Sand casting is among the most preferred methods for casting techniques. This method is also the simplest and practical casting technique. During the process, the material used for casting is transferred into the casting sand. The molten metal is filled into the cavity and the casting material becomes an integral part of the product. Once the casted material cools down, it is removed from the sand. With this process, a product is obtained in accordance with the original design.
To get the best result during a complex casting process, one should use good quality casting sand.
Investment casting is a procedure that allows the casting of parts that are hard to produce at the desired quality. It is a technique that accelerates prototype studies and mass production. Thanks to this method, parts with smooth surfaces can be obtained with minimal processing cost.
Investment casting refers to the extraction of the wax material from the mold after its encapsulation in ceramic, followed by the pouring of molten metal into the mold. This method is ideal for the production of small and hard-to-cast parts. Many metals, such as steel alloys, aluminum and stainless steel, can be used in investment casting.
The problems in the global supply chain that emerged during the pandemic have elevated the importance of domestic production. Recent developments have helped increase the yearly average growth of the metal casting sector since 2011 to 7%. According to data shared by Turkish Foundry Association (TÜDÖKSAD), the export volume of the member companies operating in the sector is calculated as US$4.1 billion. The resulting volume places Türkiye in ninth place in terms of global casting production.
Gedik Casting continues its production at full throttle, serving many sectors ranging from automotive to defense, and from agriculture to energy, with its experience of 54 years. Welding of parts weighing 1 to 35 kg is possible on the FBO green sand molding line of the Hendek production facility in Sakarya, which is the largest integrated casting factory in Türkiye. The capacity of the FTL Alphaset resin line in the casting factory, which covers an area of 25,000 square meters, ranges from 5 kg to 2.5 tons. Carbon, stainless and duplex stainless steels can be used in these lines. In addition to these materials, high chrome castings, nodular pig and gray cast irons, and bronze can be processed for part production.
Gedik Welding carries out rigorous sand casting and investment casting operations within its advanced casting technologies plant, which covers an area of 6,000 square meters. In the plant, wax injection operations are carried out through two horizontal and five vertical wax pincers. On the ceramic line, on the other hand, four continuous and controlled ceramic baths are complemented by one sprinkler and two fluidized beds. The facility, which operates with ISO-9001, IATF-16949, AD 2000-W0, Türk Loydu, DNV-GL and RINA certificates, focuses on the production of many parts in accordance with the DIN10293 standard. In addition to off-the-shelf casting products, we offer R&D and project adaptation support to clients, drawing upon the knowledge of our specialized staff.
