Foundry is one of the most important branches of industry that has been used for centuries to process and shape metals.
In every stage of our daily life, materials produced by casting method are used in many different areas from jewelery to heavy industrial looms, from agricultural machinery to ship machinery. Many industrial enterprises have foundries.
foundry industry and craft in Turkey during the period of industrialization with deep-rooted historical background developed with private investment in Europe, and has reached an important point in the world.
Turkey foundry with a nominal figures for 2010. Germany, followed by France and Italy in Europe is settled in 4th place among the world’s leading foundry manufacturers have continued to rise. The sector ranks 13th in the world ranking in 2010.
Production Methods and Technology:
Cast iron by melting various pig iron, metal scraps and ferro alloys in iron and steel casting industry, electrical induction, arc or cupola furnaces, shaping them in sand, ceramic or metal molds prepared in molding facilities and gaining different mechanical properties with special heat treatment, It is a sector that produces steel casting, nodular cast iron and tempered casting products as raw casting, processed casting and finished products.
Similar methods are used in casting of non-ferrous metals, and high speed and efficiency pressure casting methods are rapidly developing in the production of aluminum and zamak parts.
The metal casting production method was grouped with 273 codes in the International Standard for Industrial Classification ISIC Rev.3 and Rev 3.1. With the amendment made in 2008, ISIC Rev.4 was published and the metal casting industry code was determined as 243. Code 2431 covers iron and steel casting and Code 2432 covers casting of non-ferrous metals.
It is possible to summarize the production methods used in the casting industry as metal melting, sand preparation, core production, molding, cleaning, heat treatment, grinding and coating processes.
Casting production method is one of the basic elements of industrial production and organizations that produce with this technique are divided into two. The first part is the organizations that produce cast products completely in line with customer demands, and the others are those that produce by casting method for the materials they use in their finished products (for example, there are zamak foundries of lock and zipper manufacturers, aluminum foundries of electric motor manufacturers). Some facilities, on the other hand, deliver what they produce with the casting technique to the end user as a final product after final processing. Examples of these are products such as radiators, alloy car wheels, door handles.
One of the most important features of foundries is that they can modify their production according to market demands. For example, a facility that manufactures and sells cast iron bathtubs may direct its production line to stove and fireplace parts casting as this market shrinks, and if this market shrinks, it may turn to automotive parts casting.
