WebThe mold surface temperature must be controlled at a temperature above 180°F (82°C), preferably about 220°F (105°C), and mold closed time must typically exceed 60 seconds for standard cycle or 40 seconds for fast cycle nucleating agent. This is typical for 1/8 inch (0.32 cm) thick parts. WebThe radiative heat transfer should be considered only when the temperature of the mold is high, that is, greater than 85°C, because the radiative heat flow is typically less than 5 …

Solved: Temperature at part and part insert interface

Web1 Mar 2024 · The heat flux at the mold-polymer interface q p can be defined in Eq. (6), in which T m is the mold temperature and T p is the part temperature. ... ... The mold material is P20 and its thermal... WebMold temperatures should be lowered, holding pressure increased, and holding time prolonged to allow for more adequate cooling and curing. Reducing the thickness of the thickest wall sections will also ensure faster cooling and help reduce the likelihood of sink marks. Vacuum Voids figure out gas mileage cost
