Hau Chang Enterprise aluminum forging factory in Lukang, Changhua, Taiwan

Forge to Microstructure

Aluminum forging in Taiwan, verified down to the grain

Hau Chang Enterprise is an ISO 9001:2015 certified aluminum forging manufacturer in Lukang, Taiwan. Forging, Heat treatment, CNC Machining, Sandblasting, Anodizing, Laser marking and Inspection are all done in one factory.

We look further into the part than the drawing asks for. A new job starts with forming simulation, so die design is settled before tooling is cut. A forging isn't finished when it fills the die. It's finished when we know its grain structure and strength.

Hau Chang at ALUMINIUM 2026, Düsseldorf
Meet Hau Chang at ALUMINIUM 2026, Messe Düsseldorf, 6 to 8 October, Hall [5] Booth [5A21]. Bring a drawing and our engineers will review it on the spot.
How a Custom Aluminum Forging Is Developed: From First Drawing to Verified Part
The four stages Hau Chang takes a forged aluminum part through: development review, process planning, production under one roof, and verification on request.
DFM at the Part Development Stage: What Changes When the Manufacturer Is Brought In Early
DFM happens while the part is still being designed. What a forging supplier feeds back when brought in early, and why it cuts sample-stage problems.
Verifying Aluminum Alloy Composition: OES vs Conductivity Meter
A conductivity meter cannot separate 6061 from 6066 after T6. OES gives the full composition in minutes. What each tool can and cannot tell you.
In-House T6 Heat Treatment for Forged 6061: Cycle, Control and Why It Stays In-House
The T6 cycle for forged 6061: solution treatment, quench within seconds, aging, and hardness checked on every load. Why the quench decides the strength.
Grain Structure in Forged Aluminum: What a Metallographic Section Shows
Grain flow is why a forging outperforms bar stock. How we section, etch and image forged aluminum to confirm grain size and flow at the loaded section.
