Manufacturing Processes for Polymer Components
Transfer Moulding
Blow Moulding
Extrusion
Thermoforming
Rotational Moulding
Calendaring
Injection Moulding
Used for Thermosets
Used to make bottles and containers
Shapes thermoplastics
A polymer tube is lowered into a mould, & air, forces the tube to shape the mould
Extruded to take shape of the die
Only suitable for Thermosoftening material
Tubing for bicycle cables
Polymer granules are melted and molten material forced into the die
Heated thermoplastic sheets are placed over dies to produce the required shape
Thermoplastic containers
A thermoplastic is poured into a cavity between two rollers & the plastic is squeezed through the rollers
Tiles, films and curtains
The molten plastic is poured into a mould & centrifugal forces throw the polymer to the walls of the mould, forming a hollow article
Molten polymer is injected into a cavity in the shape of the finished article and when solidifies, is ejected and procedure starts again
