wire connection mistake or temperature measuring device damage
Non-uniform of sheet’s horizontal thickness
Dusty in lip
Any problem of runner caused by die’s deformation
The temperature affects the melted plastic’s flow form in the mould runner, and also affect the plastic product’s thickness,The workers should cheek whether the heating device is damaged or not, and every section’s temperature is reasonable or not.Please tiny turn down or turn up the temperature according to the production status, in order to stabilize the mould temperature
Please cheek the actual temperature is coincidental with the initialized temperature or not, the temperature measuring device (thermocouple) should stick into the bottom, and be connected to the mould by the screw. Any of the heating devices that is not working well should be changed.
Please check Gear Pump, screen changer and feedblock. and adjust die lip after extrusion stable
Please adjust die lip by micro adjustable screw
Please clean the die lip
Please give it to manufacture.
Sheet’s Surface Defect
There is too much impurities in the melt
too much impurities in the runner
runner or mould lip parts are scratch
the runner chromium plating layer off.
To re-clean-up mould and connectors
the pressure of entrance side over the machine limit.
the junction part screws didn’t tighten
the surface of mounting surface is irregularity.
Assembly is not in place or sealer damage.
Check extruder settings, Have damaged or stress test error pressure sensor need to be replaced or make recalibration
heating it and re-tighten the screws, Should use uniform torque
to re-clean the surface, if it is necessary, planish with the millstone
Check the installation location of parts, tighten the screws evenly, or replace a new sealer
