{"product_id":"erpcnpdvfsm","title":"ECS-R Nail Piercing Degassing and Vacuum Final Sealing Machine for Pouch Cells, ERPCNPDVFSM","description":"\u003cp\u003eA Nail\/Needle Piercing Degassing and Vacuum Final Sealing Machine (frequently called a Secondary Vacuum Degassing \u0026amp; Side Sealing Machine) is a specialized battery assembly unit used in pouch cell manufacturing. During initial formation cycling (the first charge-discharge cycles where additives like VC, FEC, and DTD decompose to form the Solid Electrolyte Interphase layer), significant quantities of reaction gases (CO2, CO, H2, C2H4) are released. This gas expands into a temporary extended pocket called the gas bag or gas pocket. The machine pierces this gas bag under deep vacuum to extract all formation gas and residual solvent vapors, then applies a permanent final heat-seal along the inner edge adjacent to the active electrode stack.\u003c\/p\u003e\n\u003cp\u003eThe nail piercing degassing and vacuum sealing machine normally includes the following procedures: (1) \u003cstrong\u003eCell Loading \u0026amp; Chamber Evacuation\u003c\/strong\u003e: Pouch cells (with inflated gas bags post-formation) are loaded into the vacuum chamber. The chamber seals and evacuates to a deep vacuum level (typically -90 kPa to -98 kPa \/ \u0026lt;100 Pa) to equalize internal and chamber pressure, preventing explosive pouch ruptures. (2) \u003cstrong\u003eNeedle Piercing (Nail\/Prick Degassing)\u003c\/strong\u003e: A hollow or solid stainless steel\/tungsten piercing needle (or blade fixture) extends inside the vacuum chamber to puncture the gas bag layer. Piercing under vacuum ensures that trapped SEI formation gases (CO2, CO, H2, C2H4) and volatile solvent vapors are immediately drawn into the exhaust stream without escaping into the ambient environment. (3)\u003cstrong\u003e Vacuum Extraction \u0026amp; Mechanical Squeegee (Optional)\u003c\/strong\u003e: Pneumatic or servo-driven flattening plates apply controlled uniform face pressure (0.05 MPa - 0.2 MPa) across the body of the pouch cell. This mechanical pressing squeezes out any gas bubbles trapped between the porous electrode sheets and separator layers, pushing them out through the newly pierced hole. (4) \u003cstrong\u003eFinal Thermal Impulse Sealing\u003c\/strong\u003e: While maintaining deep vacuum and face pressure, heated sealing jaws clamp down along the inner sealing line (between the active cell body and the gas bag) with regulated pressure (0.2 MPa - 0.6 MPa). Digital PID temperature control (RT - 250°C) melts the inner Polypropylene (PP) layer, forming a permanent, hermetic final seal.\u003c\/p\u003e\n\u003ctable width=\"613\" style=\"height: 882.8px; width: 109.308%;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 47.6px;\"\u003e\n\u003ctd style=\"width: 22.3022%;
