Jewellery sector

As in medical and preci­sion cast­ing, jewellery cast­ings are gener­ally produced using the lost-wax cast­ing tech­nique. This tech­nique was already used in ancient times for produc­ing fili­gree works of art. Today, this process is still valid and is even success­fully used in mass produc­tion. Many smelt­ing plant manu­fac­tur­ers take advan­tage of our many years’ expe­ri­ence and have the crucibles for their plants manu­fac­tured by GTS. Further­more, in close collab­o­ra­tion with the jewellery indus­try, GTS has devel­oped high-qual­ity crucibles that are partic­u­larly suit­able for melt­ing plat­inum. The special nature of their qual­ity guar­an­tees a long service life in terms of reusabil­ity. This ensures econom­i­cal use, so that these crucibles enjoy world­wide demand. Our alumina anneal­ing dishes and crucibles are used for refin­ing natural rubies.
