What is blow molding machine? You may not have a particularly clear understanding, in fact, it is the equipment used to produce plastic products. Just like blow molding machines and injection molding machines, it is just another name, and it is also the collective name for this plastic production and processing equipment. Bekwell will use the next article to take you to learn more about the blow molding machine.
What is blow molding machine?
Simply put, a blow molding machine is a plastic machine used to produce plastic products. The equipment usually uses thermoplastics as raw materials, and processes and produces plastic products for different industries through a certain plastic molding process.
Classification of Blow Molding Machines
Blow molding machines are divided into the following three categories according to different production molding processes:
extrusion blow molding machine
Injection Blow Molding Machine
Stretch Blow Molding Machine
Why should we talk about the classification of blow molding machines first? Rather than the principle, because there are different classifications of blow molding machines, the working principles of different types of blow molding machines are also different. Therefore, Bekwell needs to tell you what the classification of the blow molding machine is first. As for the working principle of each classification, we will tell you separately in the following content to avoid confusion.
The working principle of the blow molding machine.
In general, the working principle of the blow molding machine is to heat and melt the plastic raw materials, and then output the heated raw materials to the mold through different plastic molding methods. The mold produces the corresponding plastic product.
What are the working principles of the three different types of blow molding machines?
extrusion blow molding machine Blow molding machine is to extrude the heated molten parison into the mold through the die for processing and molding.
Injection blow molding blow molding machine is to inject the processed raw materials into the mold through the injection system of the machine, like an injection, into the mold for molding.
The stretch blow molding machine is to stretch the parison laterally after it comes out, and then enter the mold for molding.
You should be able to find that the difference between these three different blow molding machines lies in the way the parison is formed.
How to choose a blow molding machine?
Among these three different types of blow molding machines, extrusion blow molding machines and injection blow molding blow molding machines are the most commonly used, and stretch blow molding blow molding machines are still relatively rare.
How to choose depends on the plastic products you want to produce. In general, extrusion blow molding blow molding machines are used to produce large multi-layer plastic products. For example: water tanks and buckets from several hundred liters to several thousand liters, plastic trays, mobile toilets, IBC ton buckets, chemical buckets, roadblocks, etc.
The injection blow molding machine is generally used to produce small plastic products, such as plastic bottles, cosmetic packaging, milk bottles and so on.
As for how to choose, in addition to the plastic products produced by yourself, there are other considerations for the selection of molding machines, which can give you some reference.
What is blow molding machine, including the classification, working principle and how to choose a blow molding machine? Bekwell will share it with you here. As a kind of plastic machinery, the blow molding machine has a wide range of specific functions and application fields.
