The comparison board shows the effects after the application of grid blasting and sand blasting. The grid uses metal-based abrasives, while the sand uses non-metal-based materials.
◎Grit Blast (Blast/Type 1 Surface Preparation, English: Grit blast) One of the surface treatment methods (surface preparation). There are four types of surface preparation, from Type 1 to Type 4, and grit blast serves as the substrate treatment for the highest grade, Type 1 surface preparation. ◎Sand Blast (Blast/Type 1 Surface Preparation, English: Sand blast) One of the surface treatment methods (surface preparation). There are four types of surface preparation, from Type 1 to Type 4, and sand blast serves as the substrate treatment for the highest grade, Type 1 surface preparation. For stainless steel and cast iron specifications, we can accommodate lot sizes from 1 to 1,000 pieces. Grit blast uses hard abrasives, resulting in a rougher surface finish. It also shortens construction time, making it suitable for large fabricated products and paint stripping. On the other hand, sand blast uses softer abrasives, resulting in a smoother surface finish. It is suitable for thin materials and those with minimal shape changes. Additionally, sand blast can be applied to non-metal products as it uses non-metallic abrasives. We also accept inquiries regarding abrasives and other related matters. Harada Iron Works Hiroshima Official Link

Does not contain silica, which causes silicosis! Can be used as disposable media.
"Steel Magic" is a product suitable for the removal of thick reinforced coatings and surface preparation from sturdy iron structures such as bridges, tanks (car washes), ships, and pipelines, where etching (surface preparation) is required to improve paint adhesion. It processes at about twice the speed of typical blast media while generating less dust, allowing for the rapid removal of stronger epoxy and urethane coatings. By adjusting the discharge pressure and abrasive size, etching treatment can also be performed. 【Features】 ■ Rapid removal of stronger epoxy and urethane coatings ■ Capable of etching treatment ■ Can be reused approximately five times at low pressure (35-80 psi) ■ Can be used as a disposable media at high pressure (100-120 psi) ■ Does not contain silica, which can cause pneumoconiosis *For more details, please refer to the PDF materials or feel free to contact us.
Resin-based abrasives for use with air blasting! The quality is uniform, with low friability and high durability! Can be reused multiple times depending on the application.
We would like to introduce "Polyextra," which we handle. It is suitable for deburring electronic components (flash burrs, dam burrs), cleaning resin products, and removing dirt and resin burrs from easily scratched soft metal products. Due to its similar hardness, it is also effective for replacing processes that used plant-based abrasives. The color may vary by lot. 【Features】 ■ Suitable as a substitute for plant-based abrasives of similar hardness ■ Can be processed with almost no damage to aluminum alloys and hard plastics ■ A thermosetting resin, commonly used for fashion buttons (unsaturated polyester resin) We offer options for dry blasting and wet blasting (liquid honing). *For more details, please refer to the PDF materials or feel free to contact us.
Resin-based abrasive material for use with air blasting! Ideal for removing thin burrs from soft metals, resin burrs, and for cleaning molds and screws of molding machines!
"Type Three" is a material commonly used for melamine tableware, which is made of thermosetting rigid plastic. It can be processed with minimal scratching on hard metals like iron, making it suitable for mold cleaning and screw cleaning of molding machines. Unlike materials such as Alundum (alumina), it causes almost no damage to the blast machine body, nozzles, hoses, or fixtures, allowing for lower maintenance costs for the equipment. We offer options for dry blasting and wet blasting (liquid honing). 【Features】 - Hard and has cutting power - Suitable for mold cleaning - Keeps equipment maintenance costs low - Allows for light cutting while processing soft metals like aluminum alloys - Options available for dry blasting and wet blasting (liquid honing) *For more details, please refer to the PDF materials or feel free to contact us.

Deburring of sealing materials in the electronic component manufacturing process.
We specialize in deburring electronic components such as capacitors, diodes, LEDs, transistors, inductors, and phototransistors, which require high-quality processing. We mainly use carefully selected domestic materials, and the quality of the abrasives is consistently uniform, allowing for stable processing without work damage. If abrasives get trapped in the terminal area, you can continue to use them by changing the material or particle size. Please give U.S.T.F.E.'s POLYMEDIA a try. *Types of burrs that can be removed (thin burrs, dam burrs, side burrs, gate burrs, resin flash, etc.) We offer options for dry blasting and wet blasting (liquid honing). Samples of abrasives are available.
![Cleaning of recesses and grooves [Blast processing example]](https://image.mono.ipros.com/public/product/image/3fa/2001070381/IPROS24957775411533102777.png?w=280&h=280)
By using air blast cleaning for depressions and grooves that cannot be completely cleaned with a brush, it is possible to efficiently clean them in a short time!
By using our Polyplus (urea resin), we can efficiently clean dirt and residues that cannot be removed by brushes stuck in grooves and recesses, without damaging the surface. If the workpiece is cast, it is possible to clean using either Polyplus (urea resin abrasive) or Type Three (melamine resin abrasive). We recommend selecting the abrasive based on the quality and surface condition you desire. Due to our unique production method, there is minimal variation between lots, allowing us to process any surface with the same quality. In particular, our long-time customers highly appreciate the "quality of the product that is evident upon use." We can provide samples, so please feel free to contact us if you have any interest.
Resin-based abrasives used in wet blasting (wet type)! Ideal for deburring electronic components and removing dirt and resin burrs from soft metals that are prone to scratching!
The US series is an abrasive developed for POLYEXTRA's wet blast (liquid honing) using unsaturated polyester resin. Due to its specific gravity of 1.15 to 1.25, which is close to the weight of water, fine particle abrasives tend to float on the water's surface. However, thanks to our manufacturing technology, the abrasives in the US series minimize floating on the water's surface and can maximize their performance as abrasives. Additionally, the US series is softer than TYPE III and POLYPLUS, but harder than nylon. It is suitable as an alternative to abrasives of similar hardness or plant-based abrasives, which can have variability in hardness and durability, requiring adjustments to blasting conditions depending on the batch. In contrast, our resin-based abrasives maintain consistent quality, have low friability, and are durable, allowing for repeated use according to specific applications. *For more details, please refer to the PDF document or feel free to contact us.
![Paint stripping of aluminum cans [Blast processing case study]](https://image.mono.ipros.com/public/product/image/437/2001100300/IPROS69087150172577350052.jpeg?w=280&h=280)
By using air blasting for paint stripping, it is possible to improve work efficiency without the need for organic solvent stripping or labor-intensive manual work with wire brushes!
The surface condition of aluminum cans after processing varies depending on the type of resin used. 1. When using our product "Polyextra," it is possible to leave a glossy finish while only stripping the surface coating. This is a polishing material made of unsaturated polyester resin. 2. When using our product "Polyplus," the surface is lightly cut, resulting in a matte finish. It is possible to retain designs such as grooves and indentations. This is a polishing material made of urea resin (urea-formaldehyde resin). 3. When using our product "Type Three," the surface becomes matte. It allows for efficient and quick cleaning. This is a polishing material made of melamine resin. All photos show processing with polishing materials of size "#60-80 (325-180μm)," and the blasting conditions are standardized. In the case of thin aluminum, such as aluminum cans, alumina or glass beads can quickly create holes, but our resin-based polishing materials do not easily create holes. However, due to the way the blasting is applied, the aluminum may expand (stretch), so it is necessary to understand the physical properties of the blasting target and set the blasting conditions accordingly.
