1, polishing: to overcome defects and deburring and make the surface bright role.
2, sandblasting: aluminum surface treatment is used to overcome and cover up some defects of aluminum alloy in the machining process and to meet the customer's special requirements for the appearance of the product. There are glass sand, tungsten sand, etc., presenting different feelings, similar to the rough texture of hairy glass, fine sand can also show high-grade products.
3, metal plating method: more common, while there are sanding after plating treatment process.
4, the car pattern: aluminum surface treatment is the mold molding processing again after the treatment, the use of lathe processing out of the grain, into the body of the performance of a very regular texture characteristics.
5, rubbing grain: there is called wire drawing, performance is similar to the car grain, are formed on the surface of the smooth continuous pattern, the difference is that the car grain is shown as a ring pattern, rubbing grain is shown as a straight line batch of flowers.
6, oxidation (color): aluminum surface treatment oxidation of the use of two aspects, to enhance the physical properties, can achieve the purpose of color.
