Production
Production takes place on modern production lines using automatic cold forming (double blow headers, to transfer headers to 7 stations) automatic and semi-automatic multiple stroke hot forging machines. We produce all kinds of products in standard and non-standard dimensions, and are equipped for OEM production according to special customer requirements. We have our own chemical descaling and phosphate coating for raw material wire and bars, drawing machines, shot blasting, annealing and normalization equipment, cold and hot forging, thread rolling, stamping, grinding, milling, heat treatment and case hardening facilities. Our surface protection includes hot dip galvanizing and zinc plating with different passivation. We produce parts for machines and assemblies utilizing sheet metal plates using laser, gas and plasma cutters. The parts are then finished on CNC bending machines, hydraulic and excenter presses and by merging of complex 3D shapes with cold bending and welding. Universal mechanical elements are produced on CNC machines and machining centres. Our primary production is based on DIN, EN, ISO, ANSI and UNI standards.

Quality Quality control In order to recognize and meet the expectation of customers, DIV fastener factory has certified its own quality control system according to ISO 9001:2008. In the last year we changed the certifying authority and have joined the TÜV group, primarily due to range of services they offer, apart from the system of quality control and system of technical certification according to technical standards. Recognizing the needs of the market and following regulatory requirements and EU directives, we are currently certified for key standards tied to the European directive for construction 305/2011 and equipment under pressure PED 97/23. •
EN 15048-1 and 2:2007 Non-preloaded Structural Bolting Assemblies
•
EN 14399-4:2008 High strength structural bolting assemblies for preloading – part 4: System HV – Hexagon bolt and nut assemblies (EN 14399-4:2005)
•
EN 14399-8:2008 High strength structural bolting assemblies for - part 8: System HV Hexagon fit bolt and nut assemblies (EN 14399-8:2007)
•
PED 97/23/EC Pressure equipment directive, for screw assemblies
The certification of products according to the mentioned standards is a requirement of European directives and domestic legislation and a great assistance tool for all equipment manufacturers to adhere to standards. Products manufactured according to mentioned standards in compliance with European directives are also accompanied by Declarations of Performance, labeled with CE marks, so that every manufacturer can install them into their own final product. We are additionally certified for EN 150852:2008 Railway applications – Welding of railway vehicles and components – Part 2: Quality requirements and certification of welding manufacturer (EN 15085-2:2007) allowing us to attain the right to manufacture steel construction for railway vehicles. In the same market sector we also have certification from Deutche Bahn AG for retaining rings for railway accessories. Our focus on the automobile industry has resulted in adopting the demands of the standard ISO TS 16949 in our own processes

RECENT
Investment
The most modern factory of standard fastener products and the largest investment in this part of Europe. The opening of a new factory, valued at 25 million euros, represents one of the largest investments in the wider region. Annual production capacity of the new factory is 100,000 tons, which would increase export from current 20 million to 100 million euros. The new factory is located on the site of an existing industrial plant and covers more than 22,000 square meters of production and handling space. With this new investment we intend to achieve mass production of standard fastener products, especially ISO 4014, ISO 4017, DIN 931 and DIN 933.

storage capacity of raw materials is 10,000 tons the wire is annealed in chamber furnaces with capacity of 300 tons per day. Prior to forging and rolling wire is cleaned by shot blasting or chemical methods. Machining – forging and rolling – is carried out on 23 lines of machines, with additional 14 lines for thread rolling, with a total capacity of 100,000 tons per year. Heat treatment is carried out by hardening and tempering of fasteners in flow furnaces with protective atmosphere, with a capacity of 7.5 tons per hour. Anticorrosive protection – we use all kinds of surface protection, such as electroplating and galvanizing, hot dip galvanizing, decorative surface protection, highly corrosive resistant surface protection and protection for reduced friction twisting. In these processes, ecological products without negative impacts of Chrome (VI) are being used. Protective coatings meet the requirements of REACH and RoHS and do not adversely affect the environment. Galvanic protection uses galvanizing technology in the alkaline electrolyte, which, with the use of environmentally friendly chemicals, reduces emission of heavy metals into the environment and provides a steady coating of zinc. After galvanizing process, the screws are varnished in centrifuges, which increase corrosion resistance up to ten times compared to standard requirements. The capacity is 9,6 tons per hour. packing is equipped with 6 semi-automatic packing facilities with a capacity of 8-10 tons per hour. properly packed products are stored in the high rack storage with a capacity of 8,900 pallet places, while 13 loading ramps are ready and waiting to load goods from Knin to all corners of the globe.
