Blade Production Process

Stamping

• Raw Material Inspection: Steel strips are inspected for hardness and dimensions.
• Mold Installation: Molds are installed based on production orders.
• Stamping and Forming: After equipment adjustment, products are stamped and formed.
• Dimension Verification: Formed products are measured against customer drawings; production continues only if dimensions meet specifications.

Heat Treatment – Quenching

High-Temperature Furnaces: Products pass through eight furnaces (850/950/1000/1030/1060/1085/1085/900°C) for preheating, quenching, grain transformation, and shaping to enhance lightness, hardness, and wear resistance.

Deep Cooling: After quenching at 1100°C, blades undergo deep cooling at -85°C to improve durability.

Tempering: Performed at 200-400°C to eliminate residual stress and increase toughness.

Hardness Inspection: Unquenched steel strip hardness is HV 280-330; post-quenching hardness is HV 700-780. Qualified products proceed. Hourly capacity: 10,000 pieces.

Logo Production Process

• Printing Plate Installation: Different logo printing plates are installed based on order requirements.
• Plate Lifespan: Each printing plate lasts 400,000-500,000 uses.
• Minimum Order Quantity: 100,000 pieces for printing.
• Hourly Capacity: 15,000 pieces.

Blade Grinding Process

• Grinding Stages: Eight grinding wheels perform rough, fine, and precision grinding to sharpen blades. Hourly capacity: 25,000 pieces.
• Polishing: Removes burrs and rough edges from the sharpening process.
• Blade Cutting: Blades are cut into individual pieces.
• Edge Inspection: Blade edges are inspected every half hour to ensure quality.

Blade Coating Process

• Drying: Blades are dried at 160°C to remove surface impurities and moisture.
• Chromium Plating: Applied via splash method to enhance hardness, durability, and corrosion resistance.
• Teflon Spraying: Reduces friction for smoother edges; pre-spraying sharpness is above 30N.
• Sintering: Performed at approximately 400°C for 50 minutes to ensure Teflon adhesion.
• Edge and Coating Inspection: High-magnification microscope checks edge smoothness and coating condition.
• Sharpness Testing: Cutting instrument used for batch sampling; blades exceeding 16N are unqualified.

Note: Industrial blades skip coating and proceed to oiling and packaging after grinding.

Oiling Process

• Immersion: Blades are immersed in anti-rust oil for 15 minutes to form a protective film.
• Oil Types: Different types and viscosities are used based on customer needs.
• Oil Categories: Food-grade and industrial-grade anti-rust oils are available.

Blade Packaging Process

Wrapping and Boxing

• Wrapping: Blades are wrapped in wax paper and outer paper.
• Small Box Packing: Blades are packed into small boxes.
• Large Box Packing: Small boxes are manually packed into larger boxes.
• Sealing: Boxes are sealed using a film sealing machine.
• Inspection and Storage: Qualified products are inspected, stamped, and stored.

Netting Blade Packaging Process

• Netting Workshop: After oiling, blades enter the automatic netting workshop.
• Mesh Material: 304 stainless steel mesh is used.
• Welding: Automatic welding equipment attaches mesh tightly to blades.
• Tray Arrangement: Welded products are arranged in trays as semi-finished products.
• Packaging and Storage: Products are wrapped with anti-rust paper and bubble bags, inspected, and stored.

XIRUI Blade Quality Inspection

Quality Grade Classification

• Grade A: For major brands (e.g., Schick, P&G) with stricter quality standards.
• Grade B: Standard production quality.
• Grade C: For low-end clients, focusing on cost reduction through materials, packaging, and processes.

Appearance Inspection

Inspection Levels:

• Grade A and B: Level II (appearance)
• Grade C: Level I (appearance)
• Distance: 30 cm

Time:

• Grade A and B: 3-5 seconds
• Grade C: 2-3 seconds
• Light Source: Natural light or 40W incandescent light
• Angle: Inspection surface at 45° to horizontal, rotated 15° up, down, left, and right
• Inspector Vision: 1.0 or above (including corrected vision)

Note: Avoid reflective conditions

Appearance Areas:

• A Side: Primary visible side during use
• B Side: Less visible sides (e.g., back, sides)
• C Side: Invisible sides (e.g., bottom)

Customer Questions and Answers

Sharpness Concerns

Recommendation: For clients prioritizing sharpness, recommend the 74M1 model, comparable to Dorco quality but more affordable.

Minimum Order Quantity

• Standard MOQ: Custom orders typically require 500,000 pieces.
• Flexibility: 200,000-500,000 pieces acceptable based on demand.
• Small Orders: Minimum of 100,000 pieces possible for potential clients.

Blade Usage Frequency

Variability: Usage varies by individual beard characteristics; exact frequency cannot be specified.

Material Introduction for Custom Orders

Assessment: Evaluate client’s sales region and channels before recommending materials.

Material Options:

• 4cr13: For developing regions (e.g., Middle East, Southeast Asia); lower smoothness and experience.
• 6cr13: Best value; widely accepted with good durability and sharpness.
• Sandvik (13cr26): Premium material for high-end brands; best performance but more expensive.

Warehousing

Qualified products are inspected, stamped, and stored after passing all quality checks.
