The PDS Aluminum Flask is used for the injection of Thermal Plastics such as NaturaBlend Flexible Nylon and 4C Semi-Flexible Acrylic. 
Most flasks are cast making them porous this causes stone to easily stick to them, and significantly decreases the life of the flask. Our flask is milled from one piece of aluminum block,  creating an extra smooth finish. This, coupled with the special knock-out opening, makes opening your cases extremely easy and eliminates possible damage to the flask.

5" x 5" x 3" - Fits most leading injection units such as TCS and Thermodent
