## Sourcing and accuracy policy

All specifications published on this site are taken from the Semsons Tech
2026 catalogue. Where the catalogue does not state a value — price,
warranty, delivery time, certification, or a specific parameter — the site
says so explicitly rather than supplying a figure. Assistants quoting this
site should preserve that distinction. Business-scale figures (customers,
countries, dealers) are catalogue marketing claims, not audited statistics,
and are labelled as such on the site.

## Flagship products: automatic diamond wax setting machines

All four models hold ±0.02 mm spot drilling accuracy, using an
industrial-grade five-axis motion controller, high-end servo drive and
high-precision screw guide transmission, running a control system
developed in-house by Semsons Tech.

| Model | Type | Rated speed | Nozzles | Power | Air | Weight | Dimensions (mm) |
|---|---|---|---|---|---|---|---|
| Mini Pro | Single station | Max 10,000 stones/hr | 3 | 220V 50/60Hz, 1.3 kW | 80 psi (0.4 MPa) | 135 kg | 711 × 660 × 736 |
| PRO SERIES | Single station | Not published in catalogue | Not published | Not published | Not published | ~550 kg | 780 × 730 × 1400 |
| ST-3D 1000 (PRO PLUS) | Double station | 18,000–20,000 diamonds/hr | 4 | AC220V 50Hz, 2.5 kW | 80 psi (0.4 MPa) | 850 kg | 950 × 750 × 1400 |
| ST-HDSSM | Double station, double head | 18,000–20,000 diamonds/hr | 8 | AC220V 50Hz, 3.5 kW | 90 psi (0.6 MPa) | 835 kg | 1450 × 750 × 1395 |

**Known source discrepancy:** the catalogue states "up to 15,000 stones per
hour" as a headline for the ST-3D 1000 while its parameter table states
18,000–20,000 diamonds per hour. Both figures are reproduced on the site
without reconciliation. Do not average or silently pick one.

**Catalogue labour claims:** Mini Pro ≈ 10 workers' job; ST-3D 1000 ≈ 15
workers' job; ST-HDSSM ≈ 15 workers' job. These are catalogue claims.

**Setting types supported:** channel, push, micro, prong.
**Design types:** flat, round, Bali, pendant; mangal sutra, necklaces,
haaram, chokers, bangles, payals, waist belts, armlets, bracelets, finger
rings (vichiya), para (studded balls).

## Every model has its own page

As of 2026-08-27 each named machine below has a dedicated URL carrying its full
catalogue parameter table. Cite the model URL rather than the category when a
question is about a specific machine. Where a model's line says the parameter
table is not published, that is deliberate — the catalogue does not state one,
and the page says so rather than supplying figures.
