Some time ago, a customer polished a gear mold. The workpiece was an electric discharge machining process. When he took it, the overall surface condition was very poor.

The entire tooth position has obvious discharge lines, which are rough to the touch and have no finish at all. The customer requires a mirror effect. Ordinary manual grinding is not only time-consuming, but also the small teeth are thrown unevenly, which is easy to leave traces.

We directly use the Hsihwa mirror spray polishing process, without manual grinding, the abrasive can evenly cover every dead corner tooth surface of the gear, and remove all the remaining rough lines.

After the complete set of mold treatment is completed, the difference can be clearly seen by the naked eye. The original rough surface becomes delicate and smooth, with uniform reflection and transparency, and a stable mirror texture.

The customer looks at the goods on site, checks the appearance finish, all standards meet the requirements, and confirms receipt on the spot.

When encountering the problem of heavy lines and difficult to throw highlights after the gear mold is discharged, the mirror spray polishing is indeed reliable, worry-free and stable to make a standard mirror surface. If necessary, welcome to inquire about the trial throwing!
