What Is Plastic Injection Molding?

Injection molding is the most cost-effective method of mass-producing plastic parts. The injection molding process involves injecting molten plastic into a mold and ejecting the solidified part. This process can quickly be repeated hundreds or thousands of times, amortizing tooling costs and reducing the cost per unit to a few dollars or less. Since the injection molding process uses the same mold for each part, it provides consistent quality in every aspect. Injection molding also offers the widest range of materials, colors, appearances, finishes, and surface textures compared to CNC machining or 3D printing.

How Does Plastic Injection Molding Work?

The plastic injection molding process requires an injection molding machine, plastic raw material, and a machined mold. The plastic raw material is first melted in an injection unit and injected into a mold (usually machined from steel or aluminum), where it cools and solidifies into the final plastic part.

Advantages of Plastic Injection Molding

Plastic injection molding is the best option for mass-producing plastic parts. After all, there's a reason why so many manufacturing companies around the world use it to produce precision parts. NOBLE engineers summarize the following six advantages of using injection molding technology:

  • Efficiency

    The mold injection process is highly efficient, allowing large orders to be produced quickly.

  • Superior detail

    Injection molding is one of the most affordable ways to manufacture large quantities of parts, especially for bigger production runs. Even though designing and creating the mold can take time, the process then becomes very affordable and efficient.

  • Affordability

    Fast and efficient production ensures a low cost per part, while high production volumes produce further economies of scale. Aluminum, a cost-effective and readily available material, can be used for injection mold tools to control costs.

  • High-volume production

    Injection molding with steel molds can facilitate the production of parts in the millions.

  • High tensile strength

    Injection-molded parts may be reinforced by adding fillers into the liquid resin, improving tensile strength.

  • Ready-to-go finish

    With the proper treatment, injection-molded parts come out of the mold with a smooth finish that requires no further refinement.

UV absorbers Colorants
Flame retardants Glass fibers

Surface Finishes of Plastic Injection Molding

Injection molding includes injection mold tooling, plastic injection molding, and more. The surface treatment of the mold is usually completed during the production process. After the injection molding is completed, we will carry out certain surface treatments on the finished product as per your requirement.




A grade finishes are made using a diamond buffing process and yield shiny and glossy surfaces on injection molded parts.


B grade finishes use grit sandpaper to produce parts with a slightly rougher finish than grade A parts. Custom molded plastic parts that undergo B grade finishing have a matte surface texture.


C grade finishes use grit sanding stones to produce a rough, uneven surface. Injection plastic parts that undergo C grade finishing have a matte surface texture.


D grade finishes use grit and dry glass beads or oxide to produce a very rough textured finish. Depending on the type of material used, products can have a satin or dull finish.

Devin W --- Vice President

I worked with another Chinese machine shop for eight years, and while the relationship was initially great, I eventually became disappointed by quality issues, late delivery, and a complete lack of communication. So I decided to give NOBLE a chance with a small order. Not only did they deliver on schedule, but they also did it with 100% accuracy and attention to detail. It was the same with my next order. They have exceeded all my expectations: they are a pleasure to work with; they respond to my inquiries by the next day (often within hours) and do whatever it takes to meet my requirements. This is what working with a machine shop should be like.
