          ITA- Inserts

          ITA- Series Inserts

          The advantages:   
          Injection molding embedding, available in aluminum, brass and stainless steel materials products
          Diamond knurled design can provide strong torque and pulling force
          Suitable for thermoplastic plastics and thermosetting plastics
           
          Installation instruction:
          Please put the threaded inserts into a reserved core pins, then closed the mold and mold it together with the plastic.
          The core pin is designed to match the bottom hole of the thread or be designed according to the size table.
          If the core pin is smaller, it will cause the platic overflow into the internal thread; if the pin oversize, it will cause the inserts failed put into.

          Critical Installation Instructions (Mold Design)

          The success of this insert depends entirely on precise mold design. The instructions highlight the most crucial factor: Core Pin Design.

          1. Process: The insert is manually or automatically placed onto a core pin inside the injection mold. The mold closes, and molten plastic is injected around it.

          2. The Core Pin's Vital Role: This pin has a dual purpose:

            • It positions and holds the insert in place during molding.

            • Its diameter plugs the insert's internal threads to prevent plastic from entering them.

          3. Consequences of Incorrect Core Pin Size (The "Goldilocks Principle"):

            • Pin is TOO SMALL: Plastic will overflow into the internal threads, requiring costly post-molding cleaning (re-tapping) and potentially damaging the threads.

            • Pin is TOO LARGE: The insert cannot be placed onto the pin, halting production.

            • Pin is JUST RIGHT: The insert fits snugly, the threads are perfectly protected, and a flawless part is produced.

          Pro Tip: The core pin diameter should match the minor diameter (root diameter) of the insert's internal thread, typically found in the manufacturer's technical size table.
