Just to mention a few, the products created using this technology include fuel tanks, seat support for vehicles, flower pots and toy wheels. In fact, the commonness of blow molding has allowed engineers to try and create a variety of applications and designs, which resulted to multiple interesting uses. Most plastic containers on the market today that holds some forms of liquid has went through this process. As you can see, this plastic production method brought about a lot of production perks, such as quick manufacturing and high volume outputs, which means that we are able to produce a lot of plastic containers.
It is a revolutionary form of technology.īlow molding is said to have revolutionized the industrial sector by allowing companies to use it widely to meet consumers’ needs for plastic ware. here are the advantages and disadvantages of blow molding: List of Advantages of Blow Mouldingġ. However, there are also some drawbacks to it that we should be aware of to know whether it is best to employ for the betterment of all. Now, many plastic manufacturers use this method for the obvious benefits it brings. In the case of injection and injection stretch blow molding, these processes use a preform, which is a piece that already has a form beforehand. Once it has cooled and hardened, the mold would open up to eject the part. This material is then clamped into a mold and then blown by air, of which pressure will push the plastic out in order to match the mold. Basically, the extrusion blow molding starts with melting down the plastic and forming it into a parison-a rounded mass of molten material formed by rolling it immediately after being removed from the furnace, with its final form being a tube-like plastic that has a hole in one end that serves as a passage way for compressed air. In blow molding, hollow plastic parts are being formed through a manufacturing process that is generally categorized into three main methods, namely injection blow molding, extrusion blow molding and injection stretch blow molding.
