Machine Description

The Setter Injection Molding Machine is comprised of four main sections: the clamp unit, the
injection unit, the controls unit and the product handling unit is available for part removal.
• The clamp unit closes and holds the mold sections together during injection of molten
resin (from the injection unit) and opens the mold for part removal.
• The injection unit uses a two-stage injection system. The first stage, the extruder, uses a
screw to melt resin pellets and fill the shooting pot. The second stage uses an plunger
to push the molten resin from the shooting pot into the mold.
• The product handling unit picks up molded preforms from mold cores and provides
cooling before releasing the preforms onto a conveyor.
• The control unit is comprised of the electrical cabinet and the Human Machine Interface
(HMI). All functions of the machine are controlled by an industrial PC located in the
electrical cabinet. The Human Machine Interface (HMI) controls the operation of the
machine and operating functions. After the initial machine setup, the HMI can begin
automatic operation, and control the clamp, injection, and product handling units. The
HMI is attached onto the clamp unit.

Safety Gates and Doors
The machine is equipped with safety gates and doors that prevent access to the mold, clamp
and product handling areas. The gates and doors feature transparent panels for viewing the
production area and a series of limit switches for each that trigger an alarm when the gates
or doors are opened.

Purging the Injection Unit
Purging the injection unit removes any dirt, obstructions or processed material that can
affect production. The process is also used to transition from one color and/or type of resin
to another.
To plasticize and purge material from the injection unit, do the following:
