Record 3 1998-02-19

English

Subject field(s)
  • Plastics Manufacturing
OBS

... preplasticizing machine. Of the equipment in use today, 95% is preplasticizing; either with a reciprocating screw or a screw-pot. In a reciprocating screw the melted material is collected in front of the screw, which continues to move backward against a controlled pressure as more material is melted. The area where the melted material is collected corresponds to the pot in a two-stage machine. When the screw is pushed forward by the hydraulic injection cylinder(s), a check valve(nonreturn valve) is closed. At this time the screw and nonreturn valve act like a plunger.

Key term(s)
  • two-stage screw-pot injection-moulding machine
  • two-stage screw-pot injection molding machine
  • two-stage screw-pot injection moulding machine
  • two-stage screw-plunger injection-molding machine
  • two-stage screw-plunger injection-moulding machine
  • two-stage screw-plunger injection molding machine
  • two-stage screw-plunger injection moulding machine

CONT

La machine la plus utilisée est la presse à vis-piston. On parle alors de préplastification; en effet la vis assure ici deux fonctions : -fonction vis en tournant sur son axe : plastification de la matière de façon homogène, -fonction piston en avançant le long de son axe : matière poussée dans le moule par l'extrémité de la vis (qui joue le rôle de piston).

A diemaker's square is used to check the clearance angle on dies. The blade is adjusted to the angle of the workpiece by means of a blade adjusting screw. This angular setting must then be checked with a protractor. Another form of diemaker's square is the direct reading type which indicates the angle at which the blade is set.
