Clamp Slots

The function of clamp slots is to provide a ledge for the clamp to hold the mold base in the press. The main problem we face with the clamp slots in the design of the mold is to make sure that mounting holes are in close proximity to allow the clamps to reach the edge of the slot. Platen holes used to be different in each press manufactures specification. The industry has now standardized these hole locations so molders can use presses made at different manufactures. Another problem we have had with clamp slots is how high they are in relation to the bottom and top of the mold. The designer must also take care to design the water patterns so the water lines do not fall in line with the bolt holes.
