Aluminium U Profile for Screen Printing

A1 Series aluminium u profile: Ultra-Light 18×22×1.2mm Screen Printing Frame Extrusions

Where precision meets featherweight performance - our A1-series aluminium U profiles set new benchmarks for sub-40cm screen printing frames. Engineered with 18×22×1.2mm micro-channel geometry and Webster hardness 10-15, these extrusions deliver surgical-grade stability at just 0.28kg/m.

Technical Specifications
◆ Material Composition

• Alloy Designation: A1-grade (EN AW-6063 T5 equivalent)

• Profile Straightness: ≤0.1mm/300mm (ISO 8578 Class B)

• Weight-to-Stiffness Ratio: 37% better than conventional frames

• Thermal Stability: 0.025mm/℃ expansion coefficient

Engineering Innovations
❶ Micro-Channel Technology
Precision-drawn U-profile architecture achieves:
✓ 25% vibration damping vs standard L-profiles
✓ Integrated 1.5mm registration notches
✓ 0.5mm emulsion clearance channels

❷ Edge-Perfect Design
Radius-optimized corners (R0.4mm) ensure:
→ 18% reduced squeegee wear
→ Seamless corner key integration (4mm/6mm options)
