Extrusion blow molding is a highly versatile manufacturing process and it is used in many different industries. It allows you to create a product that has a uniform cross section. It seems unlikely that the same process that gives us candy canes and drinking straws also forms PVC pipe and automotive hoses, but it does. Using different materials, extrusion blow molding can produce an astonishing variety of products.
How Extrusion Blow Molding Works
Plastic extrusion molding uses thermoplastic pellets. The pellets are placed in a hopper and moved along to the heated barrel where they are melted. The melted thermoplastic is then forced through the die, which is shaped like the intended finished product. The result of this process is a continuous, long part that can then be cut into any size desired.
Advantages of Extrusion Blow Molding Plastic Products
The advantages of extrusion blow molding plastic products are far too numerous to mention, but among the most important is the low production cost. The cost is so low because the initial setup takes very little time and is very inexpensive. In addition to this, the process itself is amazingly efficient. On top of an already minimal production cost, there is very little waste produced during manufacturing, which brings the cost down even more.
The lack of excessive waste is due to the fact that the nature of thermoplastics allows any waste that accumulates to simply be melted down and used again. Not only does less waste mean lower material costs, but it puts less stress on the environment as well; both in landfill space and the raw materials used to produce the thermoplastics.
