What are the benefits of using Sintering?

Sinstering Process

Sintering is an efficient metal forming technology to manufacture high precision components. This process can avoid, or greatly reduce, the need to use metal removal processes, thereby drastically reducing yield losses in manufacture and often resulting in lower costs.

Mixing​

Various types of raw powders are weighed in specific ratios, and then mixed by a blending machine to obtain a uniform mixture.Available Types of Materials : Wear/Heat Resistant, Anti-Corrosion, High Toughness, High Strength, Soft Magnetic.

Compacting

The mixed powder is placed in a high precision tooling, then compacted by a vertical press machine to form a compressed part called Green compact.

Sintering

The Green compact is placed into a sintering furnace, where  it is heated in gas atmosphere at temperatures below the  melting point of base metals. An alloy component of near  net shape is then ready for delivery or further processing.

Secondary Processes

The post treatments, such as repressing, machining and/or  heat treatment may be applied for increased precision or strengthening if necessary Available Types of Materials : Steam Treatment, Heat Treatment, Surface Coating, Sizing, Assembly, Oil Impregnation, Machining, Gear Rolling
