Istanbul Dokum is an organization, has flexible production methods enable to cast, iron, nodular iron, steel, stainless steel, duplex, super duplex and bronze in sand molding system in a single foundry. Our foundry, as different from the hundreds of foundries across Turkey and Europe, complex is equipped to supply castings to customers. In our induction furnaces, your orders are casted carefully with our qualified personnel. Casting cleaning is carried out by a separate team within our structure and some parts are subjected to heat treatment in accordance with special demands. We apply heat treatment in order to achieve better mechanical values depending on the end use areas. Sandblasting is done in our 2500x2500x3500(h)mm inner dimensioned sandblasting machine with a single piece capacity of 10 tons.

Our range of products includes welded charging aids such as guide grids, charge carriers, tempering baskets, traverses, basket inserts, wire mesh baskets, charging baskets, heat-resistant workpiece carriers, as well as hardening boxes for the heat treatment of steel or other metals. good strength properties at high temperatures Continuous operation in air up to approx. 1150 ° C with temperature changes up to approx. 1000 ° C perfectly suitable for heat treatment We use according to customer requirements .EN 1.4845 / AISI 310S .EN 1.4841 / AISI 314 Both materials are heat-resistant steel. Due to the higher chromium and nickel content and have a good resistance to oxidation. The good strength properties are still present even at higher temperatures. Both also have excellent chemical resistance up to 1100°C.

Pallet dolly (Tugger trains) have a robust welded steel construction and are equipped with 4 catch corners. The surface of the trolleys is galvanized or powder-coated, has permanent surface protection and is impact and scratch resistant Swivel and fixed castors: polyurethane tires, hubs with deep groove ball bearings, brakes on the swivel castors, in accordance with the European standard EN 1757-3. Housing galvanized. Standard wheels for medium loads. Quiet running, spring-loaded drawbar.

Our foundry has it's own engineering and design team including a pattern shop with CNC Router for producing own patterns. 3D design and analyze softwares are professionally applied into the castings. Induction melting is done with double ladle furnace and Alpha-set moulding line is used with reclamation unit. When casting is done, heat treatment and shot blasting could be done within the facility. Our lab consists main test equipments such as spectrometer, metal microscope, mechnical testing machines and also sand test equipments. Mainly our productions are medium-high alloyed steel castings, heat resistant refractory steels and stainless steel from small to large volumes with un-machined or machined conditions. We supply casts to industries such as construction, oil & gas, cement, mining, energy, iron & steel, pump, valve, defense, railway, heat treatment etc. and casting pieces from 1 to 60 kg with automatic moulding line or 60 kg to 1.000 kg with manuel moulding.
