  • Heating and cooling method during heat treatment in precision casting

    2019-12-09 14:23:39
    Cooling is also an indispensable step during heat treatment process, cooling method is difference according to varies casting technology and heat treatment process,the most important is to control the cooling speed,generally annealing of cooling speed is the slowest, normalizing of cooling is faster and the quench of cooling is the faster than the others. Due to the above different steels have different requirements, such as empty hard steel can be hard by normalizing cooling speed.
  • Advantages & disadvantages of casting process

    2019-12-03 09:46:02
    Advantages and disadvantages of casting process Casting is a manufacturing process in which a liquid material is usually poured into a mold, which contains a hollow cavity of the desired shape, and then allowed to solidify. The solidified part is also known as a casting, which is ejected or broken out of the mold to complete the process.
  • Why we need improve the steel castings’ density?

    2019-11-26 11:48:35
    When manufacturing the custom steel casting components, we will carry out the heat treatment process to improve the quality and performance of steel castings.

    2019-09-12 16:23:37
    When casting or forging metal parts, several factors will influence the final properties of the material. These processes have an effect on the material’s internal condition of the material, e.g., the shape and dimension of the grain structure, the distribution of the alloying elements and the presence of unwanted chemical reactions.

  • Raw Castings vs. Machined

    2019-08-16 16:24:30
    For those familiar with Sand Castings, this is probably nothing new to you; but if you are new to the sand casting world this may clarify some things for you.

  • Investment Casting vs. Die Casting: 7 Considerations When Choosing a Process

    2019-07-11 16:11:33
    Casting -- one of the oldest known manufacturing techniques -- is a process in which liquid material (e.g. molten metal) is poured into a mold cavity and hardened.
  • Cleanliness requirements for alloy materials for superalloy castings

    2019-06-05 10:30:06
    In the production process of high-temperature alloys and their casting, the purity of high-temperature alloy castings is one of the most important technical problems.
  • Heat treatment vacuum heating has quenching and carbonization?

    2019-06-05 10:26:49
    There is a large amount of quenching oil in the workpiece entering and leaving the furnace, the material basket is polluted, the feeding trolley enters and exits into the hot chamber, and remains on the cold wall of the hot chamber. When heated, a volatile reducing atmosphere is formed to increase the carbon of the workpiece.
  • Why 1Cr18Ni9Ti will be replaced by 304 stainless steel tube

    2019-06-05 10:21:32
    The main reason for the use of 1Cr18Ni9Ti is that the content of C in 304 is relatively low, so its hardness is relatively low. The price of 1Cr18Ni9Ti is more expensive than 304, and the processing cost is relatively high. Therefore, it is generally mainly made of 304 material.
  • Heat-resistant steel castings, four fires in heat treatment

    2019-06-05 10:07:07
    When it comes to heat-resistant steel castings, we have to mention the heat treatment industry; when it comes to heat treatment, we have to mention four fires in the industry, annealing, normalizing, quenching and tempering. Today, let's talk about the difference between them. First, annealing
  • De-rusting method of cast aluminum parts and alkali etching treatment of cast aluminum parts

    2019-06-05 10:01:30
    It can be solved by changing the alkali etching procedure, that is, alkali etching treatment is performed after casting molding. According to the operation of the process, the occurrence of problems such as scrapping of the workpiece due to alkali corrosion can be prevented, and the surface quality after oxidation is favorable.
  • What are the hot forging of cast copper parts according to the application?

    2019-06-05 09:57:07
    Most cast copper parts are not heat treated and strengthened, but are used in the as-cast condition.
  • Metal casting

    2019-06-05 09:49:37
    Metal casting is a process in which a metal is smelted into a liquid that meets certain requirements and poured into a mold, and cooled, solidified, and cleaned to obtain a casting having a predetermined shape, size, and performance. Casting blanks reduce the cost and reduce the time to some extent due to the near-forming, to achieve no machining or a small amount of processing. Casting is one of the basic processes of the modern machinery manufacturing industry.
  • Principles of casting method selection in precision casting

    2019-06-05 09:42:33
    Sand type precision casting. According to statistics, in China or internationally, 60-70% of all castings are produced by sand, and about 70% of them are produced with clay sand.
  • Development prospects of investment casting precision casting technology

    2019-06-05 09:00:43
    The products obtained by investment casting are precise and complex, close to the final shape of the part, and can be used directly without machining or processing. It is an advanced process of near-net shape formation and an excellent process technology in the foundry industry. The application is very extensive.
