MG Spa

What MG Spa does

MG S.p.A., founded in 1954 and headquartered in Travagliato (Brescia), Italy, is a metrology specialist that designs and manufactures dimensional measurement instruments, gauges, leak testing systems, and statistical process control (SPC) software for industrial quality control. The company is a wholly-owned subsidiary of Marposs Group, having been acquired in June 2000, and operates under the MG Gauges brand. Its product portfolio spans fixed go/no-go gauges (smooth, threaded, splined), variable gauges with proprietary LVDT/HBT inductive sensors, mechanical, electronic, and wireless bore gauges (M1 Star MBG, M1 Star EBG, M1 WAVE), pneumatic gauges (M1 Air), and a WinGauge SPC software suite (WinGS/pro, Gauge Analyser, SPC-3, MG-Supervisor, CSA, MG-Design). The firm also produces automatic testing machines for dimensional control, functional testing, and leak testing — including helium leak testing technology acquired from French firm TRACE — as well as specialized systems for electric motor commutator inspection and automotive glass profile control.

The company's customer base spans horizontal industrial manufacturing verticals, with automotive and sub-supply identified as the primary sector, alongside aerospace, hydraulic and pneumatic components, electrical components, the glass industry, and machine tools. MG operates as a single-member Italian joint-stock company (S.p.A. a socio unico) and generates revenue primarily through hardware sales (standard gauges and custom automatic machines), one-time software licenses for the WinGauge suite, and accredited calibration and metrology services — MG holds ISO 9001 certification since 1993, ACCREDIA LAT N°133 calibration center accreditation since 1991, and UNI CEI EN ISO/IEC 17025:2005 metrology laboratory accreditation since 2001. Pricing is quote-based and inquiries are handled via dedicated request-for-quote forms on the company website.

Distribution is anchored through the Marposs Group's global sales and service network, which has presence in all industrialized countries and provides worldwide sales structures and post-sale technical support. MG also operates wholly-owned regional market entities in Brazil (MG-EXIM TECNICA LTDA, São Bernardo do Campo) and China (MARPOSS (NANJING) AUTOMATION CO., LTD, Nanjing) to support local distribution. The go-to-market motion is enterprise field sales targeting manufacturing companies, supplemented by direct website inquiries and industry trade show participation, with quote-based pricing and long sales cycles driven by technical specification requirements in regulated manufacturing quality control environments.
