CPM vs D2 vs Carburo para cuchillas de peletizadora de alta carga (2026)

High‑load pelletizing punishes cutting edges with abrasive fillers, intermittent impacts, and heat. There’s no universal winner. If edge chipping is your dominant failure mode, CPM tool steels usually outperform conventional D2 and low‑binder carbides. If pure abrasive wear dominates under steady load, cemented carbide can deliver the longest life and most regrinds. Where heat and […]

Cuchillas de peletizadora de carburo de tungsteno: Guía de mejores prácticas

If abrasive-filled compounds keep chewing through your blades, you’re not alone. Between 0–50% glass fiber, talc/CaCO3 fillers, high line-speed shear, and frequent start/stop cycles, edge life collapses—and pellet quality goes with it. Upgrading to tungsten carbide pelletizer knives addresses the core failure modes while stabilizing pellets and trimming unplanned downtime across strand, die-face/underwater, and ring/centrifugal […]

Evite el pegado de pellets: Mejores prácticas para cuchillas de peletizadora de tiras

Pellet linking—pellets sticking or fusing together after cutting—wastes time, increases fines, and forces unplanned downtime. In strand pelletizing, the cut must be a clean shear on a fully solidified strand. When knives are dull or mis-set, when runout is present, or when cooling/traction aren’t matched to the polymer, you’ll see smearing, tails, and linked pellets. […]

Por qué lo barato sale caro: descifrando la economía de las cuchillas rotativas de corte premium

Verdict in 30 seconds: If you’re slitting stainless or high‑strength steels at moderate-to-high speeds—or your downtime costs run above roughly $50,000 per hour—premium Rotary Slitter Knives (HSS/PM‑HSS/Carbide, precision‑ground, coated) win on total cost of ownership. They cut scrap, stretch regrind intervals, and slash changeovers. If you’re a small shop on mild CR/HR steel with downtime […]

Superando los desafíos del AHSS: Selección de cuchillas de corte de acero para acero de alta resistencia automotriz

Automotive AHSS grades like DP, TRIP, and martensitic steels can turn a routine slit into a line-stopping headache. Burrs and micro‑chipping surge, edge ductility drops, and downstream formability (HER) suffers. This guide gives plant, process, and maintenance leaders practitioner-grade parameters—material and hardness ranges, coating choices, edge geometry targets, and clearance settings—plus a concise troubleshooting matrix. […]

La importancia del acabado espejo: cómo se fabrican las cuchillas circulares de corte para una mayor longevidad

You need a smooth surface to make accurate cuts. A mirror-polished edge on Circular Slitting Knives helps you cut better and faster. This finish stops burrs and friction that slow work. It also keeps material from sticking to the blade. Stuck material can hurt blades and make cuts less exact. Nanjing Metal Industrial makes each blade with great skill. […]

Optimización de su configuración: cómo las cuchillas de la línea de corte y los espaciadores trabajan juntos para lograr bordes perfectos

You want each slitting job to have neat, sharp edges. Slitting Line Knives and spacers work as a team. The right material and blade shape help your knives work better. You need to set the space between blades carefully. When you set it up right, you work faster and can use machines to keep the slitting process […]

La ciencia del corte: Cómo la geometría de las cuchillas rotativas de corte afecta la precisión

You use rotary slitter blades to make accurate and clean cuts. These blades are important in tough manufacturing jobs. The shape of each blade helps you get precise results. It also helps you stop mistakes from happening. Blade material, quality control, and burr reduction all change how accurate your cuts are. They also affect how smooth the finish […]
