Karaman Döküm was founded in 1952 by Karaman family. In 1967 Hayrettin Karaman took over the business and brought it today as a family business. From 1952 to 1968 the company was casting pipes for construction firms. After 1968 the company started to produce blocks for elektricity motors,  spare parts for various machines including automotive and agricultural machines in casting industry. In 1989 by taking and founding  the first induction furnace Karaman Döküm added new products to its portfolio, like GG & GGG cast-iron products and some other alloy castings. Both the factory and the main office was in İstanbul until the formation of the new foundation in Düzce (see the photo on the right) in 1998. Plant is founded on 3,500.-m2 covered area in 13,000.-m2 land.

FOUNDRY
Melting & Production:
Two induction furnaces with 1,000.kg and 1,250.kg capacities forms the melting unit.
GG & GGG cast-iron production involves parts from 100gr to 2,000.kg.
Annual capacity is about 4,000.tons, and casting can also be made in this amount.
Core Production:
Upto  50lt. cores are produced in core machines with Cold-box, hot-box and shell-core systems.
In cleaning cast-iron unit there are one hanging shot blasting system with 1 ton capacity, one tumbler shot blasting machine with 1 ton capacity and pedestal grinders.
All products coming form moulding unit are sanded, grinded, cleaned for crusts, controled for quality and painted here. After these steps cast-iron products are getting packaged and moved to the delivery barn.

QUALITY CONTROL
Products are being controled step by step from the purchase of raw materials up untill the delivery of finished goods.
When the raw materials are melted, the character of required material is being tested with instruments like thermal analysis, chemical analysis, heat measurement, hardness measurement and metallurgy microscope;
When they become semi-finished goods they are tested for the material’s endurance with instruments like pull & pressure measurement, leakproofness & liquid pressure tests. And samples are being taken periodically from finished goods to compare them with the technical drawings’ sizes like height, weight, etc and to approve the products for delivery.
