Closed die forgings - Import export

At Extra Forge d.o.o., we also specialize in the closed die forging of aluminum. We can forge products from any aluminum alloy, with weights ranging from 0.05 to 6 kg. Our company prides itself on having professional associates who were among the first in the region to forge aluminum products, a process distinct from steel forging. Our advanced technological processes for die forging aluminum semi-finished products allow us to achieve an accuracy of ± 0.2 mm, ensuring precision and quality in our forgings.

To meet the requirements of our customers in the manufacture of close-die forgings we operate five maxi-press lines (750 ÷ 4,000 tons) equipped with induction heating and automatic temperature control. Weight: 200g ÷ 26 kg

With press capacities between 15 and 500 MN, Siempelkamp's closed-die forging presses oer the optimal solution for numerous application areas. The optimal relationship between press dimension and press force oers our customers maximum benets. Best process and system parameters are the guarantee for high dimensional and repeat accuracy. Siempelkamp supplies hydraulic closed-die forging presses for many dierent application areas. According to the application area, guidance accuracy, cycle time, eccentricity, and speed are optimally adjusted with one another. Depending on the customers' requirement, Siempelkamp's closed-die forging presses are available in dierent designs - as push down and pulldown presses. If desired we can supply these presses as part of a complete solution, from the press segment to the forging plant.

Extra Forge d.o.o. is a leading production and service company specializing in closed die forging of various types of steel, including stainless steel, high and low alloy steel, and carbon steel. Our expertise lies in the hot forging of steel semi-finished products ranging from 0.1 kg to 8 kg. This process enhances the strength and toughness of the products compared to other manufacturing methods. The advanced technological processes at Extra Forge d.o.o. enable us to achieve forging precision up to ± 0.2 mm, ensuring high-quality and reliable products.

Gears are mechanical components and an essential part of many machines and are used in everything from piston engines to gearbox construction to agricultural machinery and wind turbines. Main gear types are: Spur and Pinion Gears: These gears have straight teeth and are the most common. They transmit rotational movements parallel to the axis and are found in gears, clocks and machines. Bevel Gears: These gears have tapered teeth and movement between non-parallel axes. They are used in differential gears of vehicles and in industrial machinery. Worm Gear: This combination of worm and worm wheel provides high gear ratio and is used in hoists, conveyors and other applications. Hydraulic The West German drop forge KB Schmiedetechnik GmbH produces forged gear blanks, piston parts and hydraulic components for a wide range of applications - from agricultural machinery and conveyor technology to engine construction, diesel generators to shipbuilding.

KB Schmiedetechnik GmbH is a drop forge in West Germany, located between the historic “blade & metal region” Solingen and the “soccer city” Dortmund, specializing in small series production of safety-relevant closed die forgings from 200g to 130Kg unit weight of all steel grades and alloys according to following certifications and standards: pressure equipment: valves, boiler systems, piping PED 2014/68/EU, AD 2000-W0, ASME/ASTM, CNIM, Alstom, MHPS nuclear power/ atomic energy and plant construction KTA3201.1, KTA1401, AVS D 100/50, Siemens, EDF/Areva/RCC-M naval architecture/ shipbuilding and offshore/ ocean engineering, certified by • American Bureau of Shipping (ABS) • Bureau Veritas Marine & Offshore(BV) • Det Norske Veritas (DNV) • Lloyd´s Register (LR) • Nippon Kaiji Kyōkai (ClassNK) Examples: components and equipment like brackets, holders, chain links, hoists, lifting hooks, fasteners, pressure-bearing parts like valve bodies, pipe connections, gearwheels, ...

KB Schmiedetechnik GmbH is a highly certified West German drop forge, located in Hagen (Westphalia) - between the historic "blade & metal" region Solingen and the "soccer city" Dortmund - specializing in small series production of safety-relevant closed die forgings from 200g to 130Kg unit weight of all steel grades including duplex stainless steels, nickel based and titanium alloys. Examples are forgings for mechanical applications like brackets, holders, hoists, forged lifting gear, slings, hooks, chain links, special screws, nuts, gearwheels/ toothed/ cog wheels, forged pinions, and pressure parts like forged valves for hydrogen production and nuclear energy, as well as forgings for boiler systems construction. These include forged parts for boilers and piping like fittings, flanges, bifurcations, hose pipes, and forged boiler parts like header caps, end pieces, manifolds. KB Schmiedetechnik produces forgings for high pressure applications according to ASME, PED, KTA, RCCM.

Forgings have a grain flow, like the fiber structure of wood, caused by plastic deformation during the forging process. Proper orientation of grain flow improves the physical properties of forged parts. Everyday examples for forgings are car wheel bolts or screw nuts. Further examples include all kind of fasteners and hoists including forged hooks, eyebolts, and chain links. Forgings are also part of complex assemblies like crawler track chains, articulation sockets for busses or trains, hydraulic systems and lifting gears, as well gearwheels (forged blanks), pinions, rollers, holders and supports. Made in Germany of European primary material KB Schmiedetechnik GmbH is a Western German drop forge, specialized in small series production of closed die forgings from 200g to 130Kg unit weight and up to 600mm length of all forgeable steel grades and superalloys according to: ISO 9001 + ISO 14001 ASME, PED, KTA, RCC-M ABS, BV, ClassNK, DNV, LR
