A pair of molds is composed of an upper mold and a lower mold. The male die is a concave die, also known as the upper die. The design of the male mold is very important, and the structural characteristics of the female mold itself change with the structure of the product and the processing method of the mold, which is flexible.
Rapid molding technology is a fast, convenient, and practical mold manufacturing technology. It is especially suitable for the development and trial production of new products, process verification, and functional verification, as well as multi-variety and small batch production.
The commonly used control items on industrial pipelines and equipment mainly refer to some commonly used valves, which are used to control the flow of the medium in the pipeline.
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 5 common types of valves are described below.
Taiwan's hand tool industry is well-known in the world and once created the title of the screw kingdom. At present, the hand tool industry is faced with the challenges of the international situation, lack of manpower, exchange rate and other factors, coupled with the rise of emerging countries and the same industry in mainland China, what should they do to deal with the chaotic situation?
Although the figure of the fastener is inconspicuous, it is a rare but important existence in daily life. Fasteners are used in aircraft carriers, airplanes, high-rise buildings, as small as watches, mobile phones, glasses, etc.
A wrench is a tool used to turn bolts, nuts, and other objects that are difficult to turn by hand. A wrench is a tool that uses the principle of leverage as its actuation mechanism.
CBN turning tools are tightly sintered from boron nitride and tungsten carbide bases. The hardness of boron nitride is next to PCD. It has excellent chemical stability and will not produce affinity with iron, cobalt, and nickel-based metals. Therefore, it is especially suitable for work hardening steel, with a hardness above HRC45. Chilled cast iron and heat-resistant steel (Inconel) are also suitable.
Turbine blades are an important component of the turbine section in a gas turbine engine. The high-speed rotating blades are responsible for drawing high-temperature and high-pressure air into the burner to maintain the engine's work.
A micrometer is a measuring tool used to precisely measure lengths on small scales. In principle, spiral micrometers can be divided into mechanical micrometers and electronic micrometers. The mechanical micrometer is made according to the principle of spiral magnification.
Collet is a cylindrical fixture used to install a drill bit or a milling cutter on a milling machine. It is a fixing device used to fix and reinforce parts that need to be modified.
Bearings are crucial parts in mechanical equipment. Its main function is to support the mechanical rotating body to reduce the friction coefficient of the mechanical load during the transmission process of the equipment. This article will share the characteristics, differences and corresponding uses of several common bearings.
Ball screws are high-efficiency feed screws that contain balls that rotate between the screw and nut. Compared with the traditional slide screw, the driving torque is less than one-third, which is most suitable for saving the power of the driving motor.
Bearings are components that fix and reduce the friction coefficient of loads during mechanical transmission. It can also be said that when other parts move relative to each other on the shaft, it is used to reduce the friction coefficient in the process of power transmission and keep the center of the shaft fixed. Bearings are an important part of modern mechanical equipment. Its main function is to support the mechanical rotating body to reduce the friction coefficient of the mechanical load during the transmission process of the equipment. This article will continue to share the characteristics, differences and corresponding uses of several common bearings.
The global industrial valve market will reach 85.6 billion U.S. dollars in 2022. From the perspective of product technology leadership, European countries, especially Germany, and the United States, are the main leaders, followed by Taiwan, Japan, South Korea, China and India.
With the continuous development of the downstream industry of linear actuator and the continuous expansion of linear actuator applications, the global demand for linear actuator has shown a rapid growth. In 2019, the global linear actuator market has exceeded 15 billion yuan.
