The mould is used for transformer skeleton, pin needle used in mould and some small, I have seen a small circular needle 0.5mm; there are square or flat, is also very small, only 0.3 x 0.7mm. The accuracy of these needles is very strict, and the tolerance is only 0.002mm. Take the round needle as an example, 0.5mm needle, needle body diameter 0.8mm, needle diameter 1.2mm, 0.8mm and 1.2...
Directly to buy, you have to cough up, there is such a buy, mold hardware there is slightly.
Pull out of the drawing die. Just like copper wire
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
