When should you repair your blow mould vs buy a new one? Expert guide from Ultra Mould's workshop team — covering damage types, repair feasibility, costs, and turnaround times.
Every blow mould manufacturer faces the same question at some point: when the mould shows defects — flash, marks on bottles, leaking bases, poor neck finish — do you repair it, or buy a new one? The answer depends on the nature and extent of damage, the mould's age, and the cost comparison.
As a rule of thumb: if the mould cavity is structurally intact and the damage is to surfaces, edges, neck inserts, or cooling channels, repair is almost always more cost-effective than replacement. A full mould replacement costs ₹40,000–₹2,00,000+, while most repairs cost ₹5,000–₹30,000 and can extend mould life by 3–5 years.
| Damage Type | Repairability | Est. Cost | Time |
|---|---|---|---|
| Cavity scratches / marks | ✅ Easy to repair | ₹3,000–8,000 | 2–4 days |
| Parting line flash | ✅ Easy | ₹5,000–12,000 | 3–5 days |
| Neck finish worn / chipped | ✅ Standard repair | ₹8,000–20,000 | 3–5 days |
| Base insert wear | ✅ Replace insert | ₹10,000–25,000 | 4–6 days |
| Cavity dent (small) | ✅ Weld + re-machine | ₹15,000–40,000 | 5–8 days |
| Cooling channel blocked | ✅ Chemical clean | ₹5,000–10,000 | 2–3 days |
| Cavity crack (through-wall) | ⚠️ Sometimes possible | ₹25,000–60,000 | 7–10 days |
| Cavity fully crushed | ❌ Replace recommended | New mould cost | 4–6 weeks |
