Custom Design & Development
From initial concept through production-ready engineering, we co-develop custom solutions across sewn soft goods, thermoformed parts, injection-molded plastics, metal fabrication, and integrated sub-assemblies. Every capability under one roof, guided by one team.
Domestic & International Manufacturing
SI Jacobson Manufacturing understands that every supply chain is unique. The right manufacturing path depends on your priorities — speed, cost, compliance, or all three. We partner with you to determine the best approach, whether that’s production at our Illinois facility, through our managed international network, or a strategic combination of both.
Warehousing & Fulfillment
When you need more than manufacturing, we extend the partnership into storage, kitting, inventory management, and direct fulfillment. One manufacturing partner managing the full journey from production through delivery.
