1. What Is Custom Plastic Injection Molding?

The custom plastic injection molding is putting the melted plastic into a metal mold. After cooling, open the mold and take out the solid plastic part.

Custom Plastic injection molding can use almost any type of plastic and resin. It means that we can use custom plastic injection molding to make different plastic parts of various sizes and complexity. Meanwhile, not every manufacturer can do so-called custom plastic injection molding for you. Beacause custom plastic injection molding requires highly advanced injection molding machines and strict quality control.

2. What Are the Advantages of Custom Plastic Injection Molding?

There are several advantages if you choose custom plastic injection molding.

  • Quick

custom injection molding is one of the most effective forming ways. The speed of injection molding all depends on the complexity of the molds. The more complex the mold, the more time is needed. And its production circle is very short–within 2 minutes. If the fabricators can produce more custom plastic injection molding parts, they would get more profits.

  • Flexible

There are a broad of materials suitable for custom plastic injection molding. You also choose any color for your parts.

  • Useful

Injection molding will do great help to make complex parts. It can manufacture millions of plastic parts consistently in a short time.

3. What Are the Differences Between Custom Plastic Injection Molding and Vacuum Casting?

Both custom plastic injection molding and vacuum casting are popular methods for plastic forming. There are some differences between the two of them.


  • Volume. Custom plastic injection molding is more suitable for large-scale parts with a shorter production circle. Meanwhile, vacuum casting is better for the small part, more complex, and a longer production circle. •Cost. The tooling cost of injection casting is more expensive than vacuum casting’s.
  • Tolerance. Injection molding can achieve smaller tolerance while vacuum casting can achieve a relatively normal tolerance.
