Custom Etched Metal Blade Service High Carbon Stainless Steel Razor Blades 0.02mm-1.5mm

Custom Etched Metal Blade Service High Carbon Stainless Steel Razor Blades 0.02mm-1.5mm

Xinhaisen etches metal blades and cutting strips as a contract service. The blade outline, edge profile and the hole or slot pattern in the blade body are formed by photochemical etching in one pass from the artwork, so the edge is produced by controlled metal removal rather than by grinding or shearing.

Because the process uses no cutting force and no local heat, the metal keeps its grain structure, the edge carries no grinding burr and no recast rim, and the blade stays flat along its length. Hardening, coating and honing are added afterwards where the blade design calls for them.

Blade Types We Etch

• Cartridge and safety razor blades, trimmer and grooming blades
• Surgical, dermatological and biopsy blades
• Slitting, trimming and converting blades on strip form
• Doctor blades, scraper blades and stripping blades
• Foil and film cutting blades, micro blades for instruments
• Blade bodies with lubrication holes, locating slots and grip patterns

Blade Design Points Reviewed With You

Edge angle is reviewed against material thickness, because a fine edge on 0.05mm foil and a durable edge on 0.8mm strip call for different profiles. Sharp internal corners in the blade body are replaced by a small radius to keep the etch clean at the corner, and blade bodies are held with connecting tabs during etching so a thin blade does not curl before it reaches your assembly line. Where the edge is honed or coated after etching, that step is defined on the drawing so the final edge geometry is measured on the finished blade rather than on the etched blank.

From Drawing To Delivery

1. Drawing review. We check edge profile, material, thickness and tolerance, review the body features and the secondary steps, and reply with feasibility comments and a quotation.

2. Phototool and first article. Artwork is converted to a phototool and first article blades are etched for your cutting test, with material certificate and inspection data.

3. Approval and production. After the first article is approved the process parameters are fixed for the run and etching values are held under process control.

4. Inspection and packing. Blades are checked against the drawing, inspected visually for edge integrity, and packed so the edges are protected in transit.

Quality System

Incoming material is inspected before production and finished blades are inspected before shipment, so the quality of each batch is assured.

Applications

Shaving and grooming products, medical and laboratory devices, packaging, textile and converting equipment, slitting and trimming lines, sensor and instrument components.

Frequently Asked Questions

Which material suits an etched blade?
Stainless steel is used where corrosion resistance matters, and high carbon steel is chosen where hardness after heat treatment drives the cutting life. The final grade follows the cutting application and the edge profile of your drawing.

How is the cutting edge produced?
The edge profile is defined in the artwork and formed by controlled chemical removal, so no grinding burr or shear burr is left on the edge. Where the design calls for honing or coating, that step is added after etching and measured on the finished blade.

Can blades be supplied joined on a strip?
Yes. Blades can be delivered singulated, on strip, or held on a carrier frame with connecting tabs, which suits automated feeding on the assembly line.

Can holes and slots be etched in the blade body?
Yes. Lubrication holes, slots, locating features and grip patterns are etched in the same operation as the outline, so no secondary punching step is needed.

How is the schedule agreed?
Each blade is custom, so the schedule depends on material, edge profile, secondary processing, quantity and the first article approval step. Timing is confirmed with the quotation and again when the first article is approved.
