Cast Iron & Steel Sand Casting FoundrySand casting uses green sand (moist sand) or dry sand to form the molding systems. The green sand casting is the oldest casting process used in history, while the dry sand casting could be divided into lost foam casting and vacuum casting. When making the mold,

Machined aluminum parts apply to several manufacturing industries and come from machining processes such as CNC machining (comprising CNC milling, grinding, and CNC turning). Though all three are good aluminum machining processes, CNC milling is the most common machining method because of the comple

Abstract: In view of the high pollution of traditional water glass investment casting, the process upgrading scheme was discussed, and the silica sol thin shell process was confirmed as the best scheme. The process was optimized and upgraded from the aspects of mold material, tree formation, shell m

Abstract: The current trend of investment casting development is to realize green casting as well as improving andstabilizing the quality of the casting, The problem that the traditional water glass (or composite) shell substitutedto silicon-soluble shell in the investment casting industry is the lo

Abstract： Near net shape investment casting is a special casting method of less-cuttings, it is widely used in the complex structural parts of aerospace and automobile industry with bulk-production. In this paper, the research status of refractory material, binder and additives on shell-strengthen p

Abstract: This article introduces the transformation and upgrading of investment casting technology for water glass, achieving rapid shell making and batch application of investment casting silica sol. This process has been optimized and upgraded from the selection of mold and shell materials, addit

Investment casting is a liquid metal forming process with little or no cutting. It is an excellent process technology in the casting industry and is widely used. It plays an irreplaceable role in the forming of high-precision and complex structure castings such as aircraft engine turbine blades, gas

Abstract: The cracking and peeling of the surface layer in investment casting are long-standing problems that have not been solved in the precision casting process. Both silica sol process and water glass process existIn this issue. The solution to this problem in actual production. It's nothing mor

With the continuous development of aircraft engine technology, there is an increasing demand for precision casting size accuracy and casting quality, as well as longer service life requirements.This project focuses on the precision casting process of the exhaust valve housing of a certain type of ga

As an advanced near net forming technology, investment casting is widely used in the precision forming of difficult to machine parts and thin-walled complex components in fields such as aerospace, advanced manufacturing, and medical equipment. It has many advantages such as fast forming of complex c
