Forbid trying to run the program without adding sample into the press mould. Avoid
damage the press mould by confronting the tough with toughness.
Press sample with steel ring
Inspect the status: When switching the swing arm, it shows pressing method is the steel ring.It is
no display when switching on the swing arm.
Inspect and adjust the holding pressure and the holding time.Note: If use thin-wall steel
ring(D40×35×15),the pressure must be set lower than 200KN, and if use thick-wall steel
ring(D40×35×15),the pressure must be set lower than 350KN.
Adjust the position of adjusting bolt:Put the steel ring on the positioning table,fill sample,cover
the press mould coverswitch on the swinging arm and screw the bottom plane of adjusting bolt
to the position which distance from the press cover is 1-2 mm. Screw on the locknut (4 of Fig.2)
tightly.
Try to press one sample. The operation step is as flow chart of Fig.9 in page 11.
Set the falling time of press head. After exit mould, the press mould coat should fall to the
position of positioning step and the press cover should just leave the adjusting bolt in order to
push away the swinging arm easily. If the time of exiting mould is too short, it will be hard to push
away the swinging arm and the springs will push out the press mould. If the time is too long, it
will add the backlash of oil cylinder and the time to press sample. Please set the falling time of
press head to the needed time.
Press sample with plastic ring
Inspect the status: When switching the swing arm, it shows pressing method is the steel ring. It is
no display when switching on the swing arm.
Inspect and adjust the holding pressure and the holding time.
Try to press one sample. The operation step is as flow chart of Fig.9 in page 11.
Set the falling time of press head. After exit mould, the press tool coat should fall to the position
of positioning step. If the time is not properly, please set the falling time of press head to the
needed time.
