Plate tooling & forming
PANSTAR has in-house mould design and machining capabilities, supported by dedicated plate presses. Tooling defines the corrugation and edge geometry before the plates become a welded core.
Built around the welded block.

BLOCK HEAT EXCHANGER MANUFACTURING
From the workshop
to your process.
HEXCBLOC is manufactured by Yangzhou Panstar Heat Exchanger Equipment Co., Ltd. The production photographs show block exchangers, welded plate packs and the equipment behind their manufacture.
MANUFACTURING BASE
Tooling, welding and development
in one manufacturing organization.
The Yangzhou site combines plate tooling, pressing and welding capabilities. PANSTAR also reports an in-house thermal test facility for product development.

MANUFACTURING CAPABILITIES
The work behind the welded block.
Automated welding equipment
Laser-welding lines support welded heat exchanger production. Controlled positioning brings the plate edges together for repeatable welding along the channel boundaries.
Welding the plate pack
Adjacent plates are joined along alternating edge pairs to create two separate circuits. The narrow welded edges leave the formed passages open for flow.
Block assembly
The welded core is enclosed by the frame and bolted side panels. Connections and internal flow arrangements are configured for the selected duty and installation.
INSIDE THE CORE
Real plates. Open channels.
Close-up production photographs show the formed plate surfaces and the channel openings of a welded core. Removable side panels provide access to the channel groups for inspection and cleaning.
REAL WORKSHOP RECORD
From plate forming to shipment.
These production photographs follow real manufacturing, inspection and delivery stages—not just the finished equipment.
Plate pressing equipment
Dedicated presses and tooling form the plate geometry used in the welded heat-transfer core.
Formed plates prepared for production
Plate sections are organized by size and project before the welded core is built.
Welded plate packs in the workshop
Completed plate packs at different sizes show the core geometry before final enclosure.
Machined side panels and frame parts
Panels, rails and support parts are prepared together for project assembly.
Support components before assembly
Machined support components are checked before they are fitted to the exchanger frame.
Pre-assembly and fit-up
Side panels, studs and connections are fitted and checked before final assembly.
Leak testing before release
Completed units are connected to test equipment so pressure integrity can be checked before shipment.
Finished replacement unit
A completed welded plate-and-block heat exchanger configured as a replacement for an installed GEA unit. Final dimensions and connections are confirmed project by project.
Loading for delivery
Large units are lifted into the shipping container using the workshop crane and a controlled rigging plan.
Heavy lift for a CP120 replacement project
A packaged large-format unit is lifted under controlled supervision before transport.
