NEW ENERGY

In the new energy industry, particularly in the fields of batteries, energy storage systems, and photovoltaic components, core parts—such as electrodes, separators, gaskets, and flexible circuits—require highly precise cutting, forming, and punching processes. Rotary die cutting machines are the key equipment that performs these “precision cutting surgeries.”

Lithium Battery Manufacturing (Critical Application Area)

· Electrode slitting           · Separator cutting

· Sealing gaskets (top cover/side plate insulation pads)

· Separator cutting           · EV conductive/thermal adhesives

In the production of  EV power batteries and energy storage batteries, rotary die cutting machines handle multiple key processes, including high-precision cutting of lithium battery electrodes and forming of separators.

Photovoltaic (PV) Manufacturing

– Flexible solar cells: Precision rotary die cutting of conductive substrates and encapsulation materials in thin-film solar cells.
– Conductive grids and circuits: Rotary die cutting of conductive elements within PV modules, ensuring high accuracy and consistency.
-Sealing and insulation materials: Rotary die cutting of gaskets and insulation components for PV backplanes and module frames.

Electric Vehicle (EV) Components

– Onboard flexible circuits: Precision rotary die cutting of flexible printed circuits (FPC) used in battery management systems, infotainment displays, and other onboard electronics.
– Acoustic and thermal insulation materials: Rotary die cutting of lightweight, high-performance insulation materials applied throughout the EV for noise reduction and thermal management.

FUEL CELL MEA

In fuel cell manufacturing, MEA materials are fragile and high in value, making waste reduction and process efficiency critical. HOACO specializes in precision converting solutions that ensure stable, efficient processing while protecting material integrity and minimizing scrap.

HIGH-ACCURACY ROTARY DIE CUTTING AND LAMINATING SOLUTIONS

As a core component of PEM fuel cells, the Membrane Electrode Assembly (MEA) requires extremely accurate and repeatable downstream processing. HOACO rotary die cutting and laminating machines are designed for high-precision, high-efficiency MEA converting and assembly, supporting cutting, laminating, layer alignment, and continuous production of all typical MEA layers to achieve consistent quality and optimized material utilization.

RotoMEA3: CCM by Decal Transfer

Converts two rolls of single-side-coated PTFE/PEM into a single roll of double-side-coated PEM (CCM) by heat-assisted decal transfer and lamination. Decal transfer temperature and duration can be accurately controlled to achieve optimal transfer result.

RotoMEA5: Subgasket Attachment

Cutting and laminating top/bottom sub-gasket layers to MEA3 to produce MEA5, RotoMEA5 18-stations model can add double-layer gaskets (top and bottom), while its 26-station counterpart model can attach 4-layers (top2 and bottom 2)- all in a single pass.

RotoMEA7: GDL Attachment

RotoMEA7 attaches top and bottom GDL layers to produce the final MEA assembly in sheets. Heat rollers are used when necessary to trigger heat-activated adhesive on GDL and improve lamination result.
