Additive Manufacturing

ELECTRON BEAM MELTING

Selective Electron Beam Melting (SEBM) is a powder-based process for the additive manufacturing of fully dense metal components. Each layer of the powder bed is melted to the geometry defined by a CAD model.

The SEBM-process provides complex-shaped parts without additional equipment and extensive manufacturing steps. SEBM is a competitive manufacturing technique for the  implementation of small batches and individual parts.

A high power electron beam is generated for a high melting capacity. The interaction between metal powder and highly accelerated electrons of the beam results in lattice vibration as well as fusion and vaporizing of the raw material.

Temconex® - Technology

Continuous products of metal powder

The Temconex® process is a new generation of the so-called ConformTM process developed at NMF for using powder, chips or granules as feedstock. Until now, mostly nonferrous metal rods out of aluminum or copper were used as feedstock, which were converted to continuous wires or rods of desired geometries in only one processing step. The usage of powder, chips or granules as feedstock is theoretically possible, but is almost never used in industry.

The continuous powder extrusion machinery is set up at NMF with a highly improved temperature control compared to conventional machines. This modified extrusion press provides the basis for Temconex®-Technology (Temperature controlled Continuous Extrusion). The Technology expands the range of workable material tremendously.

It is also possible to prepare the bulk material before processing in the Temconex® process by means of a roller compactor at NMF. This granulation process enables a binder-free and dry agglomeration of metallic powders or powder mixtures.

Injection Molding of Magnesium Parts (Thixomolding®)

Thixomolding® is a new production process for magnesium parts. Similar to the injection molding technology for plastics, magnesium granules are metered from a feeding hopper into the screw of the thixomolder. Within the screw the magnesium material is heated up to the semi-solid state while it is transported to the nozzle. Due to shearing the solid phase is transformed from a dendritic to a globulitic shape. As a result viscosity is reduced. In addition the melt is shear thinning.

Processing Magnesium in the semi-solid state has several advantages concerning the quality of the parts and the economics compared to conventional die casting. Due to a closed flow front entrapment of gases and oxides is reduced. The mechanical properties are improved and the parts can be heat treated and welded. In addition the reduced solidification shrinkage leads to better tolerances. Lower energy consumption and reduced thermal strain of the mold is reducing the costs.

Up to now Thixomolding is mainly used for producing thin-walled housings in Asia and North America. Most of the parts are produced from AZ91. 

At NMF the first Thixomolding® machine in Europe from Japan Steel Works was set up in March 2002. The machine has a clamping force of 220 t, the maximum shot weight is 660 g Magnesium. For fully automatic operation auxiliary equipment, as for example a take-out robot and spray-robot, was added. 

Several demonstration components of different wall thickness were cast for a wide range of processing parameters. The properties of the components (fraction solid, mechanical properties and porosity) were evaluated. It has been proven that the usage of low processing temperatures (and therefore high solid phase contents) reduces the porosity significantly.

Processing at low temperatures (and therefore high solid phase contents) can reduce the porosity of thick-walled parts significantly.

In the near future a comparison of thixomolded® components with die cast parts will be carried out. Especially the potential of the new technique for automotive components will be investigated. One focus will be on small lot production. Furthermore, the injection molding process will be enhanced at NMF. For example, the development of new magnesium alloys, the production of metall-matrix composites, and the design of hot runner systems will be investigated.

Lightweight Design by Sheet Metal Forming

Within the field of Lightweight Sheet Metal Design support for manufacturing of various parts made out of many different materials can be given. Both, common high and ultra-high strength steels and aluminum-alloys can be supported. Additionally Know-How for forming of titanium and magnesium is existing. Usually the mechanical and forming relevant properties of materials are determined by material characterisation. These are the most important basics for FE-based process and tool design. NMF can support starting from FE-based modelling until manufacturing of small batch series. In this connection the FE-simulation is used for covering the manufacturability of the part and identifying potential for improvement with respect to component and tool. Using FE-simulation expensive and time-consuming experiments can overcome.

The major field of activity are:
-Bulk Metal Forming,
-Characterisation of Components,
-Laser Cutting according to customer,
-Material Characterisation,
-Process and Tool Design and
-Sheet Metal Forming.
