A mixing process apparatus for discharging polymer material into a mold comprising a resin passage having an inlet for receiving polymer material and an outlet for discharge polymer material for molding, a first and second chamber communicates with said passage with each of said first and second chambers having a variable volume, said variable volume varying from a fill position for holding a predetermined volume of said polymer material to a discharge position for emptying polymer material, said first and second chamber being adapted for movement to transport said polymer material from a first mix position where one chamber is in a fill position and the other chamber is in an emptying position to a second mix position wherein said one chamber moves to an emptying position and said other chamber moves to a fill position, said first and second chamber being adapted for discharging said polymer material for molding when each of said chambers is in an emptying position.
A mixing apparatus for discharging polymer material into a mold comprising a resin passage having an inlet for receiving polymer material which inlet has a source heated polymer material under pressure communicating with said inlet and an outlet for discharging polymer material for molding, a first and second chamber communicating with said passage, each of said first and second chambers having a variable volume, said variable volume varying from a fill position for holding a predetermined volume of said polymer material to a discharge position for emptying polymer material, said first and second chambers being adapted for movement to transport said polymer material from a first mix position where one chamber is in a fill position and the other chamber is in an emptying position to a second mix position wherein said one chamber moves to an emptying position and said other chamber moves to a fill position, said first and second chambers being adapted for discharging said polymer material for molding when each of said chambers is in an emptying position.
A modular mixing apparatus connected directly to an injection molding machine comprising a resin passage having an inlet for receiving polymer material which inlet has a source heated polymer material under pressure communicating with said outlet and an outlet for discharging polymer material for molding, a first and second chamber communicating with said passage, each of said first and second chambers having a variable volume, said variable volume varying from a fill position for holding a predetermined volume of said polymer material to a discharge position for emptying polymer material, said first and second chambers being adapted for movement to transport said polymer material from a first mix position where one chamber is in a fill position and the other chamber is in an emptying position to a second mix position wherein said one chamber moves to an emptying position and said other chamber moves to a fill position, said first and second chambers being adapted for discharging said polymer material for molding when each of said chambers is in an emptying position.
