Description of ENCE GmbH production

ENCE GmbH production and engineering company is a coowner of the South Korean BUKANG machinery plant (Yeongcheon). Founded in 1986, BUKANG is one of the South Korean production leaders specializing in special parts, units and spare parts for various kinds of complex equipment used in different industries.

Bukang plant is a modern machine-building plant, having high precision equipment:

  • high-precision furnaces for steels and alloys melting;
  • centrifugal casting units and other casting equipment for precision castings (static methods of casting and investment casting);
  • pre-heating furnaces and heat treatment furnaces;
  • spot and arc welding units;
  • a large fleet of metal-working equipment (turning and milling centers, and machines with CNC, drilling machines, forging presses, various automatic saws);
  • modern laboratory and test equipment for the input and quality control of finished products (spectrometers, ultrasonic testing, hardness testers, stands for mechanical properties determining, etc.).

Bukang plant is located near Pusan which is a major South Korean trading port, which significantly reduces logistics costs when shipping goods to Europe.

In recent years ENCE GmbH and Bukang have developed a joint program of modernization of manufacture and business development, according to which the supply of products to Europe and the CIS countries is effected through ENCE GmbH, Bukang, in its turn, carries out the sale and shipment of goods to Asian countries as well as to Australia.

During many years, exchangeable parts and assemblies for various mechanical equipment, produced by this South Korean factory, have been supplied to large iron and steel works:

- ArcelorMittal (various countries), NipponSteel (Japan), NovolipetskSteel (Russia), Severstal (Russia), MMК (Russia), HyundaiSteel (South Korea), Kobesteel (Japan), U.S. Steel (Slovakia), CMI (Belgium), Cynk-Mal P.O. (Poland), and also to many others.

  • Component parts of screw-down mechanisms of rolling mills and assemblies;
  • Spindles and cardan shafts of drives of slow-speed heavy machines drives;
  • Rolls for hot and cold rolling mills.

Up-to-date equipment allows to perform high-precision machining for special parts having various levels of complexity, sizes and made of various materials:

  • turning;
  • milling;
  • horizontal boring;
  • Jig-boring;
  • gear milling;
  • gear shapingg;
  • spark erosion;
  • cylindrical grinding;
  • surface grinding;
  • internal grinding;
  • thread grinding and other machining.

Predominant thermal and chemical thermal processing techniques used to manufacture wide range of custom-made special-purpose parts are:

  • bulk hardening;
  • high-frequency current surface hardening;
  • surface carburizing followed by hardening;
  • nitriding.

The parts delivered by ENCE GmbH (ЭНЦЕ ГмбХ) are made in accordance with all relevant norms, fits and clearances, and based on our engineers’ vast experience in design and delivery of this equipment and are made of the following materials:

  • stainless steels and alloys 316L, 304, 316, Hastelloy;
  • special steels and alloys (heat-resistant, abrasion-resistant etc.);
  • stellen or equivalent alloys in terms of their physical and chemical properties;
  • copper-base alloys (alloys containing zirconium, aluminium, or multicomponent alloys such as bronze or brass);
  • ceramics;
  • composite materials (high-alloy stellen-, ceramic- or carbon-coated steel, steel with special local inserts made of these materials);
  • special ceramic materials based on zirconium oxides.

These parts find their application for machines and mechanisms of the following industries:

  • mechanical engineering
  • automotive
  • ferrous metallurgy
  • non-ferrous metallurgy
  • shipbuilding
  • chemical
  • Oil and Gas
  • medical
  • food
