Thermoforming process involves injecting of molten plastic into a mould cavity by application of compressed air.
View Answer Explanation
In thermoforming process, it is very difficult to control thickness of moulded parts or sheets.
In thermoforming, it is very easy to mould the plastic materials which are of crystalline nature.
Thermoforming is basically a cheap process as compared to injection and blow moulding process.
