Advantage

■ clean and smooth, not hurt to the mechanical precision of work piece.
■ high mechanical intensity, hardness, flexibility
■ it can be reused several times, the same effect and is not easily broken.
■ uniform size, after blasting sand around the device to maintain a uniform brightness effect, not easy to leave a watermark.
■ high purity and good quality meet the international standard.
■ stable chemistry property, not pollute the metal processed.
