If you are buying one used machine from China, the choice is usually between Haitian and PowerJet. Both are mainstream Chinese brands, both run servo-hydraulic lines, and both appear constantly on the used market. The honest answer is that condition and year matter more than the badge — but the brands do differ in ways that should shape your decision.
Quick Verdict
| Haitian | PowerJet | |
|---|---|---|
| Installed base | Largest in the world; parts and mechanics everywhere | Large in China, smaller abroad |
| Parts availability outside China | Best of any Chinese brand | Good for common parts; confirm controller parts first |
| Used price position | Carries a brand premium above Chinese-brand anchors | Often better value per ton on the used market |
| Best for | Buyers who want the safest resale and service network | Buyers who want the most machine for the budget |
| Typical used lines | Mars (MA), Jupiter (JU), Venus (VE) | BJ series (BJ-S6 servo line) |
Installed Base and Service
Haitian’s advantage is scale: it is the world’s largest injection molding machine maker by volume, so its machines, parts and service knowledge are the most widely available. In most markets you can find a technician who has worked on a Mars machine, and common seals, heaters and pumps are obtainable locally. PowerJet’s installed base is large inside China and growing in export markets, but outside China you should confirm parts availability for the specific controller and servo drive before buying — a question worth asking any seller, including us.
Price
Our price index tracks Chinese-brand servo machines overall — about US$9,000–9,500 asking for the 160T class and US$14,500–15,000 for the 250T class in October 2026, FOB China. A comparable used Haitian typically asks above those anchors; a comparable used PowerJet typically asks at or near them. The gap is a brand premium, not a quality gap — it pays for the larger service network, and it is worth paying if service access matters more to you than the purchase price.
What Matters More Than the Badge
Three things decide a used machine’s value more than its brand: year and generation (a 2020 Mars II and a 2012 Mars I are different machines); condition evidence (test video, measured wear, service records); and the seller’s process (inspection, refurbishment grade, production trial before shipment). A well-documented PowerJet beats a poorly documented Haitian every time. Compare the actual units — their pages, photos and test status — not the logos.

FAQ
Is a used Haitian always better than a used PowerJet?
No. Haitian wins on service network and resale; PowerJet wins on value per ton. For a general molding factory with local service options, a documented PowerJet is often the smarter buy. For a buyer who needs guaranteed parts access in a market with no Chinese-brand service, Haitian is the safer choice.
Which series should I compare?
PowerJet’s BJ-S6 servo line against Haitian’s Mars series — both are mid-range servo-hydraulic lines in the 90T–530T band, and the comparison is meaningful tonnage-for-tonnage.
Does MoldMach test both brands the same way?
Yes. Every machine, whatever the badge, is inspected in our Yiwu workshop, refurbished to a stated A/B/C grade, and dry-cycle & purge tested before it is offered; a production trial with your mold runs after deposit, before shipment.
