After these treatments, the seeder can not only work stably in various harsh environments, but also significantly extend its service life and reduce maintenance costs.
In addition, surface treatment technologies such as sandblasting are also widely used in the production of vulnerable parts such as planting drill bits. Through sandblasting, the surface roughness of the drill bit is improved, enhancing its cutting performance, while improving wear resistance and extending service life.
