Professional Powder Metallurgy Manufacturer

Working with Yeh Sheng Powder Parts is like working with an experienced partner. Since 1984, we have evolved from a specialized workshop into a premier international powder metallurgy (PM) manufacturer. We specialize in high-efficiency production of precision metal components, providing cost-effective, high-volume solutions for the most demanding modern industries.

Advanced Components for Robotics & Drones

As global industries shift toward automation, Yeh Sheng provides the critical backbone for Emerging Tech sectors. Our powder metallurgy process is uniquely suited for producing the complex geometries required in robotics and unmanned systems.

Robotic Arm & Automation Parts

Precision and reliability are the core of Robotics. We manufacture components that allow robotic arms to move with consistent accuracy and mechanical reliability.

  • Integrated Gear Design: We produce spur gears, planetary gears, and cams that are often too complex or expensive to produce individually through traditional CNC machining.
  • Self-Lubricating Bushings & Bearings: Our oil-impregnated powder metal parts provide built-in lubrication, an essential feature for joints in industrial robots to reduce maintenance and wear.

Drones & UAV (Unmanned Aerial Vehicles)

In the UAV industry, efficiency and consistency are the keys to successful mass production.

  • Complex Propulsion Parts: We produce motor rotors and small-scale drive components with high dimensional consistency.
  • Consolidated Part Design: By utilizing the "net-shape" capability of PM, we can combine multiple features into a single part, simplifying your assembly process and optimizing material usage.

High-Efficiency Gear & Transmission Solutions

Gears are the heart of any mechanical system. At Yeh Sheng, we offer a strategic advantage in Custom Gear Manufacturing for applications that require high volume and high precision.

  • Geometrical Freedom: We can easily produce gear shapes—such as combination gears, eccentric gears, and non-standard tooth profiles—that would be difficult to cut on a traditional hobbing machine.
  • Cost-Effective Mass Production: Our process is ideal for gears used in small appliances, hand tools, and light-duty automation where cost-efficiency and reliable performance are required.

Technical Advantages of Yeh Sheng

Why do leading global brands partner with us?

Material Versatility

We offer a wide range of iron-based and alloy-steel powder formulations to tailor hardness and wear resistance to your specific needs.

Near-Net Shape Efficiency

We minimize material waste by pressing powder directly into the final shape, significantly reducing secondary machining and total cost per unit.

Decades of Expertise

Since 1984, we have helped our clients solve technical challenges by thinking outside the box and applying innovative metallurgical methods.

Our Philosophy: Continuous Improvement

We may not be the number one, but we are a company that strives to improve ourselves daily. At Yeh Sheng, we don't just supply parts; we provide solutions. We welcome each challenge the future may bring and are committed to delivering the satisfactory, high-quality results your business deserves.
