About Portec AG
Portec AG is a Swiss specialist in the development, production and distribution of porous materials and moulds. Under the METAPOR® and ESPOR® brands, the company manufactures microporous, air-permeable block materials based on aluminium, stainless steel or ceramic granulate as well as custom porous aluminium moulds. METAPOR® block material can be machined with standard CNC machines, with the pores not clogging unlike sintered materials, and is used among other things for air cushion applications, vacuum clamping plates and thermoforming tools. ESPOR® casting moulds transfer complex structures precisely into porous aluminium moulds; in addition, Portec offers cast microporous moulds without CNC machining. The products have been used for over 30 years in the thermoforming, vacuum-forming, vacuum-clamping, automotive and semiconductor industries as well as in other sectors. The headquarters is located in Switzerland (telephone region Canton Zurich/Schaffhausen).
