Mechanical Production Activities

BEST Mechanical Production Unit is conducting business in Balikesir Industrial Zone on a 5500 m2 closed area with 160 blue and white collar employee. Our team consists of experienced Mechanical / Welding engineers and Industrial/Mechanical technicians who has been working in a team sprit.

In Mechanical Production Unit, we are producing mechanical equipment for distribution and power transformers. The scope of our main production are :

  1. Core Fixing Steel
  2. Conservators
  3. Covers
  4. Tanks
  5. Piping
  6. Cable Boxes

Raw materials are being prepared in Pre-Processing Department with state of art CNC controlled machines. Raw materials being used are:

Steels in accordance with DIN EN 10025-91 and TS 2162
Steels in accordance with EN 10130 St-12
Stainless Steels in accordance with DIN 17441 1.4301
Steel Piping in accordance with DIN 2448

In this department, BEST is conducting;

Oxygen and Plasma cutting
Shearing
Punching under press
Bending
Cylindrical folding
Punching
Lathe operations
Milling operations
Planing
Threading
Marking
Blasting before welding

All metal parts produced in Pre-Processing Department are welded as per specification in “Assembly Department”. Our welding procedures are in accordance with ISO 4063 –135. We are also capable to apply procedures in accordance with ISO 4063 –111. All pins are welded with Pin Welding machines.

All welding are tested with penetration method in accordance with EN 571-1. In case of request, we are also capable to make testing done with ultrasonic and radiographic methods with external suppliers.It is worth to mention that the records of BEST shows that the records of leakages of BEST are at ignorable levels.

All welding personnel have the competency certificate in accordance with EN 287-1. Competency tests and examinations are being repeated every two years by TUV Germany. In addition to all, all our welding personnel is regularly being trained within the organization and with external training programs to increase their competency.

In our state of art facilities, all dangerous gases are emitted with Plymovent central emission system operating at eye level to cancel any risk to our employees. All these gases are then filtered in our exhausting system to minimize impacts to the environment. In this regard, our records shows that the level of gases exported to the environment are much more less than the levels allowed in the standards.

We are also capable to get hot dip galvanizing done in case of request for all distribution and power transformer up to certain dimensions.

Following welding, “Surface Processing Department” takes the lead to complete the process with surface preparation and painting. In this process, all mechanical part having more than 4 mm thickness is blasted in accordance with
EN ISO 1294. Lower thickness are blasted with flap disk and if required with chemical cleaning process to minimize the risk of damage to the surface.

Following blasting and cleaning process, all material parts are phosphated and painted. To proceed with painting, BEST applies three main standard applications unless otherwise stated in the specifications:

(N) Type : Standard atmospheric conditions
(T) Type :  Tropical climate, heavy industrial conditions
(S)Type  :  Tropical climate, sea level salty conditions and heavy industrial conditions

In our facilities, all the processes are monitored, conducted and followed through ERP system. Quality check points are clearly defined and followed by experienced quality engineers and technicians.
