What Are Limitations of 90WMoNiFe Alloy Cold Runner System?

Although the 90WMoNiFe alloy cold runner system has the advantages of high strength, high wear resistance and high corrosion resistance, it also has some limitations. Here are some possible limitations:

higher cost

90WMoNiFe alloy is a high-performance material that typically costs more than traditional cold runner materials. This may increase the manufacturing cost of the mold, thereby affecting the cost of the final product.

Difficult to process

Due to the high hardness and strength of 90WMoNiFe alloy, it is difficult to process. This may require higher-level processing equipment and more complex processing processes, thereby increasing manufacturing costs and time.

Pressure losses and temperature fluctuations

Cold runner systems inherently suffer from pressure losses and temperature fluctuations, which can affect the quality and performance of the final product. While the high thermal conductivity of 90WMoNiFe alloys can help reduce these problems, they may still not be completely eliminated in some cases.

Application restrictions

Due to the special properties of 90WMoNiFe alloy, it may not be suitable for all types of injection molding applications. For example, in some applications where rapid heating or rapid cooling is required, the alloy may not provide the required properties.

Maintenance and replacement costs

Although 90WMoNiFe alloy cold runner systems have high durability and service life, they may still require maintenance and replacement during long-term use. This can increase operating costs and downtime.

These limitations are not absolute and depend on application requirements and conditions. When selecting a 90WMoNiFe alloy cold runner system, its advantages and disadvantages as well as actual application requirements should be comprehensively considered to make the most appropriate decision.
