces.

Before installation, confirm that the 118mm diameter is compatible with:

• The intended formwork
• Required recess geometry
• Surrounding components
• Available installation space
• The complete precast or moulding system

The 118mm measurement should not be interpreted as the finished recess diameter unless this has been independently confirmed for the specific application.

M12 Threaded Connection

The integrated M12 thread provides a mechanical connection point for compatible threaded components.

Depending on the design of the complete system, an M12 connection may be used with compatible:

• Bolts
• Threaded studs
• Installation tools
• Positioning components
• Fixtures
• Recess-forming accessories
• Custom equipment

Correct thread engagement should be confirmed before use.

Avoid overtightening threaded components or applying excessive leverage that could damage the magnetic assembly or cause unexpected detachment from the supporting steel.

Magnetic Attachment to Steel Formwork

The magnetic base is designed to attach to suitable ferromagnetic steel surfaces, allowing the former to be positioned without permanently modifying the supporting steel in compatible applications.

Potential advantages include:

• Faster positioning
• Removable attachment
• Repositioning between production runs
• Reduced need to drill steel formwork
• Reduced need for welded attachment points
• Reusable production setups
• Flexible mould configuration

This can make magnetic mounting particularly useful in precast production environments where formwork is repeatedly reconfigured.

How Does a Magnetic Recess Former Work?

In a typical compatible application:

1. The steel formwork or mould surface is prepared and cleaned.
2. The magnetic recess former is positioned at the required location.
3. The magnetic base attracts to the ferromagnetic steel surface.
4. The M12 connection is integrated with the compatible component or tooling as required.
5. The former remains positioned during the applicable production process.
6. Following completion, the former can be removed, cleaned and prepared for reuse.

The exact installation procedure should always follow the requirements of the complete formwork, lifting-anchor or precast system in which the former is being used.

Precast Concrete Applications

Magnetic recess formers can be particularly useful in precast concrete manufacturing, where repeatable positioning of components within steel moulds is important.

Potential applications include:

• Precast wall panels
• Concrete structural elements
• Concrete slabs
• Beams
• Custom precast products
• Recessed connection points
• Production moulds
• Reusable steel formwork

Compatibility with the specific concrete component, anchor system and formwork design should be confirmed before use.

Magnetic Holding Performance

The holding performance of a magnetic recess former depends on the complete installation.

Important factors include:

• Steel thickness
• Steel composition
• Surface flatness
• Available contact area
• Paint or coatings
• Rust
• Concrete residue
• Dirt and contamination
• Air gaps
• Applied force direction
• Vibration
• Impact
• Leverage
• Production conditions

For strongest practical attraction, the magnetic working surface should make close, flat contact with clean and sufficiently thick ferromagnetic steel.

No specific magnetic pull force has been supplied for this product, so holding capacity should not be inferred from the 118mm diameter.

Surface Preparation

Clean contact surfaces are important for reliable magnetic attachment.

Before positioning the former:

• Remove loose concrete residue
• Remove excessive rust or contamination
• Clean away ferrous particles
• Check the magnetic contact surface
• Ensure the target steel is sufficiently ferromagnetic
• Maximise flat contact between the former and steel

Paint, coatings, concrete residue and other materials between the magnet and steel create an air gap that can reduce magnetic attraction.

Reusable Formwork Component

A key benefit of magnetic formwork equipment is the ability to remove and reuse components between production cycles.

After use:

• Remove the former carefully
• Clean away concrete residue
• Inspect the magnetic contact surface
• Check the M12 thread
• Inspect the assembly for damage
• Store appropriately before the next production cycle

Regular inspection can help identify wear or damage before the component is returned to service.

Installation Considerations

Before using the Magnetic Recess Former:

• Confirm the 118mm diameter suits the intended application
• Confirm compatibility with the complete recess or anchor system
• Verify the M12 threaded connection
• Check the target surface is ferromagnetic
• Clean both contact surfaces
• Ensure the former sits correctly against the steel
• Consider forces generated during the production process
• Avoid excessive leverage on threaded components
• Inspect the former before each production cycle

The complete installation should be assessed according to the requirements of the precast or formwork system.

Please Note

This product is specified as a Magnetic Recess Former with a 118mm diameter and M12 thread.

No specific pull force, magnetic material or grade, overall height, recess dimensions, thread depth, construction material, coating, dimensional tolerance or maximum operating temperature has been supplied and these specifications should not be assumed.

The 118mm diameter describes the supplied magnetic recess former and should not automatically be interpreted as the dimensions of the finished concrete recess. Confirm the required recess geometry with the applicable precast, anchor or formwork system before use.

Actual magnetic holding performance depends on steel thickness and composition, surface condition, contact area, coatings, contamination, air gaps, load direction, vibration and leverage.

Where this component forms part of a lifting-anchor, structural or safety-critical precast system, compatibility and installation requirements must be verified against the specifications of the complete engineered system. The magnetic recess former itself should not be treated as lifting equipment or as establishing the load rating of an associated lifting anchor.

Strong magnetic equipment should be handled carefully and kept away from pacemakers and other medical implants, magnetic storage media and sensitive electronic equipment.
