The structural design of precision castings should not only meet the requirements of the machine equipment itself and the requirements of mechanical processing technology, but also meet the requirements of the casting process. The structural design of castings should pay attention to the following p...

Porosity is one of the common defects in precision casting, which refers to the appearance of smooth hole defects in individual positions of precision castings. Pores are usually discovered after machining. Based on years of workshop production experience, Yanzi's precision casting technicians h...

The precision, surface finish, material density, metallographic structure, mechanical properties, and other aspects of castings produced by sand casting are often poor. Therefore, when these performance requirements of castings are higher, other casting methods should be used, such as investment cas...

Precision casting, also known as wax loss casting, produces products that are precise, complex, and close to the final shape of the part, and can be directly used without or with little processing. Therefore, investment casting is an advanced process of near net formation.In ancient China, the Princ...

At present, the most direct development issue facing humanity is sustainable development. The waste and pollutants emitted by population growth and social progress have seriously exceeded the capacity of the Earth to dissipate, especially for foundries. Foundries in China are a traditional basic ind...

The production scale and variety of castings in China's casting industry are already at the forefront of the world. A strong industrial foundation provides a large number of castings (blanks and parts) for many industries.Since the reform and opening up, China has started to import and export ca...
