Full Article Structure
1. Why Carbide Blades Are Used in Knife & Scissors Production
Tungsten carbide blades keep sharpness longer than steel blades. For mass production of scissors and kitchen knives, carbide cutting blades reduce frequent sharpening downtime and stabilize cutting quality for metal, fabric and composite trimming.
2. Main Carbide Blade Types for Scissors Industry
| Blade Type | Feature | Application |
|---|---|---|
| Flat Rectangular Blade | Straight edge, easy to mount | Scissors blank trimming, slitting |
| Circular Carbide Blade | Rotary cutting, smooth edge | Continuous slitting, roll material cutting |
| Special Shaped Blade | Custom profile by drawing | Special scissors forming & notching |
3. Grade Selection for Cutting Edge
- Fine grain grade: Better edge retention, for light cutting, less impact
- Medium grain grade: Balanced toughness and wear resistance, most popular for scissors factory
- Coarser grain grade: Higher impact resistance, for heavy cutting with shock load
4. Manufacturing Process Overview
- Powder pressing → Sintering → Blank inspection → Surface grinding → Edge honing → Dimension check
- We can drill mounting holes, make chamfer and custom edge angle according to customer drawings.
5. FAQ for Scissors Blade Customization
Q1: Can you produce blades with special edge angle?
Yes, we can grind different edge angles as your cutting requirement.
Q2: What is the MOQ for custom carbide blades?
Small trial order is acceptable before mass production for knife & scissors customers.
