Investigation
The raw materials for the production of plastic parts are used in different forms, one of which is granule. Granules or fine polymer grains used to make plastic parts are one of the most common types of raw materials. These materials are converted into plastic parts by various machines, and each of these machines produces parts in its own way. In the meantime, some machines are specifically designed to work with thermoplastic granules, which allow plastic parts manufacturers to mass produce their desired parts with the lowest cost and waste of raw materials. These specialized machines, known as granulators or extruders, can take you several steps forward in the process of producing integrated plastic parts and turn your production process into the most profitable type of production by eliminating additional costs.
What is a granule maker and what is it?
In simple words, the granulator or extruder is a device that is mostly used in recycling plastic materials and can make them into new shapes and sizes by receiving various plastic materials. The operation of this machine is not so complicated and if you take a closer look at a granule machine, you will find that this machine also has a barrel and cylinder system like an injection machine, and you can add many different materials such as metal rods, plastic, rubber, dry powder. And even food, get a sheet product or with different shapes.
In this way, you enter your raw materials, which are often in the form of granules or so-called granules, into the machine, and after melting them, the granule machine enters the desired molten material through small channels into its special molds and it makes it into the desired shape. After the initial molten material is formed, the machine will deliver it to you in the form of a piece with a new device.
Granules
The granulator machine is different according to the type of materials used and the design of the machine. For example, if we want to make the design of the device a criterion for its classification, in general, the types of granule devices are divided into two groups: single screw and double screw. The single-screw granule machine is used for pumping a large volume of materials, and the two-screw machine is more suitable for mixing and mixing materials. But when it comes to the plastic industry, these design categories give way to the lens and thread granule making machine, which will definitely confuse you, so in this section, we will introduce the types of plastic granulating machine based on consumables:
- HDPE pipe production machine: This type of granule making machine uses high density polyethylene (HDPE) granules to produce HDPE pipes that are used in agriculture, water and gas pipelines, fire fighting system, etc. is placed This machine receives HDPE granules and cools them in tubular molds after melting.
- Plastic sheet production machine: This granule production machine produces plastic sheets using raw plastic, which can be composed of various polymers. These sheets are used in various industries depending on the type of polymer.
- Film blowing machine: This machine turns polyethylene granules into plastic membrane. The plastic membrane produced in this granulator can be used as plastic covers and disposable membranes in agricultural and industrial packaging.
- Raffia Tape Stretching Machine: This granule making machine is exclusively used to produce packaging components. By receiving plastic granules, this machine transforms them into various packages such as chemical fertilizer packages, waterproof packages for cement, rice and chemicals.
- PET Box Strapping Production Machine: This machine produces functional belts using polypropylene granules. These plastic belts are used for the production of hand fasteners and manual and machine thermal insulation.
The benefits of granules
Using a granule machine has many advantages for the plastic industry:
- Low cost: granulation machines are more economical and less expensive than other plastic molding machines. This low cost is due to the efficient production process of parts with this machine.
Because all these devices use thermoplastic polymers to produce plastic sheets or tubes, which reduces the rate of waste of raw materials. The waste generated in the production process in this way can be used again as other production raw materials, which means reducing the cost of raw materials.
On the other hand, barring unexpected breakdowns and the end of the machine's life, granulators provide you with 24/7 availability, which allows you to always have a product to sell and avoid the exorbitant costs of product shortages. .
- Flexibility: Granule machines use a fixed cross-section to mold plastic products, which increases flexibility in product design. To imagine this constant cross-section, you can imagine a round cheese mold, with each cut a triangular shape is obtained.
The granulator works in the same way and because of this fixed cross-section, it can create complex shapes. However, a very slight change in this cross-section allows you to create a variety of shapes and designs.
This makes the granulator machine a suitable device for the production of plastic sheets and other parts and allows manufacturers to create composite features.
- Making it possible to change after molding: usually the plastic coming out of the granule machine is not completely cool and still has enough heat to apply changes in appearance. This issue allows manufacturers to manipulate the produced plastic by using various tools such as molds and rollers and create different shapes in it. This possibility makes the production of various plastic parts simple for plastic factories and prevents production-related errors.
Pricing
The price of the granulator depends on many factors, and the more features the device has, the higher the price. For example, the volume of each device is different from the other, and the higher the capacity, the higher the price. The type of alloys used in this device, the presence of gassing and mixing systems, as well as whether the device is simple or advanced, are all influential in determining the price of the granulator, so it is better to find the most suitable device before buying this device, according to experts in this field. Choose the granule according to your production needs.
