2K Molding
2k Molding is an injection molding method that uses two different plastic raw materials to produce a part. One plastic raw material is processed after the other within separate cavities in a single tool.
A-Plate
The portion of the mold that creates the outermost and cosmetic side of the part. It may also be called the “cavity” and does not usually have any moving parts within it.Additive manufacturing or 3D printing is a production technique that involves the manufacture of a physical 3D object by controlling the deposited materials to the print bed. The process is termed additive as the part is built by the 2D layers from the substrate to the ground up. The opposite is subtractive manufacturing.
An inclined pin is used in a plastic injection molding tool to actuate a sliding core block.
Gate
This is the part of the
mold where the resins enter to fill the mold cavity.
A consequence of insufficient ventilation, gas traps occur when there are
pockets of space in the part that trap gas during an injection molding
operation.
A triangular-shaped rib
feature is used to provide support to a part.
A set of digital programs
those are extracted from a 3D CAD file to instruct the machine on the tool path,
tool speed, feed rates, and other parameters when machine a CNC part.
Geometric dimensions and
tolerances are used to define geometric shapes of parts and components, to
define the individual characteristics of allowable deviations that may occur in
form and scale.
The time takes for the
molten plastic raw materials to fill a mold cavity before cooling and
solidification begin.
Height gauge
A measuring device used to
obtain the height of a part’s feature perpendicular to the horizontal plane.
This is a cylindrical drum
where plastic pellets (raw materials) are loaded to be melted for the injection
mold.
A hole in the injection
mold tooling that allows for the flow of materials from the nozzle to the mold
tool cavity.
Hot tip
Hydraulic-powdered sliding
cores in an injection molding tool
A thermopolymer plastic raw
materials are formed from a single monomer.
Hot tip gate is suitable
for product designs that allow small sprue residue on the surface or bottom of
the injector.
A heated channel system
used to supply the molten plastic resin from the nozzle to hot tip locations.
IGES
A type of CAD file format
for exchanging 3D data. The acronym stands for Initial Graphics Exchange
Specification.
The process of forcing the
molten material (thermoforming resin/molten thermoplastic) into a mold.
A plastic injection molding
processes involve the injection of molten plastic into a mold that contains a
pre-placed metal insert.
International Standards
Organization regulates consensus-based, industry-wide market acceptable standards
to govern raw material and production processes around a wide array of industries
and applications.
Jetting
The appearance of
serpentine curves on the molded product due to improper exit design. Jetting
usually occurs near a gate.
Knit lines
Nozzle
The final and desired shape
of the manufactured part. At this point, the part is ready for use and will not
undergo any further machining.
Quenching
The use of rapid cooling techniques to achieve material properties like hardness or solidity in a mold tooling operation.
Y-axis
One of the primary axes in a 3-dimensional X, Y, and Z plane. The Y-axis is usually the vertical axis depending on the point of view of the viewer.
