Laser Welded Pillow Plates Service
CipherFab offers a specialist laser welded pillow plate service — producing precision double-wall stainless steel heat transfer panels with integrated hydraulic flow channels, fabricated by laser welding two sheet metal layers at a defined spot-weld pattern and then pressure-inflating the internal cavity to form internal flow channels without machining, drilling, or mechanical assembly. The result is a fully integrated heat transfer panel — hermetically sealed, pressure-tested, and ready for installation — produced as a single welded component with no gaskets, no fittings, and no leak paths from mechanical joints. CipherFab provides instant quotes on laser welded pillow plates with DFM feedback on every uploaded file.

Design Guide: Laser Welded Pillow Plates
We have compiled our best tips into this guide to help you understand laser welded pillow plate design, how to specify weld pattern type and pitch for your target flow and heat transfer performance, sheet thickness selection relative to working pressure, inflation pressure calculation and deformation prediction, connection nozzle sizing and placement, surface treatment selection for your process fluid compatibility, and how to specify pressure test level, helium leak test requirements, and material documentation for pharmaceutical and food-grade applications.
Advantages of Laser Welded Pillow Plates
Laser welded pillow plates replace conventional plate heat exchangers, cooling jackets, and embossed panels with a single integrated, laser-welded, and hydraulically expanded component — eliminating gaskets, mechanical compression fittings, and O-ring joints that are the primary leak failure modes in traditional heat exchanger construction. The laser weld pattern defines the flow channel geometry with millimetre-precision, allowing customised flow path design — dot pattern, diamond, herringbone, or fully bespoke — to optimise turbulence, heat transfer coefficient, and pressure drop for a specific process application. Hydraulic pressure testing to 1.5× working pressure is performed on every panel before shipment — not as a sample check, but as a 100% production test — ensuring zero leak path risk before installation. CipherFab's pillow plate service covers stainless 304, 316L, and duplex 2205, in panels from 200 mm × 200 mm through 3,000 mm × 1,500 mm, with instant online pricing and DFM feedback on every upload.
