1 Introduction
Powder metallurgy compensatory feeding is a common connection method in powder metallurgy production. It is characterized by simple configuration, uniform and accurately distributed filling components. It plays an important role in powder metallurgy production. In addition to the common powder metallurgy production method of powder metallurgy, powder metallurgy compensatory feeding method also has many special characteristics. For example, the particle size of the powdery material has a great influence on the strength of the powder metallurgy product.
In recent years, with the rapid development of powder metallurgy, powder metallurgy model design has made great progress. Many new models have come into being, which not only make the process more complicated and refined, but also make the product structure more reasonable. Moreover, the control of the powder metallurgy process becomes more refined and effective.

2.1 Powder metallurgy compensatory feeding
Powder metallurgy compensatory feeding is a method of connecting powder metallurgy materials. The powder metallurgy materials are evenly combined and won by gravity. This method has the advantages of convenience in operation, good accuracy and high production efficiency. It is widely used in powder metallurgy production.
For example, the compensatory feeding method can be used to connect the three kinds of materials such as tungsten molybdenum powder with different particle sizes to form a powder metallurgy product. The three components are evenly combined and won by gravity. After the product is sintered, the strength of the product is not affected.
2.2 Powder metallurgy model design
With the rapid development of powder metallurgy technology, powder metallurgy model design has also made great progress. Many new and advanced models have come into being. In the production of powder metallurgy products, what kind of models can be used depends on the process requirements, costs, dimensions and other factors of the product.
For example, when producing a powder metallurgy product, a particle-coated model can be used. This model can be used to “coat” a thin adhesive coating on the surface of the powder metallurgy product, which can increase the strength of the product, enhance the adhesion of the product and improve its mechanical properties.

4 Discussion and analysis
4.1 Analysis of powder metallurgy compensatory feeding
Powder metallurgy compensatory feeding is a connection method widely used in powder metallurgy production. The advantages of this method are that the components are evenly combined and won by gravity, and the product structure is reasonable.
The strength of the powder metallurgy product is mainly affected by the particle size of the powdery material. The smaller the particle size, the greater the product strength. Moreover, the particle size affects the material loading capacity, which has a great influence on the sintering process and the quality of the product.
4.2 Analysis of powder metallurgy model design
With the rapid progress of powder metallurgy technology, powder metallurgy model design has also made great progress. The models used in the production of powder metallurgy products now vary greatly.
The models used in the production of powder metallurgy products can be divided into three categories: one is the compensatory feeding model, which has simple configuration and good uniformity; the other is the compact model, which is mainly used to improve the strength of the product; and the third is the particle coating model.
The choice of model determines the flow of the powder metallurgy process and the characteristics of the product. For example, when using the compensatory feeding model, the product will have a low strength and the material filling capacity will be affected. While for the compacting model, the product will have a higher strength and more uniformity; for the particle-coated model, the surface strength of the product will be greatly improved due to the coating process.
5 Conclusion
In summary, the powder metallurgy model design has a great influence on powder metallurgy compensatory feeding method, and the selection of the model should be based on the specific requirements of the product. The different models will affect the characteristics of the product, so the design of the powder metallurgy model must be carefully selected.
