MARTIN dispense systems use stored look-up tables to compensate for viscosity variations caused by temperature changes. This results in constant dispense volumes under production environments. However, despite of available compensation a precise and driect closed-loop control of medium temperature itself would lead to constant viscosity and hence provides stable dispensing results.
For DOTLINER machines we offer dispense heads with heating option to maintain the medium temperature stable at the nozzle outlet. The operation temperature is set slightly above ambient usually, so that the active control may keep the medium between 20°C and 50°C stable to +-0.2°C.
By this technology the viscosity is controled at the location of importance in the entire dispenseing system over the full cartridge.
