One Equipment Choice Affects a Decade of OPEX
1. Two Machines, Two DNA Profiles
The Molins MK9 and Hauni PROTOS 70 are the two most common cigarette-making machines encountered by small-to-mid-size tobacco factories.
| Dimension | Molins MK9 | Hauni PROTOS 70 |
|---|---|---|
| Origin | United Kingdom (1978) | Germany (1970s) |
| Output | 4,500-5,500 cigs/min | 7,000 cigs/min |
| Global Installed Base | ~500-800 units | ~1,000-1,500 units |
| New Machine Status | Discontinued | Discontinued |
| Used Price Range | $80K-250K | $150K-500K |
| Maintenance Difficulty | Low (simple mechanics) | Moderate |
| Spare Parts Supply | Abundant (multiple suppliers) | Abundant (multiple suppliers) |
2. Spare Parts Cost Comparison — 5 Key Categories
| Spare Part Category | MK9 Monthly Cost | PROTOS 70 Monthly Cost |
|---|---|---|
| Cutting Blades | $400-600 | $600-900 |
| T-Tube / Tongue Assembly | $250-400 | $350-600 |
| Suction Tapes | $150-300 | $300-500 |
| Filter Attachment (Max S) | $300-500 | $400-650 |
| Electrical Components | $200-400 | $350-600 |
| Monthly Total | $1,300-2,200 | $2,000-3,250 |
PROTOS 70 spare parts costs are approximately 50% higher than the MK9, but output is also 30-50% higher.
3. Alloy Differences in Critical Wear Parts
Cutting Blades
| Parameter | MK9 Recommended | PROTOS 70 Recommended |
|---|---|---|
| Recommended Material | HSS (High-Speed Steel) | TCT (Tungsten Carbide) |
| Hardness | HRC 58-62 | HRA 88-92 |
| Typical Service Life | 2-3 weeks | 4-6 weeks |
| Unit Cost | $80-150 | $150-300 |
T-Tube Assembly
| Parameter | MK9 | PROTOS 70 |
|---|---|---|
| Material | Coated Carbide | Full Carbide |
| Service Life | 6-8 months | 8-12 months |
| Unit Cost Per Set | $500-800 | $800-1,200 |
4. TCO Comparison (5-Year View)
Assumptions: 6,000 operating hours per year, 80% capacity utilization
| Cost Category | MK9 (5 Years) | PROTOS 70 (5 Years) |
|---|---|---|
| Equipment Purchase | $150K | $300K |
| Total Spare Parts | $90K-132K | $120K-195K |
| Energy | $35K | $45K |
| Maintenance Labor | $45K | $55K |
| 5-Year TCO | $320K-362K | $520K-595K |
PROTOS 70's 5-year TCO is approximately 60% higher, but its output is approximately 40% higher.
5. How to Choose — Guidance for Small-to-Mid-Size Factories
Choose MK9 When:
- Monthly output requirement < 30 million cigarettes
- Limited maintenance team experience
- Budget-sensitive operation
Choose PROTOS 70 When:
- Monthly output > 50 million cigarettes
- Experience with German equipment maintenance
- Higher automation level required
Spare Parts Strategy Recommendations
Regardless of which machine you operate:
- Cutting/wear parts → Upgrade to carbide, extending service life 2-3x
- T-Tube / tongue assemblies → OEM-grade precision, provide original samples for reverse engineering
- Generic items (bearings/seals) → Source standard specifications independently
- Build critical spares inventory: 2 sets of blades + 1 T-tube set + 2 suction tapes
