Service Tip
Mold Assembly and
Torque Requirements
Longer mold life can be
achieved by following a few basic rules. Be sure to clean all parts and
mating surfaces thoroughly before assembly. Always be sure parts are
properly aligned and use proper torque requirements. To assure that parts
are square, start with a good working surface such as a Besser portable
mold jig. A visual inspection is suggested to make sure parts are not
burred or scored. NOTE: Always start with new lock washers and
only use a brass hammer.
-
Outside division plates should be torqued to 625 - 675 ft. lbs. (930 -
1005 newton-meters). Outside division plates with cutouts for face
liners should be torqued to 175 - 195 ft. lbs. (260 - 290 newton-meters).
-
Due to the differing grades of vibrator bolts and vibration systems,
please consult factory.
-
Core bars should first be snugged initially front and back.
- Then core bars
should be torqued to 70 - 90 ft. lbs. (105 - 135 newton-meters). Align
front and back as uniform as possible to the mold side bars. Check
cores for center between division plates to assure uniform block
dimensions. (A wire can be secured through the hold down bolt heads as
a safety to prevent the bolts from coming loose during constant
vibration.)
- Secure plungers to
stripper head plate - 100 - 140 ft. lbs. (150 - 210 newton-meters).
- Align the stripper
shoes.
- Threaded inside
division plates should be torqued to 40 - 50 ft. lbs. (60 -70
newton-meters). Tanged inside division plates should be torqued to 100
- 120 ft. lbs. (150 - 180 newton-meters).
- End liners should
be torqued to 100 - 140 ft. lbs. (150 - 210 newton-meters).
- Stripper shoes
should be torqued to 65 - 75 ft. lbs. (100 - 110 newton-meters).
- Center Posapac
Vibrator Weights as close as possible to assure uniform vibration and
that the nuts face the outside of the mold.
