Insert from the rear and cover with thermoplastic resin 1 in the die and add 4g
After cooling and drying the front part of the die, it was cut to a predetermined size using a pellet tie 1F-5 to obtain electromagnetic shielding material 1'+1 piece 1-6. According to this production method (11 fish (,t, Figure 2, that is, cut and l pellets) ~
As you can see from the cut-out diagram, 3-electronic 1f3 was cut) 6) The good thing about the lightning-resistant filler is that it is relatively long, having the same length as the pellet 6, so it is possible to conduct electricity with a small amount of filler. P1 is right, so the high shield effect is 1! V-Ranero and Iro-Fish. However, according to this production 'J Yoshiho University, if the iv2 of the iej electric f1 fiber shoulder [is small and the many fibers are in a roving shape, as shown in Figure 2, the inside of pellets] ~ 6. Conductive filler bundle 3 dispersed 1! It has the disadvantage that it tends to harden and form when molded, and if it hardens, the conductive performance will decrease.
Further, there was a problem in that notches were formed in the molded product due to the molding, and the mechanical properties and electrical properties were significantly deteriorated.
