Casting shape manufacturing and core box applicationTime of issue : 2019- 09-07
The mold used to obtain the appearance of the casting is called a pattern, and the mold used to obtain the inner cavity of the casting is called a core box. Sometimes the core made of a core box can also be used to obtain the appearance of the casting. According to the manufacturing method and the material used in the core box, it can be divided into three types: wood mold, metal mold and plastic mold.
Hardware molds drive the development of die steel consumption technologyTime of issue : 2019- 09-07
China's hardware mold steel has gradually undergone earth-shaking transformation, and has become the world's hardware mold production base. In most areas, China's hardware molds have already occupied a very large quota. However, in many high-end fields, especially automotive hardware molds, precision metal molds, and high-efficiency hardware molds, they still have to be imported from abroad. Only a few companies in China have squeezed into the ranks of precision metal mold manufacturing.
What are the mold carbide materials?Time of issue : 2019- 09-07
Cemented carbide is made by high-pressure sintering of WC (tungsten carbide), TiC (carbonized carbide) and Co (drilled) powders with high wear resistance and high heat resistance, followed by high-temperature sintering. As a knot, the hardness of the cemented carbide is HRC74-82, which has a very high red hard temperature. The hardness required for cutting can be maintained at a high temperature of 800-1000 ° C. The cutting speed of a steel cutting tool can reach 100-300 m / min. The cutter can be used for high-speed cutting. The disadvantage is that the toughness is higher. Poor, brittle, and impatient, hard alloys are generally made into blades of various shapes, welded or clamped on the body. As shown in Figure 1-4, the commonly used cemented carbide has tungsten drill. There are two big categories of tungsten and diamonds.
Non-ferrous metal production capacity was further disturbed. Tin futures price rose 10.36% in 4 days.Time of issue : 2019- 09-07
Recently, following the nickel, another non-ferrous metal, tin, has been affected by the expected price reduction.
Yesterday, the main contract price of Shanghai-Silver futures jumped in the intraday, closing price reached 142,890 yuan / ton, the day rose 3.23%. At the same time, the tin concept stocks tin industry shares ushered in a straight line yesterday afternoon, once rose to 9.07%, closing finally rose 4.77%. However, industry insiders expect that tin prices are expected to remain strong in the short term, but the upside may be limited.
