Pouring molten metal into three-dimensional molds to make metal parts is the basis behind both sand and investment casting. But there are significant differences between these two methods. Sand-Casting Basics In sand casting, molten metal is poured into a sand-based two-piece mold. Molds are created out of sand usually mixed with clay as a bonding […]
The investment casting is a wax duplicate of the desired casting created to be invested into a “Ceramic Slurry”. The slurry-covered investment can be dipped into alternating coatings of sand and slurry until a suitable thickness of the shell is achieved that can hold the molten metal after the investment is burnt out. The “Burn-Out” […]
The investment casting process draws a lot of attention because of its high-value products, but the technologies involved in the process are quite impressive in their own ways. Now a pilot-scale melting system is offering some promise for increasing the volumes and range of alloys for those high-value products. The FastCast concept developed by ALD […]
Sand casting and investment casting are methods of creating metal parts by pouring molten metal into three-dimensional molds. Although methods are thousands of years old, both have been refined over the years to minimize the amount of metal used and reduce any extensive machining and finishing required. But significant differences exist between these two methods […]
You have probably heard of investment casting and sand casting, but what is the difference between them? According to Brad Done with Machine Design: “Sand casting and investment casting are methods of creating metal parts by pouring molten metal into three-dimensional molds. Although methods are thousands of years old, both have been refined over the […]
