Jewellery Manufacturing Full Factory Setup

Ten stages, in production order: (1) designing and moulding — 3D printer, resin, laser cutting machine; (2) moulding — vulcanizer, liquid silicon, aluminium frame; (3) wax injection — wax injector, wax, vacuum pump, spru wax mould, shoulder iron; (4) diamond setting — diamond wax setting machine, compressor, air dryer, tray setting; (5) mixing and burning — auto gypsum vacuum mixer, gypsum cleaner, flask, flask tong, rubber base, investment powder, burnout furnace; (6) melting and casting — casting machine, melting machine, graphite and ceramic; (7) hand polishing and micro setting — polishing motor, ring expander, tweezers and pliers, bur tools, saw blade and graver, micro setting machine and microscope; (8) shouldering and marking — laser marking, laser welding, tick welding, hydra welding; (9) final polishing — magnetic tumbler, vibrator, barrel polish, electro polish, consumables; (10) measuring instruments — gold testing, weighing scale, caliper and gauge, metal locator, magnifier, currency counting machine.

Follow production flow, not price. A setting machine bought before you can produce consistent wax will sit idle, because bad wax upstream defeats ±0.02 mm placement accuracy downstream. If you are upgrading an existing floor rather than building new, the usual sequence is: fix the bottleneck stage first, confirm the stage before it can feed it, then confirm the stage after it can absorb the new output. We will walk your floor with you before recommending anything.

Most of our customers do exactly that. The common path is to start by outsourcing casting and buying the setting and finishing equipment, because that is where quality and labour cost bite hardest; then bring casting in-house once volume justifies the induction melting and burnout investment. Tell us your budget and your monthly volume and we will map a phased plan rather than quoting the whole floor at once.

Power, compressed air and water cooling are the three that catch people out. Setting machines need 80–90 psi (0.4–0.6 MPa) working air pressure, so a compressor and air dryer are mandatory, not optional. Induction melting above 2 kg capacity needs three-phase 440V/50Hz — 7 kW for the IG-3/4 and 12 kW for the IG-10/20 — and every induction model needs a water chiller, typically 630 × 630 × 960 mm. Plan these before you plan the layout.

Work from the machine footprints. A Mini Pro setting machine is 711 × 660 × 736 mm at 135 kg; an ST-3D 1000 is 950 × 750 × 1400 mm at 850 kg; an ST-HDSSM is 1450 × 750 × 1395 mm at 835 kg. Add the induction melting unit and its chiller, burnout furnace, polishing line and bench positions, plus clear operator access on every machine. Send us your floor plan and target output and we will lay the equipment out against it.

We supply all ten stages. Our 2026 catalogue covers more than 2,000 products across diamond setting, laser marking and cutting, laser and spot welding, XRF gold analysis, 3D printing and resins, wax injection, investment and burnout, induction melting and vacuum casting, polishing, cleaning and finishing, enamel dispensing, production machinery, gemological instruments and consumables. Some gemological testers we supply are recognised third-party brands rather than our own manufacture, and we tell you which is which.

Yes. We commission machines on your floor and train your operators on your own wax, your stones and your designs — not on a demonstration sample. The control system on our setting machines is self-developed by Semsons Tech, which means support does not depend on escalating to a third party abroad. We have served the industry since 1978.
