Overmold Tooling System
What does the overmold tooling system look like and what are its
components?
1. The mold base is the mounting unit attached to the molding machine
plattens that holds the mold. There are many options in mold base
designs. Universal multi-unit dye (MUD) bases provide off-the-shelf
solutions to mold makers, including mold inserts for machining
cavity and mold sections. Because these MUD bases typically add
cost to the overall tooling system, many companies in the industry
design their own custom configurations that allow for a wider range
of mold sizes that can accommodate a range of molds at a lower
cost.
In vertical injection molding machines, the sprue bushing is where
the injection unit lines up against the mold and allows the molding
material to flow from the injection unit into the cavity. The
bushing should be made out of hardened tool steel and should be
replaceable because it can be subjected to millions of cycles
.
2. The "runner" is how the molding material is "funneled" through the
molds to get to the different cavities. The runners connect the
cavities together. Cold slugs or "runoffs" are essential to good
cosmetics and reduced scrap rates as they allow material to flow
without excess restriction caused by material cooling off within a
runner and causing restriction which, in turn, causes material to
be injected at higher pressures.
3. The loader bar is a section of the mold usually in one end of the
cavity that is lifted up either by hand or the machine to allow the
operator to insert a connector or terminated leads into it. Then,
the bar is retracted back into place and a new part is ready to be
molded.
4. The cavity is where the components are molded. Everything in a
cavity is important because it affects the way a finished part will
look: its shape, surface finish and size. Cavities can be aluminum
or steel, and be polished, textured or plated.
5. A wire shut-off, or "pinch-off," is the section of the mold that
pinches off on what is exiting the mold (typically wires) so that
the molding material does not cause material to flash outside of
the cavity. The fit and design of the shut-off are important. It
must be tight enough to not allow the material to flow out of the
cavity, but not so tight that it damages what it is shutting off.
Shut-offs should be removable so that they can be interchanged with
various sizes to accommodate varying cable diameters.
6. Knockouts are rods or pins that come up through the cavity or
loader bar sections to eject or push out the finished parts after
they have been molded. Knockouts usually leave residual impressions
in plastic parts and are used only if required.
