Ceramic blasting media B170: The "Hidden Hero" in Apple's Metal Surface Treatment

In the modern electronics manufacturing sector, Apple has always been at the forefront of the industry with its relentless pursuit of detail and exquisite craftsmanship. The iPhone and iPad, as Apple's flagship products, are symbols of high quality.

I. Sandblasting Requirements for iPhone and iPad

Apple's pursuit of product design is not only about the ultimate appearance but also about the comprehensive refinement of texture and durability. The metal casings of the iPhone and iPad are typically made of aluminum alloy or stainless steel, which are prone to burrs, scratches, or oxidation layers during processing. To ensure the products are flawless, sandblasting is an essential process. It not only effectively removes these imperfections but also provides an ideal surface adhesion for subsequent anodizing or coating processes, ensuring the products remain as good as new over long-term use.

II. Application of B170 Ceramic Sandblasting

B170 ceramic sandblasting is a high-performance sandblasting material made of zirconium oxide. With its high hardness, low dust emission, and excellent chemical inertness, it has become the first choice for Apple's metal surface treatment. It can achieve a uniform satin finish, giving the metal surface of the iPhone and iPad a luster that avoids excessive reflection. The material's fine and uniform particles create a smooth and consistent texture on the surface after sandblasting, significantly enhancing the product's visual quality.

B170 ceramic sandblasting has been widely used in the production of iPhones and iPads. From the iPhone 4 to the current iPhone 14 series, and the metal casings and bezels of the iPad series, B170 ceramic sandblasting has been the secret weapon for Apple to enhance product quality. It not only makes the products look more refined but also enhances the wear resistance and fatigue resistance of the metal surface, ensuring that users do not have to worry about scratches or wear during daily use.

III. Advantages of Sandblasting Process

1. Enhanced Aesthetic Quality

B170 ceramic sandblasting achieves a uniform satin finish, giving the metal surface a luster that avoids excessive reflection. This fine texture not only improves the visual effect of the product but also provides a premium tactile experience for users.

2. Improved Surface Performance

The increased surface roughness after sandblasting significantly enhances the adhesion of coatings, extending the product's lifespan. This means that whether it is anodizing or other coating processes, better results can be achieved on surfaces treated with B170, ensuring the products remain in pristine condition over long-term use.

3. Environmental and Efficient

B170 ceramic sandblasting has a long service life, 15-20 times that of traditional glass beads, and can be reused multiple times, greatly reducing production costs. At the same time, the sandblasting process generates almost no dust, and its chemical inertness ensures no contamination of the metal surface, meeting Apple's strict requirements for environmental protection and sustainability.

4. Reduced Pollution

During the sandblasting process, B170 generates almost no dust and is chemically inert, ensuring no contamination of the metal surface. This not only guarantees the high quality of the products but also ensures a clean production environment and protects the health of workers.

IV. Conclusion

Ceramic sandblasting B170 plays a crucial role in the metal surface treatment of iPhones and iPads. It not only enhances the aesthetic quality of the products but also improves the wear resistance and fatigue resistance of the metal surfaces. As Apple continues to explore new materials and processes, ceramic sandblasting technology is expected to continue supporting electronics manufacturing in the future, further enhancing product quality and user experience. Just as Apple has always pursued, every detail deserves to be refined, and B170 ceramic sandblasting is the perfect embodiment of this pursuit.
