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
(Automated high-bay warehouse)
The following material can be cut: steel up to 25.0 mm, stainless steel up to 20.0 mm (oxide-free), aluminum up to 12.0 mm material thickness.
The max. Machining size is 3000 mm x 1500 mm. All three stocking systems are connected to an automatic high bay warehouse with 220 storage bins (3 tonnes storage capacity). We are thus able to cut during the night shift without staff.

Water jet cutting
5-axis machining of steel up to approx80 mm, stainless steel up to 80 mm, aluminum up to 100 mm - other materials such foam, plexiglass, plastics, glass, stone, sealing material, composite materials, wood, etc. possible.
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...).

As part of the Kurre Group of Companies, we employ over 230 people who understand their craft. We deliver the perfect result — whether individual parts such as prototypes or unique pieces or series productions in variable runs. It is our aim to always be able to offer you, our customers, the latest possibilities of what is possible. That is why we are constantly investing in new technologies and expanding our machinery. In addition, we are constantly developing ourselves and our employees. In this way, we guarantee you solutions that are both efficient and innovative.

In addition to contract manufacturing, we can also offer the complete package with our own design office. Your ideas are in good hands with us and, after detailed advice and planning, will be implemented precisely and precisely. In addition to clean production, we are also happy to ensure professional order picking including labeling — standard service for the generalist.

Thanks to our Fast Lane system in collaboration with an experienced team, we can often offer your wishes even with shorter delivery times.

Welcome to laser product

LaserProdukt GmbH in Alfeld (Leine) is one of the application pioneers of flexible beam processing methods and has gained a wealth of experience in this field since 1984.
Our competencies go far beyond material processing with laser and water jets. As specialists in assembly production, we offer all services that make your work easier for our customers: We support you in the construction of individual components and complete assemblies. We create NC programs, keep an extensive range of materials, design and manufacture processing and testing devices. We take over the complete processing, assemble, carry out sample and functional tests and deliver with in-house vehicles.

Flexible production and the use of modern production technologies enable us to meet the high quality standards of our customers, to realize short delivery times and to offer cost-effective services.

Laser product: Our technology - your advantage

The life coaching Chemnitz eV was founded on 23.06.1990. It currently has 240 members and supervised in the various facilities about 450 people with intellectual disabilities. The workshops are facilities for the participation of disabled persons in working life. They integrate people who do not, can not, or not yet again be working in the open labor market because of the nature and severity of the disability. In the workshops, a training area is available.

Our range of services:

Electric field: Production and assembly of electronic components, assembly of components and devices, disassembly of assemblies and electronic components, inspection and testing activities to customer and preparation of components

Equip the production of individual components of different modules, complex assembly (brake and fan modules), quality control, packaging and heatsink with components: Installation

Packaging and assembly: Compilation of clothing bags and packaging, production of cardboard and overpacks and control

Preparation of components: bending (grid, expand or-Narrow), beads (simple or twisted), Shortening, apply fabric hose, apply heat shrink tubing and shrink, Ausgurten of axial or radial taped components, Manufacture of wire bridges
