Product Introduction

Core Competitive Advantages

1. Standard 300 Cycles Per Minute Constant Reciprocating Frequency

   Precision eccentric crank transmission system delivers stable 300cpm bending frequency with negligible speed deviation during long continuous testing, ensuring consistent bending amplitude for all test specimens and eliminating result errors caused by unstable oscillation.
   2.Full Adjustable Fixture Structure For Diverse Specimens

   Upper-lower clamp vertical distance adjustable up to 200mm; eccentric wheel stroke can be modified within 0–50mm, with maximum movable travel of lower holder reaching 100mm. Operators quickly adjust clamping spacing to match standard De Mattia test strips and custom-sized elastomer samples without extra auxiliary jigs.
   3.Independent 6-Station Simultaneous Testing Layout

   Six groups of separate stainless steel clamping fixtures allow parallel testing of multiple samples in one batch, drastically improving laboratory inspection throughput. Each clamp adopts quick-release bolt design for fast specimen replacement and uniform stress distribution on test strips.
   4.Digital Preset Counter With Auto Stop Alarm Function

   Independent digital cycle display panel supports pre-set target bending cycles from 1 to 999,999 times. Once reaching the set value, the machine automatically halts operation with audible reminder, freeing technicians from long-term on-site monitoring and avoiding manual counting mistakes.
   5.Integrated Low-Vibration Integrated Frame

   Thick steel base with four leveling foot pads absorbs mechanical vibration during high-speed reciprocation, keeping the machine stable on uneven workbenches. Internal drive components adopt wear-resistant bearings, running quietly with low noise even after hundreds of hours of continuous fatigue testing.
   6.Corrosion-Resistant Stainless Steel Clamp Assembly

   All specimen holders, connecting rods and positioning parts are precision-machined stainless steel, resisting oxidation and rubber additive contamination after long-term repeated use, maintaining consistent clamping force for every test batch.

Standard Complete Test Workflow

1. Specimen Preparation & Pre-Conditioning
   Cut raw materials into standard De Mattia rectangular test strips, place samples under 23℃ standard lab environment for at least 3 hours to release internal material stress before testing. For crack growth testing, make standardized tiny incision on the middle of specimen surface as required by standards.
2. Fixture Parameter Adjustment
   Adjust vertical spacing of upper and lower clamps and set eccentric bending stroke according to test specification; lock positioning knobs to fix fixture position firmly.
3. Specimen Mounting
   Mount prepared test strips one by one onto six independent clamps, tighten fixing bolts to ensure vertical tension without twisting or offset of samples.
4. Cycle Parameter Setup
   Input target total bending cycles on digital control panel, press start button to launch automatic reciprocating fatigue test.
5. Real-Time Crack Observation
   Pause the machine periodically to inspect specimen surface, record cycle numbers when initial microcracks emerge and measure crack extension length at set cycle intervals.
6. Data Sorting & Evaluation
   After completing preset cycles, unload all samples, organize recorded crack data to compare flex fatigue resistance of different material formulas and finish test report filing.
