Metalurgi Serbuk

Metalurgi serbuk hemat biaya untuk komponen logam sinter yang kompleks

Ikhtisar

Metalurgi serbuk (PM) memampatkan serbuk logam dalam perkakas presisi dan mensinternya pada suhu tinggi untuk menghasilkan komponen padat near-net-shape. Proses PM kami ideal untuk roda gigi, bantalan, sproket, dan komponen struktural — terutama ketika geometri kompleks membuat permesinan menjadi tidak ekonomis.

Kami juga menawarkan Metal Injection Molding (MIM) untuk komponen yang lebih kecil dan sangat kompleks dengan sifat mekanik yang unggul. Volume produksi dari 5.000 hingga jutaan komponen per tahun.

Pertanyaan Umum

What is powder metallurgy (PM)?

Powder metallurgy is a manufacturing process that compacts metal powders in precision tooling and sinters them at high temperature to form solid, net-shape parts. It is ideal for high-volume production of complex components.

What materials are available for powder metallurgy?

We offer iron-based alloys (FC-0208, FN-0208, F-0008), stainless steel (316L, 304L), copper-based alloys (bronze, brass), and soft magnetic alloys.

What tolerances can powder metallurgy achieve?

Standard PM tolerances are ±0.05 mm. Secondary operations like sizing and machining can achieve tighter tolerances as needed.

What is the typical lead time for PM parts?

Tooling fabrication takes 3–5 weeks, and production runs typically ship within 2–3 weeks after tooling approval.

Can PM parts be heat treated or plated?

Yes. PM parts can undergo heat treatment, steam treatment, plating, and other secondary operations to improve mechanical properties and corrosion resistance.

What is metal injection molding (MIM)?

MIM is a variant of powder metallurgy for small, complex parts requiring superior mechanical properties. It combines the design freedom of plastic injection molding with the strength of metal.

What is the minimum and maximum production volume?

PM is most cost-effective for volumes from 5,000 to millions of parts per year. For lower volumes, we recommend evaluating alternative processes like CNC machining.
