Overview

Powder Metallurgy (PM) is a highly efficient metal forming process that transforms metal powders into precision components through controlled pressing and sintering. Yujiaxin Tech operates state-of-the-art PM presses with capacities up to 500 tons, capable of producing parts weighing from a few grams up to 5 kg. Our PM process achieves material utilization rates exceeding 95%, making it one of the most cost-effective manufacturing methods for medium to high-volume production. We produce parts with tolerances of ±0.05 mm to ±0.1 mm and offer controlled porosity options from 5% to 15% for specialized applications such as self-lubricating bearings. With typical production rates of 10-30 parts per minute and tooling lead times of just 3-5 weeks, PM offers rapid time-to-market for automotive, industrial, and consumer applications. Secondary operations including heat treatment, steam treatment, and impregnation are available to enhance part performance.

Frequently Asked Questions

What is the typical density range for PM parts?

Powder Metallurgy parts typically achieve 85-95% of theoretical density. The density can be controlled by adjusting compaction pressure, sintering temperature, and powder characteristics.

Can PM parts be heat treated?

Yes, PM parts can undergo various heat treatment processes including carburizing, nitriding, through-hardening, and induction hardening to achieve desired mechanical properties.

What is the maximum part size for PM?

PM can produce parts up to approximately 5 kg, limited by the press tonnage capacity and powder flow characteristics. For larger parts, alternative processes such as investment casting may be more suitable.
