Technical Parameters Evolution (2018-2024)

The steady improvements in level ruler accuracy and material yield strength reflect ongoing R&D investments and higher user demands for reliability in professional environments.

Level Ruler Manufacturing Process: Step-by-Step Flow

Raw Material Selection: Premium-grade Aluminum Alloy 6061-T6 & SUS304 stainless steel, offering high yield strength (≥260MPa), excellent anti-corrosive performance, acclaimed for industrial durability.
Casting/Forging: Die-casting for uniformity; forging for compact metallurgical structure, providing impact resistance and dimensional stability.
CNC Machining: Precision edges and ruler body finished on 5-axis CNCs for micron-level accuracy; edge flatness ≤0.05mm ensures reliable measurement.
Surface Finishing: Anodized, powder-coated, or brushed finish to resist scratches/corrosion; laser marking for permanent scale visibility.
Assembly: High-clarity acrylic vials precisely aligned and fixed; rubber end caps absorb shocks; integrated magnets (for certain models) for hands-free use on steel surfaces.
Testing: 100% unit-by-unit inspection: vial level calibration (per ANSI B18.5), scale accuracy, drop test, finish adhesion (per ISO 2409).
