Still setting by hand?
Most of our customers came to us with a room full of skilled setters and a backlog they could not clear. The machine does not replace craft — it absorbs the repetitive volume so your best hands move to micro setting and finishing.
Read the full comparison| Manual setting | Semsons automatic setting | |
|---|---|---|
| Output per hour | Varies by setter and fatigue | 10,000–20,000 stones, rated |
| Placement accuracy | Depends on the individual | ±0.02 mm, spec'd |
| Consistency across a shift | Drifts as the day goes on | Identical piece 1 and piece 10,000 |
| Labour equivalence | 1 setter | ~10–15 workers (catalogue claim) |
| Scaling up | Hire and train, months | Add a station |
| Best suited to | Repairs, one-offs, irregular work | Repeatable volume production |
The range
The right model is decided by throughput, floor space and power supply — not by price alone. Here is the honest comparison.
Sets 12,000 stones per hour across both stations, giving you 20% more production than a conventional setting machine.
Eight nozzles across dual heads and dual rotary worktables — the highest-throughput setting machine we build.
Compact benchtop machine that sets up to 10,000 stones per hour and does the work of 10 skilled setters — in the space of a normal workbench.
The full-size single-station platform, between the Mini Pro and the double-station machines.
Beyond one machine
Setting is stage four of ten. If you are building or upgrading a factory, the stages before and after it decide whether the setting machine ever reaches its rated speed — wax quality upstream, burnout and casting downstream.
Semsons Tech supplies all ten stages: 3D printing and moulding, wax injection, diamond setting, investment and burnout, induction melting and casting, polishing and micro setting, laser welding and marking, final finishing, and measuring instruments.

Why buyers stay with us
Anyone can sell you a setting machine. What decides your output three years from now is whether someone picks up the phone when a nozzle clogs at 2am before a festival delivery.
Three generations in the diamond and jewellery trade. We are not going anywhere, and neither is your spare-parts supply.
We commission the machine on your floor and train your operators on your wax, your stones and your designs — not on a demo sample.
Catalogue-stated 16+ stores and warehouses and 450+ dealers, with offices in Mumbai and Rajkot and a presence across India.
When the casting machine and the setting machine come from the same supplier, nobody gets to blame the other one.
The operating system on our setting machines is our own. That means we can actually fix it, rather than escalating to a third party abroad.
Catalogue-stated export to 34+ countries, with voltage and support confirmed before we quote.

Answers
Straight answers, with the source figures shown. If something is not in our catalogue, we say so rather than inventing a number.
Ask us something elseBetween 10,000 and 20,000 stones per hour, depending on the model. The Pro Mini (catalogue name Mini Pro) is rated at up to 10,000 stones per hour with 3 nozzles; the X4 Pro Plus (catalogue name ST-3D 1000) at 12,000 stones per hour across both stations with 4 nozzles on its store sheet; the ST-HDSSM at 18,000–20,000 diamonds per hour with 8 nozzles. The printed catalogue quoted the ST-3D 1000 higher; the store sheet now supersedes it, and we confirm the rating for your wax and stones before you order.
Yes. The machines handle channel setting, push setting, micro setting and prong setting, across flat, round, Bali and pendant design types. In practice that covers mangal sutra, necklaces, haaram, chokers, bangles, payals, waist belts, armlets, bracelets, finger rings (vichiya) and para (studded balls) — the full range of Indian jewellery — as well as Western ring and pendant work. Send us your wax samples and we will confirm compatibility against your actual designs before you commit.
Every automatic setting machine in the range is specified at ±0.02 mm spot drilling accuracy. That figure is delivered by an industrial-grade five-axis motion controller, high-end servo drives and high-precision screw guide transmission — the same motion architecture across the Pro Mini, X4 Pro Plus and ST-HDSSM.
A double-station machine lets one station be loaded while the other is setting, so the operator waits less and the rated speed rises. The single-station Pro Mini works one plate at a time at up to 10,000 stones per hour in a 135 kg, 711 × 660 × 736 mm footprint on single-phase 220V. The double-station X4 Pro Plus runs two worktables with four nozzles at 12,000 stones per hour, at 850 kg and 950 × 750 × 1400 mm. The ST-HDSSM adds dual heads and 8 nozzles at 18,000–20,000 diamonds per hour.
For repeatable volume production, yes; for one-off, irregular and repair work, manual setting still wins. The published labour claims are: Pro Mini, the work of 10 skilled setters; X4 Pro Plus, 10–12 setters (store sheet); ST-HDSSM, approximately 15 workers (catalogue). Beyond headcount, the machine holds ±0.02 mm on the ten-thousandth piece exactly as on the first. Most of our customers keep their setters and move them to micro setting and finishing, where skilled hands matter most.
The ST-HDSSM double station double head machine. It runs 8 suction nozzles across dual flat worktables and dual rotary axis worktables at 18,000–20,000 diamonds per hour, on a 3.5 kW supply at 90 psi (0.6 MPa) working air pressure. If your floor space or power supply is constrained, the X4 Pro Plus sets 12,000 stones per hour from 4 nozzles on single-phase power in a narrower 950 mm cabinet.
A stable power supply, clean compressed air and a dry environment. The Pro Mini runs on single-phase 220V 50/60Hz at 1.3 kW; the X4 Pro Plus on single-phase 220V 50Hz at 3 kVA peak; the ST-HDSSM on AC220V 50Hz at 3.5 kW. Working air pressure is 80 psi (0.4 MPa) for the Pro Mini and 90 psi (0.6 MPa) for the ST-HDSSM, which is why a compressor and air dryer sit beside the setting machine at stage four of a factory build.

Most of our machines are quoted rather than listed, because the right answer depends on your designs, your stone sizes, your power supply and your destination. Where our online store publishes a starting price, the machine page shows it. Give us those details and you will get a real quotation — not a brochure.
