High Density & High Performance Powder Metallurgy

HPM, which stands for High Density and High-Performance Powder Metallurgy, is a cutting-edge process that can produce parts with densities comparable to those made by metal injection molding, using traditional powder metallurgy techniques. The precision and strength of these parts far exceed those of conventional powder metallurgy components, making HPM particularly suitable for manufacturing parts that require high strength and high precision.

Process Overview

Complementarity with Existing Processes:

Cost-Effective Alternative:
HPM can serve as a cost-saving replacement for parts traditionally made by forging, casting, and machining.
Strength Optimization:
HPM offers a solution for enhancing the strength of parts produced by current powder metallurgy processes.

Advantages Comparison:

V.S. Traditional PM
Increased density: 7.1 become 7.6g/cm3
Strength increase: >60%
V.S. MIM
Accuracy improvement
Cost reduction
V.S. Forging / Casting
Cost reduction
Process Capacity Advantage
High material utilization, energy saving, carbon saving

Characteristics of HPM

Higher Density

HPM parts have significantly higher density compared to traditional powder metallurgy components.

Precision

The gear precision of produced parts can meet the highest standards.

Enhanced Strength

Overall strength, including tensile strength, tooth breakage strength, and hardness, is noticeably improved over general powder metallurgy parts.

Cost Efficiency

Compared to parts made by forging, casting, and subsequent machining processes like gear hobbing, the HPM process is highly cost-effective.

Suitable Products

Small Gears and Metal Parts smaller than Φ30 x 30 x 15 mm and weighing less than 30g.

Applications

Vehicles

Home Appliances

Electric Motor
