Dalian castings play an important role in modern industry, with a wide range of applications and continuously improved manufacturing processes. By continuously improving production technology and process level, the quality and performance of castings will be further improved, making greater contributions to the development of various industries.

The advantages of castings include easy production of complex shaped and large-sized components, high production efficiency, high material utilization, and low cost. In industrial manufacturing, the application range of castings is very wide, and products of various shapes, sizes, and materials can be produced to meet the needs of different industries.

What are the key technologies for manufacturing castings in Dalian

The selection of casting materials: The quality and performance of castings largely depend on the selection of casting materials, including metals, alloys, casting sand, etc. Different materials have different characteristics and applications, and it is necessary to choose suitable materials based on the specific requirements of the castings.

Mold design: A mold is the mold of a casting, which directly affects the shape and surface quality of the casting. The design of the mold should take into account factors such as the fluidity and shrinkage rate of the casting material to ensure the smooth progress of the casting process.

Pouring system design: The pouring system is a pipeline system that transports molten metal into the mold cavity, and its design should consider the fluidity and filling properties of the metal to avoid the generation of pores and impurities.

Melting process control: Melting is the process of heating metal to a liquid state, controlling parameters such as temperature, insulation time, and stirring method during the melting process, which can affect the microstructure and properties of castings.

Casting process control: The casting process includes pouring, solidification, cooling, and other links. By controlling parameters such as casting temperature, speed, and pressure, it is necessary to ensure the accuracy of the shape and size of the castings.

The manufacturing process of castings mainly includes mold design, melting, casting, and subsequent processing. Design corresponding molds based on the shape and size of the components, and the design of the molds directly affects the quality and shape of the final castings. Then, the metal materials (such as iron, aluminum, copper, etc.) are heated to a liquid state, and the control of casting temperature plays a crucial role in the quality of the castings. Next, pour the melted metal liquid into the mold and wait for it to cool and solidify before taking out the formed casting. Process, clean, and surface treat castings to ensure they meet product requirements.

Cast parts are a common type of engineering materials, referring to components or products made through casting processes. Casting parts are widely used in various fields such as automobiles, machinery, aerospace, etc., and are an indispensable and important component in industrial production.
