Discussion is made with focus on the influents of ZHY-2000 finishing oil on the product quality and steady running for polyester filament by hotpin spin-draw system.

Over hot is the main reason of PIN switches 'failure, therefore thermo-resistance and device dissipation power measurement to estimate the inner temperature accurately is necessary dramatically.
Based on the experiments, the thermal balance of hot runner system and condition of temperature control around the pin point gate were fur - ther analyzed.
