The advanced processing device and the high-efficiency CNC tool can give full play to its effect and obtain good economic benefits. Because the tool is subjected to high pressure, high temperature, friction, shock and vibration when cutting. Material is an important factor affecting the cutting ability of a tool, and also has a considerable impact on processing efficiency, processing quality, processing cost and tool durability.

Nowadays, products have many functions and high complexity, so the requirements for the quality and precision of molds are becoming more and more stringent. Only through a complete evaluation and testing in the early mold development process can we produce mold products that customers are satisfied with.

Die casting, called pressure casting, is a metal casting process characterized by the use of a mold cavity to apply high pressure to molten aluminum or zinc alloys. Die casting molds are often developed from stronger alloys, a process somewhat similar to injection molding. Most die-casting workpieces are iron-free, such as zinc, copper, aluminum, magnesium, lead, tin, and lead-tin alloys. According to the different requirements of the type of die casting, a cold chamber die casting machine or a hot chamber die casting machine is configured for die casting processing.

A welding method that uses the flame generated by the mixed combustion of combustible gas and combustion-supporting gas as the heat source to melt the weldment and the welding material to achieve interatomic bonding.

Ultra-precision machining technology is an important way to improve the performance, quality, service life and reliability of electromechanical products, as well as saving materials and energy. For example: improving the machining accuracy of cylinders and pistons can improve the efficiency and horsepower of automobile engines and reduce fuel consumption; improving the machining accuracy of rolling elements and raceways of rolling bearings can increase the speed of bearings, reduce vibration and noise; improve flatness of processing of magnetic disks, thereby reducing the gap between it and the magnetic head, can greatly increase the storage capacity of the magnetic disk; improving the marking accuracy of the semiconductor device (reducing the line width, increasing the density) can improve the integration of the microelectronic chip, etc.

The characteristics of co-extrusion extrusion technology are that the substrate layer and the adhesive layer are completely fused and the extruded film itself is integrally formed, and there will be no glue residue after long-term lamination. It can be customized to achieve the purpose of cost reduction and process simplification.

For sale and transportation of various products, mainly to stabilize, cover and protect products. The shrink film must have high puncture resistance, good shrinkage, and certain shrinkage stress.

Surface treatment is a process for artificially forming a surface layer with different mechanical, physical and chemical properties on the surface of the substrate. The purpose of surface treatment is to have the corrosion resistance, wear resistance, decoration or other special functional requirements of the product. For metal castings, the more commonly used surface treatment methods are mechanical grinding, chemical treatment, surface heat treatment, and spraying the surface. The following will talk about details among all these different methods.

RFID and NFC are both short-range wireless communication technologies. Since the former uses a variety of frequency bands, and the latter is developed for use in the mobile market, the development and application fields of the two are also different. RFID mainly focuses on radio frequency identification, which can be applied to the identification of items. Now RFID has been widely used in all walks of life; NFC mainly focuses on near-field communication and is used with mobile devices to achieve the application of mobile payment. In this article, we will talk more about the technologies and applications of RFID and NFC.

PE film is also called stretch film, stretch film, and stretch film. PE film is mainly widely used in centralized winding packaging of various goods. It can reduce the damage and collapse of the goods during the transportation process. The goods can be waterproof, dustproof, and highly transparent when packed with PE stretch film, and the varieties of the packaged goods can be easily distinguished.
