Application Cases
Chemical Fiber/Non-Woven Knives
Fabric Cutting Knives | Designed for Chemical Fiber Cutting & Non-Woven Fabric Industries
Material and Processing
Carbide: High hardness （HRA90 above)
Diverse cutting edge designs: Polygonal cutting edges, such as hexagons, octagons, and dodecagons, are employed; alternating cutting points distribute force.
CNC grinding + edge passivation + mirror polishing: Reduce cutting friction and prevent fiber stringing and burrs.
Features
Stable cutting quality: Fiber cross-section burr rate ≤ 0.5%
Long knife life: Carbide cutters last 2–3 times longer than ordinary high-speed steel cutters. Lower costs: Reduce annual knife changes by 40%.
Material adaptation wide: cement bag, woven bag, textile belt and so on.
Wide material compatibility: Higher assembly precision: Blade parallelism ≤ 0.003mm.

Why Shengong?
Q: Our equipment model is unique. Can you guarantee compatibility?
A: We have a database of over 200 knife designs, covering common imported and domestic textile equipment (such as German, Japanese models). We can precisely customize according to the customer's mounting hole drawings, with tolerances within ±0.01mm, ensuring immediate operation without on-site adjustments.
Q: Is knives life guaranteed?
A: Every batch of knives undergoes 100% microscopic inspection and wear resistance testing. We guarantee a lifespan of at least 1.5 times the industry average under specified materials and operating conditions.
Q: What if I want to optimize knife performance during subsequent use?
A: Shengong offers customized optimization services. We can adjust the cutting edge angle and coating type based on the characteristics of your textile material (such as polyester, aramid, and carbon fiber). We also offer small batch proofing.
