First, non-manufacturers

It is possible that you are looking for a middleman, not a direct manufacturer. The price is naturally much higher than the price of the direct manufacturer you are looking for. At present, there is a lot of magnet trade. You can ask for a visit and see if the other party is active. Welcome or find reasons to refuse.

Second, the actual requirement is not clear

Some customers are not sure what material they want for their magnets, causing some salesmen to misplace the material and report the wrong price.

Third, the quality of after sales

The quality of the after-sales will also greatly affect the price of the magnet.

Fourth, the cost is different

We know that the common performance of ordinary NdFeB is also commonly used N35, but at present there are many manufacturers using N33, N28 to impersonate, the price will naturally be much cheaper. Sinoneo magnets want to say that each product is quoted for its reasons, if a company wants to survive, it is impossible to survive the cheap and good quality magnet products.

Divided from the structure, there are two kinds of strong magnetic rods, one is the process equipment connected with other production equipment, such as pipe iron remover, mixed iron remover, etc., the structure is relatively simple; one is the whole machine, such as rotary iron remover, Light powder iron remover. In addition, complete machines with composite functions, such as granulation and iron removal machines, screening and iron removal machines, etc., have appeared on the market.

From the technical function, the magnetic bar has a high, medium and low grade. The magnetic rod iron remover for assembling the magnetic rod with the ferrite magnetic material has the function of removing the ferromagnetic metal foreign matter, and the price is low, which is a low grade.

The magnetic rod is made of rare earth magnetic material, namely neodymium iron boron. NdFeB is divided into different series and grades according to its function. Mid-range iron remover generally uses N48 below NdFeB magnetic material, its field peak is 7000 to 10000 Gauss; Gaussian strong magnetic rod uses N48H, N50 or more magnetic material, the peak value of the table is as high as 12000 Gauss.

Magnetic bars are different from metal detectors. The strong magnetic rod is superior to the latter in that it can remove metal foreign matter in the production process, and the removal method is superior. In order to ensure the safety and quality of products, many large-scale enterprises use both products at the same time.

The selection of strong magnetic rods should be based on the actual and applicable cost requirements. First, it is necessary to determine whether to select process equipment or the whole machine according to the actual conditions of production;

Second, you should choose the grade of the magnetic rod according to the functional requirements. Functional requirements include two aspects – magnetic field strength and removal rate. Export products (such as APIs, food additives) generally require 12000 Gaussian field strength, and the removal rate is related to the number of strong magnetic bars or magnetic plates. The more layers, the higher the removal rate. If you only remove iron debris, you can choose a low-grade iron remover.

Third, According to the shape and fluidity of the material, the magnetic field structure of the iron remover is selected, mainly the magnetic rod and magnetic plate spacing. If the material is very fluid, use a rotating or vibrating magnetic rod.

Fourth, the material flux of the iron remover should be selected according to the production volume.

Fifth, Determine the three-dimensional size of the strong magnetic bar according to the on-site space where the iron remover is installed. Six also consider how the iron separator is connected to other production equipment.

The headache of the manufacturer is that the material is not clean and the product can not pass the quality inspection. This is a common problem.

This is the pain point of the manufacturers mentioned at the beginning of this article. Every time the iron products removed from the purchase can not filter the iron slag, the product can not pass the quality inspection, how to change the situation,so that It can reduce the production cost and quickly solve the problem.

It is necessary to mention the key points, how to find a good magnetic filter bar manufacturer!

Purchasing a strong magnetic bar not only depends on the price, but also on the quality! The low-priced strong magnetic bar, the magnet with the refurbished magnetic material or the magnetic core is not the same size, the strong NdFeB magnet is replaced by the ferrite magnet, which leads to the price of magnetic bar is different on the market.

How do you know the difference between good and bad magnetic bars?

Sinoneo Magnets magnetic bar manufacturers master to give you some suggestions:

First, starting from the appearance, how to weld the two ends of the magnetic bar, whether there is strict welding, can not enter the water, if found to be able to enter the water phenomenon, which means that this magnetic bar is not a good magnetic bar, can not be used.

Second, starting from the magnetic line, holding the magnetic rod to roll a few times in the ground, the magnetic line will come out, then you can use the Gauss meter to measure the magnetic force, confirm if you can meet your requirements.

Third, starting from the size of the specifications, using a special tool to measure the diameter of the strong magnetic bar has not reached the size of the order at the time, the deviation is not serious, these all indicate the strength of the manufacturer and the attitude of doing things.

Once you know this, go and tell your company’s purchasing staff, you have the ideas to reduce production costs and make the materials more pure.

Strong magnetic rod manufacturers: Sinoneo magnets focus on providing filter iron slag solutions, let us help you!

The stainless steel seamless tube and the outer frame form a solid whole through the skilled welding of the workers. It can be installed on the production line or simply placed in a hopper, material box and easily removed and cleaned. The Sinoneo magnetic grate(magnetic grid) is made of materials with a corrosion-resistant surface that meets the cleanliness of food and even pharmaceuticals. Our magnetic grate(magnetic grid) is usually arranged in parallel with a center-to-center spacing of 50mm with a diameter 25mm magnetic bar.
 
The application of magnetic grate(magnetic grid):

Magnetic filter holder (magnetic frame) is mainly used to filter ferromagnetic impurities in powdery, granular raw materials and liquids or slurries. It is widely used in ceramics, electric power, mining, plastics, chemicals, rubber, pharmaceuticals, food, environmental protection, pigments. , dyes, electronics, metallurgy and other industries.

The working principle of magnetic grate(magnetic grid):

The magnetic filter grate(grid) is made of stainless steel tube and high value rare earth alloy NdFeB magnets. And combined on a fixed frame to form a magnetic filter holder. When the iron-containing substance passes, it is attracted by the magnetic rod, and the iron-containing substance is firmly adsorbed on the pipe wall to ensure the integrity of the equipment and the cleanness of the product.

The features of magnetic grate(magnetic grid):

The magnetic frame has no energy consumption and can be installed at any position on the production line that can be in contact with materials. It saves space and is easy to install. It mainly uses rare earth neodymium magnets as magnetic source, good magnetic force, simple structure and long working life. The style,size and shape can be customized according to customer requirements and production conditions.

The magnetic filter frame is mainly used to remove iron impurities from the hopper, feed trough and floor space, which can effectively remove free flowing powder and iron impurities in small particles. The magnetic grate(magnetic grid) has a well-packaged magnetic bar that provides a high-intensity magnetic field to attract iron powder, iron filings, and other magnetically small pieces of metal in the flowing material. It can be installed on the production line or simply placed in a hopper, material box and easily removed and cleaned.

Alnico can be cast into different shapes with various magnetic orientations. The rare earth Sm-Co and NdFeB magnets have high coercivity, so they do not need to be magnetized in circuit and can be used with low permeance coefficients (i.e. thin discs).

These materials also lend themselves to Helmholtz coil testing due to their straight line normal curves. This also makes rare earths ideal for SMC and high field dipoles. Sm-Co has a good resistance to thermal demagnetization but is brittle.

NdFeB is less brittle, has poor thermal properties, and is prone to corrosion.
