Aluminum alloys have the advantages of good plasticity, corrosion resistance and lightweight, making them ideal for automotive manufacturing, aerospace, shipbuilding and other fields. Due to the increasing demands of aluminum castings, the aluminum casting industry is rapidly growing in China. At present, the main aluminum casting methods are: pressure die casting and gravity die casting. As the professional aluminum casting company in China, let’s talk about the main differences between pressure die casting and gravity die casting. Gravity Die Casting Gravity die…

Most people have seen stainless steel castings at some point in their lives. They have likely seen cast stainless steel parts used in a wide variety of products, from kitchenware to medical instruments, yet few realize why so many designers prefer stainless steel castings. One of the most valuable assets of stainless steel castings is its resistance to corrosion. Lower grades of stainless steel castings can withstand corrosion in water environments and basic atmospheric conditions. And higher grades of stainless steel castings…

What is Duplex Stainless Steel Casting? Duplex Stainless Steel Casting is the casting process using duplex stainless steel as the material. Duplex stainless steel is called “duplex” because they have a two-phase microstructure consisting of grains of ferritic and austenitic stainless steel. The picture shows the yellow austenitic phase as “islands” surrounded by the blue ferritic phase. When duplex stainless steel is melted it solidifies from the liquid phase to a completely ferritic structure. As the material cools to room temperature,…

Gravity die casting replys on gravity other than high pressure to pour aluminum or zinc alloys which makes more simple for cast products. Here are some of its advantages: Parts are taken from mold directly, excellent dimensional accuracy. Compared with sand casting, the surface finish of gravity die cast parts is better. Mechanical properties, especially tensile strength, are superior to those made in sand casting. The wall thickness of parts can be bigger than those made by pressure die casting. Sand…

After understanding gravity die casting technique, maybe you will ask if it is cost effective to make parts by gravity die casting process? The answer is that gravity die casting is cost-effective for medium- and high-production runs of products. The cost per unit increases when a low volume of parts is required due to the high initial capital cost of the die itself. A die is machined from solid steel and, due to the irregular and customized design of each one, it…
