How is the pin needle (non thimble) worn out of the plastic mold?
I suggest you buy directly, need to make very precise needle matching instrument, non general machinery can be made, also in the process of product processing, do not take the release agent, it is easy to break the spell of needle, needle often change, you have to do without dismantling the case of mold, you can change the needle. Go buy it, do not suffer
Pull out of the drawing die. Just like copper wire
Directly to buy, you have to cough up, there is such a buy, mold hardware there is slightly.
