Jewelkon manufactures Loose Stone Detector with Over-Load Protection. The Jewellery pieces have to undergo transport and handling, before reaching to customers hand and are subjected to various vibrations of harmonic pattern. These vibrations are primarily generated due to rotating, pulsating oscillations caused by land, vehicles, aircrafts, ships, handling of machineries, etc. This vibration gives rise to separation of diamonds from the pieces which increases the rejection ratio. Vibration Simulation is the technique use to simulate these vibration conditions for testing of the pieces in the factory, before final dispatch, by quality control department, thus the Loose Stone Detector is used. Vibrations of discreet frequency are being generated for a given period of time to test the setting of the pieces. Jewelkon also manufactures alloys of different compositions, rhodium plating solutions, gold plating solutions, palladium plating solutions, alloy plating solutions, etc. Under brand name of Ultra-Shine.
