    Winkelmann MSR Technology GmbH + Co. KG is a subsidiary of Winkelmann Group, founded in 1898 by Heinrich Winkelmann and Caspar Pannhoff and still owned by the Winkelmann family. Winkelmann Dynaform Technik GmbH + Co. KG in Ahlen was founded in 2002, only one year after Dynaform GmbH was integrated into Winkelmann Group. Due to the continuous growth, the present production hall was expanded to 10,000 m² at the end of 2007. In the scope of the acquisition of the former Metall Spezial Rohr GmbH (MSR) from Schwerte, Dynaform Technik became the current Winkelmann MSR Technology company. At the same time, the product range of vehicle technology was expanded by industrial applications around aviation and aerospace as well as defence technology.

    • Industrial Applications


      High-precision tubes or rotation-symmetrical components produced by way of flow-forming are used in many different industrial areas. Examples are general engineering and plant constructions, pressure, medical and pump technologies, as well as hydraulics and pneumatics cylinders. On request, we produce smallest amounts of 1 piece or annual volumes of several hundred according to jointly developed component constructions.

      gehause Housings
      Cylindrical, conical or in combination, housings of stainless steel, Inconel, aluminium or other metals can be produced seamlessly from sheet metal or forged parts by way of flow-forming. Frequently, functional areas and flanges are integrated and thus reduce otherwise necessary production processes.
      Cans for vacuum pumps, filter pots, vessels for medical technology and pressure containers of all kinds are just a few examples for this.» more pictures

      rohre High-precision tubes
      High-precision tubes with wall thicknesss of 1-5 mm or extremely thin-walled tubes, also referred to as sleeves, with wall thicknesses in the area of 0.1 -1.0 mm, are used in many different areas of the industry. A great selection of usable materials, such as Inconel, stainless steel, nickel, aluminium, copper, niobium, tantalum, titanium therefore offer best solutions for your application, for example as cylinder tubes for hydraulics and pneumatics cylinders, cooling rollers for the steel industry, pipes for deep drilling technology, rollers for the pressure, textile and film industry, high-precision tubes for magnetic resonance imaging.
      Flow-formed thin-walled sleeves are used, e.g., as belts in motor technology or carrier tubes for carbon-fibre-coiled cylinders and pressure containers.
      Surface qualities up to Ra = 0.1 µm and diameter tolerances in the range of H7 can be reached. In conventional steels/stainless steels, cold hardening permits generation of a tension resilience of up to 1600 N/mm² at concurrently good elongation.» more pictures

    • Aerospace industry



      The aerospace industry recognised the benefits of the flow-forming procedure many years ago and applies it increasingly in many different components. Drive shafts for airplane drives and helicopters, pressure accumulators, hydraulic cylinders for chasses and other applications, as well as control nozzles for satellite motors have been beneficially produced by way of flow-forming – the state of the art for years.

       

      teaser_tr01 Drive shafts for jet engines
      Forming of shafts in the hardened condition to the finished part’s dimensions eliminates the otherwise-present distortion when tempering and drastically reduces the costs for balancing. The high precision of spinning roller technology permits the design of wall thicknesses very close to the theoretic minimum with the result of lowest component weights and imbalances. Tempered steels of all kinds and highly temperature-resilient steels are used for this.» more pictures

      teaser_heli01 Drive shafts for helicopters
      Tail rotor drive shafts made of titanium, stainless steel or aluminium are predestined components for flow-forming procedures. The shafts are up to 4 m long, have a wall thickness of 1 – 3 mm and pose high demands to straightness and concentricity. The precise flow-forming procedure permits producing these shafts with a wall thickness tolerance of less than 0.05 mm and a concentricity of inner- to outer diameter of less than 0.03 mm. Different wall thicknesses within a shaft can be implemented easily in material utilisation of up to 97 %.» more pictures

      teaser_hz01 Hydraulic cylinders
      Cylinders and pistons with an integrated piston rod for landing gears and actuators for doors or other applications are made of stainless steel, such as 15-5 PH. The cold forming process reduces material loss by more than 60% as compared to conventional mechanical processing. Integration of connections and other applications can reduce the number of components at any one cylinder, which saves assembly effort and weight.
      Weight-optimised cylinder pipes and piston rods with integrated pistons that have a component length of up to 2 m can be produced beneficially by the flow-forming procedure.
      End processing into components ready for installation takes place on state-of-the-art turning and milling machines.» more pictures

      teaser_kd01 Cones, nozzles
      Seamless cones, housings and nozzles of niobium, tantalum, titanium, Inconel or other heat-resilient materials are beneficially produced of sheet metal by way of conic flow-forming, referred to as “shear-forming”. Extremely thin wall thicknesses in the area of 0.2-0.5 mm, as well as wall thicknesses of up to 10 mm, can be produced with outstanding surface qualities and highest accuracy in contour and wall thicknesses.» more pictures

