7 Super Facts to Know About Custom Injection Molding


Injection molding has been a popular manufacturing process for many years. Injection molded parts are found in every home, business, and vehicle. Today’s custom injection molding process benefits from many breakthroughs that have resulted in a more predictable and cost-effective process and high-quality parts.

What is Injection Molding?

Injection molding is considered a critical backbone industry. Plastic is the most common material used. Pellets are automatically fed into the injection molder, melted, and injected into a mold. The cooled parts are automatically removed from the mold. Many small parts can be produced at the same time in molds with multiple cavities.

7 Super Facts About Custom Injection Molding

  1. Accurate to Within .005″
    Custom plastic injection molding can be used to manufacture almost any plastic part. Molds must adhere to certain design restrictions, but the finished products meet strict specifications.
  2. Speed
    Speed is the primary reason for the popularity of custom injection molding for long manufacturing runs. More complex molds can take a little longer, but there are normally only 15 to 30 seconds between cycles.
  3. Lower Costs
    Time is money, and the speed of the custom molding process is a real money-saver. Machining plastic parts can cost 25 times as much per unit as injection molded parts. Since most of the injection molding process is automatic, there are low labor costs associated with part production, which is another factor in the cost-effectiveness of injection molding.
  4. Efficient and Resourceful
    Anyone concerned about the environment should appreciate plastic injection molding. Only the necessary amount of plastic is used for each part. Any excess plastic (test or rejected parts) is ground up and recycled.
  5. Flexibility
    It’s easy to change the color or type of material being produced. It’s also custom made to your specifications.
  6. Enhanced Strength
    Fillers can be added to the plastic to enhance the strength of the finished part or add other desired characteristics such as flexibility or resistance to ultraviolet light.

  7. Smooth Finish Out of the Mold
    When the part comes out of the mold, there is very little or no finishing required. This is another factor in the low costs.
