What does SI Jacobson Manufacturing do?

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.

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.

How do I choose a manufacturer for custom protective cases for electronics?

Look for a manufacturer with experience in your specific device category, in-house design and prototyping capabilities, material expertise in ESD-safe and impact-resistant materials, and the ability to scale from prototype to production. SI Jacobson has partnered with electronics brands for over 90 years, combining custom sewing, thermoforming, and injection molding to deliver protective solutions engineered for real-world conditions.

What materials are used for custom electronics cases?

Common materials include ballistic nylon, Cordura, EVA foam, thermoformed HDPE and ABS, and injection-molded polycarbonate. The right choice depends on impact protection requirements, ESD sensitivity, weight constraints, and aesthetic goals.

Can you manufacture both soft cases and hard cases for electronics?

Yes. SI Jacobson integrates custom sewn soft goods, thermoformed hard-shell components, and injection-molded elements, often within a single product. This hybrid capability means you work with one manufacturing partner rather than coordinating across multiple vendors.

Do you offer ESD-safe packaging and cases?

Yes. We design and manufacture ESD-safe carrying cases and packaging using conductive and static-dissipative materials that protect sensitive electronic components during storage, transport, and field use.
