What Relbo does

Relbo S.r.l. is an Italian designer and manufacturer of die-casting automation equipment, founded in 1989 as a subsidiary of Colosio Presse and headquartered in Rezzato (Lombardy), Italy. The company specializes in three interconnected product families used by die-casting foundries: (1) electric and electromechanical lubricators organized in six series (3G, Speedy, PLUS S, PLUS LS, Directo, PLUS TELE) covering die-casting machines from 90 to 3,000 tons, leveraging servo and brushless motors for high-speed movement (up to 2 m/s vertical, 20 m/s² acceleration); (2) six types of lubrication heads (Standard, Standard con Soffiaggio, A 3 Fasce, RN Modulare, RN Dedicata, Speedy) configured per die geometry; (3) eight nozzle variants (Eco 6, ECO 7, Tipo 5 internal/external mixing, Tipo RNE, RNI, RNC, ECO DOS) for application precision and release-agent savings. These are complemented by extraction and lubrication robots (including its own ARCOFAST 3 electric extractors and integrations with ABB, Kawasaki, Fanuc, Kuka, and Comau 6-axis robots) and accessories (cooling tanks, release-agent distribution units, marking systems). All products are designed and manufactured in-house at its Rezzato facility, which recently added a machining department for complete production control.

Core offering

Relbo designs and manufactures automation equipment for die-casting foundries, including electric and servo-driven mold lubricators (Serie 3G, Speedy, PLUS S, PLUS LS, Directo, PLUS TELE), lubrication heads, precision spray nozzles, extraction robots (ARCOFAST 3 and 6-axis robots), lubrication robots, and accessories such as cooling tanks, release agent distribution units, and marking systems. The company supplies complete automation solutions for cold and hot chamber die-casting machines from 90 to 3000 tons.

Product overview

Relbo is a manufacturer of automation and robotics solutions for die-casting foundries, founded in 1989 by Colosio. The product portfolio centers on three core product families: (1) Lubricators — six series of automatic mold sprayers (Serie 3G, Serie Speedy, Serie PLUS S, Serie PLUS LS, Serie Directo, Serie PLUS TELE) serving machines from 90 to 3000 tons; (2) Lubrication Heads — six types (Standard, Standard con Soffiaggio, A 3 Fasce, RN Modulare, RN Dedicata, Speedy) designed for use across the lubricator lines; and (3) Nozzles — eight types including Eco 6, ECO 7, Tipo 5 (internal/external mixing), Tipo RNE, RNI, RNC, and ECO DOS. These are complemented by Automation products (Robot di Lubrifica and Robot di Estrazione) and Accessories (Vasche di Raffreddamento, Centralina distribuzione distaccante, Marcatrici). All products are designed and manufactured in-house for die-casting plants serving automotive, industrial, and manufacturing sectors worldwide.
