5. Other products and services
Our experience in stamping and tubing allows us to develop small tools for internal use and for our customers.
We offer surface protection in three variants: zinc, zinc-nickel and tin coating.
We provide services of coordinate measuring and different chemical tests in our lab.

6. Technology Stamping Cold forming Turning Milling Eroding Brazing
Surface protection
Springs production
Thermal treatment

7. Stamping
More than 40 excenter and hydraulic presses ranging from 10 to 400 tons allow us to produce different stamped parts. Stamping presses are primarily used for production of covers which are then assembled into cover assemblies. Materials used are steel and stainless steel.

8. CNC machining
More than 20 CNC machines produce sub-components which are assembled into cover assemblies and final products which are then delivered to our customers. Capacities allow us to produce parts from ferrous and non-ferrous metals.

9. Tubing
Tubing involves different processes such as cutting, chamfering, deburring, reaming, cold forming and bending. Different types of tubes produced from steel, stainless steel and aluminum are used in cover assemblies, but also as final parts which are assembled into Common Rail Pumps and Coolers by our customers.

10. Assembly and brazing
Sub-components are assembled into cover assemblies and brazed in brazing ovens with temperatures up to 1100° C. Brazing ovens are dedicated to steel and stainless steel parts.

11. Tool room
Tools for tube forming and bending, stamping, plastic die moulding and gauges for the running production are produced in our tool room. Tool room capacities are also used for maintenance of the existing stamping tools. Processes include turning and milling, CNC milling, coordinate grinding, centerless grinding, EDM and wire-cut EDM and heat treatment. Tool room provides services to customers as well.

12. Production of springs
At it‘s foundation, Saraj-Komerc was producing primarily springs. Even though it makes a very small portion of our current production, spring manufacturing is still one of our specialities. We produce all types of springs from material ranging from Ø0,2 to Ø16 mm in diameter. Springs are produced from patented steel wire and from stainless steel wire. Production includes galvanizing and passivation of springs. Springs are tested internally for force and deflection.

13. Production of hinges and springs for garage doors
We provide services of production of hinges and springs of different dimensions for garage doors. Our offer includes springs produced from matertial ranging from Ø5 to Ø12 mm in diameter, and in different lengths.
Springs are delivered oiled and packed in a stretch foil, in accordance with our customer requirements. Materials used are imported from the EU countries. Material certificates are delivered upon request.

14. Galvanizing Three galvanizing lines.
Two galvanizing lines are allocated for Zinc and Tin galvanizing.
Third galvanizing line which is fully automated is used for Zn/Ni galvanizing, which is widely used in the automotive industry.

15. Coating Zinc Acidic and alkaline galvanizing Tin
Coating thickness distribution is good, with decorative appearance obtained.
Zn/Ni
Zn/Ni coating can in terms of salt spray test according to ISO 9227 reach following values:
- more than 500 hours to white corrosion,
- more than 1000 hours to red corrosion

16. Waste water treatment
Waste water treatment lines are automated facilities where output results meet regulations for output parameters such as concentration of heavy metals or pH value.
Measurements are read online and present real time values.

17. Quality and ecology 2002 ISO 9001:2008 2007 ISO 14001:2004 2015
ISO TS 16949:2009

18. Measuring equipment and devices
We have the following measuring instruments:
CMM (3D Coordinate Measuring Machine),
Rroughness measuring machine,
Contourograph,
Shadowgraph,
X-Ray for measuring surface protection thickness
We have all the equipment necessary to assure quality required by our customers.

19. Social responsibility
Our strength is that as a socially responsible company we create conditions for more pleasant and local communities. We are active in humanitarian actions and sponsorships that improve quality of life in local community.
