Pain Point 1 – Sky‑High Prices
Most suppliers charge a 20‑35% premium for standard casings, eroding your ROI and inflating project budgets.
Pain Point 2 – Inconsistent Quality
Quality deviations such as dimensional tolerance > ±0.2 mm and surface defects increase re‑work rates by up to 27%.
Pain Point 3 – Lengthy Lead Times
Traditional foundries need 4‑6 weeks for tooling and production, delaying plant commissioning and causing opportunity loss.
