Online whole sale plastic injection molding parts custom ABS injection mold parts
Injection molding is the most commonly used manufacturing process for the fabrication of plastic parts. A wide variety of products are manufactured using injection molding, which vary greatly in their size, complexity, and application. The injection molding process requires the use of an injection molding machine, raw plastic material, and a mold. The plastic is melted in the injection molding machine and then injected into the mold, where it cools and solidifies into the final part.

What is plastic injection molding?
Injection molding is the most commonly used manufacturing process
for making plastic parts. Injection molding can be completed with a
host of materials, most commonly thermoplastic and thermosetting
polymers.
Injection molding requires an injection molding machine, plastic
raw material, and an injection mold. The raw plastic material is
melted in the injection unit and then “shot”/injected rapidly into
the mold under high pressure. The plastic material is cooled by
circulating water through the mold to transfer and remove the heat
from the steel mold, part solidifies as cooled, the mold opens and
the part is ejected from the cavity of the mold. The entire process
or “cycle” is completed in seconds and then repeated.
The key steps in injection molding:
1. Clamping: The mold’s two sides are sealed shut under hydraulic
pressure.
2. Screw Recovery: Plastic material is fed into the barrel and
conveyed via rotating screw down the barrel toward the front of the
screw. As the material is conveyed it is heated to the specified
melt temperature creating the “shot” or volume of material to be
injected.
3. Injection: Screw is pushed forward injecting the material under
very high pressure into the mold.
4. Cooling: Water circulated through channels in the mold to remove
heat and solidifies the molded part.
5. Ejection: The clamp releases, mold opens and part is ejected
from the mold.
Benefits of plastic injection molding
Plastic injection molding is ideal for producing high volumes of
the same object.
Parts can have complex geometries
Highly efficient and repeatable manufacturing processes
Automation means lower costs
Variety of material choices can be used
For injection molding, the products will be sent for 15 days. And we support OEM and ODM.
