Croyden 960-2 Rinse Controller Module Netstal Discjet Injection Molder Panel

Croyden 960-2 Rinse Controller Module Netstal Discjet Injection Molder Panel

The Croyden Series 960-2 is a dedicated rinse cycle controller module designed for the Netstal Discjet injection molding system. It manages automated rinse sequences through a panel-mounted interface with a LED Cycles display, labeled Status indicators (Run, Halt, Lock, Setup), and a full button array including Input, Open, Setup, directional arrows, Start, and Stop/Reset. Internally, the module houses a power supply PCB, step-down transformer, and a bank of Humphrey Mini-Mizer 3E1 pneumatic solenoid valves rated at 12VDC and 0-100 PSIG, which sequence the rinse media flow under program control. A rear terminal strip with labeled screw terminals (LL, RES, IT1, IT2, DPN, C, 24C, H) provides the field wiring interface to the host machine.

Applications

Rinse controllers like the Croyden 960-2 are used in optical disc manufacturing injection molding systems — specifically machines such as the Netstal Discjet — to automate the cleaning and rinsing of mold cavities between production cycles. The Netstal Discjet was a high-speed injection molding platform widely used from the 1980s through the 2000s for producing CD, DVD, and related optical disc substrates, where mold cleanliness directly affected disc quality and defect rates. The controller sequences pneumatic solenoid valves to deliver rinse media in a programmed cycle, with operator controls for starting, halting, and configuring rinse programs via the front-panel interface. This type of controller module is still sought after by facilities maintaining legacy Discjet equipment, as well as by technicians and engineers supporting optical disc or precision injection molding operations that rely on original machine components.
