PREPARATION OF RAW MATERIAL
Raw material supply, which is one of the most important stages of production, is provided only from Turkish or European steel producers with ISO 9001 and / or ISO TS 16949 certification.
The chemical, dimensional, visual and mechanical properties of the raw materials are meticulously controlled by our quality team before the raw material is accepted. Raw materials; based on customer requests; It is supplied from tempered steel and stainless steels in accordance with ASTM grades or required mechanical values in the norms 4.6 / 4.8 / 5.8 / 5.6 / 6.8 / 8.8 / 10.9 / 12.9.
Preparation of raw materials whose acceptance processes are completed, calculated lengths on their technical drawings, by our educated personnel, in cutting machines with the latest technology used in the sector is made with the desired Quality and Sensivility.
BIRIKIM with the occumulation of knowledge is forged BOLTS of different diameters and lengths up to M100mm and 1500mm long in hot forging bolts makers. During the process of hot forging by measuring the material temperatures instantaneously, managing the process and producing high quality products are provided.
Rolling Machines are produced bolts up to M130mm in required diameter also studs and anchors in required lengths up to M130mm with expected quality and precision.
Used in threading process the Rollers are procured from suppliers that manufacture using the latest technology.
Different types and diameters of pins, bushings in addition to the products, special machining parts are also produced on CNC machines.
The Depatment of Machining with its own production line is produced of other dwg parts with high added value.
All fasteners for which required surface sensitivity are produced in grinding machines, products up to 80 mm in diameter and up to 300 mm in length.
Grinding processes have surface roughness capability up to Ra0,02 precision.
Fasteners and Machining parts, in order to supply the standard or optional strength values are done to heat treatment process. The temperature , time and atmosphere controls of Tempering , Heat Treating, Cementation , Nitration, Induction are done automatically. In Heat Treatment process (product surface-core hardness, crack control and thread surface hardness, etc.) determined by the standards are performed and recorded by the quality control personnel. To DIN 898-1, ASTM, EN 10209 Standards 4.6, 4.8, 5.6, 5.8, 6.8, 8.8, 10.9, 12.9, QT Heat Treatment process are done.
In addition to protection from external factors such as abrasion, corrosion, decay and aesthetically, coatings are also important in the production of bolts. We can offer the following coating services according to customer needs and demands.
1. Zinc Lamel Coating:
Dacral: Geomet, Dacromet
Dörken: Delta Tone, Delta Seal
2. Electro Galvanize
Zinc Plated Yellow Passivation, Silver Passivation, Blue Passivation
*In our Electro Galvanizing facility, we have a hydrogen embrittlement furnace to prevent acid cleansing during the coating process or to prevent hydrogen embrittlement (brittleness) that may occur during the coating process. Necessary salt spray tests can be performed according to customer demand and the results are reported and shared with the customer.
3. Hot-Dip Galvanize
3.1. HDG ISO FITTING
3.2. HDG OVERSIZED
4. Zinc-Manganese Phosphate Coating
5. Bolt Locking Systems (3m 2353 blue, 3m 2353 yellow, Precote 80,85 Coating)
6. Teflon Coating
