Contract Manufacturing Capabilities

Specializing in Machining Metals and Parts/Component Manufacturing

5-axis CNC milling and multi-axis turning capabilities handle complex geometries with repeatable precision. We work with aerospace-grade aluminum, titanium, stainless steel, and engineering plastics like Delrin. Perfect for low to medium volume production runs where quality cannot be compromised.

Tight Tolerances: ±0.0002 in (critical) / ±0.0004 in (general)

Our industrial 3D printers deliver production-ready parts, not just prototypes. From concept validation to functional end-use components, we print in engineering-grade resins and high-strength materials. Perfect for rapid iteration, complex geometries, and low-volume manufacturing.
Stereolithography (SLA) for smooth surface finish, Selective Laser Sintering (SLS) for functional parts, FDM with fiber-reinforced materials for strength

GeoMark PRO Class 1 laser marking system provides permanent, high-contrast marks on metals and plastics. Essential for serialization, traceability, and compliance requirements in aerospace and defense manufacturing.
Annealing and heat marks on stainless steel
Deep engraving for permanent identification
Color change marking on plastics
Serialization and barcoding
