Details:Definition: Compression springs used to push a ballpoint pen out of its case and return back into the case. Used for click mechanismsSprings for ballpoint pens must have enough elasticity to compress down to solid height because we tend to push it all the way in before letting the push-pin go. If the spring doesnt have the capacity to compress down to solid height, we will force the spring to take a permanent set, causing the spring to lose its free length, travel, and force. This means that the spring mustnt have a tight index and it must have enough coils in proportion to its free length and wire diameter. The more open your springs diameter is and the more coils you have, the lighter your spring will be.The measurements taken into consideration when designing compression springs for ball point pens are the following:Outer Diameter -This dimension is important for your spring must be able to fit inside the pens "b |
