Eastek International Corporation Engineers Quality and Partnership into Every Product

Eastek International Corporation stands as a trusted contract manufacturing partner delivering end-to-end solutions across the electronics value chain. Headquartered near Chicago, the company combines American engineering expertise with global production capabilities, helping original equipment manufacturers (OEMs) bring complex, high-quality products to market efficiently and reliably.

With nearly four decades of manufacturing experience, Eastek has built its reputation on vertical integration, bridging product design, precision molding, printed circuit board assembly (PCBA), and final box-build integration. Today, the company operates facilities in the United States, Mexico, and Malaysia, offering customers flexible, scalable, and geographically diverse production options.

“Eastek’s vertical approach lets us solve the hardest problems for OEMs: turning an early prototype into a manufacturable, cost-effective product while protecting quality and supply chain continuity,” says Steve Busch, Vice President of Business Development. “We’ve invested in additional capabilities such as custom battery solutions, injection plastic molding and tooling, and end-of-line testing so customers don’t have to stitch together multiple suppliers to meet program goals.”

A Foundation of Vertical Integration

Eastek was founded on a simple but powerful philosophy: to be a full-service partner capable of supporting customers from concept through production. This vertically integrated model allows OEMs to consolidate design, engineering, manufacturing, and testing under one roof—streamlining communication, reducing risk, and improving product consistency.

The company’s core capabilities include:

• Design and Engineering Services: Eastek provides Design for Excellence (DFX) and multidisciplinary engineering support that helps customers refine products for manufacturability, reliability, and cost efficiency. By engaging early in the design phase, Eastek’s engineers can identify improvements that shorten time-to-market and enhance long-term performance.

• PCB Assembly (PCBA): With high-speed SMT lines, automated optical inspection (AOI), in-circuit and functional testing, and conformal coating capabilities, Eastek delivers both high-mix/low-volume and high-volume production. Advanced traceability systems and real-time monitoring ensure that every assembly meets rigorous standards.

• Injection Molding and Tooling: Eastek’s plastics division designs and produces custom molds and injection-molded components, with secondary operations such as ultrasonic welding, insert and over-molding, and pad printing. By integrating mechanical and electronic assembly in the same supply chain, customers benefit from reduced lead times and improved fit-and-finish.

• Box-Build Assembly: Beyond subassemblies, Eastek provides full product integration—housing assembly, cable management, labeling, packaging, and logistics. This allows customers to receive fully tested, market-ready products.

• Battery and Power Solutions: Responding to the growing demand for electrification, Eastek’s facilities also support battery pack assembly and battery management system (BMS) integration for a range of industrial and transportation applications.

Together, these services form a complete manufacturing ecosystem, one that allows customers to scale seamlessly from prototype to mass production without sacrificing control or quality.

Serving Diverse, Demanding Industries

Eastek’s expertise extends across industries that demand precision, reliability, and regulatory compliance. The company serves customers in:

• Medical and Healthcare – including diagnostic and monitoring equipment where ISO 13485 certification and traceability are critical.

• Industrial and Automation – such as control systems, sensors, and process instrumentation requiring robust performance under harsh conditions.

• Energy and Transportation – encompassing power electronics, battery systems, and components supporting electrified mobility and renewable energy storage.

By applying cross-industry best practices, Eastek delivers tailored solutions that meet both functional and compliance requirements. The company’s multidisciplinary approach enables it to apply learnings from medical-grade manufacturing to ruggedized industrial or transportation applications—an advantage that few competitors can match.

Quality Without Compromise

Quality is more than a checklist at Eastek, it’s a mindset embedded in every process. Each global facility operates under a unified quality management system with ISO 9001 certification, while our Mexico sites maintain additional certifications such as ISO 13485 for medical devices and IATF 16949 for automotive manufacturing.

“Our customers trust us with products that impact lives, including medical instruments, energy systems, industrial controls,” notes Busch. “We take that responsibility seriously. Every process, from component sourcing to final test, is designed to minimize risk and maximize reliability.”

Advanced traceability systems, in-house testing, and continuous process improvement ensure consistent quality across all manufacturing sites. Eastek also maintains robust engineering change control and obsolescence management programs to protect product lifecycles over years of production.

Global Reach, Local Partnership

Eastek’s strategic manufacturing footprint supports customers seeking geographic flexibility and risk diversification. Its U.S. engineering and program management base works in concert with manufacturing operations in Malaysia and Mexico—allowing customers to choose the location best suited to their cost, volume, and logistics requirements.

The company’s Mexico facilities are a centerpiece of its near-shoring strategy, offering North American OEMs a convenient, certified manufacturing option that reduces transit time and tariff exposure. The Malaysia facility extends Eastek’s reach into the Asia-Pacific region, providing a bridge for global customers and suppliers.

“Near-shoring is one piece of our risk-mitigation strategy,” Busch explains. “By operating in Mexico and Malaysia alongside our U.S. engineering base, we help customers balance cost, lead time, and geopolitical exposure without sacrificing regulatory readiness.”

This tri-regional approach ensures supply continuity and scalability, essential advantages in an era of unpredictable logistics and evolving trade dynamics.

Building Value Through Collaboration

Eastek’s customer relationships are built on transparency and partnership. From the initial design review to long-term production management, the company’s teams collaborate closely with clients to define technical requirements, cost targets, and performance expectations.

The company’s quoting and program management process is designed to be transparent, allowing customers to understand cost drivers and design impacts early. Once production begins, dedicated account managers and on-site engineers provide real-time communication and responsiveness, qualities often cited by customers as key differentiators.

“We strive to be more than a supplier,” Busch emphasizes. “Our goal is to be a true partner that helps customers achieve faster launches, higher quality, and lower total cost of ownership. When we succeed together, that’s when the partnership is strongest.”

Looking Ahead

As global manufacturing continues to evolve, Eastek International Corporation remains focused on investing in technologies and locations that strengthen its customers’ competitiveness. Its emphasis on vertical integration, quality systems, and diversified geography positions it to meet the increasing complexity of modern electronics manufacturing, particularly in sectors like medical devices, energy storage, and connected industrial systems.

By maintaining its balance of global capability and personal partnership, Eastek is poised to continue its mission: delivering innovative, reliable, and high-quality products that reflect the strength of true collaboration.
