ABSTRACT:
A multifunctional assembly for use in various plastic forming processes includes a housing conformed for selective partition to receive an incandescent light assembly as a source of heat and selectively positioned pneumatic cylinders for compressing heated plastic into forms and extrusion dies. An air pump selectively connected by manifolds may then be used for generating vacuum and pneumatic pressure both for the forming processes and for the pneumatic cylinders.
