High Temperature Devices

SF Type - Face Seal

MJ-SF style drop-on-demand single jet dispensing devices are suited for dispensing droplets of fluids such as adhesives, waxes, polymers and liquid metals at up to 240°C. An integrated orifice and wetted surfaces that are almost exclusively glass make MJ-SF devices extremely robust to aggressive materials, including solders.

Two fluid fitting styles are available: VCO and VCR. The VCO fitting is intended for use with the PH-04 and PH-05 high temperature printhead assemblies. Custom, application-specific configurations can also be developed.

AL Type - Luer Connection

The MJ-AL-HT style devices use the same Luer type connector stack as the MJ-AL-01 (with integrated filter) and MJ-AL-00 devices, but use materials that allow dispensing at temperatures up to 150°C. The high temperature actuator is longer than the one MJ-AL low temperature devices resulting in a longer overall length. The MJ-AL-HT devices are intended for use with the PH-41HT high temperature printhead.

For both types of devices, the integrated orifice extends from the housing, allowing visualization of both internal flow and drop formation. Orifice diameters of 20-80 µm are available, allowing customers to optimize their process by selecting drop volumes with a two order of magnitude range. Fluids with viscosity less than 20 cP and surface tension in the range 20-50 dynes/cm at the selected temperature can be dispensed.
