How to Store Shuttering Magnets Safely in Precast Plants

Introduction

Shuttering magnets are used repeatedly in precast concrete production, so proper storage is important for maintaining their performance and service life. Concrete residue, moisture, impact, and improper stacking can damage the housing, switch mechanism, and bottom contact surface.

For precast plants, safe storage is part of daily equipment management. It helps maintain a stable holding force, improves worker safety, reduces repair costs, and keeps magnets ready for the next production cycle.

Clean Shuttering Magnets Before Storage

Cleaning is the first step for safe shuttering magnet storage. After each use, concrete residue, cement slurry, dust, and metal debris should be removed in time, especially from the bottom contact surface. This area directly affects the real holding force of the magnet. Dirt or hardened concrete can create air gaps and reduce magnetic performance during the next use.

When cleaning, avoid sharp tools, heavy grinding, or rough impact to prevent surface damage. Scrapers, soft brushes, or suitable cleaning tools are better choices for daily maintenance.

The switch area should also be kept clean to prevent cement slurry or small particles from causing jamming. Before storage, make sure the magnet is fully dry. This helps with inspection, safer storage, and longer service life.

Keep Magnets Dry and Away from Moisture

In precast plants, shuttering magnets are often exposed to water, cement slurry, or humid environments. If they are stored before being properly dried, corrosion may occur on the steel housing, bolts, switch components, and bottom contact surface, affecting service life and operation performance.

Before storage, surface residue should be removed, and the magnets should be kept dry. Do not place magnets directly on wet floors or near drainage areas, as long-term moisture exposure may damage the surface coating.

It is recommended to store magnets on pallets, metal racks, or in dedicated storage boxes. This helps isolate them from ground moisture and reduces impact damage. Large plants can also set up separate storage areas to make different shuttering magnet models easier to manage and access.

Avoid Random Stacking and Heavy Impact

Shuttering magnets should be handled as precision production tools, not ordinary steel blocks. Dropping, throwing, or stacking too many magnets directly on top of each other may deform the steel housing, damage the internal magnetic system, or affect the switch mechanism. Even if the magnet still looks usable, hidden damage can reduce its reliability in precast production. Whenever possible, magnets should be stored on shelves, pallets, or dedicated storage racks and kept separated from each other to prevent collision and pressure damage.

Store Magnets Away from Sensitive Equipment

Keep Away From Electronic Devices

Avoid storing shuttering magnets near computers, control panels, phones, tablets, or electrical cabinets. Strong magnetic fields may interfere with certain electronic components or cause operational issues.

Avoid Measuring Instruments And Sensors

Precision measuring tools, sensors, scales, and calibration equipment should be kept at a safe distance. Even minor magnetic interference may affect measurement accuracy, which can lead to production errors.

Separate Magnets From Magnetic Cards And Data Devices

Do not place shuttering magnets near magnetic cards, ID cards, storage devices, or similar items. Magnetic exposure may damage stored information or reduce its reliability.

Mark Storage Areas Clearly

Precast plants should set up a dedicated magnetic storage area with clear warning signs. Workers can then identify safe zones quickly and avoid placing sensitive tools or devices nearby.

Protect the Bottom Contact Surface

The bottom contact surface directly affects how well the shuttering magnet fits against the steel casting table and determines the stability of its actual holding force. If concrete residue, cement slurry, rust, oil, or metal particles remain on the surface, small air gaps may form, reducing the magnet's working force and increasing the risk of formwork movement.

When storing shuttering magnets, avoid dragging them across rough floors, stacking them carelessly, or exposing them to impact. It is better to place them on clean racks, pallets, or protective pads to reduce wear on the bottom contact surface.

Before reuse, check whether the contact surface is flat, clean, and free from buildup, deformation, or uneven wear. Keeping the bottom surface in good condition helps maintain a stable holding force, improve formwork fixing accuracy, and extend the service life of the shuttering magnet.

Check the Switch Mechanism Before Storage

Before storage, check whether the shuttering magnet switch moves smoothly. Remove concrete slurry, dust, or metal debris around the moving parts to prevent jamming and wear.

If the switch is stuck, do not force it, as this may damage the internal mechanism. Clean, lubricate, or repair the switch when needed. Regular inspection helps keep the magnet safe, easy to operate, and ready for the next production cycle.

Organize Magnets by Model and Force Rating

Classify by Size and Model

Store shuttering magnets according to their size, type, and compatible formwork system. This helps workers quickly find the right magnet for each production task without wasting time searching.

Classify by Holding Force Rating

Magnets with different holding force ratings should be stored separately. For example, light-duty magnets and high-force magnets should not be placed in the same storage box. Using the wrong magnet may lead to insufficient holding force or unnecessary overuse.

Clearly Label Storage Areas

Shelves, pallets, or containers should be clearly marked with the magnet model, holding force rating, and quantity. Clear labels help reduce confusion during busy production shifts.

Create a Regular Inspection Schedule

Check The Magnet Surface Regularly

Inspect the bottom contact surface for concrete residue, scratches, dents, or uneven wear. A clean and flat contact surface is essential for a stable magnetic holding force.

Inspect The Housing And Switch Mechanism

Check for deformation, cracks, loose parts, or stuck switches. If the switch cannot operate smoothly, the magnet should be inspected before being used again.

Watch For Corrosion And Performance Decline

Rust, moisture damage, or a noticeable drop in holding force may indicate poor storage or long-term wear. These magnets should be stored separately for maintenance.

Test Holding Force When Possible

Regular pull-force testing helps confirm whether the magnet still meets production requirements, especially for frequently used models.

Remove Damaged Magnets From Production

Do not continue using magnets with cracked housings, weak holding force, or unsafe switch operation.

Keep Inspection Records

Record inspection dates, problems, repairs, and test results. This helps improve equipment management and extend the service life of shuttering magnets.

Common Storage Mistakes to Avoid

· Storing magnets without cleaning

· Placing magnets on wet floors

· Dropping or stacking magnets roughly

· Mixing different magnet models

· Ignoring damaged housings or stuck switches

· Storing magnets near precision equipment

Conclusion

Proper shuttering magnet storage helps maintain stable performance and extend service life in precast plants. Magnets should be cleaned, dried, protected from impact, stored in an organized area, and inspected regularly. A well-managed storage process reduces equipment damage, improves worker safety, and ensures shuttering magnets remain reliable for repeated production cycles.
