QC and Measuring
Sample making is a very important role in the jewelry business. We advise customers to make samples before producing larger quantities. By making a sample, we can experience and try the product firsthand. It also allows us to review and evaluate all aspect of the product, so the product can hit a great success in the market.
Molding
The mold allows us to produce a uniform product in a faster time. SUNSRI provides two types of molding, Rubber and Silicone Molding. We use rubber to mold metal masters such as silver, copper, or brass, but we have to use silicone to mold masters with a softer material like wax, clay, or resin. Our molding technician will ensure the molds are strong, flexible and reusable, so it’s able to produce identical models time after time.
2. Production
Casting
Lost-wax casting, also called cire-perdue, is a method of metal casting in which molten metal is poured into a mold that has been created by means of a wax model. With a proper procedure, lost-wax casting is able to produce a large amount of intricate design jewelry with a smooth surface in a shorter time. SUNSRI team always strives to ensure the casting process runs in a proper procedure in order to produce high-quality casting pieces.

Anti Tarnish Coating and E-Coating
Anti Tarnish Coating is a medium based on nano-technology for protecting silver against tarnishing. Special nanopolymers absorb on the silver surface and cross-link to form a protective layer of a few nanometers thickness. The invisible layer protects the base material from oxidation and discoloration.
The e-coating is infused with nano-ceramic particles which are undetectable by the human eye. These particles make the coating more abrasion-resistant than traditional coatings and they provide a metallic sensation to the touch. The metal underneath will remain perceivable and bring the advantages of antitarnish, Biologically safe, skin-friendly, and hypoallergenic.
SUNSRI offers both Anti Tarnish Coating and E-Coating services at a decent price.
