Aluminium extrusion molding is a cornerstone of modern structural engineering. By pushing raw aluminum alloy billets through a custom-designed die profile, we manufacture lightweight, high-strength structural profiles that outperform traditional steel in weight-to-strength ratios, corrosion resistance, and modular flexibility.
At Chengdu E&I Aluminum Industry Co., Ltd., we utilize advanced metallurgy techniques in partnership with the National Institute of Nonferrous Metals to optimize the microcrystalline grain structures of 6000-series alloys (including 6063-T5 and 6061-T6). This results in extrusion products with superior mechanical properties, tighter tolerance limits, and an exceptional surface finish suitable for subsequent anodic treatments.
Chengdu E&I Aluminum Industry Co., Ltd., in line with the business philosophy of "people-oriented, quality value, technological innovation, and win-win cooperation", is dedicated to the research and development and manufacturing of aluminum alloy products with high difficulty, high precision and high requirements.

Our T-slot and structural aluminum systems are deployed across various critical sectors worldwide, offering swift assembly and long-term chemical durability.
By leveraging profiles like the E&I-8-4080 and ENI-8-1640, systems integrators build scalable frame combinations, modular conveyors, and linear drive rails that require low vibration and high rigidity.
Our heavy-duty profiles, such as the ENI-8-40160B, function as modular vertical organizers, storage rack systems, and mobile tool units for automotive workshops, optimizing floor layout efficiency.
Chengdu E&I provides weather-resistant, anodized supports that withstand severe outdoor environments, ensuring long-term rust prevention and mechanical stability for solar panels.
Our strategically integrated supply networks reduce lead times. We offer raw material smelting, custom extrusion die manufacturing, surface finishing, and direct shipping in one continuous flow.
✓ ISO 9001:2015 Quality Management Systems
✓ Automated anodization with zero-waste water recycling
✓ Seamless global customs clearing partners
Located in the industrial hub of Chengdu, Sichuan, we leverage local primary aluminum resources and clean, hydro-powered energy grids. This geographical advantage enables us to maintain a stable cost structure even amidst global commodity fluctuations.
Our state-of-the-art facility operates automated extrusion presses from 600-ton to 3600-ton capacities. This capacity range enables E&I to deliver orders ranging from custom prototyping to large-scale, mass production runs, all with short lead times and robust QA/QC verification processes.
