AP-TL1
High-pressure casting unit for solid cast tanks and lids.

GAROLL presents the unit AP-TL1, a completely automatized solid cast tanks and lids production cell. This cell has the capacity to produce up to 1100 tanks and 1100 lids per day (3 shifts), having a very large mould frame of 1800mm length x 1570mm width, which can support a double mould with four cavities each, where each cavity can demould a different model.

This unit has the following automatized operations:
- high-casting unit of solid cast tanks
- high-casting unit of lids
- robotized tanks and lids demoulding
- piece positioning on the conveyor belt for their successive hole punching
- tank’s underside hole punching
- lateral tank hole punching
- pre-drying over the conveyor belt while moving the pieces to the seam fettling area
- tank seam fettling
- bottom tank hole’s sponging
- lids seam fettling
- transport box tanks and lids loading

Main unit components
- 1 HPC-201/170 high-pressure casting cell: this is the cell assigned to cast solid cast tanks.
- 1 HPC-201/170 high-pressure casting cell: this is the other cell assigned to cast lids for the respective tanks.
- cells’ servicing robot: this robot is assigned to demould the tanks from one of the HPC-201 cells and the lids from the other cell. It’s following task is to hole punch the tanks in their lower part and, eventually, laterally, and finally deposit the pieces over the conveyor belt.
- conveyor belt: the length of the conveyor belt is such that all pieces reach a certain first degree of drying that permits all fettling operations.
- fettling services robot. This robot performs the following operations: taking of the pieces from the conveyor belt, seam fettling of both tanks and lids, bottom holes’ sponging, loading of finished pieces on the transport box for successive driying process.

Process description.
- Demoulding robot ready to demould the tanks: the robot that services both HPC cells can demould four pieces altogether by means of a vacuum cups’ tool.
- Tanks and lids deposit on the conveyor belt: the same robot, once demoulded all tanks and lids, positions them on the conveyor belt for their successive hole punching process.
- Tanks’ bottom hole punching: the robot, after having changed tool, punches the tanks’ bottom holes by means of a telescopic tool, guaranteeing maximum precision and uniformity during this operation.
- Tanks’ lateral hole punching this same robot punches laterally the tanks wherever necessary.
- Conveyor belt pre-drying: the conveyor belt’s length allows the pieces to reach a certain degree of pre-drying so that all fettling operations can be carried out without any problem.
- Piece taking and seam fettling: the fettling robot takes the pieces with a special tool, and proceeds to fettle all seams from tanks and lids.
- Tanks’ bottom hole sponging: the robot sponges the tanks’ bottom hole and, if necessary, also the lids’ top hole.
- Transport box loading: when all fettling operations are done, the robot positions all fettled pieces on the transport box. It is possibile, if asked, to automatize the transport from this position up to the drying machine.
