Strong Neodymium Magnets Process Steps

Neodymium magnet, also known as NdFeB magnet, is a tetragonal crystal formed by neodymium, iron, and boron (Nd2Fe14B). In 1982, Sumitomo Sasakawa found a neodymium magnet. The magnetic energy product (BHmax) of this magnet is larger than that of the SmCo magnet, which was the largest material in the world at that time. Later, Sumitomo special metals successfully developed the powder metallurgy process, and General Motors successfully developed the melt spinning process, which can prepare NdFeB magnets. This kind of magnet is a permanent magnet which is next to the absolute zero holmium magnet, and it is also the most commonly used rare earth magnet. NdFeB magnets are widely used in electronic products, such as hard disks, mobile phones, headphones, and battery-powered tools.

Neodymium iron boron magnet is divided into sintered neodymium iron boron and bonded neodymium iron boron. Bonded neodymium iron boron is magnetic and corrosion-resistant in all directions. However, sintered neodymium iron boron is easy to corrode and needs to be coated on its surface, generally including zinc plating, nickel, environmental zinc, environmental nickel, nickel copper-nickel, environmental nickel, etc. The sintered NdFeB is generally divided into axial magnetization and radial magnetization, which are determined according to the required working face.

Process Step of Neodymium magnet

1. Raw material preparation and pretreatment
Process Description: the raw materials are pre-treated by weighing, crushing, breaking and derusting.
Process equipment: steel cutting machine, drum polishing machine, etc.

2. smelting
Process Description: the raw materials such as praseodymium neodymium, pure iron, and ferroboron after pretreatment are proportioned, added into the vacuum smelting furnace, and the belt is thrown after high-temperature smelting under the protection of argon. The results show that the product has uniform composition, high crystal orientation, good microstructure consistency and avoids the formation of λ – Fe.
Process equipment: vacuum melting furnace

3. hydrogen burst
Process Description: The hydrogen explosion (HD) process is to use the hydrogen absorption characteristics of rare-earth intermetallics to place the neodymium iron boron alloy in the hydrogen environment. Hydrogen enters the alloy along with the neodymium rich phase thin layer so that it expands, bursts and breaks, and cracks along with the neodymium rich phase layer, ensuring the integrity of the main phase grains and the neodymium rich intergranular phase. HD technology makes the Nd-Fe-B casting very loose, which greatly improves the efficiency of airflow mill and reduces the production cost.
Process equipment: Vacuum hydrogen treatment furnace

4. flour milling
Process Description: airflow grinding is to use the high-speed collision of the material itself to pulverize, without abrasion and pollution to the inner wall of the grinding chamber, so the powder can be prepared efficiently.
Process equipment: air mill

5. Forming orientation
Process Description: the function of orientation is to turn the easy magnetization direction c axis of disorderly oriented powder particles in the same direction, so as to obtain the maximum remanence. The main purpose of pressing is to crush the powder into a certain shape and size while maintaining the grain orientation obtained in the magnetic field orientation as much as possible. We design and use the forming magnetic field press and isostatic press for the secondary forming. For the special-shaped magnet, we use special mold tooling to directly form. After sintering, the magnet can be put into use only with a little surface treatment, which greatly saves the cost of materials and subsequent processing.
Process equipment: magnetic field press, isostatic press

6. sintering
Process Description: sintering is a simple and cheap way to change the microstructure of materials and improve the magnetic properties of materials. Sintering is the final forming process of materials, which has a very important influence on the density and microstructure of magnets.
Process equipment: vacuum sintering furnace

7. Machining
Process Description: the Nd-Fe-B magnets obtained after sintering are all blanks, which need further machining to obtain products of different sizes, sizes, and shapes. Because of its brittleness and poor mechanical properties, NdFeB magnets can only be ground and machined.
Process equipment: surface grinder, double face grinder, chamfering machine

8. Surface treatment
Process Description: surface treatment of various shapes of rare earth permanent magnets, such as electrophoresis, zinc plating, nickel, nickel copper-nickel, and phosphating, to ensure the appearance and corrosion resistance of products.

9. Inspection and packaging of finished products
Process Description: to test all kinds of magnetic properties, corrosion resistance, high-temperature performance, etc. of the products, and pack them after reaching the standard, so as to meet the needs of customers.

How are the Low-Code Application Platforms Classified into Different Types?

