Welding

Welding of metal sheets, aluminium and stainless steel and grinding to smooth joints and corners. By welding its joints achives maximum visual appearance and water tightness of metal sheets.

Thermal cutting & punching

Thermal cutting of low alloyed, stainless steel and aluminium sheets up to size of 4000 x 2000 mm.

Punching of thin metal sheets low alloyed, stainless steel and aluminium up to size of 6000 mm lenght, thickness up to 3 mm.

Cold forming

Cold forming of metal sheets in all flat shapes using Trumpf made bending machines. Bending of sheets in lenghts up to 4500 mm using force up to 230 metric tons.

Tempering line & hst

Furnace for flat glass thermal toughening or heat strengthening for glass thicknesses 4-19 mm in jumbo sizes.

Incorporated automated line scanner determination of roller wave and edge deformation.

All thermally toughened glass can be additionally subjected to heat soak test, which significantly reduces the spontaneous breakage risk.

ISO & INSULATING glass

All single glass units processed in other KFK's glasswork lines can be assembled in double or multiple insulated glass units, in jumbo sizes and in thickness up to 100 mm, with the possibility of stepped-edge units.

Total production capacity of 200 000 m2 units per year in one shift (based on average unit size of 2,5 m2).

Digital print & laminating

Ceramic ink digital prints standard or custom designed patterns or images in a over pressurized clean-room climatized environment.

Internal quality control acording to EN ISO 12543 standard series and CE marking acording to EN 14449 standard for laminated and laminated safety glass.

Each glass pane is washed automatically before entering the printing/enamelling process.

Powder-coating

• Industrial powder coating – high-quality, durable coating finish, with good corrosion protection and excellent visual appearance
• Horizontal continuous powder coating line with automatized powder applicators
• Capable of powder coating metal sheets and profiles up to 7000 mm in length
• Chromium free certified pretreatment of metallic materials
• Qualicoat and GSB International certified
• Daily quality assurance and testing procedures ensure maximum quality of coating and compliance with all project requirements

MEHANICAL IMPACT TEST

All impact test we can provide in accordance with EN 14019:2004 and Tehnical note number 76 for the UK.

• 1. Heavy soft body impact test

Soft body test may be caried out using the double tyre impactor as described in EN 12600 or a convas spherical/conical bag with a diameter of 400 mm and filled with 3 mm diameter glass sphere to give a mass of 50 kg.

Impact tests are carried out by allowing the impactor to swing in pendulum movement to hit the specimen normal to its face. The height through which the impactor swings is adjusted to give required impact energy.

• 2. Hard body impact test

A steel ball of 50 ± 1 mm or 60 ± 1 will be used

The ball shall be either:

- Dropped from a tower onto a horizontal surface, or

- Suspended as a simple pendulum and allowed to swing against a vertical surface

• 3. Impacts from cradles

Specifiers can require that cradles are designed to limit severity of potential impacts to values given in tables 4 and 5 of Tehnical note No 75.

WWAS

Basic and foremost meaning of our test facility is systematic checking, verification and quality control variety of facade system according to all proscribed regulations and standrads.

We are able to perform various tests such as:

Sound testing

For Sound Testing, we use the Brüel & Kjær Class I measurement system.

Laboratory measurement of the flanking transmission of airborne sound between adjoining rooms and measurement of airborne sound insulation facade elements, doors and windows.

We are able to perform various tests such as:

1. Laboratory measurement of the flanking transmission of airborne sound between adjoining rooms – Test method EN ISO 10848-2

2. Measurement of airborne sound insulation – Test method EN ISO 10140-2 (ASTM E90)
