Manual vs Automated Spring Testing: Which One Improves Production Efficiency?
Mikrosize Manual Spring Tester Technical Manual
Overview of Manual Spring Testing Solutions
Manual spring tension and compression testers are core instruments for material testing and quality control, used to verify spring mechanical properties before assembly in automotive, aerospace, medical and consumer electronics sectors.
As a leading supplier of hardness testing equipment, Mikrosize develops high-precision manual spring testers featuring high accuracy, stable performance and easy operation, suitable for laboratory R&D and production line QC.
Springs are widely applied for energy storage and motion control in precision instruments and heavy machinery. Their performance directly determines product safety and service life, making manual spring testers essential for spring performance verification under controlled test conditions.
Working Principle of Manual Spring Testers
This equipment supports testing of cylindrical, disc, conical, circlip, leaf and special-shaped springs to measure tension, compression, displacement and stiffness for quality inspection.
Compared with automatic testing systems, manual testers deliver direct operator control, real-time parameter adjustment and intuitive observation— ideal for product development and structural optimization. Drawing on decades of experience in hardness inspection equipment, Mikrosize integrates high-end testing functions into easy-to-operate manual devices.
Functional Features
- Load judgment method: Judge product qualification by measuring load (F) corresponding to deformation (ΔH) or fixed compression height (H), applicable to valve and suspension springs.
- Deformation-Based Assessment: Measure deformation (ΔH) or height (H) via applied force (F), ensuring proper fit in space-constrained assemblies.
- Multi-Point Testing: Evaluate performance across the operating range, verifying linearity and consistency—essential for mass production QC.
- Segmented Stiffness Analysis: Calculate stiffness (K) per segment and average values, uncovering hidden behavior variations for performance prediction and root cause analysis.
