Monitor

Display Application

With the rapid progress of modern technology, monitors, as a window for media communication, are widely used in various industries. It is very important to stably ensure the current display quality and the improvement of future display quality, which corresponds to the quality of raw materials for display production. , and the important link of tungsten and molybdenum target sputtering coating on the display, the purity, density of raw materials, and the compactness of the internal structure are the key factors. It can be guaranteed that the various characteristics of the sputtering target meet the high-level display requirements of modern production.

Sputtering technology is one of the main technologies for the preparation of thin film materials. It uses ions generated by ion sources to accelerate and aggregate in vacuum to form high-speed energy ion beams, bombard the solid surface, and exchange kinetic energy between ions and solid surface atoms. , so that the atoms on the surface of the solid leave the solid and deposit on the surface of the substrate. The bombarded solid is the raw material for depositing thin films by sputtering, which is called the sputtering target. Various types of sputtered thin film materials have been widely used in semiconductor integrated circuits, recording media, flat-panel displays and workpiece surface coatings.

Sputtering Target Application：

Sputtering targets are mainly used in the electronics and information industries, such as integrated circuits, information storage, liquid crystal displays, laser memories, electronic control devices, etc.; they can also be used in the field of glass coating; they can also be used in wear-resistant materials, high-temperature corrosion resistance , high-end decorative products and other industries.

As one of the three processes of vacuum coating, sputtering coating is widely used in modern industries such as photovoltaic and TFT-LCD. Sputtering targets have high requirements for purity. Generally, tungsten and molybdenum sputtering targets require a purity of more than 99.95%, and have good density and corrosion resistance.

Craftsmanship

Raw Material

Starting from raw materials, we select high-quality raw materials, which is very prominent in the stability and consistency of products. Identify different brands of raw materials and mark the batch number. And each batch of raw materials shall be sampled, inspected and archived. Ensure the traceability of each finished product and continuously improve the product quality.

Milling

The control of the milling process of Mengchang Metal products is very accurate, with several large mixers and vibration platforms to ensure that the materials in the pulverizing and mixing process can be fully stirred and evenly distributed, so as to ensure the internal organization consistency of the products.

Suppress

In the process of powder compacting, the powder is pressed by isostatic pressing equipment to make its internal structure uniform and dense. Mengchang has very perfect batch mold, and also has isostatic pressing equipment to meet the production of ultra-large batches of products.

Sinter

In powder metallurgy, after the metal powder is formed by isostatic pressing, it is heated at a temperature lower than the melting point of the main components to make the particles connect, so as to improve the performance of the products, which is called sintering. After the powder is formed, the dense body obtained by sintering is a kind of polycrystalline material. The sintering process directly affects the grain size, pore size and grain boundary shape and distribution in the microstructure, which is the core process of powder metallurgy.

Forging

The forging process can make the material obtain higher density, better mechanical properties, and play a role in strengthening the surface. Accurate control of the processing rate and forging temperature of tungsten and molybdenum materials is an important factor for the superior performance of Mengchang tungsten and molybdenum materials. A processing method of using a forging machine to apply pressure to a metal blank to plastically deform it to obtain a forging with certain mechanical properties, certain shape and size.

Rolling

The rolling process makes the metal material produce continuous plastic deformation under the pressure of the rotating roll, and obtain the required section shape and properties. With advanced tungsten and molybdenum cold and hot rolling technology and equipment, from tungsten and molybdenum metal blank to the production of tungsten and molybdenum foil, mengchang guarantees you more advanced production technology and superior metal properties.

Heat-Treat

After the forging and rolling process, the material is subjected to the heat treatment process to completely eliminate the internal structural stress of the material, give play to the material performance, and make the material easier for subsequent machining. Mengchang has dozens of vacuum furnaces and heat treatment hydrogen furnaces to meet the rapid delivery of mass production orders.

Machining

The material of Mengchanghas undergone complete heat treatment, and then processed into various customized sizes by machining equipment such as turning, milling, cutting, grinding, etc., and ensures that the internal organization of tungsten and molybdenum materials is tight, stress-free and hole-free, which can meet the needs of customers.

Quality Assurance

Quality inspection and control will be carried out from raw materialsand for each steps of the production , so as to continuously ensure the quality every product. At the same time, when finished products are delivered from the warehouse, the appearance, size and internal organization of materials are tested one by one. Therefore, the stability and consistency of products are especially prominent.
