We cut steel up to 20 mm and aluminum up to 12 mm with positional accuracy of ±0.02 mm. Our 30 fiber laser machines handle flat sheet profiling, fine-feature cutting, and high-volume nesting. Parts come off the table burr-free and ready for the next operation without secondary cleanup.

01
Precision and Quality
Zeiss CMMs and optical measurement
systems verify every critical dimension. Sheet metal parts hold bend tolerances to ±0.05 mm and laser cutting accuracy to ±0.02 mm with First Article Inspection standard on all orders
02
Fast Turnaround
Prototypes ship in 3 to 7 days and
production orders complete in 2 to 4 weeks. Dedicated cutting lines and in-house
finishing eliminate supplier handoffs that
slow delivery
03
Order Any Size
No minimum order quantity. Single-piece prototypes and production runs of 100,000+ parts go through the same equipment and inspection standards
04
Prototyping to Production
Your prototype and production parts come from the same factory. No re-qualification,
no new vendor onboarding, and no process variation when you scale from validation to volume
05
Wide Range of Materials
Carbon steel, stainless steel, aluminum,
copper, brass, and titanium sheet in gauges from 0.5 to 6 mm. Every order ships with
mill certificates and incoming inspection records
06
Cost-effective
Direct factory pricing without broker
margins. Our engineering team reviews
your design before production to identify changes that reduce material waste and processing time
