Reasons for powder metallurgy gears to produce pitting: 1. Gear overload: Powder metallurgy gears can experience overloading during long-term operation. 2. Gear oil shortage: During long-term operation, gears can suffer from oil shortages, leading to pitting issues.

The advantages of copper-based oil-impregnated bearings are that they are cost-effective, absorb vibration, have low noise, and do not require lubrication for long working hours.

The development trend of powder metallurgy products in the shipbuilding industry: Powder metallurgy products​ are applied to shipboard equipment, which operates in harsh conditions and has limited space for equipment replacement.

Automotive parts: In order to improve fuel efficiency and control emissions, the working conditions of automotive engines have become more severe. By using powder metallurgy valve seats, valve guides, VCT and chain wheels, high strength, wear resistance and heat resistance can be achieved.

In conclusion, finding a satisfactory powder metallurgy manufacturer is not easy, and it is important to consider various factors when making a selection. Harber Industrial is a well-known manufacturer in the industry with a strong reputation for reasonable prices, high-quality products

One of the characteristics of metal injection molding is that the injection feed requires the metal powder and organic binder to be mixed and granulated. However, the metal powder used for metal feeding and granulation is usually prepared by air atomization or water atomization. The preparation process of this powder itself will lead to a certain amount of moisture in the metal powder, so it is very necessary to dehumidify and dry the metal powder.
