The main molding plastic bucket condition

Plastic bucket cylinder temperature: barrel temperature is mainly low density and a melt flow rate of the size of PE, and the other also with the injection molding machine type and performance, the shape of the plastic parts of the relevant level. Since PE plastic bucket crystalline polymer, when melted grains to absorb some heat, so the barrel temperature should be above 10 degrees to its melting point. Degrees in LDPE plastic barrels, the barrel temperature was controlled at 140 ~ 200 ℃, HDPE barrel temperature was controlled at 220 ℃, take the minimum rear barrel, the front end takes the maximum value. Plastic bucket mold temperature: mold temperature of crystallization condition have a greater impact plastic parts, mold temperature is high, melt high crystallinity, high strength, but also increases shrinkage. Typically LDPE mold temperature control in 30 ℃ ~ 45 ℃, while the temperature of the respective HDPE and then high 10 ~ 20 ℃.
