Profile : We always use raw material 42CrMo4 to produce the popular pressbraketooling and all the tooling are hardened and ground to reach the hardness of 48~52 HRC (Rockwell hardness), the procedure for holistic heat treatment is as follow : quenching + tempering + 860 °C Oil quenching + 390°C Tempering . At last ,the tolerance of tooling we can control is +/-0.02mm Range: we can manufacture Acute tooling, Goose neck punch ,Single V die ,2 V die ,Multi V die block, die holder and upper adaptor for punch. Popular size for the tooling is:26*97*835mm ,26*150*835mm, 60*60*835mm, 56*120*835mm The longest bottom die we can make is up to 10 meters ( size:220*220*10,000mm) Case: Year 2014, we manufactured one upper tooling (size : 25*165*6100mm ) and bottom tooling(120*120*6100mm) to one of famous machinery dealer in Australia . Notes: Also we can make special tooling such as adjustable channel lock bottom die which is used for big capacity pressbrake to bend thick steel plate .
