What are the applications of LM100?
Automotive & Aerospace
Testing of engine blocks,crankshafts,gearboxes,
aircraft structural parts,and fasteners toensure materialstrength anddurability.
Heavy Machinery & Equipment
Quality inspection of construction machinery(excavator buckets, hydraulic cylinders), industrial gears, and bearing housings during manufacturing or maintanence.
Metal Processing & Manufacturing
Testing of castings, forgings, stamping parts, and welded joints in steel mils, foundries and hardware factories to control production quality.
Petrochemical & Pipeline Engineering
On-site testing of pressure vessels, pipelines and flange connections to verify material hardness and prevent corrosion-related failures.
Maintenance & Repair
Evaluating the hardness of worn or repaired components(e.g. machine tool guides, turbine parts)to determine if they meet reusability standards.
Quality Inspection Labs
Supplementary testing for large workpieces that cannot be moved to stationary hardness testers, improving testing efficiency and flexibility.
