Preparation of Ultrafine Metal Powder by Ball Milling
Abstract: Superfine metal powder has the characteristics of small size and large specific surface area. The metal parts made from it have excellent mechanical properties, special magnetic properties, high conductivity and diffusivity, high reaction activity and catalytic activity. Therefore, ultrafine metal powder materials can be widely used in aerospace, ship, automobile, metallurgy, chemical industry and other fields.
Process Flow of Metal Powder Injection Molding
Abstract: Metal injection molding (MIM) is a kind of molding method in which the plasticized mixture of metal powder and its binder is injected into the mold. MIM process is divided into four processing steps (mixing, molding, degreasing and sintering) to realize the production of parts, and the surface treatment is determined according to the product characteristics. The specific process flow is as follows:
Metal Powder Injection Molding (PIM) is Suitable for Which Type of Industries?
Abstract: The application of metal powder injection molding in the industry can be divided into two categories: civil and military. Civil category mainly refers to 3C, medical treatment, tools, automobile, communication, lighting, wearing, locks, catering, etc. Military industry refers to aerospace and machinery. The details are as follows:
How to Test the Fluidity of Metal Powder?
Abstract: Fluidity is an important performance index of metal powder for 3D printing. SLM, EBM, LENS and other processes have high requirements on the fluidity of metal powder. So, as a buyer, how to test the fluidity of metal powder to judge whether it meets the requirements? Today, the author would like to share with you the most commonly used test method of powder fluidity hall flow rate method.
Titanium Powder Preparation by Reduction Method
Abstract: At present, the preparation methods of titanium and titanium alloy powder can be divided into the following two types: 1) titanium compound reduction method; 2) titanium raw material crushing or atomization method. In addition, titanium powder needs to be modified to meet the special technological requirements.
What is the Cause of Coating Shrinkage? How to Solve It?
Abstract: Various problems may occur during electrostatic powder spraying. The coating shrinkage is one of them. So, when we encounter the coating shrinkage cavity, how should we deal with it?
How to Deal with Impurities in the Coating During Electrostatic Powder Spraying?
Abstract: Powder electrostatic spraying refers to the electrostatic generator releases high-voltage static electricity (negative electrode) to the space in the direction of the workpiece through the electrode needle at the gun mouth. The high-voltage static electricity ionizes the mixture of powder and compressed air ejected from the gun mouth and the air around the electrode (with negative charge). The powder is driven by electric field and compressed air pressure to the surface of the workpiece, and a uniform coating is formed on the surface of the workpiece by electrostatic attraction. AEM Deposition can provide all kinds of metal powder. The details are as follows:

Classification and Introduction of Powder Coatings
Abstract: In recent years, the development speed of powder coating is quite amazing, and it still keeps about 10% growth under the pressure of the depression of the chemical industry environment. This is closely related to the characteristics and advantages of powder coating. Under the driving force of environmental protection requirements and technological innovation, it also provides enough power for the rapid development of powder coating. So, how is powder coating classified?
Principle and Application of Arc Additive Manufacturing
Abstract: When it comes to additive manufacturing, we usually think of laser additive manufacturing technology (3D printing) firstly. In fact, there are other types of metal additive manufacturing technology, which can be divided into four categories according to the type of heat source: laser, electron beam, plasma beam and arc; and two categories according to the type of raw materials: metal powder and metal wire.
