Casting Service

 

DPMEX offers a complete suite of services that will satisfy all of your jewelry casting requirements. We use the latest casting equipment available to the trade. All of our casting are done in a oxygen free environment This reduces porosity and pitting caused by oxidization. We use several casting methods depending on the size and intricacy of your model. We use vacuum assist, pressure over vacuum, and centrifugal casting machines.  We cast in pink, yellow, white, green gold, platinum, palladium, sterling silver, titanium, and stainless steel. We can finish your casting or send it back unfinished. We also do sizing, rhodium plating, refinishing, pave stone stetting, micro pave, channel setting, and bezel settings.
