Currently Greenstone is moving toward establishing a dedicated machining
division equipped with CNC and VMC centers. Our foundry is fully integrated
with spectrometer-based chemical analysis, sand testing, NDT (UT, MPI,
radiography), and full heat-wise traceability. Every casting undergoes 100%
testing to ensure flawless performance in service.
Prototype tools in ~2–4 weeks; production orders depend on complexity and
volumes. We’ll align to your schedule.
