How To Adjust The Temperature of Each Zone of The Plastic Granulator

The plastic granulator is a kind of equipment commonly used to produce plastic granules. The temperature regulation of each area is very important for product quality and production efficiency. The following will introduce in detail the temperature regulation method of each area of the plastic granulator.

1. Feed section temperature adjustment:

The feed section is the first area of the granulator, and its temperature adjustment is very important for the melting and uniform feeding of plastics. Generally, according to different plastic materials, it is recommended to set the temperature of the feed section between 180-210 degrees Celsius. The temperature of the feed section can be controlled by adjusting the power and position of the electric heating coil, as well as the cooling water temperature of the feed section.

2. Pressure section temperature adjustment:

The pressure section is the area where the molten plastic material is pressurized and homogenized. In this area, the temperature needs to be kept within a suitable range, generally recommended to be between 200-230 degrees Celsius. The temperature of the pressure section can be controlled by adjusting the power of the electric heating coil, the position of the electric heating coil and the temperature of the cooling water.

3. Temperature adjustment of the screw section:

The screw section is the area where the molten material is extruded and homogenized. In this area, the temperature needs to be kept within a suitable range, generally recommended to be between 200-230 degrees Celsius. The temperature of the screw section can be controlled by adjusting the power of the electric heating coil, the position of the electric heating coil and the temperature of the cooling water.

4. Die temperature adjustment:

The die is the part that extrude the molten material into shape. The temperature adjustment is very important for the surface quality and dimensional stability of the product. Generally, it is recommended to set the temperature of the die between 180-220 degrees Celsius according to different plastic materials. The temperature of the die can be controlled by adjusting the power of the electric heating coil, the position of the electric heating coil and the temperature of the cooling water.

5. Cooling section temperature adjustment:

The cooling section is the area where the extruded plastic particles are cooled and solidified. The temperature adjustment is also very important for the quality and dimensional stability of the product. Generally, the temperature of the cooling section should be adjusted according to the specific product requirements. The temperature of the cooling section can be controlled by adjusting the flow and temperature of the cooling water and the operating speed of the fan.

In summary, the temperature of each area of the plastic granulator needs to be adjusted according to the specific plastic material and product requirements. By adjusting the power, position and cooling water temperature of the electric heating ring, as well as adjusting the cooling water flow and the operating speed of the fan, the temperature of each area of the granulator can be accurately controlled, thereby ensuring product quality and production efficiency.
