This article introduces the engineering advantages of 920mm super large aluminum extrusion dies and multi‑hole moulds for high‑volume aluminum profile production. As a specialized multi‑hole mould manufacturer with over 17 years of experience, we explain how large‑format dies (up to 920mm) combined with multi‑cavity designs significantly increase extrusion output, reduce energy consumption, and lower cost per part. The article covers key technical parameters (H13/SKD61 steel, vacuum heat treatment, CMM inspection), typical applications (EV battery trays, LED frames, large heat sinks, mass transit profiles), and a case study of a 4‑hole die for automotive structural parts. Quality certifications (ISO 9001) and optional try‑out services on 3600T–5000T presses are also highlighted. For manufacturers seeking to scale up production with super wide aluminum tooling, this technical overview demonstrates why precision‑engineered multi‑hole dies are a proven investment.

IntroductionIn the demanding world of industrial aluminum profiles, the ability to produce large-scale, complex, and high-precision extrusions separates leading manufacturers from the rest. At the forefront of this capability is the 920mm super-large aluminum extrusion die—specifically engineered fo
