The valve, is an important adjustment device in the fluid transportation system, which can basically control the on-off, flow and flow direction of the fluid. There are many types and specifications of valves, and the valves used for different work requirements are also different. The working principles, advantages and disadvantages of five common types of valves are described is this article.
A light sensor is a sensor that converts light signals into electrical signals using photosensitive elements. The light sensor is usually composed of a set of light projector and light receiver. Light sensors are generally composed of three parts: light source, optical path and optoelectronic components. The measured changes are converted into changes in optical signals are further converted into electrical signals with the help of photoelectric elements. In the future, with the development and popularization of Internet of Things technology, the application of light sensors will penetrate into all aspects of human life.
In the semiconductor industry, wafer has always been mentioned. But what exactly is a so-called wafer? What does the 8 inches, 12 inches refer to? How difficult is it to produce large-sized wafers? The following is a step-by-step introduction to the most important foundation of semiconductors, wafer.
The new generation of HMI will replace traditional buttons, indicators and selectors with updated technology and components, reduce the dependence on a large number of display panels and cables, and reduce operating costs through advanced HMI functions to enhance monitoring of equipment.
When it comes to maintenance tools, many people strongly recommend electric tools, which have many varieties, easy to use, and low prices, especially suitable for home use. But you know what? There is also a powerful and efficient tool in the tool industry, that is, pneumatic tools. So, what is the difference between the two, and how should one choose? Let this article tell you now.
Gears are mechanical parts with teeth that can mesh with each other to transmit motion and power in mechanical transmission. Gear transmissions stand out due to the accuracy of their gear ratio, which makes them perfect for precision machinery.
Under the influence of the epidemic, the global demand for telemedicine has increased significantly. The development of digital medical care is an important means to promote medical equality and achieve comprehensive health coverage. Telemedicine care will become the new medical routine "New Normal", and the integration of AI wisdom in medical technology will be accelerated after the epidemic. An important trend with information flow.
A charging station is a device that supplies electric energy for electric vehicles (including pure electric vehicles and plug-in hybrid electric vehicles), similar to the gas station used in fuel vehicles. How does it work and in what scenarios? Let’s find out.
Injection molding machine, also known as injection machine, is a special machine for manufacturing plastic products. There are many types of injection molding machines, which can usually be distinguished by the following methods: driving mode, mold opening and closing direction, applicable raw materials, mold clamping structure, and injection structure.
With the global electric vehicle market, the speed of research and development of new electric vehicles has been accelerated, and the density of charging stations has been continuously increased. Under the booming development, when consumers buy electric vehicles, they hope to enjoy the convenience of battery as the existing internal combustion engine vehicles that enjoy the relatively high density of gas stations, and the short single refueling time. Don't want to spend too much unnecessary effort of "power charging".
Hardware can be seen everywhere and used everywhere in our lives, especially on some large and small machines, many parts of which are made of hardware. It can be used separately or as an auxiliary, such as hardware tools, hardware parts, daily hardware, construction hardware and security supplies, etc. Let's learn what hardware includes and the classification of hardware accessories.

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.
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.
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.
Humans and robots working together can greatly reduce enterprise costs and improve team work efficiency. Such a “Human-Robot-Collaboration, HRC” model is bound to become the mainstream in the future, bringing industrial innovation and a more convenient life.
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.
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.
In recent years, the term functional fabric has emerged in major clothing brands and the textile industry, which refers to textiles or clothing products made of new types of textile materials with various functional demands. Clothing is a necessity of human life, and it also acts as an intermediary role between the human and the environment. It helps and adjusts to make people's lives more comfortable and safer, and the value of clothing is further improved.
The new epidemic has already changed people's living habits. Among them, home fitness has set off a wave, and some consumers have purchased related equipment for this purpose. Even if the epidemic is over, they may not return to the gym again. Under this trend, how can companies such as Lululemon and Nike use technology and big data to create a better "home fitness" experience? The epidemic has sparked a wave of home fitness, driving the sales of all kinds of home fitness equipment soaring, such as kettlebells, dumbbells, etc. all sold out of stock. Many start-ups and sports brands have also sensed business opportunities, launched various home fitness equipment, and used high-tech, big data and other technologies to create user-friendly "home gyms".
