Plastic Thermoforming

Hi , Finally we decided to make a final year project in Electrical Control as " Plastic Thermoforming Production Line " , I arranged the processes as follow :

1- a plastic sheet of 20cm * 20cm area and 2-3 mm thickness which will put on a half model
2- then , the plate which hold out the sheet will moved under heater with specified temp.
3-after heating process , the plate will moved under a hydraulic ( or pneumatic ) Piston which have the other half of the model ; Do you imagined ؟!!
4-after the previous process the plate will move under 3 axis C.N.C which will trim the unused part .
5-Finally, the plate will move under 1 axis pneumatic arm which will carried the final product - by Suction - to a box .

Questions :
1-What is your opinion of the whole idea ?
2- Is there any wrong process ?
3-For the piston , Which i use a hydraulic or a pneumatic ?

This video will explain which i means
