Powderization

GfE has many various disintegrators and grinding machines for the manufacture of the particle size distribution specified by our customers. The crushing machines are selected according to the particle size distribution to be achieved. Jaw crushers, rotary crushers, roller crushers, roll mills, pinned disc mills, oszillating rod mills, etc. are used. Subsequently, the material is classified by sieving according to customer specifications.
 
For the production of very fine powder, GfE uses rod mills (Cryopalla mills), which can be operated at very low temperatures due to their specific design. This allows for grinding of problematic materials such as titanium and chromium powder, which GfE produces by the ton.

Inspection

In conjunction with regulations, several quality assurance and inspection steps are carried out for products that are supplied for the use in sensitive applications, e.g. in the aerospace industry. We guarantee that our products are free of high-melting and/or high-density particles (e.g., tungsten, tantalum, niobium, oxides, nitrides).
 
In order to ensure this quality standard, GfE maintains two three-stage inspection lines. In the first stage, the products that have been crushed to their final particle size are inspected visually. In the second, fully automated stage, the flow of material is checked under ultraviolet light for any remaining oxide layers. During the third, also fully automated stage, the flow of material is finally subjected to an X-ray check to select high-density particles.

Mechanical Processing

Our mechanical processing capabilities are specially designed to process non-ductile or any other problematic materials. Presently, GfE has several automatic vertical band saws and automatic horizontal band saws at its disposal. Our mechanical processing shop with CNC technology (lathes, mills) expands our capabilities.
