Investment Casting, Lost Wax Casting China - OTTOMMO Casting

We provide various casting process and brings many unique benefits to our customers. We have built three casting plants in the past 15 years in order to offer you more casting solutions. We have committed to our customers cost efficiency, freedom of design, reproducibility, reduced machining and increased performance. As we started as an investment casting foundry, we know details of this metal-forming technique. Investment Steel Casting China casting is also known as lost wax casting. Basically, it refers to make a wax pattern formed with a ceramic. Then, melting the wax makes the ceramic empty. Eventually we get the casting after pouring the metal into the ceramic. We continue to improving our process and utilizing the newest technology available in our industry.

Water Glass and Silica Sol Investment Casting: Water glass and Silica sol casting make china casting industry special all over the world. The main differences are the surface roughness and the casting price. Most foundries made casting our of water glass process in China 10 years ago. Only few casting foundries change to silica sol process nowadays. However, we keep both processes and make more options for our customers.

Water Glass Investment Casting Method: We use domestic wax and dewax into high temperature water. Most importantly, ceramic mold material is water glass quartz sand that is very cheap locally. Therefore, the surface finish and the accuracy of the casting will not be that good. But it is still weight better than sand casting process.  

Silica Sol Investment Casting Method: We use high temperature wax and dewax into flash fire. Meanwhile, ceramic mold material is silica sol zircon sand that is more expensive than quartz sand. Therefore, the surface finish and the accuracy of the casting will be very impressive. Silica sol investment casting is our main production line right now.

Vacuum Casting: Vacuum casting capability makes it special to you. We can make quality and complex castings by our vacuum furnace with low price. The only one difference between normal investment casting and vacuum casting is pouring process. In order to achieve optimal casting properties, we have to pour the metal into vacuum furnace. We melt high nickel alloy or supper alloy and pour the metal by evacuating air in an enclosed area. As a result, we can achieve complex and difficult castings successfully.

Cast Iron Casting Suppliers | Machined Iron Casting Manufacturers

In manufacturing facility modern technology there are a number of kind of metal dispersing's, among one of the most typical treatment is that molten steels are poured inside mold and mildew and mildews made of casting sand and when the metal has in fact enhanced they are removed from the spreading's. Frequently the spreading out sand is water based or oil based. The water based sand casts are in addition referred to as environment-friendly casts, which are made by combining wet combination of clay and sand.
There are various type of shops as well as each of the factory might use information or combination of different type of factory devices in addition to factory items. The iron for example might use blast heating system which is additional normally called as Cupola. Bronze and brass shops could Ductile Iron Casting usually have gas warmed heater or electrical induction heater. Shop tools in addition to items may additionally consist of machinery along with resources such as shot molding or investment casting gizmos. Investment casting is likewise commonly described as shed wax dispersing. In this therapy, usually wax as well as various other thermoplastic materials are made use of making various type of manufacturing facility products.


There are a lot of factory networks that use huge job chances to multitude of skilled experts. A lot of the manufacturing facility functions could contain proper post as engineers, manufacturing facility professionals, auditors, functional heads and also different other profitable placements.

There are numerous sorts of equipment and also products that are commonly made use of in the process of steel spreading, economic investment casting, die casting and also many other sorts of factory spreading's. The majority of the tool's and materials include a broad gamut of molding devices in addition to combinations, heating systems, service providers, ladles as well as large supply of steels and alloys, chemical binding products, unique kinds of sand dispersing's, abrasives ingredients as well as filters.
These shop devices' in addition to products additionally consist of a collection of enhanced strategies along with machinery that are needed to satisfy the work of steel dispersing. The normal procedure of steel dispersing includes melting steels in furnaces then placing the hot molten steels right into the steel cast to supply it the desired kind or create different sort of products. The shop products may consist of significant supply of chemical materials which are widely made use of to hold together numerous type of alloys in addition to specialty sands to produce the molds.
This special selection of sand is called as environment-friendly sand as well as they are usually used in a great deal of plants as it is particularly developed to maintain the form much better compared with common sand. A steel foundry could be focused on creating store products of a certain steel or have one-of-a-kind heating systems as well as numerous other foundry tool's and items which are significantly established for the particular procedures.
There could be various other factories that may manage manufacturing facility spreading's with use various sort of steels and alloys, which may consist of substantial series of iron foundry, zinc store, lightweight light weight aluminum factory, bronze foundry, copper shop, brass shop along with a lot more.

OTTOMMO Casting: China Casting Metal Foundry & Precision Casting Foundry

Investment casting is one of the oldest known metalworking processes in existence. Beginning more than 5,000 years ago as "lost wax investment casting" the historical process used bee's wax to form a pattern which was then used to create various components and products.

Fast forward to today, thousands of years later and the science remains the same. However, investment casting foundries all over the world have introduced new innovations such as high-tech waxes, advanced refractory materials, and the many advances made possible by computers and computer aided design.

Similar to the results of our ancient ancestors when they did it, casting provides unparalleled accuracy, repeatability, and quality -- this makes the investment casting of small parts and large parts in high quality alloys a fantastic alternative to other less precise fabricating.

.

The investment casting process begins with a design. This can be a drawing or an existing prototype part. The next step is mold making. From a drawing, design, or prototype theinvestment casting foundry produces an injection mold. This wax pattern injection mold is then machined using computer assisted design and/or computer aided manufacturing, a marriage of both ancient science and cutting edge technology.

Sand casting is one of the oldest processes. As the name implies. a fine form of sand is used as the mold. Metal is poured(gravity feed) into the mold. After the material has cooled, the frame is released and the sand falls away. Leaving the parts to be ground and cleaned. This type of casting is the most rudimentary of all. But it has a tremendous advantage. This is the least expensive and maybe the only way to make large castings. Castings that weigh 50 lbs., up to thousands of pounds are made using this method. Compared to sand casting, this process yields a more precise, complex component. IC process has been used for hundreds of years to make jewelry. To make an investment casting, a tool is machined out of aluminum. Then wax is injected into the tool. The tool then produces a wax model that is an exact replica (with some allowances for shrinkage) of the part to be made.
