About Mechtop AG
Mechtop AG is a Swiss industrial manufacturing and service company headquartered in Wangen bei Olten. The company manufactures steel structures such as platforms, railings and stairs, tanks and apparatus including special solutions with agitators, controls or heatable jackets, as well as pipework and pipe distribution systems for pipe and steam line construction. At its own plant, a CNC machine fleet from DMG Mori is available with 5-axis milling machines (DMU 65 with pallet loader), 3-axis vertical milling machines (CMX 1100) and a universal lathe (CLX 450); welding is performed with TIG, MIG, MAG, electrode and orbital welding systems. Materials are carbon steel, stainless steel, chrome steel and plastics. Since 2016, following the acquisition of Wyss Logistik with 30 years of expertise in conveyor technology, and since 2011 Swiss main representative for A-Safe impact protection. Customers come, among others, from the food, paper, pharmaceutical and chemical industries as well as from environmental and nuclear technology; in addition, maintenance, machine overhaul, installation, relocation and engineering services are offered.