    • Defense technology


      Forming of steels in the tempered, highly resilient condition is an essential part of the production of rocket motors and other light-weight construction parts where the additional cold hardening permits the production of very thin-walled, high-strength components. Launch-tubes, warhead sleeves and hollow charge assignments are also applications for flow-forming. The metal-spinning procedure is also used to produce running rollers for track vehicles.

      teaser_mg01 Motor housings
      The production of rocket motor housings by way of flow-forming, based on round material or forged parts, reduces material use by 60 to 80 %. High-strength tempered steels such as SAE 4130 or curing alloys such as Maraging, aluminium and stainless steels (15-5 PH, 17-4 PH) are outstanding for this application.» more pictures

      teaser_rg01 Rocket tips, warhead sleeves
      Conical hollow bodies are produced by shear flow-forming (conical flow-forming). The components are usually made of one seamless sheet. A combination of curved conical shapes (ogives) and straight cones in connection with cylinders permits diverse design of the component geometry. The usable materials are the same as in cylindrical flow-forming procedures.» more pictures

      We produce products and assemblies ready for installation from many different materials. They are used in diverse applications and many different industrial areas. Different chipless cold forming procedures are used in production

    • Flow-forming of clutch carriers

      Flow-forming includes a pre-form (pressed, turned, drawn, forged) being pushed onto a flow-forming mandrel held by the main spindle with low tolerance. The pressure plate fastens the pre-form to the mandrel. The main spindle drive rotates it. The pre-form is moved along by a friction-lock. Flow-forming is applied to the circumference of the pre-form locally. The direct pressure effect of the roller plastically deforms the pre-form material. The defined axial movement of flow-forming leads to the starting wall thickness of the pre-form s0 being reduced to an adjustable final wall thickness of s1, while the starting length L0 of the pre-form extends to the final length L1. The inner contour of the workpiece is formed directly by the spinning roller mandrel (imaging procedure). In this manner, high-quality workpieces with an inner profile can be produced if the mandrels are shaped accordingly.

    • Shear-forming

      A pre-form (flat blank or preformed blank) is fastened on the shear-forming tool with a pressure plate and rotated by the main spindle drive. The pre-form is moved along by a friction lock. The shear-forming rollers are applied locally at the circumference, starting from the bottom to the opening diameter of the pre-form. The direct pressure effect of the rollers plastically deforms the material and produces the workpiece in one shear-forming overrun. Material is reduced under mathematic conditions, the so-called shear-forming law.

      skizze_projizieren
    • Metal-spinning

      Metal-spinning includes fastening a pre-form (flat blank or preformed blank) centrically against the mandrel with the pressure plate and rotated by a friction lock via the main spindle drive. The spinning roller is locally applied to the circumference of the pre-form. The direct pressure effect of the spinning roller gradually applies the material to the tool in an alternating sickle-shaped movement between the bottom and the edge of the round. Then the finished part is put into its final shape by the smoothing overrun.

    • Grob-forming

      The Grob cold forming procedure is based on the principle of breaking up the general forming work to be produced into many individual forming steps. A pre-form (e.g. deep-drawn bowl) is pushed onto an interlocked tool mandrel and fastened with a pressure plate. Two rollers facing the mandrel on either side rotate around one axis each to form the pre-form according to their geometry and that of the tool mandrel by plastically deforming the material by touching the outer-most point of their circle. The mandrel is turning synchronously in time to the rotating rollers so that rotation of the rollers by 360° according to the rotating angle of the mandrel to the component area to be formed subsequently, takes place. At the same time as the rotating movement, the mandrel is evenly axially advanced so that the pre-form is formed in the axial direction via the workpiece height to be produced.

    • Profiling

      fertigung_01

      When profiling, a pre-form (flat blank or deep-drawn bowl) is centrically clamped against a tool held in the main spindle by a pressure plate and rotated. The pre-form is taken along by a friction lock. Profiling takes place in several forming stages, with several forming rollers with different outer profiles in sequence applying the pre-form onto the chuck and generating the desired outer profile of the workpiece. The pressure effect of the outer profiled forming rollers plastically deforms the material.

    • Deep-drawing

      tiefziehen

      Depending on economic aspects, component geometry and subsequent forming procedures, pre-forms may be produced on single- or multiple-staged presses by deep-drawing.
