Blow molding is a popular manufacturing process used for producing hollow plastic parts, such as bottles, containers, and other industrial products. To carry out this process, a special type of equipment is required, known as a blow molding machine.
Blow molding machine also known as hollow blow molding, is a kind of rapid development of plastic processing methods. A blow molding machine is a mechanical device used to transform various plastic raw materials, such as polyethylene (PE), polypropylene (PP), and polystyrene (PS), into hollow objects through the application of controlled heat and air pressure.
Blow molding machines are mainly composed of extruders, heads, hydraulic systems, clamping systems, electric control systems, pneumatic systems, and automatic clip parts, used for blowing PE and other hollow products of a variety of materials. Such as square barrels, round barrels, beer fresh containers, toolboxes, chimneys, etc. It is high-performance, low consumption and easy to operate. In the world of manufacturing, blow molding machines play a pivotal role in the production of various plastic products. From bottles and containers to automotive parts and toys, these machines enable manufacturers to create hollow plastic objects with precision and efficiency.
Simply put, the working principle of a blow molding machine produced by the blow molding machine factory is similar to blowing bubbles. After the plastic and the hopper enter the screw barrel of the extruder, they are pushed toward the head by the rotation of the screw thread. Due to the resistance of the filter, splitter plate, and head die at the head of the machine, as well as the gradually decreasing capacity of the screw thread, the advancing material encounters great resistance, while also being heated by the heat transmitted from the barrel. On the other hand, when the plastic is subjected to forces such as compression, shear, stirring, etc. during movement, friction between the plastic and the barrel, between the screw threads, and between plastic molecules will produce a large amount of heat. Since the temperature of the plastic inside the barrel keeps rising, its physical state gradually changes from the glassy state to the high elastic state, and finally becomes the molten state, further completing plasticization. As the screw continues to rotate, the molten plastic is extruded from the head die in a pressure-balanced and constant amount, forming a plastic product with a certain shape. After cooling and shaping, the extrusion molding work is completed.
There are several types of blow molding machines, each suited for specific applications:
1. Extrusion Blow Moulding (EBM): This is the most common type, suitable for producing bottles, containers, and drums. It uses a continuous extrusion process to create parisons.
2. Injection Blow Moulding (IBM): This type combines the injection molding process with blow molding. A preform is created using injection molding, which is then transferred to the blow molding machine for stretching and blowing.
3. Stretch Blow Moulding (SBM): SBM is commonly used for manufacturing PET bottles and jars, particularly for beverages and personal care products. It involves stretching the heated preform before blowing it into the final shape.
