3. 1 Uses YUDO have produced the Sequence Injection Timer SIT500 Series to provide a means of controlling the mould filling sequence when using Valve Gate Hot Runner Systems The Sequence Injection Timer enables the Valve Gates of a Hot Runner System to be individually controlled to provide the following benefits 1 Removal or Positioning of Weld Lines Quality of the moulded part can be improved by removing or repositioning of weld lines on visual surfaces or sections where a weld line would cause a weakness 2 Regulation of the Injection Quantity by Gate Operation Flash occurrence or short moulding is improved by the regulation of the Injection Quantity from each individual gate 3 Reduction of Clamping Force Injection is performed with minimum damping force because all of the gates are not opened simultaneously 4 Reduction of Flow Marks Flow marks are minimized by being able to raise the injection rate at the gate 2 Power Supply gt Mains Power Supply Timer case Single phase AC 220V 50 60 Hz gt Injection Signal Input Power Supply DC 24V AC 110V AC 220V Free Voltage gt Solenoid Valve Voltage DC 24V AC 110V AC 220V gt Operating Temperature Range 10 C 50 C gt PCB Structure 1 Power PCB Timer power 2 MAIN PCB MPU out signal input out injection 3 DISPLAY Switch signal input condition display C use 3 Control SIT 500 SEQUEN Panel Layout Sequence Injection Timer SIT 500 1 SIGN
