Gefahren beim Schreddern von Lithium-Ionen-Batterien: Steuerung durch Langsamläufer-Scheren, Auslegung von Inertgasatmosphären und HF-Behandlung

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), […]

DLC- vs. PTFE-Beschichtungen für Längsteilmesser: Leitfaden zur Auswahl nach Verschleiß- und Anhaftungskriterien

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, […]

OEE- und Gewinnsteigerungen durch Reduzierung der Coil-Wechselhäufigkeit: Verfügbarkeitsmodell, Praxisbeispiele und Pilotdaten

Quick Answer: Reducing coil change frequency improves OEE primarily by cutting planned downtime—a direct hit to Availability. Secondary gains appear in Performance (fewer ramp-up periods after restarts) and Quality (fewer splice-related defect windows). The effect is quantifiable with four inputs: strip consumption rate, coil length, changeover time per stop, and scrap generated per change. In a […]

Sorte, Design und Steuerung von Wolframkarbid-Messern für maximale Unterwassergranulator-Laufzeit

Quick answer: Stable die-face cutting on underwater pelletizer lines depends on four variables working together: carbide grade (HRA 88–92 for most WC–Co inserts), edge geometry (controlled radius, not just “sharp”), contact pressure management (engage → trim, not pressure-chase), and water-loop stability (40–60°C, filtered, degassed). Changing inserts without addressing die-face condition or cutter-head balance is the most […]

Rotationsplan und Nachschliffkriterien für 4-seitige Wendemesser: Messdatenbasierte SOP für Tafelscheren

If you run a guillotine shear on mixed carbon steel, stainless, and high-strength grades, you already know the failure pattern: burrs creep up, operators “chase” the gap, and downtime turns reactive. This article defines a measurement-based protocol for 4-edge reversible blades—when to rotate, when to regrind, and what to log so the process is third-party […]

ROI von Kreismessern zum Längsteilen (Slitter): TCO-Modell & Standzeitanalyse von PM-HSS vs. Werkzeugstahl

Rotary slitter knives look like a small line item until you model what they touch: changeovers, scrap, burr rework, and whether your line can hold tolerance across an entire coil. This guide is written for process, equipment, production, and purchasing leaders at coil slitting operations who need a defensible way to compare options, especially when […]

Toleranzkettung bei Mehrwellenmessern: GD&T-Kontrollen, selektive Passung von Distanzringen und TIR-Überprüfung nach der Montage

Key takeaways: In multi-shaft shredders, small errors in blade thickness, spacer thickness, face flatness, squareness, and bore/shaft geometry don’t stay small. They add up into shaft tilt and total indicated runout (TIR), which shows up as gap drift, uneven load, vibration, and shorter knife life. This guide gives practical GD&T targets, selective-fit spacer strategy, assembly/QA […]

Federbelastetes System für das Scherschnitt-Längsschneiden mit Nullspiel: Kontrolle von Überlappung, Anstellwinkel und Vorspannung

If you’re running thin films or nonwovens at speed, shear slitting stops being “just knife setup” and starts behaving like a stability problem: tiny runout, inconsistent contact, or drifting knifeholder air preload pressure becomes edge defects and downtime. This guide is written in the shop-floor practical approach Maxtor Metal uses when supporting customers on film […]

Validierung von 440C Ersatzmessern für Urschel Würfelschneider bei HRC 56–58: Wärmebehandlungsfenster, RA-Kontrolle und QA-Protokoll

Urschel-style dicer heads operate under demanding cyclic loading: blade bands contact product at high frequency, with impact severity varying significantly between soft fresh produce and hard frozen product (IQF frozen vegetables and root crops can present surface hardness comparable to hardened wood). Cut-size capability and blade life are directly coupled—a band that chips on the […]

Technische Qualifizierung von Messersätzen für die petrochemische Großproduktion

Quick answer: A water-ring pelletizer knife block is qualified for high-volume production by verifying four things: runout/TIR at functional datums (typically ≤0.03–0.04 mm), balance grade per ISO 21940 (G6.3 baseline, tightening to G2.5 at higher speeds), vibration acceptance per ISO 20816 (often ≤2.8 mm/s RMS), and full material traceability via EN 10204 3.1/3.2 certificates linked to […]
