Crimping machine is applied in production line of high voltage composite insulator (polymer insulator) to crimping metallic end fittings to FRP of insulator. Model 165 is available for insulator with voltage up to 800KV

SKU: C-CRMP-165 Category:
General Details

Crimping machine is used to crimp the metal fittings of high voltage insulators during insulator production process, it is an vital and essential production machine of composite insulator (silicone rubber insulator). With high pressure from hydraulic power force, crimping machine press the metallic fitting from all direction and make the metal fittings well attached to the fiber glass rod of composite insulators. Some new manufacturers like to search “Fitting pressing machine” on internet to start their new factory of composite insulators, but acutally we call it crimping machine, in Chinese “压接机” which is more common and professional.

This crimping machine is necessary for manufacturering of composite insulator,which is also known as “silicon rubber insulator” or “polymeric insulator”. With this crimping machine 165, composite insulator of different type, including pin type polymeric insulator, post type polymeric insulator,suspension polymeric insulator, tension polymeric insulator (long rod insulator) can be crimped with this machine, voltage of which can be from 11KV up to 800KV.


  1. Modern design philosophy
    Designed with “Soft crimping” theory, it has function of slow crimping and pressure holding function and it’s capable to set pressure by different section, which assure best crimping quality. This function is owned by Contune Intl and its collaborating factory only, effect of which are particularly obvious on insulator of high mechanical load.
  2. Double control to achieve best crimping quality
    Both crimping quantity and crimping force are used to control crimping quality. So under same condition, this machine can achieve crimping effect with maximum tensile load and minimum discreteness, which largely solves the bad effect caused by different hardness of ball and socket fitting, improves the effect of crimping.
  3. Higher speed, higher efficiency
    With special optimization by Contune Intl, this machine is faster than average product from other supplier, enabling manufacturer to have higher efficiency in their production.

Compared with crimping machine model 140, this model 165 has bigger opening diameter, bigger pressing force of crimping and more advanced function like cantilever-arm screen,which makes it enable to suit bigger post insulator with higher voltage level, greater cantilever strength, bigger dimater of fiber glass core and bigger flange base.  To be more advanced, sound detective system is optional configuration for user to check crimping quality of fitting, which named “acousitc emission system”. With this AES, user will be able to judge whether there is cracks in FRP/ECR rods during crimping process. The curve on screen will indicate sudden crack of structure and help user to observe and make judgement of FRP rods status.
