Factor one: temperature
For plastic buckets, it's important to know the temperature. This is because temperature has a significant impact on the performance of plastic extrusion and parison. Increasing the temperature of the extruder can reduce the viscosity of the melt, improve the melt flowability, reduce power consumption, and increase the screw speed without affecting the plastic. Mixing and plasticizing effect. In order to achieve this, we can use electronic temperature controllers to stabilize the process temperature and save significant energy.
Factor two: relative humidity in the barrel
Humidity will affect the drying speed of plastic barrels, which is probably better understood. Therefore, the relative humidity of plastic buckets is also an important factor affecting product quality. When the relative humidity in the barrel is low, the water vapor pressure difference between the surface and the dryer is large, and the drying speed is fast, otherwise it is slow.
Factor three: melt pressure
High melt pressure promotes good plasticization and uniform coloration of the mixture. Since it is a blend of high-density polyethylene and low-density polyethylene, and the coloring counter-field, the crystal points and cloud patterns on the parison are reduced. So we will increase the screw speed to increase the melt pressure.https://www.fhpails.com/
