EcoONE-Series Thermal Expansion Allowance Hot Sprue Bushings

THERMAL EXPANSION ALLOWANCE The expansion factor must be taken into consideration prior to machining and installing the nozzle. This factor must be added to the nozzle nominal “A” dimension. Z-1 = Nozzle Length “A” + “BE” Thermal Expansion (ΔL) - Nozzle Plate Thickness The formula for determining the thermal expansion is as follows: BE = “A” dimension * 0.0000115 * (nozzle setpoint temperature - mold temperature °C) Note: The expansion coefficient for °F is 0.00000633 EXAMPLE: Nozzle “A” dimension 120mm, setpoint temperature 260°C, mold operating temperature 50°C. BE = 120mm * 0.0000115 * (260° - 50°) = 0.2898mm. Thus nozzle length “A” 120mm + BE 0.2898 = 120.290mm
