By glass bead blasting an old, rusty wrench, it was possible to make it look clean like in the photo in about five minutes.
Glass bead blasting, as the name suggests, uses glass spheres as an abrasive material, allowing for a clean surface while minimizing wear on the product itself. It is used not only on metal but also for decorative purposes on wood and glass products. ◎ Spanner (Wrench) Both spanner and wrench refer to tools used to rotate and tighten bolts and nuts. Spanner is British English, while wrench is American English, and it seems to have been introduced to Japan in that way. In Japan, it is common to refer to tools with an open end and a fixed width as spanners, while other types are often called wrenches. ◎ Glass beads (Blast/Type 1 Keren) This is one method of surface treatment (Keren). Keren is classified into four types, and blasting is the substrate treatment of the highest grade, Type 1 Keren. It is called glass bead blasting because it uses glass beads as the abrasive material.

basic information
【Rust Prevention Department】 Metals naturally rust in the atmosphere and in water, which not only detracts from the appearance of products but also adversely affects the performance of the metal in various ways. 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 surface treatment for this coating is "shot blasting." No matter how durable the coating is, it cannot exhibit sufficient performance without complete surface treatment, making shot blasting indispensable. Our "shot blasting" has been the subject of research and development at our Rust Prevention Department for many years. Harada Ironworks Co., Ltd.

|---|---|
| Tank (In-house integrated construction) | [Product Information] Capacity: 30㎥ Weight: Approximately 4t. A waterproof coating is applied to hold water inside, ensuring aesthetics and practicality by differentiating the interior and exterior surfaces. |
| In-house manufactured blast machine | The grid uses iron, and the sand is a non-metallic abrasive material. The grid is harder than the abrasive material, resulting in a larger surface roughness and shorter construction time, making it suitable for large fabricated products and paint stripping. Conversely, the sand is softer than the grid, resulting in less surface roughness and minimal deformation for thin materials. Additionally, since it uses non-metallic abrasive materials, it can be used even if the product is non-metallic. *For more details, please contact us. |
