급속냉각·가열장치를 활용한 결정성 수지에서 사출제품의 휨에 대한 연구 A Study on the Warpage of Crystalline Plastics for Injection Products using a rapid cooling and heating Device
pp.1159-1166
This study was developed the rapid heating and cooling device using peltier module for uniform cooling. make the rapid heating and cooling device(RCHD), for traditional water cooling device(TWCD) method and the rapid heating and cooling method warpage were compared and were analyzed and the materials used crystalline PP polymer. various warpage were compared for the process parameters such as packing pressure, packing time, mold temperature. in the crystalline PP polymer, TWCD method has higher warpage than RCHD method and show the result to be a bit more uniform cooling. RCHD method has higher warpage than TWCD method as cooling time and packing time increases and TWCD method has higher warpage than RCHD method as mold temperature increases.
