Isostatic Laminators

From the two vessel technologies, mono-block and wire-wound, the wire-wound technology systems can be scaled up to a cylinder volume of 2000 L.

The upfront investment seems high, but is rather low compared to other machinery used in today’s battery manufacturing. Calculations with a realistic cost-model we established, put isostatic pressing in the lower cent area per KWh. The calculation model fits different parameters, the ones that show a high impact are pouch dimensions and vessel size, which can be adapted to customers preferences.

Cold Isostatic Pressing (CIP) is a wet bag compaction method, subjecting compacted powders, enclosed by a flexible rubber mold, to extreme isostatic pressure to create optimum sintering/densification conditions. The most commonly used pressure media for CIP is water at ambient temperature.

The production series of warm isostatic battery presses are able to deliver pressures up to 600 MPa, while reaching temperatures of 150 degree Celsius (pressure media can be water or oil).

CIP is commonly used to ensure a homogenous powder green bodies for optimum sintering processes for metal alloys, refractory metals, brittle magnetic and ceramics, etc.
