Sputtering Systems for Shaving Blade Coating

Standard & Customized Solutions

Advanced Process Technology Pvt. Ltd. (APT) designs and manufactures high-performance magnetron sputtering systems specifically engineered for shaving blade and razor blade coating applications. Our systems are available in standard configurations as well as fully customized platforms, optimized to meet the demanding requirements of high-throughput blade coating with excellent coating uniformity, adhesion, and repeatability.

APT sputtering systems are purpose-built for blade geometry, edge sharpness preservation, and multi-layer functional coatings, making them suitable for both R&D and industrial-scale production.

Blade-Specific System Design Philosophy

Unlike general-purpose sputtering machines, APT blade coating systems are specially designed for shaving blades, addressing critical challenges such as:

• Uniform coating on sharp cutting edges
• Controlled coating thickness at blade tip
• High adhesion without edge rounding
• Low-temperature processing to preserve blade hardness
• High batch consistency and repeatability
• Compatibility with multi-layer functional coatings

Our engineering approach ensures coating performance without compromising blade sharpness.
