          FZ Series Inserts

          The advantages:
          Injection molding.
          Straight knurling with groove design can provide strong torque and pulling force.
          Blind-end design can effectively prevent plastic backflow causing internal hole defects
          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.

          What is the best thread type for plastic?

          When choosing the best thread type for plastics, there are several factors to consider, including the type of plastic, the application, and the specific requirements of the assembly. Here are some common thread types that are often recommended for plastics:

          Unified National Threads (UNC/UNF): These are standard thread types commonly used in a variety of applications. UNC (coarse) threads are generally better suited for softer plastics as they provide a larger gripping surface area and reduce the risk of stripping.

          Metric Thread: Similar to UNC/UNF, metric threads are widely used and suitable for plastic applications. The choice of coarse and fine threads depends on the specific plastic and application.

          Self-tapping threads: These threads are designed to cut their own path in the material. They are particularly useful with softer plastics because they create a secure connection without pre-tapping.

          Helical Threads: These threads are often used on Inserts designed for plastics. They provide a larger surface area for engagement, helping to distribute pressure more evenly, thus reducing the risk of stripping.

          Knurled or buttress threads: These types of threads can provide extra grip in softer plastics, helping to prevent the insert from loosening over time.

          Notes:
          Material Properties: Softer plastics may be suitable for thicker threads, while harder plastics can accommodate thinner threads.
          Load requirements: Consider the mechanical loads the threaded connection will be subjected to. Coarse threads generally have better resistance to stripping under load.
          Installation method: The installation method (e.g. self-tapping, heat setting) will also affect the choice of thread type.

          The best thread type for a plastic depends on the specific application and material properties. Softer plastics are often preferred for coarse threads, while harder materials may be better suited for fine threads. When choosing the right thread type, be sure to consider the specific requirements of your project.
