Mold Temperature Controller with 2-step Sprue Temperature Switching Function

Hot/Cold switching of sprue part
Prevents stringiness and shortens cycle

- Quickly switches the temperature of sprue part
  between hot and cold
- Quick sprue solidification enables shorter molding cycle
- Highly effective against stringness
- Low temperature (95ºC) type
  and high temperature (120ºC) type

The max. flowrate is given for a discharge pressure of 0.1 MPa.

■ Normal temperature control process

In continuous molding, hot spots can occur in sprues. If left unattended, sprue solidification can slow, which can lengthen production cycles and cause stringiness.

■ Sprue cooling

In the cooling process, the cooling circuit opens to supply cooling water to a purpose-specific bush and cool the sprue. This process quickens sprue solidification.

■ Product take-out and sprue heating

The hot circuit is opened to heat the sprues quickly and make production ready for the next injection cycle.
