ASSO

What ASSO does

ASSO is an Italian privately-held designer and manufacturer of hot runner systems and related injection-molding tooling, founded in 1988 and headquartered in Florence. Its core products are precision-engineered injectors (FLX, VFLX, PKX, PKXL, DPMX, DPLX, DPO, O-MAX families), melt distributors, HOT-HALF and FAST shutter sub-assemblies, control units, and micro-molding systems, with design, simulation (Moldflow, thermal FEM), and manufacturing kept in-house. The technology centers on thermal management and gating of thermoplastic melt inside customer molds, with shutter and coaxial nozzle architectures supporting technical applications where gate quality, residence time, or cleanliness are critical.

The company sells engineered, configured systems on a quote-based model with an 8-hour response commitment and typical 10-20 day delivery, served through direct sales and an Italian dealer network. End-markets span packaging, medical, lighting, automotive, cosmetic, micro-mechanics, and vending/cutlery — a deliberately broad vertical mix for a sub-50-employee specialist. The business model is project-anchored, with revenue tied to engineered system sales and aftermarket/consumable replenishment rather than subscription or volume licensing.
