- High unit cost: Imported caps often carry a 25‑35 % price premium.
- Quality inconsistencies: Dimensional tolerance > ±0.2 mm leads to leakage and re‑work.
- Long lead times: 4‑6 weeks from order to delivery slows line change‑overs.
- Limited material options: Most suppliers only offer cast iron, lacking stainless‑steel or aluminum choices.
- Regulatory risk: Missing CE, RoHS or ISO certifications can halt shipments.
Result: Increased OPEX, production downtime, and compliance headaches.
