Domestic Fully Automatic Universal Hardness Testers
— breaking the foreign monopoly
One Machine Does the Work of Three: The All-Round Champion for Industrial Quality Control
In the fields of metal testing and materials R&D, hardness testing is one of the most fundamental steps in quality control. Yet, many companies have long faced a practical dilemma:
Buy one machine for Brinell, another for Rockwell, and yet another for Vickers.
Three separate machines mean triple the investment, triple the maintenance costs, and the tedious process of moving samples between different stations. The result? Low efficiency, excessive floor space requirements, and difficulty in ensuring data consistency.
While imported universal hardness testers can indeed solve these issues, their steep price tags (often running into the hundreds of thousands), lengthy lead times, and expensive after-sales maintenance keep many companies at bay.
Now, Laihua has delivered the ultimate domestic solution.
1. Full-Spectrum Test Force Coverage: From Micro-Precision Parts to Heavy-Duty Industrial Workpieces, All in One Machine
This universal hardness tester features an ultra-wide test force output range:
3kgf to 3000kgf (0.3N to 29.4kN) for comprehensive, full-range precision coverage.
3kgf Light Load: Effortlessly handles hardness testing for thin case-carburized layers, surface-quenched layers, coatings, and micro-precision components.
30kgf to 150kgf Medium Load: Covers Brinell, Rockwell, and Vickers testing for standard materials, including carbon steels, aluminum alloys, and copper alloys.
3000kgf Heavy Load: Directly meets the Brinell hardness testing requirements for heavy-duty industrial workpieces such as large castings, forgings, and rolling mill rolls.
No need to switch equipment or relocate to different testing areas. A single machine covers the entire testing range for all material categories.
Comparison with Traditional Solutions:
| Testing Requirements | Traditional Solutions | Shancai Universal Hardness Tester Solution |
|---|---|---|
| Vickers Hardness for Micro Components | Dedicated Vickers Hardness Tester | Completed on the Same Machine |
| Rockwell Hardness for Standard Components | Benchtop Rockwell Hardness Tester | Completed on the Same Machine |
| Brinell Hardness for Heavy-Duty Components | Large Brinell Hardness Tester | Completed on the Same Machine |
2. Star Turret: True Versatility in a Single Machine
The core differentiating design of this equipment is its premium star turret structure.
When switching scales, traditional universal hardness testers require manual removal and realignment of the indenters, which is a tedious process prone to positioning errors. The star turret design makes all of this effortless:
Brinell, Rockwell, and Vickers indenters are all loaded simultaneously. Simply rotate the turret to switch—no more repetitive dismantling and reassembly.
Specifically, it offers the following advantages:
Simultaneous Multi-Indenter Installation: The turret can hold multiple indenters for different scales at the same time. Just rotate to the working position for the required scale, achieving second-level switching.
Support for Multiple Brinell Indenters: For scenarios requiring various indenter specifications (φ2.5mm, φ5mm, φ10mm) simultaneously, there is no need to swap them back and forth, effectively doubling batch testing efficiency.
Guaranteed Positioning Accuracy: The turret utilizes a precision positioning mechanism. After each switch, the indenter is automatically centered, ensuring extremely high repeatability and preventing any loss of testing accuracy due to frequent scale changes.
Comparison with Traditional Single-Indenter Equipment:
| Operation | Traditional Single-Indenter Equipment | Star Turret Equipment |
|---|---|---|
| Indenter Replacement | Manual removal → Reinstallation → Alignment → Calibration (5–10 minutes) | Turret rotation switch, completed in under 10 seconds |
| Multi-Scale Testing | Sample loading on multiple machines in rotation | Continuous testing on a single machine |
| Batch Testing | Efficiency limited by indenter swapping speed | Doubled efficiency; the top choice for batch screening |
3. Fully Automatic Focusing System: Matching Imported Standards with Ultimate Precision
The core competitiveness of high-end hardness testers lies not only in their mechanical structure but also in their level of automation and intelligence.
Equipped with a fully automatic focusing system, this Shancai universal hardness tester delivers:
Automatic Positioning: The indenter automatically approaches the sample surface to precisely locate the testing point.
Automatic Focusing: The optical system focuses automatically, eliminating the need for manual adjustments.
Automatic Testing: Test forces are automatically applied, held, and unloaded, with the entire process under program control.
Automated Data Output: Indentations are automatically identified, measured, and calculated, with results output directly.
With zero manual intervention throughout the entire process, human operational errors are completely eliminated.
The performance of this system directly benchmarks international high-end universal hardness testers such as ATM. In core metrics including test force accuracy, indentation measurement repeatability, and multi-scale switching consistency, its precision and stability are entirely on par with imported equipment.
