basic information
【Rust Prevention Department】 Metals naturally rust in the atmosphere and in water, which not only detracts from the aesthetic appeal of products but also adversely affects the performance of the metal in various ways. To prevent such issues, it is necessary to protect the surface of the metal by some means. In recent years, significant advancements in technology have led to the development of highly durable coatings. One essential process that is always performed as a pre-treatment for this coating is "shot blasting." No matter how durable the coating is, it cannot perform adequately without complete surface preparation, making shot blasting indispensable. The "shot blasting" process has been the focus of long-term research and development in our Rust Prevention Department. Harada Iron Works Co., Ltd.
