Our manufacturing services
CNC Machining
Precision milling and turning of metal and plastic parts, 3-axis to 5-axis, from prototype to production.
CNC Aluminum Machining
Lightweight, corrosion-resistant aluminum parts in 6061, 7075, 5052 and more, with anodizing and finishing.
3D Printing
SLA, SLS, MJF, FDM, and metal 3D printing for complex geometries and fast concept models.
Urethane Vacuum Casting
Low-volume plastic parts cast from silicone molds — production-like quality without hard tooling.
Vacuum Forming
Custom thermoforming of PETG, HIPS, ABS, PC and HDPE — large thin-walled parts with low tooling cost.
Sheet Metal Fabrication
Laser cutting, bending, stamping, welding and finishing of steel, stainless and aluminum parts.
Die Casting
Aluminum, zinc and magnesium high-pressure die casting for strong net-shape metal parts at volume.
Rapid Tooling
Aluminum injection molds and bridge tooling for fast, affordable low-to-mid volume production.
Surface Finishing
Anodizing, bead blasting, powder coating, electroplating, polishing, and passivation.
Clear Optical Prototypes
Transparent PMMA and PC parts machined and polished to optical clarity.
