Shopping tips

Magnetic grates serve for precise separation of metal contaminants from bulk raw materials. They are also used in recycling, ceramics, and the chemical industry. They protect machines from failure and ensure high quality of the final product.
For basic protection against so-called "tramp iron" (coarse iron), the standard model is sufficient. If you need to remove microscopic filings, iron oxides, or stainless steel after mechanical processing, choose High Power. In the food industry, the strongest version (10kGs+) is often required.
Cleaning involves manually removing collected contaminants from the surface of magnetic rods. Since the magnets are very strong, filings stick firmly - you can use adhesive tape to remove them (tape method). We recommend frequent checks of the filter's contamination status, e.g., once per work shift.
We can produce a sieve perfectly matched to your hopper or pipeline. We design multi-level separators for specific machines and capacities. We guarantee solidity, TIG welds, and material certificates for steel.
We use highest quality stainless steel, safe for food products. High quality surface finish facilitates washing and disinfection. We help in meeting quality and audit standards in production plants.

Pros as well as cons of neodymium magnets.

In addition to their magnetic capacity, neodymium magnets provide the following advantages:

  • They retain full power for nearly 10 years – the loss is just ~1% (based on simulations),
  • Neodymium magnets remain highly resistant to loss of magnetic properties caused by external field sources,
  • A magnet with a shiny gold surface has better aesthetics,
  • The surface of neodymium magnets generates a concentrated magnetic field – this is a distinguishing feature,
  • Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
  • Thanks to flexibility in shaping and the ability to customize to unusual requirements,
  • Significant place in high-tech industry – they find application in hard drives, electric motors, precision medical tools, as well as technologically advanced constructions.
  • Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which enables their usage in miniature devices

Cons of neodymium magnets: application proposals

  • They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only shields the magnet but also improves its resistance to damage
  • We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
  • When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation and corrosion.
  • We recommend a housing - magnetic holder, due to difficulties in realizing threads inside the magnet and complicated shapes.
  • Possible danger resulting from small fragments of magnets are risky, in case of ingestion, which gains importance in the context of child health protection. Furthermore, small elements of these products are able to complicate diagnosis medical in case of swallowing.
  • With mass production the cost of neodymium magnets is a challenge,

Maximum lifting capacity of the magnetwhat it depends on?

The load parameter shown represents the peak performance, measured under laboratory conditions, specifically:

  • using a sheet made of high-permeability steel, acting as a circuit closing element
  • whose transverse dimension is min. 10 mm
  • with an ideally smooth contact surface
  • under conditions of ideal adhesion (surface-to-surface)
  • for force applied at a right angle (pull-off, not shear)
  • in stable room temperature

Impact of factors on magnetic holding capacity in practice

In practice, the actual holding force is determined by many variables, presented from the most important:

  • Air gap (betwixt the magnet and the plate), because even a very small clearance (e.g. 0.5 mm) results in a drastic drop in force by up to 50% (this also applies to paint, corrosion or debris).
  • Force direction – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet holds significantly lower power (often approx. 20-30% of nominal force).
  • Metal thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of converting into lifting capacity.
  • Chemical composition of the base – mild steel attracts best. Alloy admixtures lower magnetic permeability and holding force.
  • Plate texture – smooth surfaces guarantee perfect abutment, which improves force. Uneven metal reduce efficiency.
  • Heat – neodymium magnets have a sensitivity to temperature. At higher temperatures they lose power, and in frost gain strength (up to a certain limit).

* Lifting capacity was determined by applying a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, whereas under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a small distance {between} the magnet and the plate lowers the load capacity.

Precautions when working with NdFeB magnets

Protective goggles

Protect your eyes. Magnets can explode upon violent connection, launching shards into the air. Eye protection is mandatory.

Metal Allergy

A percentage of the population have a contact allergy to Ni, which is the typical protective layer for NdFeB magnets. Frequent touching can result in dermatitis. We suggest use protective gloves.

Adults only

NdFeB magnets are not intended for children. Accidental ingestion of several magnets may result in them connecting inside the digestive tract, which poses a severe health hazard and requires immediate surgery.

Conscious usage

Use magnets with awareness. Their powerful strength can shock even experienced users. Stay alert and respect their power.

Hand protection

Big blocks can crush fingers in a fraction of a second. Never place your hand between two strong magnets.

Heat warning

Keep cool. Neodymium magnets are sensitive to temperature. If you require operation above 80°C, ask us about HT versions (H, SH, UH).

Threat to navigation

A strong magnetic field disrupts the operation of magnetometers in smartphones and GPS navigation. Keep magnets close to a device to avoid breaking the sensors.

Cards and drives

Data protection: Strong magnets can damage data carriers and delicate electronics (pacemakers, medical aids, timepieces).

Mechanical processing

Powder generated during cutting of magnets is self-igniting. Do not drill into magnets unless you are an expert.

Medical implants

For implant holders: Strong magnetic fields disrupt medical devices. Maintain at least 30 cm distance or ask another person to handle the magnets.

Caution!
