Trays for battery cells
The core of our business is the production of battery trays. The trays are manufactured from sheet metal and they are usually covered with a seamless plastic coat. This layer of plastic not only provides reliable protection from corrosion, it works primarily as perfect insulation of the incorporated electric cells from the trays. The plastic that coats the tray is acid-resistant in case the battery has suffered mechanical damage.
CNC plasma cutting technology, thanks to its physical properties, delivers precision cutting with an emphasis on being able to modify the cut quality. With lower requirements as to the cut surface quality, the cutting process may be accelerated, which results in a lower price of the service.
Sheet metal punching
We use a punching press (60 ton). This operation may be applied in S235 black sheet metal for hole dimensions up to ø57 x 8 mm.The machine may also be used for shape cutting along the edge of the sheet.
We use the MIG and MAG welding methods. We are ready to weld carbon steel, stainless steel, aluminium and aluminium alloys. In September 2009 we successfully competed for a certificate DIN 18800 – 7:2002-09 Class D for light steel structures made from carbon steel.
CNC sheet metal bending
We use a press brake (120 ton) for bending. Parameters of metal bending.
|Material||Bend length||Maximum thickness|
|Carbon steel||3000 mm||4.00 mm|
|Carbon steel||2000 mm||6.00 mm|
|Stainless steel||3000 mm||3.00 mm|
|Aluminium||3000 mm||5.00 mm|
If necessary, we are able to use CNC cutting with pieces up to 200 mm thick.
Sheet metal cutting
We use a hydraulic cutter for orders of processing usually black metal sheets with a thickness up to 8 mm and a cut length up to 2,000 mm.
Our machining plant is equipped with several types of machines.
- Lathe: Workable length 1,250 mm, maximum workpiece diameter 380 mm
- Universal Mill Cutter: Table dimensions 250 x 1,250 mm
- Band Saw: Vise jaw maximum distance 240 mm
As we process sheet metal, for the most part, we use the materials and consumables given below:
We usually process quality S235 J+AR sheet metal with thicknesses from 2 – 10mm usually in these formats:
|1000 x 2000mm||4 x 819 x 3700mm|
|1250 x 2500mm||4 x 608 x 3700mm|
|1500 x 3000mm|
|2000 x 3000mm|
We process dozens of tons of sheet metal every month. Sometimes we need stainless steel (1.4301) and aluminium (AlMg3) material.
Profiles and bars
We purchase U-, L-, T-profile material and pipes. Our production uses these materials rather by the piece and their usage amounts to several tons per year.
3. GRINDING MATERIALS, WELDING MATERIALS (additional material, gases)
In terms of grinding material, we primarily use ø 115 or ø 125 mm disks. The material is welded using the MIG method. The additional material we use is Class SG2 welding wire with diameters of 0.8, 1.0, 1.2 mm. The inert atmosphere gas is prepared in our own mixing plant. The mixture contains argon – Ar, carbon dioxide – CO2 and oxygen – O2.
Personal protection or equipment
Gloves, shoes, work clothes, etc.
Each of our employees uses all the required personal protection and equipment they need. This refers to gloves, footwear, custom made work clothes, safety goggles, ear protection, etc.
