Infiltration
Infiltration wicks molten copper into a sintered iron skeleton, boosting density, strength and machinability. Huaxiao delivers infiltration as part of our ISO 9001:2015 certified Powder Metallurgy capabilities — from rapid prototyping to high-volume production, with full dimensional inspection and material certification on every order.

What Is Infiltration?
Infiltration compacts metal powder in a die and sinters it to bond the particles, forming complex, near-net shapes in one press stroke. Huaxiao’s Infiltration is ideal for high-volume, tight-tolerance components.
Because the die defines the geometry, features like teeth, hubs and oil grooves are formed directly — with almost no scrap. We add sizing, coining and secondary machining to hit final specs.
Our Infiltration Capabilities
Backed by 15+ years of precision manufacturing experience and a vertically integrated workshop:
How Infiltration Works
From drawing to finished part, our Infiltration process follows four controlled steps:

- Secondary ops (sizing, heat treat, machining) in one flow.
Choosing the Right Infiltration Partner
Powder metallurgy wins on high-volume economy and near-net complexity. Huaxiao Parts produces custom sintered components — including sintered gears, sprockets and structural bushes — with minimal scrap and fast tooling payback. Features like teeth, hubs and oil grooves are formed in one press stroke, then sized, heat-treated and machined to final tolerance, all within our integrated PM flow.
What to consider when sourcing Infiltration:
- Material & alloy — Pick the grade that matches strength, weight and corrosion needs for your Infiltration parts.
- Production volume — We support 1-piece prototypes through 100,000+ production runs, amortizing tooling efficiently.
- Tolerance & inspection — Specify critical dimensions; CMM reports and material certs are available on request.
- Secondary operations — Machining, finishing and assembly are handled in one continuous flow.
- Certifications — ISO 9001:2015 with full traceability and inspection reports on every lot.
