How sintered structural parts affect industrial machinery manufacturing

Efficiency and sustainability in production

The sintering process for structural parts is a direct response to industrial priorities for efficiency. It uses a near-net-shape manufacturing method. This approach helps original equipment manufacturers reduce material waste significantly. It also improves spart reliability and maintains cost stability. One industry analysis notes this makes it an environmentally friendly choice when compared to traditional machining, which typically involves subtracting material from a larger block.

Standards for consistency and quality

Recent developments in industry standards provide clearer metrics for these components. ASTM International Committee B09 on Metal Powders and Metal Powder Products has released new standards. They are ASTM B962, Test Methods for Density of Compacted or Sintered Powder Metallurgy Products Using Archimedes’ Principle, and ASTM B963, Test Methods for Oil Content, Oil-Impregnation Efficiency and Interconnected Porosity. These standards, developed by Subcommittee B09.04 on Bearings, offer manufacturers consistent ways to verify material properties.

Demands for strongness and reliability

In sectors like construction machinery, the requirements are strict. strongness, durability, and reliability are non-negotiable. Self-lubricating steel-backed sintered bearings with solid lubricant have become a preferred choice here. They help ensure machinery runs smoothly. Continuous innovation in metal iron sintered materials drives the development of more advanced sintered bearing products for this market.

Technical development and future applications

The technology's scope is expanding. Industry research points to several development areas. These include sintering of machine parts which require high strength and the development of light and compact sliding bearings as an alternative to rolling element bearings. Product development for industrial and automotive industries applying magnetic material technologies is another active field. The reliability proven in high-volume automotive applications, where sintered metal is described as 'everywhere' in components from gears to wiper motor bearings, informs its use in heavy industrial settings.

We provide sintered structural parts and bearings that meet these evolving industrial demands.
