Key Advantages

· CNC-machined panel interfaces with ±0.5 mm dimensional tolerance and controlled cumulative deviation within 1.5 mm in multi-cycle casting applications.
· Lightweight modular aluminum system with tool-light manual assembly and zero crane dependency for repetitive structural grid construction.
· Pin, wedge, and bolt connection system with integrated alignment grid for rapid cross-section adjustment and modular assembly consistency.
· Rigid extruded profile structure with hydrostatic pressure resistance up to 60 kN/m² enabling fair-faced concrete finish without secondary plastering

Application Scope

· High-rise residential developments
· Commercial office buildings
· Mixed-use real estate projects
· Infrastructure structures with repetitive column grids
· Industrial building frameworks

Comparison with Traditional Column Formwork Systems

Performance Factor	Aluminum Formwork	Timber Formwork	Steel Formwork
Reuse Cycles	High (300–500 cycles)	Low (5–10 cycles)	Medium (50–100 cycles)
Dimensional Accuracy	High and stable	Variable	Moderate
Labor Requirement	Lower	High	High
Construction Speed	Fast cycle compatible	Slow	Medium
Surface Finish Quality	Smooth, reduced finishing work	Rough	Moderate
Material Waste	Low	High	Medium

Quality Control Considerations

· ERP-based production management system. Batch traceability with raw material Mill Test Certificates (MTC).
· CNC-machined dimensional inspection. Strict verification of critical structural interfaces.
· Material compliance verification. 6061-T6 aluminum alloy tensile performance testing prior to production.
· 100% engineering trial fit-up testing for panel and connection alignment verification prior to shipment.
· Full-process inspection tracking from extrusion, machining, welding NDT (if applicable), assembly to final packaging.
