Casting Silver and Gold with Ultraflex PressCast 5G

Casting Silver and Gold with Ultraflex PressCast 5G

One of our customers in India, Swarn Akruti, is thrilled with their new PressCast 5G. Ultraflex Power Technologies salesman, Ajay Mehta, recently visited with Swarn Akruti’s owner, Mr.. Dilip Gupta, at their facility and was able to see their excellent work of casting silver and gold jewelry firsthand. These Silver and Gold Castings are beautiful work!

The PressCast 5G has many features that make it ideal for casting silver and gold in jewelry manufacturing, including casting in argon in a vacuum to ensure no oxidation of the finished parts; an internal thermocouple to monitor temperature; and pressure injection of the molten metal into the mold. With its precise vacuum / pressure profile during the casting process, the PressCast 5G produces flawless silver and gold castings, as shown in the pictures below.

Overview of Casting Silver and Gold with PressCast 5G

Material Loading image
Ingots or scrap are loaded prior to process initiation.

Air purging image image
To secure optimal environment for clean and successful casting, both melting and casting chambers are consecutively deep vacuumed (2) and refilled with argon (3). This process is cycled several times to make sure all oxygen is entirely evacuated. The last stage is backfilling the chambers with argon to prepare them for melting and casting.

Melting image
Heating is turned on as soon as both chambers are backfilled with argon and the flask is raised up to position. An optical sensor is continuously monitoring the alloy temperature as a built-in temperature controller is following the best temperature profile. The alloy is also visible through a view-finder for better process control.

Injection and Compression image
When the molten alloy reaches casting temperature, an injection and compression cycle is started by raising the plunger and applying the right pressure and vacuum. Pressure is applied to the melting chamber, while vacuum is pulled from the casting chamber. That eliminates miscasting and significantly reduces shrinkage porosity. For the best results, a precise vacuum/ pressure profile is followed for the whole duration of the injection and compression phase.
