Factors affecting the dimensional accuracy of precision castings

In general, the dimensional accuracy of precision castings is influenced by various factors such as casting structure, casting material, mold making, shell making, roasting, pouring, etc. Any unreasonable setting or operation of any link can cause changes in the shrinkage rate of the castings,

The Importance of China's Foundry Industry

The casting industry in China has always been an important, fundamental, and irreplaceable industry in the national economy, with the advantages of relatively low cost and wide process adaptability. China is a major foundry country,

Emission reduction and energy conservation in casting enterprises are urgent

Recently, the National High tech Energy Conservation and Emission Reduction Promotion Center issued an initiative to enterprises across the country: taking sustainable development as the business management concept, using high-tech as a means, continuously reducing energy consumption costs in production through technological and process innovation,

What are the General technology requirements for castings?

According to usage requirements, acceptance requirements shall be specified for other defects in castings. Such as pores, sand holes, shrinkage holes, shrinkage porosity, slag inclusion, sand inclusion, cracks

What is precision casting? How do we apply it?

The term precision casting may be unfamiliar to us, as it is not easy for us to see such a process. We believe that its finished products are not very unfamiliar, as such products are available in every corner and are utilized in various fields of application.

How to solve the problem of shrinkage and porosity in die castings and other castings

The problem of shrinkage and porosity in die castings and other castings is a common phenomenon. Is there a complete solution to this problem? The answer should be yes, but what would it be?

What should be paid attention to when designing the structure of castings?

Due to the fact that castings cool and solidify faster in the metal mold than in the sand mold, and the metal mold has no tolerance, the casting stress generated in the metal mold casting is greater than that in the sand mold casting, and the tendency to crack is greater.

Advantages and disadvantages of casting parts

Casting refers to the process of pouring a substance that is liquid at room temperature but soon solidified into a specific shaped mold for solidification. The cast material is mostly a metal that is originally solid but heated to a liquid state (such as copper, iron, aluminum, tin, lead, etc.),
