Our Capabilities
Engineering Services to Power Precision Magnetics
GB International offers a comprehensive suite of engineering and manufacturing services that support the entire product lifecycle—from design and prototyping to full-scale production. We specialize in helping OEMs, system designers, and procurement teams accelerate timelines, reduce cost, and improve the reliability of custom inductors, transformers, and assemblies.
Tailored to Your Application
We design and manufacture toroidal, planar, and bobbin-wound magnetic components to meet your exact performance, size, and thermal specifications. Whether you're building for industrial power systems or electric vehicles, our engineering team will support you from early design through scalable production.
Automotive Power Systems
Automotive-Qualified Magnetics for EV and Hybrid Platforms
GBI provides AEC-Q200 qualified transformers and inductors for onboard chargers (OBCs), DC-DC converters, and hybrid powertrains. We support full lifecycle testing, validation, and automotive-grade encapsulation at scale.
Design Engineering
Collaborative Technical Support
Our in-house engineering team works alongside yours to review drawings, recommend optimizations, and refine magnetics for efficiency, manufacturability, and cost. With support from both our U.S. and China facilities, we ensure smooth transitions from prototype to production.
Thermal Encapsulation
Durability in Demanding Environments
Using advanced potting materials and proprietary techniques, we apply thermal encapsulation to improve heat dissipation, protect against environmental damage, and extend product life—ideal for EV, military, and industrial-grade applications.
Failure Mode Analysis
Data-Driven Reliability Engineering
Our team offers root cause analysis for returned or failed components. We analyze stress, heat, vibration, and EMI factors to inform improvements in both design and process.
COst-Reduction Design Review
Optimize for Budget Without Compromise
We identify ways to reduce material cost, improve efficiency, or transition to more scalable designs—without sacrificing quality or performance. Our dual-site model supports both high-mix low-volume and high-volume production.
Prototyping
Accelerate Time to Test
Our U.S. facility specializes in rapid-turn prototypes to help your team test and refine designs faster. We offer short-run production with tight tolerances and fast lead times.
Environmental & Qualification Testing
Built for Compliance and Longevity
We perform validation testing including thermal cycling, vibration, and environmental durability in compliance with automotive, military, and industrial standards.
Custom Manufacturing
Flexible Solutions, Scalable Results
From custom tooling to final assembly, GBI provides vertically integrated manufacturing that supports unique requirements in magnetics, mechanical packaging, and thermal design.
