Question #195770

Mould bases (Figure 5) are at the room temperature of 28°C before entering to the heating oven and mould bases temperature change following the graph shown in Figure 6. Calculate the expansion of the mould base width at different temperatures and plot with the time measured in minutes. If the linear thermal expansion coefficient of mould base that is made out of Aluminium is 24 x 10−6 m/mk and linear thermal expansion coefficient of the rollers is 15 x 10−6 m/mk, determine the minimum gap between mould base and the roll

Expert’s answer

Use the formula provided below to calculate thermal linear expansion. The result can be used to estimate the thermal effects on measurement uncertainty.
