Medical Device Sub-Assemblies

As medical devices become more complex and miniaturized, OEMs need assembly partners who can deliver consistent, repeatable, and fully traceable sub-assemblies. Helios Precision Tech provides medical-grade sub-assembly services engineered to meet the strict performance, quality, and regulatory expectations of today’s medical device market.

Our focus is simple: quality, consistency, and confidence in every assembly we deliver.

We combine advanced manufacturing technologies with controlled, documented assembly processes to ensure every component fits, functions, and performs exactly as intended.

Key Advantages

• ISO 9001-aligned assembly workflows
• Repeatable, validated processes for consistent performance across production runs
• Tight-tolerance component integration using precision-machined parts from our EDM, Swiss CNC, and VMC platforms
• Controlled environments to protect sensitive components and maintain cleanliness
• Full traceability from raw material through final inspection
• Scalable production from prototype builds to high-volume assemblies

OEM teams gain a partner who understands the critical nature of medical-grade assembly and the importance of reliability at scale.

Our sub-assembly services support a wide range of medical device applications, including:

• Micro-surgical instrument assemblies
• Catheter-based device sub-assemblies
• Sensor housings and micro-enclosures
• Precision tube-and-wire assemblies
• Multi-component mechanical assemblies
• Hybrid assemblies combining machined, welded, and purchased components

We integrate components with extreme care, ensuring alignment, fit, and function meet your engineering intent.

• ISO 9001-aligned quality management system
• Documented assembly procedures and controlled work instructions
• High-magnification inspection and digital microscopy
• Functional testing and dimensional verification
• Lot-level traceability and complete documentation packages
• In-process checks to ensure consistency and reduce variation

Our quality systems give procurement teams confidence that every assembly meets regulatory and performance requirements.

Helios Precision Tech offers a unique advantage: we manufacture many of the components we assemble.

This integration provides:

• Better control over tolerances and fit
• Reduced lead times and fewer supply chain variables
• Seamless communication between machining and assembly teams
• Faster iteration during development
• More consistent outcomes in production

The result is a smoother, more reliable path from concept to finished sub-assembly.

We’re here to support your design, prototyping, and production requirements.
