    Frequently Asked Questions (FAQ)


    How does the custom injection molding process work?

    The process involves designing a mold, melting plastic material, injecting it into the mold cavity, cooling and solidifying the part, and then ejecting the finished component. Post-processing may include trimming, assembly, or finishing.

    What industries use custom plastic injection molding?

    Custom injection molding is widely used in industries such as automotive, medical & healthcare, electronics, aerospace, consumer goods and industrial applications.

    What are the benefits of custom injection molding over other manufacturing methods?

    • High precision and consistency
    • Cost-effective for large production runs
    • Ability to produce complex geometries
    • Wide material selection
    • Scalability from prototype to mass production

    What is the typical lead time for custom plastic injection molding?

    Lead times vary based on design complexity, mold fabrication, and production volume. Generally, prototyping can take a few weeks, while full-scale production may range from 4 to 12 weeks.

    What is the lifespan of an injection mold?

    A mold’s lifespan depends on its material and usage. Aluminum molds are ideal for short runs, while steel molds can last for millions of cycles with proper maintenance.
