Can PET be used in extrusion blow molding?
Hey there,Blow molding is a manufacturing process by which hollow plastic parts are formed. In general, there are three main types of blow molding: extrusion blow molding, injection blow molding, and injection stretch blow molding. The blow molding process begins with melting down the plastic and forming it into a parison or in the case of injection and injection stretch blow moulding (ISB) a preform. The parison is a tube-like piece of plastic with a hole in one end through which compressed air can pass.- noizyoyster.com

What is the formula for manufacturing plastic bottles or containers for all purpose?
There is no formula. Plastic bottles are made from polymers such as Polyethylene terephthalate, (C10H8O4)n or Polypropylene, (C3H6)n, both of them are produced from fossil fuels products. These plastics are then used in processes such as extrusion blow molding, injection blow molding, and stretch blow molding, in order to make bottles or other containers.
How do blow ovens work?

What is the actual formula of blow up ratio?
The formula for blow-up ratio (BUR) is BUR = (D1/D2) where D1 is the diameter of the extruder screw and D2 is the diameter of the die in the blown film extrusion process. The blow-up ratio determines the amount of expansion that occurs in the film extrusion process.
