To cast a metal means to shape it by melting it then pouring it into a mold. As the metal cools and solidifies, it adopts the shape of the mold that surrounds it, and once it is completely cool it can be withdrawn. When they want to make cast aluminum products, manufacturers can choose between several methods. One of these is called die casting. In die casting, the manufacturer melts the aluminum ...

Traditional faucets are made of brass. The process flow is as follows: copper ingot→dissolving→casting→cleaning after casting→casting inspection→machining→tolerance inspection→grinding→surface inspection→plating→plating inspection→assembly→pressure test→ Finished product inspection → packaging → delivery. There are a total of 16 processes, and each process is strictly controlled to ensure quality....

Butterfly valve is a frequently used valve in industrial water system. It has become a common valve for pipelines because of its small size and high cost performance. The main products of butterfly valves are wafer soft-sealed butterfly valves and flanged butterfly valves. Although there are fewer types of butterfly valves than gate valves, there are also many differences to adapt to different wor...

Gravity casting refers to the process of injecting molten metal into a mold under the action of the earth's gravity, also known as casting. The generalized gravity casting includes sand casting, metal casting, investment casting, lost foam casting, mud casting, etc.; the narrow gravity casting specifically refers to metal casting. The molten metal is generally poured into the gate manually, and th...

At present, more than 80% of copper in the world is made by fire method, and it is mainly used to process copper sulfide ore. Pyrometallurgy is to melt copper ore (or calcine, agglomerate, etc.) and flux at high temperature, or directly smelt into blister copper, or first smelt into matte (melt mainly composed of copper, iron and sulfur) Then smelt into blister copper. Except for some operations (...

Brass is a copper alloy with zinc as the main alloying element. According to its chemical composition, brass is divided into two types: ordinary copper and special brass. (1)Ordinary brass is a binary alloy of copper and zinc. Due to its good plasticity, it is suitable for manufacturing plates, bars, wires, pipes and deep-drawn parts, such as condenser tubes, radiator tubes, and mechanical and ele...

The valve body is one of the main parts of the valve; there are different mechanical manufacturing methods according to the pressure level. For example: casting, forging, etc. The definition of "valve" is a device used to control the direction, pressure, and flow of fluid in a fluid system. A valve is a device that allows the medium (liquid, gas, powder) in the piping and equipment to flow or stop...
