                 WHAT IS INVESTMENT CASTING

                              Investment casting is a manufacturing method in which wax copies of the designed part are created and then these copies are coated with refractory ceramics, and molten metal is poured into the mold produced. In the process, the part that is desired to be poured first is designed and wax injection mold is designed. The wax model of the piece to be produced by wax molding is made. For this process, the melted wax is injected into the aluminum or steel mold with injection presses and the wax model is obtained. The wax models produced are lined up on the main sprues designed according to the material, and they are immersed in the ceramic bath to start the coating process. The chemical composition and thickness of the ceramic coating changes according to the geometry and alloy of the part. It is processed in drying rooms with humidity and temperature control. This process is repeated until the required shell is obtained. After the ceramic coating process is finished, the wax inside the clusters is evacuated under the factors of temperature and pressure, and the ceramic shell is emptied. The inner geometry of the ceramic that is emptied takes the shape of the material to be poured. The molds are sintered and made resistant to the temperature and pressure of the molten metal. The metal melted in the induction furnace is poured into preheated ceramic molds. After the metal has cooled and solidified, the ceramic shell is broken and the metal parts are separated from the runner. The runner connections in the separated parts are sandblasted and the designed material becomes ready.

           PRECISION CASTING ADVANTAGES

• Specific parts that are difficult or impossible to manufacture with conventional casting methods and machining could be produced using the precision casting method.
• It is possible to obtain maximum surface quality and measurement precision that cannot be done with other methods.
• Parts production from 3 gr to 150 kg can be made with high quality.
• Mold separation lines formed in the parts produced with the traditional casting method are not formed owing to the use of one piece mold in the precision casting method.
• Casting of various alloys is possible in the precision casting method. The materials with the desired chemical composition can be produced.
• In addition to the low cost and long life of the prepared molds compared to other molds, the costs are greatly reduced as a result of minimizing machining too.
   

          INVESTMENT CASTING HISTORY
         The precision casting method is known as "Investment Casting", "Ceramic Shell Casting" (ceramic shell casting).The investment casting method is also called "disappearing wax" and its history dates back to ancient times. The reason why the investment casting method is called "lost wax" is due to the formation of a mold by first shaping the wax model of the part to be cast and then coating it with a heat-resistant material, and the melting of the wax inside it by heating the mold. The oldest known resource in the precision casting method (Schedula Diversarum) is a resource by a monk who is a member of the Theopilus Church board, describing precision casting, how it is made and its application, providing information about the production processes. The historical Medusa statue produced by investment casting method was produced by Benvenuto Celini in Italy.

         The precision casting method entered a modern industrial period towards the end of the 19th century and began to be used in the field of dentistry. In 1901, American-based dentist Tagart produced the filling material using precision casting method. After filling the hollow tooth cavity with wax and making a correction by giving it its original shape, taking the wax model, burying it in a heat-resistant filling ceramic and removing the wax inside it, it was in the form of flowing metal into the remaining filling cavity with unknown air pressure or using a centrifugal force machine. For this reason, the use of precision casting method in dentistry and jewelery is also known as "centrifugal casting". Today, precision casting method is used in almost every industrial area where metal part production is required. It is easily used in the production of electronic parts, microwave ovens, trigger, gun, rifle bodies, binoculars and similar parts.
