      Decrease

    • B. 

      Increase

    • C. 

      No change

  • 2. 
    How would torque performance generally change when Radius Bend is small ?

      Become worse

    • B. 

      Become better

    • C. 

      No change

  • 3. 
    Customer desires to make ACTONE less rigid while keeping same ID and OD.  What would you tell them?  
    • A. 

      We cannot make less rigid and more

    • B. 

      Let’s decrease number of filar

    • C. 

      Let’s increase number of filar

  • 4. 
    ACTONE can be made of SS304 and SS316.  How torque performance and rigidity would differ?
    • A. 

      SS304 has better torque and lower rigidly

    • B. 

      SS316 has better torque and higher rigidity

    • C. 

      No above

  • 5. 
    Customer desires to improve surface friction performance of torque coil. What would you tell them?
    • A. 

      We will do PTFE coating, it would not affect torque performance

    • B. 

      We will do PTFE coating, however, it would affect torque performance

    • C. 

      We will do PTFE coating, torque performance would be better

  • 6. 
    Which ACTONE tends to get wires frayed?
    • A. 

      More filar count

    • B. 

      Less filar count

    • C. 

      No impact (the same)

  • 7. 
    Customer would like to know if  ACTONE’s performance changes in case, they change the pitch wider.  What would you tell them?
    • A. 

      We cannot change pitch.

    • B. 

      Rigidity gets higher, tends to get wire frayed and impact torque performance

    • C. 

      Rigidity gets higher, torque performance gets worse and other no impact
