Welcome to CFS' Blog
We share information, tips and things we’ve learned from our years in the metal casting and CNC machining industry.
What is Investment Casting?
Investment Casting Overview Investment casting is a lost wax precison casting technique with decades of history. It is mainly suitable for producing complex metal parts in various shapes with mass production. Investment casting begins by developing a wax model which accurately represents what will eventually become part of the final product. This wax model is then enclosed in a durable ceramic. After the outer shell is solidified, the inner wax layer is melted off and removed to create an empty ceramic mould. This cavity is then filled with molten steel, which assumes the exact shape and size of the
Aluminum Die Casting for Lighting Industry
Aluminum die casting is a popular manufacturing method for the lighting industry due to its versatility and cost-effectiveness. This process involves injecting molten aluminum into a mold to create complex shapes with high precision
Low Pressure Die Casting
Low Pressure Die Casting (LPDC) is a casting process that injects molten metal into a reusable mold under low pressure. This casting technique offers high quality, precision, and efficiency, making it highly favored for
Lost Wax Casting
Lost wax casting has a long history dating back more than five millennia, and today is one of the primary casting techniques worldwide. Currently, it has developed to produce numerous complex metal components used
Gravity Die Casting
At CFS Foundry, our gravity die casting technique can make quality cast parts for a range of industries, including Marine, Cars & Trucks, Gas Turbines, Compressors, Pumps, Valves, Medical Equipment, etc. What is Gravity

Besides aluminum forging or aluminum machining, lots of aluminum parts are created by casting process. In China, the main aluminum casting methods are: gravity die casting, pressure die casting and sand casting. The selection of a suitable aluminum casting method depend on several factors, such as part structure, aluminum grade, cost, quality, etc. CFS Foundry […]
Besides investment casting, gravity die casting is also one of the casting methods that available in CFS Foundry. Our gravity die casting process is mainly used to produce aluminum components for industrial applications. Gravity die casting has a limitation on the metals poured, not all the metals could be made by this type of casting […]
Besides martensitic and austenitic stainless steels, duplex stainless steel is also the metal type used in investment casting process. Duplex stainless steel has a ferritic-austenitic microstructure, with a phase balance of approximately 50% ferrite and 50% austenite. Combining the advantages of ferritic and austenitic stainless steels, investment casting of duplex stainless steel can creat components […]
A bottle opener is a common device in our daily life that can quickly remove metal bottle caps from glass bottles. To resist rust, stainless steel is used as the material. Investment casting can produce stainless steel bottle openers in different types, including crown cork bottle opener, wall-mounted bottle opener, etc. Investment casting is a […]
The aluminum is one of the popular casting metals for industrial applications. Casting of aluminum alloys involves a puring process into the mold to form solid aluminum components. The common aluminum casting methods are die casting, sand casting, and gravity die casting. There are a wide selection of aluminum casting suppliers in the world, even […]
Somtimes, a stainless steel part could be produced in different ways, such as investment casting, welding, etc. CFS Foundry worked with a customer on a stainless steel investment cast mounting bracket, which was made by welding. Stainless steel investment casting of mounting Bracket can significantly reduce weight, simplify logistics, improve quality, cut costs, and support […]
The exhaust transition body is connected to a valve that controls the pressure to the turbocharger in the aircraft engine. The stainless steel exhaust transition body was previously machined from a solid block of stainless steel because volumes were low and the end-user assumed this process would save on delivery time and tooling costs. This […]
Exhaust mixing elbows are the critical component used in marine engines where the excess cooling water is injected and mixed with the exhaust gases exiting the engines exhaust manifold, this cools the exhaust and also attenuates noise levels. For its working environment in seawater, stainless steel is usually selected as the material of exhaust mixing […]
Boat Deck Drain is also one of the common boat plumbing fittings for marine application. Like other cast stainless steel boat hardwares, the boat deck drain is also investment cast in 316 stainless steel. Marine grade 316 stainless steel can help boat deck drains to achieve maximum corrosion resistance and durability in the saltwater environment. […]
CFS’ gravity die casting foundry is located at the Ningbo, China. This casting type is ideal to produce small to medium-run components in Aluminium or other non-ferrous alloys. Aluminium Gravity Die Casting is a permanent mould casting process that produces aluminum parts in good surface finish, intricate shape and little subsequent or no machining is […]
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 […]
The top cap is the marine boat fitting designed for sailboat and powerboat bimini tops. Together with top slide or deck hinge, it can accept tubes in different diameters. Like all the cast marine boat fittings, the top cap is also made in 316 cast stainless steel. Stainless Steel Investment Casting Process When it comes […]
