Welcome to SJ Jewelry – a jewelry manufacturer that draws on over 10 years of industry expertise to bring you unique, quality electroplated jewelry .
we’re proud to design all of our jewelry in-house and have all the metal jewelry manufactured in our environment-friendly electroplating factory.
Spray salt water containing (5±0.5)% sodium chloride with a pH value of 6.5 to 7.2 through a spray device, let the salt spray settle on the test piece to be tested, and observe its surface Corrosion state after a certain period of time (24 hours to 72 hours).
The temperature of the test box is required to be (35±2)℃, the humidity is greater than 95%, the amount of mist reduction is 1 to 2 mL/(h·cm2), and the nozzle pressure is 78.5 to 137.3kPa (0.8 to 1.4kgf/cm2).
When the test piece is placed in the box,do not directly contact the box body,but should be suspended or placed on a special shelf.
The sample holder is made of glass, plastic and other materials. The material for hanging the sample should not be metal, but rayon/cotton fiber or other insulating materials should be used.
Clamp the pencil in the instrument so that the pencil protrudes 5mm, and then place the instrument on the surface of the sample. Press the left key first, and the test platform moves to the left. The adjustment knob can be adjusted to the required test speed according to the test needs. The tachometer displays the motor speed in real time. Each time the motor rotates, the platform moves 1.75mm, and the sample to be tested is clamped On the test platform, click the right button, the test pencil slides on the sample plate at a certain speed, and it stops automatically when it reaches the end point.
Note : 1. Device is made in Germany.
2.Only standard 4H pencil used.
Put the product in the box, press the button (UV key, D65 , etc.) to compare the color of the finished product under different lights to determine whether the finished product meets the requirements.
Note: International color standard applied in the system.

PVD = Physical Vapor Deposition,which is a process carried out in high vacuum at temperatures between 150 and 500 °C.
PVD is applied similar to electroplating where an electrical current is passed through the piece that is being plated. The pieces are sealed in an airtight chamber where a vacuum is created. In this vacuum negative voltage attracts the positive ions and inert gas that is introduced, which creates the environment necessary for the deposition process to occur.
With PVD coating you get a highly durable, long lasting, scratch resistant piece. PVD is more expensive than traditional plating methods due to the more laborious and expensive plating processes.
