Alternatives
The mid-capacity IGBT melter - 3 to 4 kg per cycle on three-phase supply.
The largest melter in the range - 10 to 20 kg per cycle, with a dedicated tilting unit.
Melts under induction and pours from the bottom under vacuum - the cleanest metal reaches the flask first.

Answers
Our catalogue describes induction melting as fast, clean, uniform and more controllable, capable of supporting purification stages and reducing heat-induced oxidation. In day-to-day terms: flameless and silent operation, reduced thermal shock, better productivity, and a bench an operator can work at for a full shift.
Yes. Every induction model in the range is specified with a water chiller as its cooling system, and the stated machine weight includes it. Factor the chiller footprint into your layout before you commit to a position on the floor.
The IG-1/2 is specified at Single phase 230V / 50Hz, 3.5 kW output. Confirm your incoming supply before selecting a capacity band - moving between single and three phase after the machine is built is the single most expensive change a buyer makes in this category.
Rated power is 3.5 kW. It runs on Single phase 230V / 50Hz. Confirm your incoming supply before you order — voltage and phase are the two things that most often need changing after a machine has already been built.
It weighs 120 kg. Allow clear working space on the operator side, plus access for any support equipment — compressor, air dryer or water chiller — when planning your layout.
Yes. We commission the machine on your floor and train your operators on your own material and your own designs rather than a demonstration sample. Semsons Tech has served the diamond and jewellery industry since 1978, and on our setting machines the control system is self-developed, so support does not depend on a third party abroad.
We do not publish delivery times, spare-parts pricing or AMC terms, because all three depend on configuration, destination and what is on the floor at the time. They are confirmed in writing on your quotation rather than estimated here. Ask for them explicitly when you enquire and you will get them in writing.
We quote per configuration and destination rather than publishing a list price, because voltage, tooling, spares package and shipping all change the figure. Send us your requirement through the form on this page and you will receive a written quotation.
