Hybrid Die combines the advantages of conventional dies (Coat Hanger Die, Inclined Land Die) as shown below
- Prevents resin degradation and its adhesion on the flow channel surface in long term operation. (Advantage of Coat Hanger Die)
- Robust structure for thickness distribution change resulting from deformation of die caused by the inner pressure of polymer melt (Advantage of Inclined Land Die) (Hybrid die delivers superior performance at higher output, the use of higher viscosity polymer or wider die)
Collaborative development with AX Molding Co.,Ltd.
Motors are mounted on the adjust bolt units and adjusted without manual operation.Uniform displacement of the lip is possible by driving all motors at the same time
After opening all lips at the same time when starting up the device and performing early discharge (purge) of deteriorated resin, it is possible to instantly restore the lip opening to the previous production state. (The controller has stored the motor displacement and heat bolt output in the production state)Development of fully automatic T-die for automatic thickness control system
The operator only measures the lip and does not need to operate the T-die.
Shorten the start-up time from the line start-up to product collection and reduce waste resin.Completion of Temperature Rise
Measure the lip opening just before the line starts up.- Transfer the measuring data directly to J-TAC and immediately instruct each motor to adjust the opening.
- The initial lip opening is automatically adjusted just by measuring a few times.
Manufacturing Operation
After the deteriorated resin is discharged, film manufactured immediately.- Command the T-die to adjust the motor or heat bolt from the thickness gauge data.
