Our ultra-thin stainless steel shaving razor blades are manufactured using precision chemical etching, a highly controlled subtractive micro-fabrication process ideal for producing extremely fine, sharp, and dimensionally accurate metal components. Unlike stamping or laser cutting, chemical etching uses photo-resist and acid etchants to dissolve metal with micron-level precision while maintaining the material’s original mechanical properties.

This process allows us to create ultra-thin structures—such as 0.05mm stainless steel razor blades—with perfectly smooth, burr-free edges, consistent sharpness, and repeatable geometric accuracy.

✓ Perfect for Ultra-Thin Metals

Chemical etching does not apply mechanical force, making it ideal for:

• 0.05mm thin stainless steel

• Flexible and delicate metal foils

• Components requiring high precision with no deformation

✓ Burr-Free, Stress-Free Edges

No mechanical cutting =

• No burrs

• No microcracks

• No edge stress

• No distortion

This is critical for shaving blades where edge quality determines shaving comfort and performance.

✓ High Dimensional Accuracy

Photo-tooling ensures:

• Micron-level feature control

• Tight tolerance (±0.01mm)

• Precise and repeatable edge geometry

Ideal for mass production of blades requiring consistent quality.

✓ Sharper Edge Definition

Chemical etching allows fine control of:

• Tapered edges

• Edge angle variations

• Micro-perforation patterns

• Functional slots and notches

This results in superior blade sharpness and smoother user experience.

✓ Scalable & Cost-Efficient

• No expensive hard tooling

• Fast sample iterations

• Low-volume or high-volume production

• Perfect for new designs and rapid engineering validation
