In order to produce hollow objects, the most important technique used is known as blow molding. Like injection molding, blow molding is also considered to be an effective procedure and large numbers of products with hollow in the middle can be produced. A blow molding machine is used for this purpose by means of which the middle of the object can be left hollow and the molten material is placed into the mold cavity. High level of pressure and temperature is required in order to carry out the entire process effectively and efficiently.
Wide range of items can be made with the help of these machines ranging from bottles, cans, jars, containers, drums and even tanks. These products can be made in various shapes and sizes as per the specifications and requirements of the customers. Based on the blowing capacity of the machine, the size and the dimension of the product can be determined. Some of these are produced in full size, while some of these are produced only as parts to be used in other items.
There are again three main types of blow molding machine, and the mechanisms involved in these machines include the blow injection molding, extrusion blow molding and stretch blow molding. It is rightly up to the manufacturer to decide the kind of machine that he wants to use for manufacturing the finished product. In any case, the plastic is melted and blown into the mold with hollow in the middle. Compressed air is made to pass through the mold.
