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.

Learn what PP protective film is and its properties. Learn more about the difference between common CPP film, OPP film, BOPP film, and MOPP film? What are the differences in its characteristics?

The indexing plate is mainly used for milling machines, but also commonly used for drilling machines and surface grinders. It can be used for index drilling or milling, circumferential cutting, circumferential surface machining, straight line machining of planes and part of line segments.

Each production facility has its maximum theoretical capacity, which must be achieved without any disturbance and quality loss. Of course, it is impossible to achieve completely zero loss or error in actual production. OEE is an independent measurement tool used to express the ratio of actual production capacity relative to theoretical capacity, grouped by key elements of availability, performance, and quality index.
