Injection Molding Machine
Notice the Hopper, and various mechanical hook-ups. The hopper is
typically fed via an air based material handling system (vacuum and or
air pressure).
|
Coolant Manifold and Connectors
Injection molds require coolant for efficient operation. Coolant
connecters are usually quick connect type. Color coding of the hoses
is usually Blue feed, and red or white return.
|
Sled or Injection Unit
The Sled contains the Hopper, and the entire plasticizing unit which
includes: rotating auger screw, barrel, and nozzle.
|
Nozzle and Band Heaters
The nozzle contains the final heating unit to control the melt temperature
before it enters the sprue.
|
Platens , Clamp Slots and Tie Bars
|
Stationary Platen and Locating Ring Hole
Typical locating ring hole is 4.00 DIA
This side of the press is typically referred to
as the "A" side of the press
|
Electronic Control Panel
The electronic controller, controls: Rate and amount of clamping force,
Injection time and speed, Ejection timing among many other features of the
press.
|
Movable Platen and Knock-out Bar Holes
Knock-out patterns differ by machine. This side of the press typically
is referred to as the "B" side of the press.
The movable platen delivers the Clamping Force to the Mold. It is guided by
the tie four bars.
