Smooth Finish
Investment casting uses a ceramic mold that can produce a much smoother finish, typically averaging 125 RA surface finish as cast.
Faster Production
Investment castings cut down on labor time and produce quicker lead times because it greatly reduces the amount of machining required after casting.
Tight Tolerances
Investment castings hold tighter tolerances, which reduces the amount of machining required. The standard tolerance is +/-.005 per inch.
Affordable Tooling
Investment casting requires less expensive equipment and is inherently less dangerous, which allows for costs to remain low.
Vast Size Range
Investment casting allows for both large and small casts. Intricate, miniature parts that are 1/10 of an ounce or less can be cast, and also large parts up to 50 pounds can be cast.
Material Variety
There are a variety of materials that can be used for investment casting which range from bronze, stainless steel, and even aluminum.
Stainless Steel
Renowned for its corrosion resistance and excellent mechanical properties, stainless steel is frequently employed in food processing, medical, and marine applications.
Low Alloy Steel
This material offers improved mechanical properties compared to carbon steel. It's often used in applications that require high strength and toughness. Low alloy steel for investment casting enables robust parts for demanding environments.
Cast Aluminum
Lightweight and corrosion-resistant, cast aluminum is used in various industries, including automotive and aerospace.
Carbon Steel
Carbon steel is a cost-effective material that offers a good balance of strength and flexibility in investment casting.
Super Alloy
Superalloys are used for their ability to withstand high temperatures and corrosive environments. They are commonly used in jet engines and industrial gas turbines.
Cast Iron
Known for its excellent castability and machinability, cast iron is often used in automotive and industrial applications.
Copper Alloy
Copper alloys, including brass and bronze, are known for their excellent conductivity and corrosion resistance.
Special Alloys
Special alloys are used for specific applications that require unique properties. These can include high strength at high temperatures, magnetic properties, or resistance to wear. Such Titanium alloys, Cobalt Alloys, and Nickel Alloys.
Tooled metal master die
Perfect tooling is required to produce a master die that can be used to create the expendable wax patterns which will then be invested to form solid ceramic moulds.
Creation of wax patterns
Wax patterns are created from the original 3D master die or tool. The patterns are assembled onto a ‘runner', chosen based on the feed requirements for that part.
The investment process
The wax assembly is then repeatedly dipped or ‘invested' in layers of liquid slurry alternated with dry ceramic stucco to build up a semi permeable layer that will dry to form a solid shell. Care must be taken to ensure that the slurry is at the precise temperature and viscosity to form the right thickness and quality of investment for the eventual casting of your specific component. The dipped and coated runner carrying the invested wax patterns is then air dried slowly over several days.
Wax removal by autoclave
The sacrificial wax is removed by heating the assembly in an autoclave, calculated to melt the wax without causing it to expand and break the mould. The ceramic shell is fired to sinter the mould, partially fusing the ceramic and removing the binder. This also pre-heats the mould ready for pouring.
The Pour
The hot ceramic mould can now be carefully filled with molten metal. The foundry team must ensure that the metal or alloy is at exactly the right temperature for the best pour (which will depend on the type of material being cast), and that the process of clamping, pouring, and rotating the moulds is handled correctly to deliver molten metal at the right temperature throughout the casting.
Finishing
After cooling for several hours, the ceramic shell can finally be mechanically removed to reveal the cast metal parts. Individual cast parts can then be finished as required, including shot blasting and heat treatment, machining and so on.
Inspection and testing
Throughout the process, monitoring takes place to check the quality of the casting and that the final cast part meets specifications. This includes non-destructive testing.

Our Service
● If you need custom products, first we need open the grinding tool according to your technical drawing, then we produce the sample for your check.
● If it's OK for you, then we start mass production, and every product will go through staff-check, Inspection visits, and final detection, that's to say 100% check not spot-check.
● All products has a one-year warranty period.
● And we offer 24x7 service during pre sales, mid sales, and post sales.
Packaging depends on the mold, parts and customer requirements.
Proper packaging and professional couriers will ensure fast and good delivery of goods.
