Acier à outils D2 vs SKD11 pour lames de cisailles : microstructure des carbures, analyse des modes de défaillance et cadre de sélection des nuances

Quick Answer: D2 and SKD11 are compositionally near-identical high-carbon, high-chromium cold-work tool steels, but D2’s higher vanadium content (0.50–1.10%) delivers stronger abrasive wear resistance for clean, high-volume sub-6mm cutting, while SKD11’s finer carbide structure provides better impact toughness for stainless steel, variable feed, or chipping-prone operations. The decision turns on your dominant failure mode—wear or chipping—not […]

Réduction des bavures de slitage : Matrice des causes racines, plages de réglage et protocole d'inspection

Slitting burr reduction is one of those “small edge” problems that becomes a big cost problem fast: burr drives customer complaints, creates downstream forming issues, and quietly shortens knife life. This handbook is compiled by Jerry Chu, Technical Support Specialist at Maxtor Metal, drawing on 10+ years of field troubleshooting experience across coil slitting lines processing carbon […]

Éliminer les refus en bandes longues pour l'efficacité du traitement des CSR/SRF : Géométrie des couteaux, OAR de la grille et contrôle du jeu de coupe

Long-strip “rejects” are a hidden tax in RDF/SRF production. They don’t just fail a sieve-based spec—they drive recirculation load, increase wrap risk, and quietly push kWh/t up while pulling throughput down. This article lays out the engineering moves to engineer out long strips and consistently hit ≤50 mm at ≥98% passing (P98) on screen-limited sizing […]

Supprimer les coupes en serpentin dans le découpage de film : Checklist système pour lame, tension, alignement et air

Snake cuts (also called slit-line wander or drift) are what you see when a slit edge won’t hold a straight, repeatable path: lanes “walk,” oscillate, or gradually shift so the wound roll layers are no longer centered. Treat it like a stability problem across the slit-and-wind system—not a single-parameter defect. This checklist reflects the way […]

Lecture du CPT de l'acier pour outils pour couteaux pour feuillards : Une checklist AQ pratique pour la chimie, la dureté et la traçabilité

Quick Answer: To read a tool steel MTC for strip blades, start at the header — confirm EN 10204 3.1 certificate type, supplier identity, steel grade, and heat number. Then cross-check the chemistry table against your PO/spec (using ASTM A681 or ISO 4957 as the reference standard). Verify hardness uniformity with a 9-point map (head/mid/tail […]

Collage des couteaux de granulation sous eau TPU : choix des revêtements DLC vs PTFE et fenêtres d'utilisation.

Quick answer: Knife gumming in TPU underwater pelletizing is a system problem, not just a coating problem. The fastest fix is to address the mechanism first (restore cutting-plane stability and quench consistency), then select coatings: DLC on cutting-edge faces for hardness and low friction, PTFE on low-wear non-edge faces for adhesion reduction. Running DLC without fixing […]

Couteaux de cisaillement à insert carbure de tungstène pour lignes AHSS : Modèle ROI, protocole de rectification et tests pilotes.

Quick Answer: Tungsten carbide inlaid shear blades typically deliver 2–3.5× the edge life of D2 blades on AHSS lines, with ROI driven primarily by fewer changeover events and reduced edge-instability scrap—not blade price alone. Clearance control and consistent regrind geometry restoration are the two variables that most determine whether that life multiplier holds in production. […]

Entretoises de refendage de précision et anneaux en caoutchouc : Rigidité de l'empilage, contrôle du jeu et du TIR

What readers will gain: tolerances, setup, verification, and ROI logging: concrete specs to ask for, checks to run before you clamp, and what to track so “better tooling” turns into measurable uptime. High-speed coil slitting doesn’t usually fail because the knives are “bad.” It fails because the clearance you thought you had is not the clearance the […]

Risques de broyage des batteries lithium-ion : Contrôles de cisaillement à basse vitesse, conception d'atmosphère inerte et traitement du HF

Lithium-ion battery (LIB) size reduction is one of those operations where the “mechanical” and “chemical” worlds collide in the worst way: high stored electrical energy, flammable electrolyte vapors, conductive dust, and corrosive off-gases. This guide focuses on a safety-by-design approach that many facilities are converging on: low-speed, counter-rotating shear in a controlled atmosphere (often inerted, sometimes submerged), […]

Guide de Sélection des Revêtements DLC vs PTFE pour Lames de Refendage : Usure vs Transfert de Matière

Slitting performance rarely fails for a single reason. It fails at the interfaces: blade-to-web friction, adhesive transfer, edge micro-chipping, and the heat that builds when any of those drift out of control. This guide is written for process engineers, maintenance teams, and technical buyers selecting or qualifying coated circular slitting knives for film, foil, paper, […]
