Extrusion
20 extrusion lines, 600 to 2,000 tonnes
A wide press range lets every profile run on the right machine: small presses give fine, precise sections — LED channels, hinges, phone-case frames — while the 1,350 t and 2,000 t presses handle wide heat sinks, formwork and heavy structural sections.

Photo tour
Inside the Tangxia plant
From primary-aluminum billets to packed profiles — every area of the plant, as it runs today.
Extrusion lines
20 extrusion lines with horizontal presses from 600 to 2,000 tonnes, runout tables, cooling tables and straightening.
Raw material
Billets are cast in-house from primary aluminum — no recycled scrap — and checked before they reach the presses.
Aging
Artificial aging ovens bring extruded profiles to T5 or T6 temper, verified by hardness testing.
Die library
Customer dies are stored on numbered racks, maintained between runs and reserved for their owners' profiles.
Fabrication & warehouse
Cutting, machining and export packing — profiles leave the plant protected, bundled and labelled.
Laboratory
Composition, microstructure, hardness, tensile strength and dimensions are checked in our on-site laboratory.
