IMP Dispensing Valve

For over 20 years, the Rotary Auger valve dispensing system has been recognised as the work horse for many fluid dispensing applications. First introduced by Techcon Systems, in 1987, the TS5000 Series Auger valves has solved many dispensing problems engineers faced, most notably the inability to dispense highly accurate deposits of high viscosity solder paste, silver filled epoxy for Die Attach applications and high viscosity epoxy for Dam Writing applications (Dam and Fill) to name a few.

In 2008, The TS7000 IMP (Interchangeable Material Path) dispensing system was introduced and attracted much attention. This Hybrid valve incorporated the accuracy and robustness of the original TS5000 Auger valve dispensing system but with the versatility of replacing a metal cartridge similar to that of the DMP.

This modular design would allow engineers to easily and confidently maintain the TS7000 IMP valve with no special tools required. A U-Cup seal design replaced the traditional lubricated o-ring, as the sealing method which further enhanced the TS7000’s ability to dispense filled fluids and control fluids at the lower end of the viscosity range.

Featuring a “divorced” motor, the TS7000 dispensing system utilises a coupling that separates the motor from the wetted area.  At some point, all valves suffer from the lack of maintenance, due to ever increasing outputs demanded by production teams. If for any reason the TS7000’s integral U-Cup seal was operated past the regular working life, fluid could leak back towards the coupling but would not penetrate the precision motor.

An encoder option provides intelligent closed-loop feedback control ensuring the highest possible level of control and a DMP kit is optional for retrofitting existing TS7000’s should the dispensing process change.  For more information please click here.
