Competence in Polymers
heba-tec is a manufacturer specialised in polymer engineering, based in Burgthann/Ezelsdorf (district of Nürnberger Land, Bavaria). The company develops and manufactures elastomer elements from tightly specified rubber and polyurethane high-performance compounds as well as sliding elements made of modified thermoplastic materials. The product range comprises rubber hollow springs, rubber-metal buffers, spring washers, compression springs, buffer stops, cellular springs, rubber moulded parts, Vulkollan®/PUR components including extrusion profiles, as well as thermoplastics; customised special solutions are also offered. In addition to development and design, heba-tec carries out re-engineering of components in the aftermarket segment. Materials testing, operated as an in-house test laboratory, is the company's key competence: verification and validation are performed there as part of product development, material characteristics are determined, pre-delivery quality assurance and continuous quality monitoring of production are carried out, along with failure analyses. For complex tasks, the company collaborates with universities and research institutes.

Additional services
Quality and Materials Testing
Materials testing is the company's key competence and is carried out in the in-house test laboratory with calibrated equipment, including Zwick Z250 and Z600, a Roell Amsler dynamic testing machine and a Zeiss Calypso coordinate measuring machine. This is supplemented by qualitative and quantitative investigations for development, pre-delivery QA, process optimisation and failure analysis.
