High response hydraulics speed multi-shot moulding
Designed for all types of multi-component technology, a multi shot injection moulding machine uses a high-response hydraulic system.
Mould temperature controllers heat up quickly
Easy-to-maintain mould temperature controllers have fast and accurate heat-up time and can accurately maintain programmed temperatures.
For small material throughputs a single desiccant system and for medium to large material throughputs two desiccant systems are used.
The DDT model offers: a.
High saving of energy.
b.
High linear dew-point (up to - 50).
c.
Fully automatic operation.
d.
Operation without refrigerated water.
e.
Operation without compressed air.
In terms of energy saving, the return air from both the process and regeneration is intercepted and recycled, hence reducing the amount of wasted energy.
In more traditional driers the return air is cooled using water and is then reheated again, making for increased running costs.
Any cooling that is required before the air reaches the blower is achieved by a small electric fan.
This procedure eliminates the need for water cooling and gives the DDT dryers a high saving of energy, typically up to 30 - 40% compared with traditional dryers.
Sandretto UK's latest range of drier can link a number of materials hoppers to a single dehumidifier generator unit.
The dehumidifier supplies the air unheated to the hoppers hence eliminating the need to lag pipes.
Each hopper has its own heater and booster blower attached that controls the flow of air through the hopper.
If the hopper is turned off for material change a valve automatically closes off the dehumidified air supply to that hopper.
Chris Whitlam, National Manager for Sandretto Ancillaries and Automation reports that "our ancillary sales have this year exceeded budget and expectation.
Not only do moulders prefer one-stop-shopping with their injection moulding machinery supplier, they are also ever more cost conscious.
This is good news for our energy saving driers and bodes well for their success into next year.".
