As industries move toward smaller, stronger, and more cost-efficient metal components, the role of a reliable sintered parts manufacturer becomes crucial. Powder metallurgy (PM) enables the mass production of gears, structural parts, locking components, and miniature mechanisms with stable tolerance and excellent performance—far beyond what traditional machining can accomplish at the same cost.

At XY-GLOBAL, we specialize in precision sintered metal parts, supporting automotive, consumer electronics, medical devices, and industrial automation.

This article provides real engineering data, production capabilities, and case studies, offering a practical guide for engineers evaluating sintering for their projects.

2. How Sintered Metal Parts Are Manufactured (Practical Summary)

Step 1 — Powder Preparation

Metal powders are mixed with lubricants.
Common alloys: Fe-2Ni, Fe-Cu, 316L, 17-4PH, 4605.

Step 2 — Compaction

Powder is compacted at 100–800 MPa into a green part.
Green-density uniformity determines later dimensional accuracy.

Step 3 — Sintering

The compact is heated in a controlled furnace at 1100–1360°C, where metal particles bond.

Step 4 — Secondary Processes (Optional but Common)

  • CNC machining for tight tolerances

  • Resin/oil impregnation

  • Heat treatment

  • Deburring/finishing

  • Infiltration for strength

This combination enables both economical mass production and precision performance.

Choosing the Right Ceramic Bearing Manufacturers What You Need to Know


3. When Should You Choose a Sintered Parts Manufacturer?

(Engineers love this section)

Choose sintering when your part requires:

✔ Medium–high volume production (10k–1M pcs)

✔ Complex geometry with internal features

✔ Small metal parts (0.3–80 g)

✔ Dimensional consistency across thousands of pieces

✔ Lower cost compared to CNC machining

Avoid sintering if the part is:

❌ too large
❌ requires 100% full density
❌ needs extreme impact resistance
