Precision Micro stands as the global leader in manufacturing flow plates for printed circuit heat exchangers (PCHEs), offering unmatched volume capacity and exceptional channel accuracy.
A printed circuit heat exchanger combines chemical etching and diffusion bonding technologies. Flow channels are chemically etched onto metal plates, which are then stacked and solid-state joined through diffusion bonding to form a single block.
Since the 1990s, Precision Micro has been a pioneer in PCHE manufacturing. Our market-leading chemical etching service provides volume versatility, catering to fast, cost-effective prototypes to high volume production. Our production etching plant is capable of supplying etched flow plates up to 1500mm x 600mm in size and thicknesses up to 2.5mm.
Our chemical etching process is compatible with a wide range of metal types and grades. While 316-grade stainless steel is commonly specified for plate and printed circuit heat exchanger plates, we can also work with lightweight, corrosion-resistant metals like aerospace grade aluminium.
