成型性能
formability
1.無定形料,吸濕小,流動性差.為了提高流動性,防止發生氣泡,塑料可預先干燥.模具澆注系統宜粗短,澆口截面宜大,不得有死角.模具須冷卻,表面鍍鉻.
1. Amorphous material, moisture absorption is small, poor liquidity. In order to improve the liquidity and prevent the occurrence of bubbles, plastics may be pre drying. Mold gating system should be thick and short, gate section should be large, not dead. Mold need to be cooled, chrome plated surface.
2.極易分解,在200度溫度下與鋼.銅接觸更易分解,分解時逸出腐蝕.刺激性氣體.成型溫度范圍小.
. very easy decomposition, decomposition temperature of 200 degrees and steel. Copper contact more easily, decomposition of escape when corrosion. Stimulation of gas. Molding temperature range.
3.采用螺桿式注射機噴嘴時,孔徑宜大,以防死角滯料.好不帶鑲件,如有鑲件應預熱.
The 3 screw injection molding machine nozzle, aperture should be large, to prevent the dead. It inserts with hysteresis material, such as inserts should be preheated.
