Platens keep high parallelism
![日本特許出願済](./img/se-ev-s-connector/img-04-en.png)
Thermal Free Platens that minimize any irregular deformation due to heat,resulting in a platen that keep platen parallelism and straightness.

Temperatures differ above and below the platen
because heat propagated to the frame.

Deformation is uneven across the platen, so the platen does not stay flat.

Heat propagates symmetrically upwards/downwards.
Temperature is the same above and below the
platen.

Upward/Downward deformation is even across the platen, so the platen stays flat.

[ Resin cost ]
A stable molding process is enabled even if the regrind ratio is increased by 10%. So the use of virgin material can be reduced.
Helps to reduce costs and improve productivity
Additionally, with its long reach, it reduces the amount of sprue plastic material and shortens the mold opening stroke, which leads to a faster cycle.
Moreover, the nozzle can be detached quickly and easily, which facilitates cleaning and shortens machine down time.

The FTCIII nozzle provides a wider process window without causing stringing or clogging.
This eases the difficulty of setting molding conditions.
