Precision Etched Metal Blades Custom Chemical Etching Service

Precision Chemical Etched Razor Blades Manufacturer

Xinhaisen specializes in manufacturing custom etched razor blades using advanced photo chemical etching technology. Compared with conventional stamping or laser cutting, chemical etching produces burr-free edges, highly accurate geometries, and stress-free components without affecting material properties.

Precision Etched Blades are manufactured using advanced Photo Chemical Machining (PCM), enabling burr-free edges, intricate geometries and extremely fine features that cannot be achieved economically by traditional stamping or laser cutting.

Xinhaisen manufactures custom etched metal blades using precision photo chemical etching technology. Unlike conventional machining or stamping, chemical etching uses a controlled photochemical process to create complex blade profiles from thin metal sheets without mechanical cutting forces.

Manufacturing Process

• Material Selection & Cleaning: High-carbon steel, stainless steel, or specialized alloys are selected and meticulously cleaned.

• Photoresist Lamination: A light-sensitive polymer film is applied to the metal sheet.

• Precision Patterning: The blade design is exposed onto the resist using high-resolution digital tooling.

• Controlled Etching: The exposed metal areas are etched away with a controlled chemical solution, forming the exact blade profile and edge.

• Stripping & Cleaning: The photoresist is removed, and the blades undergo thorough cleaning.

• Secondary Processing: This includes optional hardening, coating, and final sharpening/honing.

• 100% Quality Inspection: Each batch is inspected for edge integrity, dimensional accuracy, and surface finish.

Razor Blades Features

• Unmatched Sharpness: Etching produces a consistently thin, clean, and acute cutting edge right from the substrate, enhancing initial sharpness.

• Burr-Free Edges: The non-contact, stress-free etching process eliminates mechanical burrs common in stamping or grinding, ensuring smooth performance.

• Complex Geometry: Ability to create intricate hole patterns (for lubrication/cleaning), specialized edge profiles, and textured grips with high precision.

• Material Integrity: No heat or mechanical force is applied during shaping, preserving the grain structure and inherent properties of the metal.

• High Consistency: Excellent batch-to-batch repeatability with tolerances as tight as ±0.01mm.

• Customizable: Full flexibility in design, material, hole patterns, coatings, and packaging.Ultra-Fine Precision

FAQ

Q: How does etched blade sharpness compare to traditionally ground blades?
A: Etching creates a fundamentally sharp edge from the material itself. While both methods can achieve high sharpness, etching offers superior consistency and eliminates microscopic burrs from mechanical deformation, often resulting in a smoother initial shave. Final honing can be applied post-etch for ultimate sharpness.

Q: Can you create blades with lubrication strips or specific hole patterns?
A: Absolutely. Photochemical etching is ideal for integrating precise micro-holes, slots, or complex patterns into the blade design for functions like lubrication delivery, hair clearance, or weight reduction.

Q: What are the benefits of different coatings?
A: Coatings enhance performance. PTFE reduces friction for a smoother glide. DLC (Diamond-Like Carbon) significantly increases hardness, corrosion resistance, and longevity, providing an exceptionally durable edge.

Q: What is your minimum order quantity ?
A: We are flexible to support both prototyping/low-volume needs and mass production. Please contact us with your specific project details.

Q: Can you work with our custom alloy or design?
A: Yes. We have extensive experience processing various metals. Our engineering team can collaborate on optimizing your design for the etching process and material selection.
