Make fibers, bubbles, and density visible through X-ray radiation

Qualify lightweight construction through computed tomography

Plastics are predestined materials for lightweight construction applications. To optimally utilize the lightweight effect of the material, their potentials must be purposefully harnessed.

The mechanical properties are direction-dependent. Foremost among these is fiber orientation. In thermoplastic fo…

STZ EURO: Future-proof resource conservation based on VDI 2083-19

Visions for climate-friendly cleanroom operation

For many cleanroom applications, a defined airtightness is not required, especially if compliance with product protection or environmental protection does not demand it. Nevertheless, it can make sense to achieve a airtightness as defined by VDI 2083 Sheet 19 in order to specifically and economicall…
