Abstract
A dual nested plunger transfer molding system. The dual nested plunger transfer molding system, comprises: a transfer plunger having a piston chamber internally, co-axially, positioned, integral within the transfer plunger; and a co-axial plunger slidably and co-axially coupled to the piston chamber. The co-axial plunger comprises: a co-axial plunger piston end, and a co-axial plunger drive end at the opposite end from the co-axial plunger piston end. The dual nested plunger transfer molding system further comprises a piston disc coupled to the co-axial plunger drive end, the piston disc cooperating with the piston chamber to form a slidable pressure boundary within the piston chamber.
Claims23
Dual nested plunger transfer molding system, comprising, in combination:
- a transfer plunger;
- a piston chamber internally and co-axially positioned integral within said transfer plunger;
- a co-axial plunger slidably and co-axially coupled to said piston chamber, said co-axial plunger comprising:
- a co-axial plunger piston end;
- a co-axial plunger drive end at the opposite end from said co-axial plunger piston end;
- and
- a piston disc coupled to said co-axial plunger drive end, said piston disc cooperating with said piston chamber to form a slidable pressure boundary within said piston chamber.
A transfer molding system having a plurality of dual nested plungers, comprising, in combination:
- a plurality of transfer plungers;
- a plurality of piston chambers internally and co-axially positioned, integrally within each of said plurality of transfer plungers;
- a plurality of co-axial plungers slidably and co-axially coupled to each of said plurality of piston chambers, each of said plurality of co-axial plungers comprising:
- a co-axial plunger piston end;
- a co-axial plunger drive end at the opposite end from said co-axial plunger piston end;
- and
- a plurality of piston disc coupled to each of said co-axial plunger drive ends, each of said plurality of piston discs cooperating respectively with each of said plurality of piston chambers forming a slidable pressure boundary within said respective each said plurality of piston chambers.
A method of using a co-axial dual nested plunger for the process of transfer molding, comprising the steps of:
- providing a transfer plunger;
- positioning internally and co-axially a piston chamber integral to and within said transfer plunger;
- providing a co-axial plunger slidably and co-axially coupled to said piston chamber, and further providing integral to said co-axial plunger:
- a co-axial plunger piston end;
- a co-axial plunger drive end at the opposite end from said co-axial plunger piston end;
- and
- providing a piston disc coupled to said co-axial plunger drive end, said piston disc cooperating with said piston chamber to form a slidable pressure boundary within said piston chamber.
