Core Competitive Strengths

1. Dual Test Mode Integrated Design, Wide Energy Compatibility
   One machine realizes two mainstream impact test methods without purchasing separate equipment. Users swap pendulum weights and adjust the fixture base freely to switch between Izod cantilever and Charpy simply supported testing. Multiple energy pendulum sets are optional, supporting flexible matching from tiny low-energy specimens to high-strength reinforced composite samples, and the machine can be upgraded with extra pendulum weights on-site without replacing the whole frame.
2. Lightweight Carbon Fiber Pendulum Assembly
   The swing arm is crafted from high-rigidity carbon fiber composite material, which is lighter and stiffer than traditional metal pendulums. It concentrates impact mass at the striking center to eliminate vibration during impact strikes, cutting mechanical friction loss and improving the repeatability of energy test data. The aerodynamic pendulum head design further reduces air resistance interference during swinging.
3. Touch Intelligent Data Acquisition System
   7-inch bilingual color touch control terminal features intuitive graphical operation, displaying real-time impact energy, residual swing angle and calculated toughness value on screen. The built-in algorithm automatically corrects friction energy loss, stores multiple groups of test records and computes average impact strength in one tap. Multiple unit conversion modes (J, kJ/m² etc.) are supported to fit global laboratory report requirements.
4. High-Rigidity Frame & Precise Standard Fixture

   Integrated thick steel welded main frame avoids deformation during long continuous testing. Standard alloy steel fixture base with adjustable jaw spacing matches standard plastic test bars. Impact cutting edges strictly follow international standard radii (R2 for Charpy, R0.8 for Izod), ensuring consistent striking geometry to eliminate manual fixture adjustment error
   

   

   5. Full Safety Isolation Protection Structure
      Surrounding transparent anti-splash safety shield completely blocks broken specimen fragments during impact tests, effectively preventing lab personnel injury. Independent emergency stop button and automatic pendulum braking function lock the swing arm instantly when abnormal conditions occur, complying with laboratory safety operation specifications. Four adjustable leveling feet stabilize the machine on uneven countertops to avoid test deviation caused by tilting.
   6. Low Maintenance Modular Structure
      All pendulum shafts adopt imported low-friction ball bearings to extend service life and reduce regular lubrication frequency. Fixture components are detachable for quick residue cleaning after fractured specimen testing; spare pendulum weights and cutting blades can be replaced independently without professional technical assistance.
