Our Manufacturing Facility

Our 2000+ product specifications are manufactured across a comprehensive lineup of Japanese Mazak CNC equipment and supporting machinery:

Our Japanese Mazak CNC equipment enables production precision that improves efficiency by 100% and reduces scrap rates by 30% compared to conventional machining — translating to better quality and competitive pricing for our customers.

Quality Control Process

Quality at ONEMO is built into every stage of production — not just an inspection step at the end:

1. Raw Material Inspection
All incoming stainless steel (SS304, SS316L) is verified against material certificates (EN 10204 3.1). Chemical composition and mechanical properties are confirmed before any material enters production. We maintain full material traceability from mill to finished product.

2. In-Process Inspection
During manufacturing, our QC team conducts regular patrol inspections following written work instructions. Dimensional accuracy, surface finish (Ra), and thread quality are checked at each operation stage using calibrated instruments.

3. Hydrostatic Pressure Testing
All valve products undergo hydrostatic pressure testing to verify body and seat integrity. Standard test pressure: 1.5 x rated pressure (15 bar for standard 10 bar valves). Test certificates are available upon request.

4. Final Inspection and Traceability
Finished products receive 100% visual and dimensional inspection before release. Each product is marked with a heat number and production date, ensuring full traceability from raw material to shipped product.

ONEMO operates under certified quality management systems:

• ISO 9001:2015 — Quality management system for design and manufacturing of sanitary valves and fittings
