What GM Finishing does

GM Finishing Srl is an Italian B2B service provider of surface finishing for non-ferrous alloy components, headquartered in Sarezzo (Brescia province, Lombardy). The company operates a job-shop model delivering five integrated services: vibratory finishing (tumbling) using three vibrators (two 600-liter and one 1,200-liter units) with integrated washing and hot-air drying; shot/sandblasting via five dedicated machines (two cluster, three belt type); manual finishing (trimming, deburring, grinding, assembly); mechanical processing (drilling, milling, threading, turning); and 100% visual quality control. Mechanical processing beyond in-house capacity is fulfilled through a network of ISO 9001:2015-certified external partners operating under GM Finishing's control cards and quality protocols. The company has been ISO 9001:2015 certified by DNV Italia Srl since February 2006 and traces its operating history to 1965.

The customer base is concentrated in Italian manufacturing — primarily non-ferrous die casting, brass stamping, refrigeration, firearms, and general mechanical processing — and includes named enterprise accounts such as ISPA Group, Europress FA, Lomopress, Mecmotive, Nuova Framar, Donati Group, Frigotech, Marocchi, and OMCB. GM Finishing generates revenue through quote-based professional service engagements with no public pricing list, operating geographies are limited to Lombardy, and the company sells exclusively via direct B2B channels (website, phone, email, WhatsApp Business, LinkedIn) with no intermediaries. The company is privately held by the Moretti family, with second-generation owners Sandra Moretti (administration) and Marco Moretti (ownership) leading the business alongside production/quality lead Giacomo Quinzanini. There is no disclosed external investment, no parent company, and no M&A activity in the record.
