By glass bead blasting an old, rusty wrench, it was possible to make it beautiful like in the photo in about 5 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 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 types 1 to 4, 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. Harada Ironworks Hiroshima Official Link

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 must be performed as a surface treatment for this coating is "shot blasting." No matter how durable the coating is, it cannot demonstrate its full potential without complete surface preparation, making shot blasting indispensable. Our company’s Rust Prevention Department has been engaged in research and development of this "shot blasting" for many years. Harada Ironworks Co., Ltd.

|---|---|
| Tank (In-house integrated construction) | [Product Information] Capacity: 30㎥ Weight: Approximately 4t. It has been coated with water-resistant paint to hold water inside, ensuring both aesthetics and practicality by distinguishing between the interior and exterior surfaces. |
| In-house manufactured blast machine | The grid uses iron, and the sand uses non-metallic grinding materials. The grid is harder, 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 grinding materials, it can be used even if the product is non-metallic. *For more details, please contact us. |
