This guide provides step-by-step instructions on performing a Nozzle Maintenance Stroke on Haitian MA and JU machines with KEBA 2880 controllers. It ensures proper nozzle alignment, pressure settings, and smooth carriage movement, preventing wear and improving performance.
The Nozzle Maintenance Stroke Guide covers:
✔ Activating the Nozzle Maintenance Stroke – Moving the carriage from the full back position to 5.00 inches
✔ Adjusting Pressure & Speed – Setting the maintenance stroke to 100 psi with 3% velocity
✔ Nozzle Positioning – Aligning the nozzle to touch the sprue bushing for accurate positioning
✔ Transducer Calibration – Checking nozzle position on the KEBA Nozzle screen to ensure proper settings
✔ Finalizing Setup – Verifying the maintenance stroke end position and pressure for optimal performance
This guide ensures proper nozzle function and longevity, minimizing downtime and improving injection molding efficiency.
