The economic solution for variothermal temperature control
In corporation with the University Pforzheim and after 4 years of development, we are introducing a new energy- and cost saving system for selective heating of critical areas in injection mold cavities on the market.
A patented combination of turbulent airflow, highly efficient 3D-printed heating-nozzles, tailored to the molded part, air acceleration based on Venturi-principals and a heat recirculation-sleeve contributes to a highly efficient variothermal process control system for injection molding.
The biggest challenges:
● Are your parts having knit-lines or microstructure surfaces?
● Do your parts have an unfavorable flow-path to wall thickness ratio?
● Would you like to use variothermal temperature control but not across the entire mold surface?
● Does the high energy consumption and cost of conventional systems let you hesitate?
TURBOTHERM® is the economic system for energy-efficient and tailored impulse-heating of injection molds and for part improvement.
Outstanding product quality through:
● Elimination of visible knit-lines
● Precise reproduction of the cavity surface even at complex geometries
● Longer flow-paths possible in thin-walled parts
● Product-specific 3D nozzle/sleeve
with TURBOTHERM® 400x
Knit Line width [µm]
The graph shows a rapid decrease in knit-line width; a visible reduction of up to 100% is possible with this method. The accuracy to reproduce surface details of the cavity can be increased at the same rate.
Temperature-increase of about 5-10°C per second based on surface roughness: grained surfaces heat up twice as fast as mirror finished surfaces.
The unit consumes an average of 1.4 kW (reference cycle: 28.9 sec. including 3.2 sec. heat time over 8 hrs.) and the consumed hot air can be reused.
In addition, the compressed air consumption with an average of about 30 to 120 Liters/minute at 0.3 MPa is rather low.
● No modification of the injection molding tool required
● Can be retro-fitted, also in multi-cavity tools
● Stable and repeatable process
