Active core cooling is an additional option with which the threading core, spindle, and etc. are cooled, thereby significantly reducing production cycle times and increasing thread quality.
The cooling system has two connections. The rear connection channels coolant, such as water, into the mold housing. Inside the housing there is a cooling pipe that conducts the coolant into the mold core, reducing its temperature. The coolant then flows along the outer layer of the coolant pipe out of the mold core so that it can be returned to the coolant tank through the lower connection.
The active core cooling is equipped with dynamic face seals that can operate at a rotational speed of 6 m/s. Thanks to their compact size of Ø 25, Ø 29 and Ø 54 mm, they are perfect for the cooling of threading cores as well as for other dynamic face seals in small spaces.
Example Ø 29 mm
The active core cooling with its 3 mm diameter channel delivers a throughput of 6.5 l/min. at a pressure of max. 3 bar. The system was conceived especially for injection molding applications and easily withstands temperatures from -10 to +120 °C.
The pressure protector reduces the inlet pressure up to 10 bar down to 3 bar, thereby the core elements will be protected. The pressure protector reduces the inlet pressure up to 10 bar down to 3 bar, thereby the core elements will be protected. The output pressure of the pressure protector is fixed by the manufacturer and not adjustable. An advantage for a constant functionality of the core cooling is a temperature filter (No. SR-FI-0001-B.)
