مقارنة بين CPM وD2 والكربيد لشفرات التحبيب ذات الأحمال العالية (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 […]

سكاكين تحبيب من كربيد التنجستن: دليل أفضل الممارسات

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 […]

أوقف التصاق الحبيبات: أفضل الممارسات لـ سكاكين محببات الخيوط البلاستيكية

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. […]

مواجهة تحديات AHSS: اختيار سكاكين شق الصلب للفولاذ عالي القوة المستخدم في السيارات

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. […]

أهمية صقل المرآة: كيف يتم تصنيع سكاكين الشق الدائرية لضمان طول العمر

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. […]