Low-code is no longer a new thing for all of us. Everyone from a company’s project manager to an IT professional can now create web and mobile applications with little or no coding, just because of low-code application platforms. But be careful; not all low code application platforms provide the same services. So, if you’re a newbie in the low-code market, make sure that you’re well aware of different types of low-code application platforms before you spend on the vendor of your choice. You should select the one, according to your demands.

Classification of Low-Code Application Platformsfor

Low-code application platforms are classified into two categories. Both these categories are further divided into different types. Now let’s discuss all, one by one!

#1. Low-Code Platforms Categorized by Different Users

Low code application platforms give a considerable benefit to either business users or developers. But if you’re looking for a platform that can do both, then it’s rare. If the low-code application platforms pay attention to enhancing the acceleration of developers, it is often too complicated for the general public. On the other hand, the professional developer will be irritated and frustrated at the absence of customization if the low-code application platforms attempt to make coding simple enough for anyone to understand and use it.

1.      Low-Code Application Platforms for Business Users

Such low-code application platforms that are specially designed for business users have little coding. In this way, anyone can become a citizen developer and can build apps using easy-to-use platforms. No doubt, it is easy to become a citizen developer, but still, it may require the assistance of actual developers to make what they want.

2.      Low-Code Platforms for Professional Developers

Such low-code application platforms are developed for professional developers to build apps of any complexness. These also help them to save the time that they wasted on conventional hand-coding. So, these platforms help them out to increase the speed of their work with accuracy.

# 2: Low-Code Platforms Categorized by Use Case

According to the intentional goal or usage, there are different types of low-code application platforms.

Given next are the five major types of the platform:

1.      Process

These types of platforms mainly concentrate on applications that drive business-related processes.

Favorable for;

  • Going paperless
  • Approval workflows

2.      General Purpose

These low-code application platforms generally involve developing the app’s back-end or front-end and can create any app virtually.

3.      Request-Handling

These platforms are identical to process-based low-codes and are not that much efficient. They can only deal with processing requests for fixed operations.

4.      Mobile Application Development Platform (MADP)

These platforms are ideal for testing, coding, and launching mobile applications for tablets and smartphones by developers.

5.      Database

These platforms only grant access to grab data from databases programmed inside the system\network and are restricted.

Verdict

So, different types of low-code application platforms serve varied users and requirements, and you should be aware of the specialties of each before making the right purchase for you. If you’re searching for a definite beginning to your exploration for a perfect low-code application platform for business users, then you should go for WaveMaker.

Employee Tracking Software

Everyone has encountered a phenomenon where workers and apprentices tend to relax and unwind a little more when you are not in the room or the building. Do you want to be able to monitor your employees better? This is where an employee tracking software can be particularly useful.

Employee Tracking System allows you to track the activities of your employees through their company mobile phones. This means that you can track their names in address books, text logs, call history, GPS location, etc. It lets you know exactly what your employees are doing during the time of payment and at what time. All this happened. This method is completely legal and safe, and it is a great way to ensure your employees are as productive as possible.

First, you need to study your program as closely as possible. Since this is often done without your employees knowing, you need something accurate, fast, and undetectable. You’ll also need something compatible with various phones. Finally, since this spyware is available at different prices, you will need one that fits your budget.

Tracking employees using cell phone monitoring is one option for employers, but it has several obvious benefits.

  • Mobile Phone Abuse – Do your employees spend all day talking or texting? With accurate call and SMS logging, you can find out exactly how long he has been on the phone.
  • Employee tracking improves employee efficiency by providing accurate location data, giving you support where and when you need it.
  • Industrial espionage Whether you suspect one of your employees is colluding with competitors, mobile phone spying technology can notify you when a certain number is called, allowing you to eavesdrop.
  • Sick day abuse – By tracking employees, you can see if they’re at the doctor’s, at home, in bed or the game.

Employee Tracking Software Protects Confidential Information

This type of program is also designed to protect both employees and the company itself. Almost every industry uses confidential information about customers, customers and employees, and potential proprietary information or trade secrets. Securing this information is a key component of business continuity.

Not all threats to the security of confidential information constitute a direct attack on the network or sabotage in the office. There are other, more accurate ways to access restricted information. There have been many cases of people trying to portray themselves as customers, suppliers, or even administrators in a company to trick employees into giving up sensitive data or information. In addition to a keystroke recorder, employee tracking software can act as a preventive measure against this type of activity and provide an additional layer of protection for employees against such threats.

As a business owner, suppose you are going to cover the significant costs of providing all of your employees with a company phone. In that case, it makes sense to use the employee tracking software for maximum benefit to the company, and knowing where the help desk or delivery staff are during the day improves planning & support dramatically.
