Engineering Materials
Polymeric materials Processing of plastic materials Processing of Thermoplastic materials Blow molding- A method of fabricating plastics in which a hollow tube (parison) is forced into the shape of mold cavity by internal air pressure.
5
Engineering Materials
Polymeric materials Processing of plastic materials Processing of Thermosetting materials Compression Molding:- A thermoset molding process in which a molding compound (which is usually heated) is first placed in a molding cavity. Then the mold is closed and heat and pressure are applied until the material is cured.
