Virus infection control products using natural material plaster, inactivating 99.9% of viruses attached to the surface in 15 minutes.
Traditional Japanese wall material, plaster, possesses various functions due to the unique texture of its natural materials and the properties of its main component, slaked lime. One of these functions is its antiviral and antibacterial properties. You may have seen images of white powder being spread when outbreaks of swine fever or avian influenza occur; that white powder is slaked lime, the main ingredient of plaster. <Features of the Plaster Power Series> 1. Instant effectiveness that inactivates over 99% of viruses adhered to the surface within 15 minutes. 2. Infection control measures that are communicated to customers (function printed for clarity). 3. Easy plaster effect that requires only cutting and sticking. Please use it in toilet booths, fitting room walls, handrails, handles, doorknobs, etc., in facilities used by a large number of people, such as commercial facilities, medical facilities, nursing facilities, educational institutions, and evacuation centers. (Excludes outdoor and water-related areas.)

Hot forging: Low deformation resistance, allowing for the forging of complex-shaped parts! Cold forging: Reduces material loss, shortens processing time, and enables cost reduction.
■Hot Forging A processing method where metal is heated and softened before being compressed and formed, resulting in low deformation resistance and the ability to forge complex-shaped parts. Compared to other forging methods, it offers the highest degree of freedom, allowing us to provide inexpensive and high-quality products. ■Cold Forging A processing method where metal is compressed and formed at room temperature, allowing for the production of products with higher precision compared to hot forging. It reduces material loss compared to cutting processes, shortens processing time, and enables cost reduction of the processed products. We provide high-quality products even for complex shapes. 【Manufacturing Examples】 ■Driven Gear Forging ■Materials: SS, SC, SK, SCM, SKS, CRV ■Processing Accuracy: Forging only ±0.1mm ■Surface Treatment: Shot blast finishing, etc. * We can propose surface treatments according to your requirements. * For more details, please refer to the PDF document or feel free to contact us.
No water leakage even when screwed in at an angle! Supports a maximum tilt angle of 15°!
The screw product "Sharaku" maintains its water-stopping effect even when driven at an angle. The spherical part below the head closely adheres to the entire circumference of the counterpart hole (washer), allowing for the maintenance of the water-stopping effect. Since the entire spherical part can uniformly apply pressure to the counterpart hole (washer), the sealing effect with the packing is enhanced. It can accommodate a maximum tilt angle of up to 15°. Depending on the application, it can be shaped to the "Hirata standard" tip. With the adoption of a special cutting edge (high-catch tip), it can easily penetrate even at the knots of rafters. Even with four layers of colonial, it can penetrate sufficiently. By shaving with the special cutting edge, it becomes less likely to cause wood splitting or cracking in the colonial. For more details, please contact us or refer to the catalog.
