SI Jacobson is a design-led custom manufacturer specializing in carrying cases, protective packaging, soft goods, thermoformed components, and injection-molded products. We partner with brands across medical, defense, automotive, electronics, industrial, and consumer markets to bring products from concept to production.

How long has SI Jacobson been in business?

SI Jacobson was founded in 1934 and has over 90 years of continuous manufacturing experience. We operate a full-scale production facility in Lake Forest, Illinois, complemented by a managed international manufacturing network across Asia.

What industries does SI Jacobson serve?

We serve six primary industries: electronics and technology, industrial tools and equipment, automotive and mobility, military and defense, medical and healthcare, and consumer and outdoor products. Each industry vertical has a dedicated team with specialized expertise.

Where is SI Jacobson located?

Our headquarters and primary manufacturing facility are located at 13950 W Business Center Dr, Lake Forest, Illinois 60045. We also manage international production through trusted partners in China, Cambodia, Vietnam, and Indonesia.

Should I manufacture domestically or internationally?

The right choice depends on your priorities: speed to market, cost targets, compliance requirements, and risk tolerance. SI Jacobson helps clients evaluate these tradeoffs. Our domestic facility supports fast prototyping and compliance-sensitive programs. Our international network supports cost-effective volume production.

How does SI Jacobson manage international manufacturing quality?

Our international partners operate under the same quality standards we apply domestically. We maintain long-term relationships built over decades, provide on-site quality oversight, and manage the full production process so you get global scale without the complexity.

Can you transition a product from domestic to international production?

Yes. A common approach is to prototype and validate domestically at our Illinois facility, then transition to international production for volume. We manage the entire transition ensuring specifications, quality standards, and timelines are maintained.

Domestic & International Manufacturing: Strategic Flexibility, Thoughtful Execution

Built on Legacy. Driven by Partnership.

Every project comes with its own set of priorities—cost, speed, risk tolerance, supply chain complexity. We don't assume we know which matters most to you. We ask.

Our global manufacturing footprint is strategically complemented by a full-scale domestic operation, allowing us to align our capabilities to meet your needs. This isn't about offering options for the sake of options. It's about understanding your operational realities and aligning our capabilities to meet them.

Global Partner Network: Diversified, Resilient, Intentionally Managed

We work with trusted manufacturing partners across China, Cambodia, Vietnam, and Indonesia—relationships built over decades, not transactions. This diversified footprint allows us to reduce single-country exposure, access specialized regional capabilities, maintain competitive pricing, scale efficiently for high-volume demands, and align production with your broader supply chain strategy.

Our international network operates under the same quality standards and partnership principles we apply domestically. You get global scale without the complexity of managing it yourself.

U.S. Manufacturing: Proximity, Agility, Collaboration

When speed, iteration, or closer oversight matter most, our Illinois facility provides a direct line from conversation to production.

Domestic manufacturing allows us to shorten lead times dramatically, reduce your inventory exposure through flexible scheduling, adapt quickly to design changes, and collaborate in real time with our engineering and production teams. For projects where responsiveness is as important as cost, this path often makes the most sense.

The Right Path for the Right Project

We don't advocate for one approach over another. We listen to your priorities—timeline, budget, risk profile, compliance requirements—and help you determine which manufacturing path fits best. Sometimes that's international. Sometimes it's domestic. Often, it's a thoughtful combination of both.

This is what strategic partnership looks like in practice: not just fulfilling orders, but helping you make better decisions about how and where your products come to life.
