In-House Manufacturing Capabilities
All manufacturing processes are fully in-house — including CNC machining, Swiss turning, sheet metal fabrication, die casting, injection molding, and secondary finishing operations. We do not broker work to third-party vendors or use undisclosed subcontractors. This vertical integration enables stricter quality oversight, more agile production scheduling, and greater accountability on committed delivery timelines.
ISO-Certified Quality System
Our manufacturing facility is certified to AS9100D for aerospace, IATF 16949 for automotive, ISO 13485 for medical devices, as well as ISO 9001 for quality management and ISO 14001 for environmental management. Every production batch moves through a fully documented quality management system with complete traceability — from raw material certificates and incoming inspection all the way through to final inspection reports and shipment records.
Free DFM & Engineering Review
Simply upload your 3D design files, and our experienced engineers will conduct a full design for manufacturing (DFM) review — entirely upfront, before any production commitment or payment. We identify potential manufacturability challenges, suggest optimized tolerance bands and material alternatives, and deliver detailed per-unit cost projections at your target production volumes. This upfront analysis ensures design issues are resolved digitally, avoiding costly rework and delays after tooling has already been produced.
Comprehensive Engineering Support
A single dedicated engineering team manages your entire project from initial design review through final shipment. You have direct, ongoing access to the engineers responsible for your job, with seamless, coordinated handoffs across every stage — machining, surface finishing, quality inspection, and logistics. Instead of juggling multiple suppliers and communication chains, you manage one relationship with one accountable team.
