Advantages
Mitsubishi EA12V
- Superior generator at FP80V with Fine Pulse 2 (FP2) vs ONA digital generator with adaptive spark control
- Backed by Mitsubishi Electric's dealer and service network for parts and support
- Mold shops burning cavities, core pins, and rib details in hardened tool steel where MC Machinery's service network and application support provide competitive advantage
ONA QX4
- Greater z travel of 350 mm (13.8 in) accommodates larger workpieces
- Superior max workpiece weight at 1,000 kg (2,205 lb) vs 700 kg (1,540 lb)
- Superior machine weight at 4,200 kg (9,259 lb) vs 3,856 kg (8,500 lb)
- More competitive pricing at $90,000 - $160,000 compared to $100,000 - $160,000
Verdict
The ONA QX4 edges ahead on specifications in this comparison, particularly in Z Travel and max workpiece weight. However, the Mitsubishi EA12V remains competitive and may be the better choice depending on price, dealer support in your area, or specific workholding and tooling considerations. Both are capable machines — the best decision comes from running your actual parts and evaluating total cost of ownership including tooling, training, and service.
