Understanding these settings allows operators to properly control:
-
powder application
-
conveyor movement
-
suction and powder recovery
-
curing temperatures
-
film take-up system
Correct settings ensure proper adhesive powder distribution and consistent curing of DTF transfers.
Main Operation Modes
At the top of the control panel are the system operation modes.
These determine how the shaker and dryer operate.
Auto
Runs the shaker and dryer automatically using the configured settings.
This is the normal mode used during production.
Manual
Allows individual components of the shaker to be turned on or off manually.
This mode is typically used for:
-
maintenance
-
troubleshooting
-
testing machine functions
Stop
Immediately stops the shaker and conveyor system.
Use this when stopping the machine during operation.
Mode / Settings
Accesses additional configuration settings for the shaker system.
These are typically adjusted during machine setup or technician servicing.
Powder Application Controls
These controls manage how powder is applied and removed from the printed film.
Dust
Controls the amount of adhesive powder being applied to the film.
Higher values increase powder coverage.
Too much powder may cause:
-
rough transfers
-
excessive powder buildup
Too little powder may cause:
-
weak adhesion
-
incomplete bonding
Shake
Controls the vibration intensity used to remove excess powder.
This ensures only the correct amount of powder remains on the printed areas.
Proper shake settings help prevent:
-
excess powder on blank areas
-
uneven powder distribution
Conveyor Belt Control
Belt
Controls the speed of the conveyor belt that moves film through the dryer.
This directly affects curing time.
-
Faster belt speed → shorter curing time
-
Slower belt speed → longer curing time
Adjust belt speed carefully to maintain proper curing.
Powder Recovery System
Suction
Controls the vacuum system used to remove excess powder from the film.
The suction system also returns unused powder back into the recovery area.
Proper suction helps keep the system clean and prevents powder buildup inside the oven.
Film Take-Up System
Take Up
Controls the motor that rewinds the finished transfer film onto the roll.
This keeps the film tension consistent during production.
If the take-up speed is incorrect, film may:
-
wrinkle
-
misalign
-
pull unevenly
Final Cooling System
Final
Controls the cooling section at the end of the oven.
Cooling helps stabilize the adhesive before the film is rolled onto the take-up system.
This improves transfer handling and prevents film sticking.
Dryer Temperature Controls
The oven contains two heating zones.
Tube Temperature (Main Curing Zone)
This is the primary curing temperature inside the dryer.
Example shown on the display:
SV: 117°C
PV: 118°C
Where:
SV = Set Value (target temperature)
PV = Process Value (actual temperature)
The PV temperature should remain close to the SV value during operation.
Pre Temperature (Pre-Heating Zone)
The pre-heat zone gradually warms the film before it reaches the main curing area.
Example shown:
SV: 60°C
PV: 59°C
This helps stabilize the film and powder before full curing.
Best Practices for Oven Operation
When operating the Hyper DTF oven:
-
allow the oven to reach full temperature before printing
-
monitor PV temperatures to ensure stable heating
-
avoid adjusting multiple settings at once
-
verify powder coverage before starting production
Incorrect oven settings may lead to:
-
under-cured transfers
-
excessive powder residue
-
weak adhesion to garments
