Casting
In waxing (production of wax replicas from the rubber mould), semi-automated Japanese wax injection machines are used which can be finely adjusted for accurate temperature and pressure settings for each injection. As the waxing staff have been trained to keep a record of temperature and pressure measurement for each new design, we can replicate the same measurements for each waxing, thus reducing shrinkage problems and so attain a particular weight point if required by the customer.
 
Each and every wax item is checked for high quality prior to cast. Prepared wax trees are kept in a closed box which prevents the contact of dust with the wax trees until investing.

Investing: The investment process is carried out with strict timing according to industrial standards. Separate mixers are used for platinum and gold investments. Air bubbles in investment mixture are removed by a vacuum vibrator machine prior to investing the wax trees in order to obtain high quality castings.
 
De-waxing is accomplished prior to oven burn out and this ensures smooth surfaces with less or no porosity
 
Casting: Two different types of Japanese machines are currently being used for the casting process. A centrifugal casting machine is used for platinum casting while a gravitational casting machine is used for gold castings. Highly skilled labour used in casting ensures the quality of casting while maintaining minimum cast and metal waste during the process. Cast items are checked for quality using qualitative methods as well as quantitative methods such as assaying, to maintain international standards.

We carefully inspect all jewelry at this point to ensure both ASKR Jewelry and International Quality Standards are met, to guarantee quality assurance.
