Get Free Quote in 24 hWhy Your Production Is Stalled – Core Pain Points
1. High Material Costs – Most suppliers charge a premium for SS304, inflating your BOM by up to 25%.
2. Inconsistent Casting Quality – Dimensional variance (>0.2 mm) leads to re‑work, raising labor costs by 15%.
3. Lengthy Lead Times – Traditional foundries average 45‑60 days, delaying project roll‑out and hurting ROI.
