In the precision mechanical engineering, metallurgy, and heat treatment industries, verifying the mechanical properties of materials is a mandatory step to guarantee final product quality. However, QA/QC engineers frequently encounter a major bottleneck when dealing with oversized components, long steel shafts, or thick die-casting mold blocks. These bulky test specimens simply cannot fit into standard hardness testers, which typically limit the vertical testing space to under 170 mm.

Understanding this industrial pain point, Maxlab is proud to introduce a breakthrough solution: the Rockwell hardness tester with a 400 mm high-body. This premium digital equipment expands the boundaries of measurement, allowing modern industrial workshops to handle heavy-duty applications without structural compromises.

The most valuable feature of this upgraded model is its vertical testing clearance of up to 400 mm, combined with a deep throat depth of 165 mm. This architectural improvement allows the equipment to directly accommodate:

By deploying this system, your enterprise no longer needs to waste time, labor, and material costs on destructive sample cutting. You can test commercial products intact, preserving their structural and commercial value.

This machine belongs to the high-end segment of digital hardness testing equipment. The entire testing cycle—including pre-load application (10 kgf), main load execution (60/100/150 kgf), and automatic unloading—is driven by a precise motorized system.

Instead of relying on manual levers that cause machine vibrations and operator-dependent deviations, technicians simply configure parameters on the interface. The integrated smart displacement sensor automatically monitors the indentation depth, calculating and projecting the results directly onto a sharp LCD screen with a fine resolution of up to 0.1 HR.

Supporting heavy metallurgical specimens requires an exceptionally stable mechanical foundation. The frame of this tester is cast from high-quality industrial iron in a single pour, avoiding bolted joints that can loosen over time. The exterior is coated with an automotive-grade electrostatic paint layer that resists workshop oil, grease, and scratches. Its heavy, robust chassis dampens external vibrations, guarantees perfect axial alignment, and secures consistent measurement repeatability.

To help quality control managers evaluate how this unit aligns with production standards, here is the official technical breakdown:

When investing in a specialized industrial tool like a Rockwell hardness tester with a 400 mm high-body, choosing a technically competent supplier is vital. Maxlab Joint Stock Company is the official distributor of high-end hardness testing systems from the Veiyee (Laizhou Weiyi) brand in Vietnam.
