Short answer: buy the double-station X4 Pro Plus when the machine will run all day on continuous orders; buy the single-station Pro Mini when it will run in batches, in mixed sizes, or in a workshop where floor space and power are tight. The double station's advantage is that one station is being loaded while the other sets, which removes the waiting between batches. Its cost is 850 kg of machine on a 950 × 750 mm footprint.

Where the single station wins
- Space and power. It sits on a normal workbench, weighs 135 kg and draws 1.3 kW from a single-phase socket. A Zaveri Bazaar or Andheri workshop on an upper floor can install it without structural or electrical work.
- Batch work and job work. Mixed designs and mixed sizes in short runs do not benefit from a second station, because the changeover is at the model, not at the station.
- First step off manual. The operator learns it in about an hour, and it proves the workflow (model preparation, silicone, trays, nozzles) before a larger investment.
Where the double station wins
- Continuous orders. While one station sets, the other is loaded. Over a shift that is the roughly 20% capacity advantage over a conventional single machine, with no idle time between batches.
- Long feeds. Four trays holding 12,800 stones run a long stretch without reloading.
- Multi-colour and multi-size designs. Up to 8 colours or sizes in one run, or a combination, so a design with white and coloured melee is set in one pass.
What is the same
Both machines place to ±0.02 mm, run from a touchscreen, work on gold, silver, brass and other metals, set 99% of market jewellery styles, take the same sorting trays, suction nozzles, setting silicone and mounting bases, come with on-site installation and operator training, and carry a 12-month extendable warranty. Consumables ordered for one fit the other.
A simple decision rule
If the machine would sit idle waiting for the next batch of models, the single station is the right size and the money saved is better spent on a second set of trays and a stock of nozzles. If the models are ready before the machine is free, the second station is what you are paying for. Send stone sizes, monthly volume and current setting method to Semsons Tech for a direct recommendation.
Frequently asked questions
Can the Pro Mini be upgraded to a double station later?
No. They are different machines. A unit that outgrows the Pro Mini usually keeps it for job work and short runs and adds an X4 Pro Plus for the continuous line, since both use the same consumables.
Does the double station need three-phase power?
No. The X4 Pro Plus runs on single-phase 220 V at 50 Hz with a 3 kVA peak draw. The Pro Mini draws 1.3 kW on single-phase 220 V at 50 or 60 Hz.
How much floor space does each machine need?
The Pro Mini is 711 × 660 × 736 mm and 135 kg, so it sits on a workbench. The X4 Pro Plus is 950 × 750 × 1400 mm and 850 kg, and stands on the floor; its weight is what keeps it vibration-free at full speed.
