How Do Powder Metallurgy Parts Impact Part Quality?

Many plastic molding manufacturers use metal-forming applications to manufacture different products. Commonly used metal parts are cold-headed for in-mold assemblies, stamping, and machining. However, they fail to realize the potential of powder metallurgy. When you are planning to create a customized part for your plastic and metal component assembly, nothing can beat the potential and performance of powder metallurgy parts. 

·       Will parts made out of powder metallurgy support industrial lightweight demands?

In the last few years, the demand for powder metallurgy parts in the mold assembly designs has increased a lot. In comparison to the other metal parts, the PM parts are 10 to 15 % lighter in weight. So, when you are looking for a solution, i.e., lightweight without sacrificing the structural strength of the product, PM parts are a perfect choice.

With a wide range of blends and additives, these parts can be customized to suit any need. Once customized, they can be integrated easily. Whether the PM parts are plastic over-molded or metal insert molded, they are strong, durable, and extremely light. 

·       What are the advantages of PM parts over other metal components?

The powder metallurgy process, in comparison to the others, offers a number of advantages. We have discussed some of the vital ones below:

1.      This process offers a uniformity that ensures better product quality,

2.      Since it has a versatile application, it can be used in almost any industry,

3.      It is a cost-effective solution because it consumes less energy and offers higher metal utilization, better production speed, and limited secondary operation requirements. 

4.      In comparison to other materials, PM offers better compressive limits, which has a direct impact on the part cost and performance. 

·       How will you know whether the PM parts will be ideal for your requirements?

In order to get the best results out of the PM parts, you need to be aware of the fundamentals of powder metallurgy parts. For plastic over molding or metal insert mold assemblies, consider the following:

1.      What temperature will the part be subjected to during the in-mold process?

2.      What are the design considerations for the component assemblies?

3.      What are the load requirements of the application, and have you identified the wear points?

·       Temperature considerations

Since the sintered metal parts are porous by nature, you need to add oil to the bearings to enhance their overall durability and corrosion protection. You may also need to oil the PM parts to protect them from corrosion. In such a scenario, it is essential to know the application’s temperature so that the flash point of these operations is accurate for the assembling process. Thus, it is recommended to check the temperature to ensure that it does not affect the dimension of the chosen component.

·       Load and wear considerations

Whether you are using PM parts in creating an overmold or insert mold, these parts bond with plastic to provide structure, support and durability. These parts offer extra material strength to enhance the performance of the mounting points. 

·       Do your metal parts have the powder conversion potential?

If you are using a non-PM component, you may want to consider a conversion. However, for that, you should consult a PM expert who will be able to review the materials and consider the assembly and application requirements before suggesting the conversion. 

Final words:

The PM parts are way better than the other component parts available. When you are interested in a cost-effective solution, there is no other alternative. To purchase these parts, always consider a reliable manufacturer and dealer. Don’t settle for any run-of-the-mill PM manufacturing companies. You don’t want to compromise on the overall quality and performance of the product.
