東莞昊科手機殼中框
發布時間: 2019-04-25
名稱:手機殼中框
材質:防火PC料
產品重量:10.5g
產品腔數:1*2
產品壁厚度:1.0mm
熱流道系統:一出四VE型針閥嘴
產品要求:
1.產品為白色防火PC料,為了解決白色防火PC料容易發黃的問題,熱流道設計采用無死角的VE型結構
1.The product is white fire-proof PC material. In order to solve the problem of yellowing of white fire-proof PC material, the VE structure without dead angle is adopted in the design of hot runner.
2.分流板無死角設計,控溫精準,確保產品不會發黃
2.No dead angle design of shunt plate, precise temperature control, ensure that products do not yellowing
3.由于產品間距較小,HOCO選用了微小型的氣缸,在保證模具的強度的情況下又保證了閥針封膠的穩定性
3.Because of the small distance of the product, HOCO chooses the flat cylinder to ensure the stability of the sealing glue of the valve needle under the condition of guaranteeing the strength of the die
開放式和針閥式熱流道的區別其實很簡單,開放式熱流道系統是靠注塑周期完成以后,模具型腔產品在模具模仁保壓冷卻開模瞬間靠開模力將熱流道澆口拉斷的,有的含一點冷料把有的澆口小若針尖。而相對于針閥式來說,它則依靠注塑注射周期完成以后通過外部電磁信號輸入的氣壓、油壓驅動閥針進行動作封膠的。
