Gate vestige-small marks left at the injection point-must be consistent, minimal, and cosmetically acceptable in visible parts. Uneven temperature causes irregular vestige size, blush, discoloration, or roughness. Thermocouples stabilize gate conditions to ensure uniform, clean, and repeatable gate appearance.
Consistent tip temperature ensures uniform solidification at the gate.
Stable heating prevents gate blush and discoloration.
Thermal balance across cavities ensures identical vestige appearance.
Fast response avoids cold slugs that distort gate quality.
For cosmetic parts, gate quality is non-negotiable. Thermocouples deliver the stability needed for flawless gate appearance.
