Our company has been established in 1991 (as KUMRU Automotive) and rebranded as KMR Automotive in 2016 in terms of vision and member of boards.

We are mainly producing tubes and hoses for automotive aftermarket by tube bending, hose cutting, brazing, crimping for most of the brands and we are exporting about 70% of our total products to European and US countries. In addition, we are importing our raw materials such as pipes made of first grade of steel from Benteler Germany and hoses are from SEL (Eaton).

The Knupfer Metal Processing GmbH is a sheet-processing supplier for the machinery and special machinery for air conditioning, ventilation and suction technology, clean room technology and the automotive industry and has worked for over 50 years.

We manufacture sheet metal parts, machine covers, protective covers, enclosures, machine bases, machine body and complete assemblies from lot size 1 steel, stainless steel and aluminum.

Our high-tech production in-house include:

Laser Cutting

The max. Machining size is 3600 mm x 2000 mm

Bending
Pressing force of the CNC press brakes: 1 x 320t, 200t x 1, 1 x 36t
ACB angle sensor available, 3-point bending is included as standard, Folding Machine in use

Nibbling and punching
Steel up to 6.0 mm, stainless steel up to 4.0 mm, aluminum up to 6.0 mm
The installation of ventilation gills, beading, perforated grids, rows etc. is easily possible

Welding
(Manually or with robots)
MIG / MAG and TIG, spot and stud welding (threaded bolts and sleeves), welding robot with rotating and tilting table for components up to 5000kg unit weight.

These saws, laps, mech. Machining (milling, turning, drilling, threading), production of flange rings according to DIN 24154 and angle rings to DIN 24155, as well as special rings and segments and paint the assembly and completion according to the surface treatment (powder coating, galvanizing...).

The Kolb, washer and Diekhaus GbR is a sheet metal manufacturing and manufacturing company based in West Saxony.
The development and production of stainless steel mailboxes attention in recent years as far as possible in Vodergrund.
Since October 2014, the contract manufacturing has been built in the areas of lasers, flashings and mechanical processing in the branch office Grimsby.
We are now in a position the entire process chain of sheet metal processing to offer to powder coating of large parts.

We look forward to a mutual cooperation

Demolition equipments, demolition attachments

Demolition and Sorting Grabs
The new generation of demolition and sorting Grabs HCG was created for compact excavators. HC grabs can be very effective for: Demolition projects, Sorting from scrap and waste, Handling. Thereby a significant reduction of the wast disposal costs is achieved.

Pulverizer, fix and rotating
The new generation of pulverisers, HCP and HCP-R have been developed for the primary and the secundary demolition. The HC-Pulverisers can be very effective, and can be used with absolute safety for demolition of constructions, brickwork, concrete plates, concrete structures and recycling activities

Concrete Crushers
Our Multiprocessors, new generation of Concrete Crushers, have been designed and developed for universal use in heavy demolition and recycling works. These are designated for 15 to 45 tons excavators. The Concrete cruschers can work very effective and trouble-free in primary and secondary demolition.

KOVAC Stahl was founded in 1967 in Graz and has developed into a modern steel processing company at three locations (Brunn am Gebirge, Zagreb/CRO and Tomislavgrad/BIH) with around 65 employees.

Laser cutting, edging or bending, welding, coating are our core competencies in steel processing.
KOVAC Stahl sees itself as a source of ideas and manufacturing partner for your company and is happy to help you implement your ideas and projects. Our services and expertise cover a wide spectrum — from consulting for the development of new products to the production of prototypes and series production, but also as a parts supplier or supplier of entire assemblies or sheet metal components for your own production.

Kovinc d. o. o. is a family manufacture and service company. The beginning of the company dates back to 1989, when Pavel Žvelc started producing wrought Kropa lamps and ironmongery work. The volume of production started to grow and the production programme was gradually supplemented. In 1990 we built a new hall and bought new machinery. We targeted our production towards manufacture of various metal products for the needs of builders’ joinery and light metal constructions. In 2001 the founder’ son, Damjan Žvelc took over the company. At first, he operated a Sole Trader business, but in 2005 a limited liability company Kovinc d. o. o. was established.

We are noticing a growth in operation of the company. Currently we sell the majority of products and services in the domestic market. We also started increasing sales in the foreign markets.

We are specialised for three basic production programmes:

metal interior equipment programme
light metal constructions programme
programme of products for complete graphic image of buildings

We also offer a wide range of services for modification the sheet metal and profiles on the state-of-the-art CMC machines. We constantly follow the technological progress and upgrade our production. We offer products and services, such as constructing, advising and on site installation to our customers. We obtained an international certificate for welding according to ISO 3834 standard. We have all the necessary agreements and certificates for our products. Especially, we want to point put the SIQ certificates for our advertising boards

Since 1992 our company has been dealing with the cold bending of hollow sections. All started in the first half of the ‘90s when we intended to produce bent-metal furniture. After having mastered the bending technology of ordinary tubes made of constructional materials, we proceeded to a more demanding technology of the bending of thin-walled tubes having the bending radii under 2D of the tube diameter. Using special tools, such as ball mandrels and smoothing devices, we are able to achieve high quality of a bending both from the visual point of view and in maintaining a minimum tube diameter deformation. We obtain similar results not only with materials made of construction steel, but also with materials made of anti-corrosive steels and aluminium alloys. We also get good results with the bending of square and rectangular sections.
The main part of our production program consists in products manufactured in cooperation. These are components of shop equipment, protective frames of cross-country cars, series of various bent holders, frames, reinforcements of agricultural machines and injection piping. Other supplementary technologies are grinding of tubes under chrome, tube and section twisting, horizontal forging, MIG and TIG welding.
At present we have been looking for partners to be able to use the full capacity of our bending machines.
