A netizen left a message below the video asking, ‘I am currently using a core pulling board in the plastic film for my PC, which is only 2.4mm thick and prone to eccentricity. Do you have any good material recommendations?’?
A 2.4mm thick sheet is prone to deviation, which is caused by insufficient strength. You should increase the strength and toughness of the sheet to ensure that it does not deviate and does not break.
I recommend LG mold steel, which has high hardness and good toughness. LG’s toughness is 8-9 times that of DC53, with a hardness of HRC54-58. Its toughness is so good that it does not break even when bent.
Boss Yu said that LG mold steel has hardness and toughness. The hard material with a heat treatment of 60 degrees and the leftover tail material from wire cutting can be bent 180 degrees without breaking, and can bounce back after unloading force. LG has toughness and rigidity, but it was snatched away by a group of friends who make plastic molds. The wire cutting slender core is very useful.
