{"product_id":"eslecpchrp","title":"ECS-SL Pressure-Controlled Hot Rolling Press (W=300mm, 30T, 150°C) for Electrode Calendering, ESLECPCHRP","description":"\u003cp\u003eFor high-precision electrode calendering, transitioning from simple gap-control (setting the distance between rollers) to pressure-control is the key to achieving consistent energy density and ionic conductivity. In a pressure-controlled system, the machine uses hydraulic or servo-actuators to apply a specific, measurable force (typically in metric tons) regardless of slight variations in the initial coating thickness.\u003c\/p\u003e\n\u003cp\u003eWhen using a pressure-control press, your goal is to optimize the Packing Density (PD) = m\/(A*t). Where m is the mass of active material, A is the area, and t is the post-calendering thickness. (1) \u003cstrong\u003e10% Rule\u003c\/strong\u003e: For most lithium-ion cathodes (NMC\/LFP), aim for a thickness reduction of approximately 10–20% per pass. Attempting more can cause \"spring-back\" or delamination. (2) \u003cstrong\u003eThermal Softening\u003c\/strong\u003e: Calendering at 60-100 °C reduces the yield strength of the PVDF binder, allowing for higher density at lower pressures and reducing the risk of foil cracking. (3) \u003cstrong\u003eLinear Pressure\u003c\/strong\u003e: In production, pressure is often reported as N\/mm (force divided by the width of the electrode). Lab machines that report total \"Tons\" should be converted to linear pressure for academic reporting.\u003c\/p\u003e\n\u003ctable style=\"height: 201.2px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 17.9856%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%; height: 35.6px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eESLECPCHRP (ESL-EC-PCHRP)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 17.9856%;\"\u003e\u003cem\u003ePower\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%;\"\u003e\n\u003cul\u003e\n\u003cli\u003eAC220V±10%, three-phases, 50\/60Hz, 8000 W \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 17.9856%;\"\u003e\u003cem\u003eHot Roller\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%;\"\u003e\n\u003cul\u003e\n\u003cli\u003eΦ196 x 320 mm (effective width for hot rolling: 300 mm)\u003c\/li\u003e\n\u003cli\u003e9Cr3Mo, surface coated with chromium layer with a thickness of \u0026gt;0.08mm\u003c\/li\u003e\n\u003cli\u003eHRC65~70, hardness layer thickness ≥15mm\u003c\/li\u003e\n\u003cli\u003e1.5KW AC frequency conversion motor\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 17.9856%;\"\u003e\u003cem\u003eHydraulic Pressure\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%;\"\u003e\n\u003cul\u003e\n\u003cli\u003eMax. 30T, adjustable in HMI touch screen\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 17.9856%;\"\u003e\u003cem\u003eRolling Temperature\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%;\"\u003e\n\u003cul\u003e\n\u003cli\u003eMax. 150 \u003cspan\u003e°C (IR heating tubes)\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eThese IR heating tubes are easily installed and replaced.\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cspan\u003e          \u003c\/span\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/ESLECPCHRP_03_100x100.png?v=1775836717\" alt=\"\" style=\"margin-bottom: 16px; float: none;\"\u003e     \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/ESLECPCHRP_04_100x100.png?v=1775836894\" alt=\"\" style=\"float: none;\"\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 17.9856%;\"\u003e\u003cem\u003eCalendering Speed\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%;\"\u003e\n\u003cul\u003e\n\u003cli\u003e0.5-4.8 m\/min, digital display, adjustable\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 17.9856%;\"\u003e\u003cem\u003eCalendering Gap\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%;\"\u003e\n\u003cul\u003e\n\u003cli\u003e0-3 mm, manually adjustable\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 17.9856%;\"\u003e\u003cem\u003eCalendering Effect\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%;\"\u003e\n\u003cul\u003e\n\u003cli\u003e± 3μm (Only if the uniformity of the sample is ≤ ±2μm)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 17.9856%;\"\u003e\u003cem\u003eRoll-to-Roll Integration (\u003cspan style=\"color: rgb(255, 42, 0);\"\u003eOptional\u003c\/span\u003e)\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%;\"\u003e\n\u003cul\u003e\n\u003cli\u003eA roll-to-roll unit can be integrated with the hot rolling press for electrode roll calendering \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv style=\"text-align: start;\"\u003e        \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/ESLECPCHHRP_05_160x160.png?v=1775837521\" style=\"margin-bottom: 16px; float: none;\"\u003e      \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/ESLECPCHRP_02_100x100.png?v=1775796965\" alt=\"\" style=\"float: none;\"\u003e\n\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 17.9856%;\"\u003e\u003cem\u003eNote\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%;\"\u003e\n\u003cdiv style=\"text-align: left;\"\u003e\n\u003cul\u003e\n\u003cli\u003eEach time the reduced thickness is 20%-25%.
