What is the thermal hardness of cemented carbide?
The reason why cemented carbide (cemented carbide) can be widely used in aerospace, aviation, navigation, consumer electronics, national defense, military industry, medical treatment, automobile and other fields is that it has excellent physical and chemical properties, namely, high specific gravity, high hardness, high strength, good thermal hardness, wear resistance, heat resistance, acid and alkali resistance.

There are two types of fixture, namely, fixture and inspection fixture
The fixture is divided into two types, namely, fixture and inspection fixture. The former is used for machining, welding, processing and assembly and other processes to facilitate processing and meet the needs of accuracy. The latter is used for inspection. Because some mechanical dimensions are not easy to measure and their shapes are complex, it is necessary to design special inspection blocks or inspection tools designed for a certain product for inspection, such as plug gauges and ring gauges, But some of them are irregular, so we must design a special inspection tool to measure its size

FPC is what we often call flexible board, which is also called flexible circuit board. It is made of polyimide or polyester film and other circular substrates. It is light and thin, has high density, high flexibility, and can be bent and folded. It has advantages that other types of circuit boards do not have. Compared with traditional interconnection technology, FPC flexible circuit board can withstand millions of times of bending, easy installation, good heat dissipation, and is favored by the market.
