{"product_id":"esar2rcsdh","title":"Slot Die Head for Roll-to-Roll Coater, ESAR2RCSDH","description":"\u003cp\u003eSlot die head is the most critical part for roll-to-roll slot die coater. The performance of the slot die head depends on how it distributes the slurry from a single point (the inlet) to a wide, uniform line (the exit). (1) \u003cstrong\u003eManifold\u003c\/strong\u003e: It is the internal cavity (usually coat-hanger or T-shaped) designed to ensure that the fluid pressure is identical across the entire width of the die. For battery slurries, a coat-hanger manifold is preferred because it prevents \"dead zones\" where NMP-based slurry could stagnate and dry out. (2) \u003cstrong\u003eDie Lips\u003c\/strong\u003e: The \"lips\" are the final exit point. They must be polished to a mirror finish (typically Ra \u0026lt; 0.0 um) and have a \"sharpness\" radius of less than 10 um. This sharpness is what allows the liquid \"bead\" to break cleanly when doing intermittent (patch) coating.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"height: 464.2px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 47.6px;\"\u003e\n\u003ctd style=\"width: 17.9856%; height: 47.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%; height: 47.6px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eESAR2RCSDH (ESA-R2RC-SDH)\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\u003eDie Material\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%;\"\u003e\n\u003cul\u003e\n\u003cli\u003eSlot die head: SUS630\u003c\/li\u003e\n\u003cli\u003eOther parts contacted with slurry: SUS304\u003c\/li\u003e\n\u003cli\u003eSealing parts: silicone, EPDM, PTFE\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 316px;\"\u003e\n\u003ctd style=\"width: 17.9856%; height: 316px;\"\u003e\u003cem\u003eCoating Head Types\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%; height: 316px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eRegular Single Layer Coating (Manifold: semi-sphere, single channel)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e         \u003cimg style=\"float: none;\" alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/ESAR2RCSDH_02_100x100.png?v=1775664057\"\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e Special Dual-Layer Coating (Manifold: semi-sphere, dual- channel)\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e           \u003cimg style=\"float: none;\" alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/ESSMR2RC_15_100x100.png?v=1775662134\"\u003e    \u003cimg height=\"84\" width=\"131\" style=\"float: none;\" alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/ESSMR2RC_16_100x100.png?v=1775662200\"\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 17.9856%;\"\u003e\u003cem\u003eInlet\/Outlet Connection\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%;\"\u003e\n\u003cul\u003e\n\u003cli\u003eInlet: φ34mm, quick connection\u003c\/li\u003e\n\u003cli\u003eVentilation: G3⁄8\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 47.6px;\"\u003e\n\u003ctd style=\"width: 17.9856%; height: 47.6px;\"\u003e\u003cem\u003eCoating Width\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%; height: 47.6px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eMax. 160 mm, 260 mm, and 360 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 53px;\"\u003e\n\u003ctd style=\"width: 17.9856%; height: 53px;\"\u003e\u003cem\u003eApplication\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%; height: 53px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eThese slot die coating heads are compatible with ESSMR2RC, ESMMR2RC, and ESLMR2RC. \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\u003eDimension\/Weight\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%;\"\u003e\n\u003cul\u003e\n\u003cli\u003eESAR2RCSDH160: L220*W135*H120mm (25 kg)\u003c\/li\u003e\n\u003cli\u003eESAR2RCSDH260: L320*W135*H120mm (38 kg)\u003c\/li\u003e\n\u003cli\u003eESAR2RCSDH360: L420*W135*H120mm (50 kg)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eReferences\u003c\/strong\u003e:\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/iopscience.iop.org\/article\/10.1088\/1757-899X\/1237\/1\/012014\/meta\"\u003eF.
