PLASTIC PRODUCTION PROCESS - Coggle Diagram
PLASTIC PRODUCTION PROCESS
EXTRUSION
pass through a heated region of the machine
molten polymer extruded into dye
create parts of length and common used for pipes and window frames
BLOW MOLDING
inflating it within a mold using air pressure
cooling and solidifying the shape
forming a parison (tube of molten plastic)
PET BLOW MOLDING
injection molded
reheat and blow into final shape
bottle are created in test tube shape
INJECTION MOLDING
has applications with intricate shapes and high precision requirements
highly repeatable and precise
plastic is melted and injected into a mold cavity under pressure
WHEEL BLOW MOLDING
high volume production of bottles
heating, forming and cooling simultaneously
rotating molds around a wheel
BLOWN FILM
Air inflates the tube into a bubble, stretching it into thin film
molten plastic is extruded through a circular die to form a tube
The film is cooled, flattened and rolled for use
