| A
principal process for manufacturing custom plastic parts
or components, thermoplastic injection molding involves
taking thermoplastic material in the form of pellets or
grannuals and heating the material until a melt is obtained.
The melt is then forced into a split-die chamber/mold where
it cools to form the desired shape. The mold is opened,
the part is ejected, and the cycle is repeated.
Three keys to Aline's Plastic
Injection Molding Process:
High Quality Thermoplastic
Materials
As a plastic injection molding manufacturer, Aline Components,
Inc. offers one-of-a-kind thermoplastic injection molding
services. With a broad range of services, we can form just
about any thermoplastic material to your exact requirements.
Thermoplastics are materials that, once formed, can be continually
heated and reformed. Learn more about thermoplastic materials
available at Aline Components, Inc.
Custom Manufactured
Molds
Our molds are made from high quality metal, either
steel or aluminum, and precision-machined to form the features
and characteristics of the specified plastic part or component.
Aline provides some of the finest standard and custom molds
available today with fewer moving parts that results in
reduced maintenance and repair costs. Click

Advanced Injection
Molding Machines
Aline Components houses a complete line of automated
equipment in which the entire thermoplastic injection
molding process takes place. Our machines are comprised
of two basic units: the injection unit melts the plastic
then injects or moves it into the mold and the clamping
unit holds the mold shut during filling. The two units
work together as follows:
First, the thermoplastic material is put into
a hopper where a reciprocating screw pushes the plastic
through a long heating chamber to reduce pelletized resins
and coloring agents into a hot liquid. At the end of this
chamber there is a nozzle which is positioned firmly against
the opening of the closed mold. Under tremendous pressure
the slurry or melt is forced through this nozzle into
a cooled mold. A system of clamps hold the mold halves
shut. Once the material solidifies, the mold is unclamped
and a finished part is ejected.
