A ceramic mold is prepared using the previous max model which is heated, melted and then evaporated. After the ceramic mold is hard enough and all the wax has been evaporated, molten metal of your choice is poured into the hardened ceramic mold. This process is known as Investment casting or lost wax casting. Jewellery has been manufactured using this process for over 5000 years, and the artisans at laser jewel have mastered this skill to perfection. Using this investment casting process, we created the most beautiful pieces of jewellery with the best turnaround rates.
Depending upon the base metal of your choice required for the project, there are two types of investment casting methods to choose from.
LOW TEMPERATURE Casting
For Soft metals like Gold, Silver and Bronze the melting temperatures are much lower compared to the temperatures used to melt much harder and durable metals. This means that the material needs to be cast at a relatively low temperature (1,500 - 2,100 degrees Fahrenheit). For this method, we use a gypsum-bonded investment and the melted metals are gravity-poured with the help of a vacuum assist and pressure over pour, which is both metal efficient and minimizes the possibility of defects such as scaled or porous skin.
HIGH TEMPERATURE Casting
When working with more durable metals, such as rhodium, the materials must undergo higher temperatures in order to melt down. Anything that melts within the range of 2,200 - 3,800 degrees Fahrenheit falls under our high temperature category. For this method we use a phosphate-bonded investment to cast and the melted metal is centrifugally-poured with a vacuum.
