Lietojumprogrammu

Fasteners are a type of mechanical parts that are used for fastening connections and are widely used. Fastener Silica Sol Investment Castings All kinds of fasteners can be seen on various machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, meters, and supplies. It is characterized by a wide range of varieties and specifications, different performances and uses, and the degree of standardization, serialization, and generalization is also extremely high. Therefore, some people also refer to a class of fasteners with existing national standards as standard fasteners, or simply as standard parts. Fasteners are the most widely used basic mechanical parts. With my country's accession to the WTO in 2001, it has entered the ranks of international trade powers. my country's fastener products are exported to countries all over the world in large quantities, and fastener products from all over the world are also pouring into the Chinese market. As one of the products with a large import and export volume in our country, fasteners are in line with international standards, which has important practical significance and significance for promoting Chinese fastener companies to go global and promoting fastener companies to fully participate in international cooperation and competition. strategic significance. Due to the specification, size, tolerance, weight, performance, surface condition, and marking method of each specific fastener product, as well as the specific requirements of items such as acceptance inspection, marking, and packaging.

Parasti izmantotie testēšana instrumenti

The most important link in the development and design of fasteners is quality control. There are several major checkpoints from incoming materials to finished product shipments, and these major checkpoints have different inspection methods. First of all, the feed is related to appearance, size, elements, performance, harmful substance detection, etc.; the process is more about appearance, size, knocking test, and forging streamline; heat treatment is more about appearance, hardness, torque, tension, metallography, etc.; surface treatment is more about some hydrogen embrittlement tests, coatings, salt spray, etc., including a harmful substance test for shipments. In terms of size and appearance inspection, the common ones are a quadratic element, contour measuring instrument, three-coordinate measuring instrument, image sorting machine (this is a full selection machine); in terms of mechanical and chemical testing, there are mainly hardness machines (Rocket and Vickers) ), tensile machine, metallographic microscope; for material testing, there is a spectrum analyzer, salt spray testing machine.
