Cavity--retractable pin design
Cavity--retractable pin design
(OP)
I want to make 2 derived versions of a part out of one tool, by a core pin touching the textured cavity wall or not; so making a hole or not in an ABS part. Idea is to have no markings on the cavity side after a few tousands shots. does anybody has experience in this?
* what clearence to take between the pin and cavity to avoid burrs
* what about materials of pin and cavity to avoid marks?
thanks

RE: Cavity--retractable pin design
Otherwise, having .003-.004 clearence is plenty (as long as there is appropriate locking, and an adequate amount of sealoff)
core pin material, will depend more on the size and height of pin then anything else (most supplier standard core pins are good enough)

the texture is very light.
