The expert for steel blank production for battery containers with substantial knowledge in welding of steel containers of all types and in all shapes.


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.

Bent metal profiles

Our new press brake allows us to produce high-quality, sharp-edge and precise bending of sheet metal. We prepare sheet metal components of elevator cabins and various precision parts, as well as construction and fixation elements of various precision specifications.

Plasma cutting

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.

Oxy-acetylene cutting

CNC oxy-acetylene cutting acts as a full complement to plasma cutting. Orders that require cutting metal sheets 30-200 mm thick may be handled with oxy-acetylene cutting and deliver high quality results.

Light steel structures

The technological equipment of our company allows us to produce various steel structures. We make various lids, racks for pane glass, frames, fence components, steel platforms with railings, etc.

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.

Metal welding

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

Oxy-acetylene cutting

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.

Metal machining

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:

Metallurgical material

Sheet metal

We usually process quality S235 J+AR sheet metal with thicknesses from 2 – 10mm usually in these formats:

Standard Nonstandard
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.

About us

In order to ensure the supply chain and to allow for a continuing quality enhancement, we founded the company AIB KUNSTMANN Metal s.r.o. in the Czech Republic in 2003. Here too, we cherish the principle of the medium-sized, owner-managed company. We ensure the supply with steel containers by an automated tray production in our 2. branch in CZ.

Here again, the customer is our focus: ensuring the supply chain, optimization of prices, quality improvement.
