Manufacturing & Facilities

From Casting to Machining: End-to-End Aluminum Manufacturing Excellence

Conglin Aluminum has built a comprehensive industrial ecosystem that integrates alloy casting, mold manufacturing, extrusion, precision machining, and testing.

Our production system is powered by four advanced alloy casting lines and 15 extrusion presses ranging from 1,000 to 10,000 tons, capable of producing large-section aluminum profiles up to 950 mm in width, 580 mm in diameter, and 30 meters in length.

With a state-of-the-art mold design center, flexible tooling lines, and Korea SME casting technology, we develop and extrude 2xxx, 5xxx, 6xxx, and 7xxx series alloys with an annual capacity of 150,000 tons.

Every stage—from alloy formulation to precision extrusion and final inspection—is completed inhouse, ensuring full process control, stable quality, and rapid response to custom engineering needs.

Mold Manufacturing

Equipped with a mold design center and world-class flexible mold machining production lines, the company has nearly 30 years of experience in mold design and manufacturing. It independently designs and produces extrusion dies, ensuring rapid development and fast delivery.

Alloy Casting

Equipped with four first-class casting lines designed by Nippon Light Metal, the company produces up to 150,000 tons of aluminum billets annually (Series 1xxx–7xxx).

Profile Extrusion

Conglin operates 15 extrusion production lines imported from Japan and Italy, with gradient capacities of 10,000 tons, 9,000 tons, 8,000 tons, 7,000 tons, 6,000 tons, 4,400 tons, 4,000 tons, 3,000 tons, 2,700 tons, 2,000 tons, and 1,000 tons.

These comprehensive configurations cover the R&D and production of large, medium, and smallsized aluminum profiles.

The facilities are capable of producing ultra-large industrial aluminum alloy profiles with a maximum width of 950 mm, diameter of 580 mm, and length up to 30 meters.

The annual production capacity reaches 100,000 tons of industrial aluminum profiles.
