EcoTemp
Variotherm temperature control, i.e. a systematically gradated
mould temperature over cycle time, provides a variety of benefits
for the process, the part surface and strength as well as for the economic efficiency. The temperature of the pre-heated cavity wall
rises as the hot polymer melt is injected into the mould. Mould
cooling begins after the cavity has been filled. Only then is the
part temperature reduced to the level required for demoulding.
Benefits of variotherm temperature control vs. conventional
mould temperature control

Compact water-operated temperature control system K

The EcoTemp from SINGLE makes changing to
variotherm mould temperature control especially easy. With EcoTemp, temperature control
systems operating with user-defined performance data and operating temperatures can be
combined to create an intermittent flow through
the mould.

▸ Longer holding pressure even in areas away from the gate
▸ Requires less injection pressure and clamping force
▸ Reduces internal stress during injection compression moulding
of optical parts
▸ More accurate reproduction of surface details of micro- or
nanostructures, surfaces with piano finish
▸ Better reproduction of surface effects such as self-cleaning or
anti-reflection effects
▸ Ensures a more homogenous orientation of glass fibres in
technical components
▸ Increases the welding time for melt fronts and reduces the
occurrence of weld lines
▸ Less risk of warpage caused by shrinkage
▸ Better dimensional stability and shot-by-shot consistency
▸ Does not require any changes to the mould construction
▸ Optimised cycle times due to lower-temperature cooling
Benefits of SINGLE EcoTemp
▸ Durable valve technology
▸ Short control signal response times
▸ Optimised ramp up times thanks to two temperature settings
per circle: standby and automatic temperature
▸ Lower energy consumption than classic constant temperature
control
