Plastic pelletizing machine

The plastic pelletizing machine can also be called a plastic granulator, serving as a very important machine in plastic waste recycling line. The plastic granulator can be used to melt waste plastics and extrude plastics such as PP, PE, HDPE, LDPE, and LDPE for reuse in the plastic industry.


Introduction of the plastic pelletizing machine

The model of this plastic granulator machine is mainly divided according to the diameter of the screw press.

  1. The material of the screw is 45 # steel, 40CR, 38CRSI. Customers can also customize chrome plating, nitriding, and other processes to extend the service life of the machine according to their plastic processing characteristics.
  2. The reducer of the plastic pelletizing machine adopts a hard gear surface reducer. Reducer is an important component of plastic granulator, so quality is particularly important. At present, the quality ranking of common reducers on the market is old-style snail reducer <common reducer <semi-hard gear surface reducer <hard gear surface reducer.
  3. There are two kinds of die heads for plastic pelletizing machine: electric die head and hydraulic die head. The hydraulic die head can change the filter screen without stopping. It is more suitable for the material with more impurities, but the cost is higher correspondingly.
  4. The heating mode of the plastic pelletizing machine is divided into the cast aluminum heating ring, quartz tube heating ring, ceramic heating ring, and electromagnetic heating ring. The heating effect of electromagnetic heating is the best, the temperature can be added quickly and the effect of constant temperature is good, but it is not suitable for processing foam material. The heating method can be comprehensively considered according to the raw materials of the customer and the color of the final product.

Structure of the plastic pelletizing machine

This plastic pelletizing machine is mainly composed of a feeding port, screw press, press chamber, heating device, discharge port, mold head, reducer, machine body, base, motor, and other parts.

This plastic pelletizing machine is the main machine of the plastic recycling line and can handle a variety of plastic materials. But the machines that handle different materials are not exactly the same. Their appearance is similar, but the diameter of the internal screw, the distance between the screw and the barrel wall, and the length of the screw are all different. They all need to be adjusted according to the material. Therefore, one plastic film pelletizing machine cannot handle multiple materials.

How to operate plastic pelletizing machine

A plastic pelletizing machine is a machine for melting and extruding plastics of various materials. The following words we will introduce you how to operate it.

1. First, turn on the plastic granulator.

2. Secondly, observe the operation of the machine, and put it into use after there is no abnormal sound or vibration.

3. Before use, it is necessary to preheat the plastic film pelletizing machine so that it can melt the plastic. If the temperature is too high, the melted plastic will turn black; if the temperature is too low, the plastic will not melt.

4. Put the crushed material into the feeding port of the machine, and add a forced feeder for plastic film material to prevent the plastic pelletizing machine from not feeding.

5. The material melts in the squeezing chamber and is pushed out continuously along with the squeezing screw. The material from the main engine will enter the auxiliary engine again for secondary melting and extrusion.

6. The material from the outlet can be put into the cooling tank for cooling.

There are a series of plastic pelletizing machine available. The plastic film pelletizing machine type is named based on the screw length. There are also a different heating method for options. For special needs in terms of output, machine materials, etc, we can provide customization services.

Head dies of plastic pelletizing machine

The die head of the plastic pelletizing machine has three types, including an electric gear die head, hydraulic die head, and automatic slag filter. The function of the machine head is to transform the rotating plastic melt into a parallel linear motion so that the plastic melt is introduced into the mold sleeve evenly and smoothly, and the plastic is given the necessary pressure for molding.

Why choose this plastic pelletizing machine?

1. Reducer, die head, motor, etc. all use the highest equipment currently on the market.

2. The plastic film pelletizing machine can be customized according to customer requirements or raw materials that need processing. Such as the diameter of the screw press, the heating method, the die, the material of the screw press, the material of the machine, etc.

3. Rich production experience. There are many different plastic materials on the market. To process different types of plastics, changes need to be made inside the machine to achieve the best production results. There are many manufacturers who do not understand the material, and mistakenly believe that all the internal structure of the plastic pelletizing machine is the same. So that the machine-made seriously affects the output and quality of the final product.

Choosing a plastic granulator needs to collect much information and need patience, we hope you can get an ideal one.

What should we pay attention to in operation?

A plastic pelletizing machine is mainly used to recycle waste plastic film, PP, PE flakes. It is widely used in the waste plastic recycling industry and is deeply supported and favored by customers. However, in order to better ensure the overall performance of the plastic granulator and prolong the service life of the product, plastic granulator operation should be emphasized. What should we pay attention to when using a plastic film pelletizing machine? There is something we need to point out before operating the equipment.

How to match the plastic pelletizing machine?

The option of a plastic pelletizing machine is flexible, it depends on your quantity of raw materials and your budget. If your waste plastic does not exceed 100 kg, one main engine is enough for your granulation, you should put the head die on the main granulator. If you need to cope with over 100kg of plastic, adding two or three auxiliary engines is an applicable choice.

Granulation of plastic appliance shell

With the rapid development of modern industrialization, home appliances are also emerging endlessly. Due to the extremely high rate of replacement of home appliances, common home appliances include TV sets, refrigerators, computers, washing machines, etc. The high replacement rate of home appliances has led to a good prospect for the recycling of waste home appliance casings.
