Hot and Cold Press Forming Production Line

Core Application Areas

● Fuel Cell Sector: The production line is designed for catalyst coating transfer of CCM and MEA membrane electrodes, as well as thickness-controlled forming of 5-in-1/7-in-1 components. It ensures uniform hot-press bonding between the catalyst layer and proton exchange membrane, maintaining consistent active layer thickness and interfacial bonding strength.

● Gas Diffusion Layer (GDL/Carbon Paper/Carbon Cloth) Production: The equipment precisely controls the thermal bonding process between the microporous layer and substrate, with closed-loop regulation of compression ratio and thickness tolerance—meeting stringent electrochemical and mechanical performance requirements for GDLs.

● Power Battery Thermal Management: Hot-press lamination of CCS aerogel insulation pads and edge cold-press cutting are completed in a single process. The aerogel core material fully bonds with glass fiber or polyimide encapsulation film at high temperatures, while the cold-press stage rapidly stabilizes dimensions, ensuring dimensional stability and flame-retardant properties of the insulation pads.

● Flow Battery Bipolar Plates (Graphite/Plastic Composites): Through thermal curing of conductive fillers and resin matrix, combined with cold-press shape retention, the production line consistently maintains plate warpage within ≤0.1mm/m²—significantly improving stack assembly yield rates.

● Automotive Electronics: Continuous in-line completion of multi-layer thermal lamination and rapid cooling stabilization for interior/exterior functional films (UV-resistant, anti-explosion, conductive, etc.). Achieves bubble-free, displacement-free layer bonding with optical-grade surface flatness.

● Advanced Composites: Materials such as carbon fiber prepreg and glass fiber sheets immediately enter the cold-press stage for dwell cooling after hot pressing, effectively eliminating residual stress. This significantly enhances dimensional stability and long-term service reliability of finished products.

Product Advantages

● Zero-Warpage Flatness: The cold-press stage "freezes" the hot-formed shape under pressure, achieving flatness up to ≤0.05mm/m²—meeting strict sealing requirements for precision components like membrane electrodes and bipolar plates.

● High Efficiency, Low Energy: Hot press dedicates to heating, cold press to cooling. Parallel operation cuts cycle time by 30%–50%, while recovered cold-press heat reduces overall energy consumption by over 15%.

● Precision Thickness Control: Closed-loop servo positioning and pressure regulation maintain thickness tolerance within ±0.01mm—ideal for batch production of compression-sensitive materials such as carbon paper and aerogel felt.

● Cleanliness Assurance: Dust-proof sealed design with optional hard chrome or Teflon-coated platens. Compatible with ISO Class 5 clean enclosures to meet stringent production environments for membrane electrodes and optical films.

Beyond hardware, we provide fully developed process recipe packages covering temperature curves, pressure gradients, and cooling rates.
