“…S. Huang et al [17][18][19][20][21][22] have compared the performance of oil heating versus induction heating and found the latter to give best replication of micro structures. They also noticed that increasing the mold temperature above the phase transition temperature does not significantly improve the replication ability.…”

“…Mold surface heating, such as induction heating [10][11][12], high-frequency proximity heating [13,14], and gas-assisted mold temperature control (GMTC) [15,16], can provide sufficient heating rates without significant increases in cycle time. In recent years, we have conducted systematic study of mold surface heating and mold surface localization heating of the processing characteristics.…”

A hot gas is used for heating the cavity surface of a mold. Different mold gap sizes were designed. The mold surface temperature was heated to above the glass transition temperature of the plastic material, and the mold then closed for melt filling. The cavity surface can be heated to 130 ∘ C to assist the melt filling of the microfeatures. Results show that hot gas heating can improve the filling process and achieve 91% of the high aspect ratio microgrooves (about 640.38 m of the maximum of 700 m). The mold gap size strongly affects the heating speed and heating uniformity. Without surface preheating, the center rib is the highest. When the heating target temperature is 90 ∘ C or 100 ∘ C, the three microribs have a good uniformity of height. However, when the target temperature exceeds 100 ∘ C, the left side rib is higher than the other ribs.

“…Therefore, RCHM process can shorten the whole production process and reduce the environmental pollution and production cost. Additionally, RHCM process has also shown a rising application in microinjection moulding (MIM) field because it can significantly improve replication accuracy of the micro-featured plastic parts [5][6][7][8].…”
