  • Industrial sheet metal processing

    At NEUMAIER sheet metal processing we manufacture high-quality sheet metal constructions, welded assemblies and mounting units – both in single piece production and in series. State-of-the-art production methods and machines as well as efficient coordinated operating procedures in connection with our long-standing and highly trained specialist staff enable us to provide high-quality sheet metal processing. A lean manufacturing structure and an extensive sheet metal storage area are the basis for flexible and fast sheet metal processing.

      • Laser cutting: CO2- and solid laser

      • We cut sheet metal with great precision and best quality using high-performance laser cutting machines made by Trumpf. A total of three laser cutting machines are available for this at our company: Two CO2 laser cutting machines with a laser capacity of 6 kW and a solid laser machine TruLaser 5040 fiber with a powerful 5 kW fibre laser.

        The Trumpf laser cutting machines are particularly characterized by a high cutting quality in all sheet thicknesses. High cutting speeds can also be achieved with minimum non-productive times. High process safety is guaranteed in fully automatic operation. We can manufacture both single-item parts and serial parts with our laser cutting machines economically and with perfect quality.

        3 x Trumpf laser cutting machines

        5 kW solid laser and 6 kW CO2-laser 

        Working area:
        max. 6,000 mm x 2,000 mm

        Materials and sheet thicknesses:
        Steel plate: up to 30 mm.
        Stainless steel, wear-resistant steel, aluminium: up to 25 mm.
        Copper and brass: up to 10 mm.
        (other materials and sheet thicknesses on request)

      • Surface finishing: Clean surfaces

      • Various procedures and machines are available for the finishing of sheet metal surfaces at our company, guaranteeing a smooth and clean surface of the cut parts.

        With a Weber multi function machine we can not only deburr, but also chamfer and descale the cut edges resp. polish the surfaces.

        A sandblasting unit with airless blasting-continuous blasting procedure supplements our service capacity in the field of surface reworking.

        Surface finishing performance data

        • Machine: 1 x Weber Grinder
        • Procedure: Grinding, deburring, chamfering, descaling
        • Working area: 6,000 mm x 1,500 mm
        • Material thickness: 1 mm to 100 mm
        • Machine: 1 x Sandblasting unit
        • Procedure: Airless blasting-Continuous blasting
        • Working area: 1,500 mm x 15,000 mm
        • Material thickness: 1 mm to 650 mm

        The advantages of a good processing of the surfaces lies in a lower risk of injury during subsequent handling or further processing. A clean finishing of surfaces is especially important among other things in the case of cut parts that are varnished afterwards. By chamfering the edges for example, a corresponding structure of thicknesses of layers is possible, offering nearly the same service life as the varnish on the surface. If the cutting areas were descaled in addition, the perfect mechanical adhesion is also guaranteed there.

      • Edge bending: CNC bending with 4 press brake machines

      • Customer requirements in the field of bending can be perfectly implemented in our edge bending department with a total of 4 highly modern CNC Bystronic press brake machine. We can produce your sheet metal bending parts with a maximum pressing force of 800 tons and a bending length of max. 6,200 mm. All 4 bending units obtain a first class bending result and are equipped with maximum technical possibilities.

        The Bystronic press brake machines are all equipped with the same control system and the same tools. This enables us to maintain an optimum machine performance and therefore flexible and rapid production of customer orders, both in the case of single-item components and series production. Our press brake machines are controlled by CNC-control system. This enables us to also simulate the planned bending process. Test bends are therefore not necessary. The first part is also a good part.

        Bending performance data

        • Machines: 4 x Bystronic press prake machine 
        • Pressing force: up to max. 800 tons 
        • Bending length: up to max. 6,200 mm
        • Assembly height: up to max. 1,150 mm 
        • Sheet thickness: up to max. 25 mm
        • Lifting height: up to max. 865 mm

        The bending sheet metal is an important procedure in industrial sheet metal processing. For the sheet metal can only be formed into the desired shape using the bending procedure. To do so the sheet metal is pressed into the lower tool (die) by the upper tool (stamp). Many tool variations and dies are available for the various requirements on angle and radii. The sheet metal to be bent is placed on a stop, so that the bending process is carried out as efficiently as possible. The result is a perfect bend and optimum basis for the further processing of the sheet metal product.

      • Laser welding: Reduced costs & highest precision

      • We offer our customers a new and high-performance welding technology with the TRUMPF TruLaser Robot 5020 that has considerable advantages over conventional welding procedures – in both quality and economic respects.

        The energy is introduced without contact and positioned very precisely on the component by the laser beam. Because of this only low thermal stress and an extremely limited heat affected zone result. Lean seam geometries and a smooth surface are the result. As a result, reworking is also reduced or even completely omitted. High process speeds ensure short processing times. In addition, the automatic rotation changer makes a simultaneous loading and unloading of the machine possible during the welding process. 

        Laser welding performance data

        • Machine: TruLaser Robot 5020
        • Working area: 2,000 mm x 950 mm x 1,000 mm (larger dimensions on request)
        • Load: approx. 750 kg
        • Laser power: 6 kW
        • Sheets: Sheet steel, stainless steel, aluminium, copper and brass
        • Loading/Unloading: Rotation changer for simultaneous loading and unloading

        Advantages of laser welding

        • Welding of complicated seam geometries
        • Pinpoint, precise energy introduction of low distortion welding
        • Minimum thermal material impact
        • No or only light reworking
        • High automation and welding speed
        • Quality monitoring and documentation of process data
        • High process safety due to fully automatic CNC-control
        • Thermal conduction welding for optically perfect welding seams
        • Deep welding for highest stability

        The TRUMPF laser welding machine is the optimum addition to our previous welding machines. A welding robot made by Cloos is also in use as well as manual welding stations. In this way we can react flexibly and rapidly to the requirements and needs of our customers.

      • Cloos welding robot: Automated welding

      • The CNC-controlled Cloos robot welding machine offers maximum flexibility in automated welding. Thanks to two rotating/swivel work-piece positioners arranged side by side, the machine can be loaded and unloaded simultaneously. By uniting the two work-piece positioners, structural components with a length of up to 7 m can be welded.

        A high seam volume can be generated by using a tandem welding torch. A high welding speed is also possible by using the tandem welding torch.

        An on-line follow-up of the welding seam is possible with a laser sensor attached to the welding torch. This guarantees a clean torch guidance at the work-piece and so ensures high seam quality. Furthermore, the welding torch can be positioned very precisely on the work-piece by the laser sensor.

        • Economical welding also of big components
        • High quality of welding seams
      • Spot welding: joining with utmost precision

      • In the field of spot welding we have two DALEX machines in operation at our facilities: a spot welding machine of type PMS and a spot welding gun of the 3328-6 series.

        During resistance spot welding, or also called spot welding, the parts to be joined are pressed together using two electrodes positioned opposite each other. An electric current is introduced into the parts to be joined by the electrodes. Based on the heat resulting from this (Joule effect) and the force with which the parts are pressed together by the electrodes, a permanent welded joint is produced. With the spot welding machine PMS 12-6 we can also join welding nuts from M3 to M12 using resistance projection welding.
