How Blow Moulded Product is Made?
Manufacturers can make a range of fine quality products with extrusion blow moulding. A maker can manufacture a variety of products as per requirements like bottles, jars, tubing, containers and many more with various sizes and shapes. The products are made with blow mouldings like water bottles, peanut butter jars, specimen jars and also bottles for cooking oil, shampoo and milk.
The single extrusion blow moulding machine produces products for technical, medical, food and beverage, consumer good and many other. The industry experts use this method for making for big plastic drums, storage tanks and many more.
There are two extrusion blow moulding processes one is continuous or intermittent parison process. In this method, the extruder runs continuously and parison. The second process uses an accumulator. In this process of accumulator head blow moulding, the extruder refills the accumulator for the next step.
Here is the guide to produce an extruded product by the continuous method.
- First, add the raw material to the hopper on the extruded blow moulding machine. And the operator also can add additives and colourants at that time.
- Next, the pellets or plastic beads travel through feed throat. Here the material enters into the barrel and there is a large rotating screw.
- And after that, the barrel heats up to melting temperature and the heat and rotation convert the material into gooey form.
- Now the material reaches to the end of the screw and flows over a screen and a breaker plate. There is mainly two use of this part. The screen part removes any contaminants in the plastic. And the breaker plate changes the motion of plastic from rotational to longitudinal. And the material is ready to die.
- The role of the die is to spread the plastic when it leaves from the cylindrical profile from the extrusion blow moulding machine. The die is important to produce a quality product.
As the consistency of the extrusion blow moulding machine, the manufacturer can produce a variety of product without losing the quality. And with this machine, they can make complicated products also.
