Metal heat treatment is a process in which the metal product is heated to an appropriate temperature in a certain medium and cooled in different medium at different speeds after being kept at this temperature for a certain period of time, and its properties are controlled by changing the surface or internal microstructure of the metal material. Heat treatment improves hardness, strength and wear resistance. Reduce hardness and improve cutting performance. Eliminate internal stress generated during casting, forging, welding, etc. Improve surface wear and corrosion resistance.
With the development of automobile, machinery, aerospace, instrumentation and other industries,the application of aluminum die castings are gradually expanded.Meanwhile,aluminum die casting purchasers also put forward higher requirement on the surface quality.Now we would like to introduce shot blasting for aluminum die castings.
Tongda is a technical investment casting foundry producing various precision investment castings.By professional investment casting production equipment,strong techincs,strict quality control system and impeccable testing equipments,we have win great trust and support from investment casting users.Investment casting is a casting method that is made of fusible material,casting refractory to form sheel melt model and get castings after injecting liquid metal material.Now we would like to introduce how Tongda do surface cleaning for investment castings
Carburizing treatment is one kind of heat treating processes for investment castings. Carburizing treatment can increase the content of carbon elements in certain layer of the castings. Thus, to increase the strength of the castings.
Mould is one of the important technology and equipment, industrial products production in the modern industrial production, 60% - 90% of the industrial products need to use the mold, the mold industry has become the foundation of industrial development, development and the development of many new products largely depends on the mold production, especially in automobile, motorcycle, light industry, electronic, aviation, etc.
High pressure die casting and lost foam casting are both casting methods which widely used in automobile industry,telecommunication industry,medical industry etc.Both of casting methods can produce parts with complex geometry shape at tight tolerance requirement.But they are typically used for some parts respectively.
