Key factors influencing Display Micro Screws test results

2026,07,27
1. Specimen quality: Surface scratches or internal inclusions in the Display Micro Screws component can reduce flexural strength, leading to lower test results;

2. Loading rate: Rapid loading (e.g., 10 mm/min) tends to induce brittle behavior in the material, whereas slow loading (e.g., 2 mm/min) more closely approximates actual operating conditions;
3. Temperature: Frictional heat may be generated during Display Micro Screws operation; therefore, flexural testing at elevated temperatures is necessary to simulate this environment and evaluate material performance under thermal conditions;
4. Span and specimen dimensions: An excessively small span increases stress concentration, while an excessively large span reduces loading efficiency; dimensions must be set according to standard ratios.
