Product Selection Differences for Brass Inserts for Plastics Moulds

When selecting brass inserts for plastic molds, there are several key differences to consider among the available options:

1. Material Composition:

   • Brass inserts can vary in composition, with differences in the percentage of copper and zinc, as well as the addition of other elements such as lead or tin. The composition can affect the mechanical properties, corrosion resistance, and machinability of the inserts.

2. Thread Type:

   • The type of thread on the brass insert, whether it is external or internal, and the thread pitch should be considered to ensure compatibility with the plastic mold and the mating component.

3. Shape and Design:

   • The shape and design of the brass insert, such as hexagonal, round, or rectangular, can impact the ease of installation, torque resistance, and overall durability in the plastic mold.

4. Surface Finish:

   • The surface finish of the brass insert, such as smooth, knurled, or serrated, can affect the insertion force, pull-out resistance, and overall performance in the plastic mold.

5. Size and Dimensions:

   • The size and dimensions of the brass insert, including the outer diameter, inner diameter, and length, should be selected based on the specific requirements of the plastic mold design and assembly process.

6. Application Requirements:

   • Consider the specific application requirements, such as load-bearing capacity, temperature resistance, chemical resistance, and electrical conductivity, to ensure the selected brass insert meets the performance criteria of the plastic mold.

By carefully evaluating these factors and selecting the most suitable brass inserts for plastic molds, you can optimize the performance, longevity, and reliability of your mold assembly.
