About HEMA-CT
HEMA-CT Q-Technologie und Messtechnik GmbH is an independent service center for quality assurance based in Uhingen. The company provides technical services using dimensional measurement and analysis technology: industrial computed tomography, 2D X-ray inspection, 3D scanning with structured light, photogrammetry as well as optical and tactile 3D coordinate metrology (multisensor technology). In the field of non-destructive analysis, pore and shrinkage cavity analyses, inclusion analyses, defect, wall-thickness and structure inspections as well as assembly and joining technology inspections are offered. In engineering, services include reverse engineering, tool correction for injection-molding and die-casting molds, CAD service and contract programming (WinWerth, Calypso). Measurement is performed from a quantity of 1 up to large-scale series, from small parts to large objects, for industries such as plastic parts, mold making, foundry technology, electronics and mechanical engineering. Work is performed in conformity with DIN EN ISO/IEC 17025:2018; the company is certified to DIN EN ISO 9001:2015.
