About Sound Manufacturing, Inc.
Sound Manufacturing, Inc. was founded in 1984 in Old Saybrook, Connecticut, by Brian Cote and Kenneth Oliver. Now a three‑generation family business, the company has been led since 2006 by President and CEO Kelli‑Marie Vallieres, PhD (through 2020) and, since 2020, by President/COO John Vallieres. From its start as a local sheet metal fabrication partner, it has grown into a contract manufacturer serving clients across New England and beyond. The shop provides precision sheet metal fabrication including laser cutting (Trumpf CO₂ and fiber lasers up to 5 kW), CNC punching (Trumpf TruMatic 3000 and TruPunch 5000), forming and bending on Trumpf press brakes up to 10 ft, TIG/MIG/spot welding, deburring and finishing (Lissmac, Timesaver, tumbling), PEM and rivet hardware installation, CNC milling and turning (DN Solutions, Haas), inspection, and assembly/packing. With 40‑plus team members, the facility runs 24/7, holds ±0.005 in dimensional tolerance, processes material up to 1 in thick, and handles short‑run to full‑production volumes, having produced over 10 million parts to date. Customers span telecommunications (server racks, patch panels, enclosures), green energy (bus bars, breaker panels, EV‑charging components, power‑storage housings), defense, automation (robotic bases, control boxes, sensor brackets), packaging (tape‑machine and packaging‑machine components), outdoor power equipment (OEM frames, impellers, leaf boxes for Monster Power Equipment), industrial machinery (welded frames, guarding), data‑center infrastructure, and electrical distribution. The client base ranges from startups to Tier 1 manufacturers; long‑term partners include Intertape Polymer Group and robotics firm Cavalla. The company emphasizes a quality‑as‑culture approach backed by ISO 9001:2015 certification and a reported 99 %‑plus on‑time delivery rate. It cites decades of craftsmanship, continuous investment in advanced Trumpf and CNC equipment, and a commitment to environmental responsibility—including a 30 % CO₂ reduction target for Scope 1 & 2 by 2030—as key differentiators.
