Metal Melting



Precious Metals

This photo shows a lip axis pouring unit in operation.In this case, a precious metal is being drawn off into a smaller crucible so that it can be decanted into ingot moulds.

 

Here the metal is being poured into the moulds.  The medium frequency induction heater can be seen behind the "pour master".

This is a twin station precious metal melting system.  The induction heater is at the rear of the picture.The hand operated lip axis pouring unit on the left uses a clay graphite crucible for gold melting and the one on the right is designed for melting platinum and uses a Zirconia crucible.


Continuous Casting

Metals and precious metals can be continuously cast in a variety of forms.This shows a silver bar and the stock grain that is used to cast the bar.The bar was produced on a machine that we designed and built for use in the precious metals industry.

Top view of crucible

This photo shows a typical continuous casting machine.  The crucible is in the thermally insulated box that is immediately in front of the man, to the right of this is the control unit and the induction heater can be seen on the extreme right hand side. 


Centrifugal Casting

Centrifugal casting machines are used in the manufacture of jewelry, dental and industrial products.The induction heating power unit is built into the base of the equipment.As many of these machines are for use in small laboratories, the equipment has been designed to split into two parts so that the machine can easily pass through a small doorway.Typical metals processed with this equipment are gold, silver, platinum, cobalt and their alloys.


Spectral Analysis

This photograph shows a small workhead, crucible and tweezers that are typically used in metallurgical laboratories for preparing metal samples for spectral analysis.Heating energy for these small melting units is normally supplied from our 1 or 2kW power supplies.  This type of equipment is also used in schools, technical colleges and universities to economically demonstrate the principles of induction metal melting.
