Korea-Indonesia Joint Venture
Connecting Korean engineering excellence with Indonesian production capabilities to manufacture high-conductivity copper and industrial steel materials.
Why global corporations trust PT Sungmin Metal Indonesia as their strategic B2B manufacturing partner.
We implement the exact technical systems, quality control, and management standards established in our Gimpo factory, Korea.
Our Copper Bus-bars achieve a superior conductivity rate of over 98% (IACS) with copper purity exceeding 99.95%.
Located strategically in Indonesia for direct international logistics support, linking Korea, Indonesia, and global markets.
Equipped with state-of-the-art smelting systems, continuous casting lines, and copper extrusion machines to support high-capacity, precise volume production.
From melting raw metal materials to producing precision copper slabs, billets, and bus-bars, we maintain a robust, sustainable closed-loop recycling ecosystem.

Global Partners
We heavily invest in advanced metallurgy and precision engineering to stay ahead of the curve.
Automated extrusion presses capable of processing massive billets into customized profiles with micrometer accuracy.
Advanced vertical and horizontal casting techniques ensuring zero porosity and uniform molecular structure.
In-house spectroscopic analysis and conductivity testing to guarantee 99.95% purity for every batch shipped.
Our commitment to the environment goes beyond compliance. We utilize advanced filtration systems to minimize emissions and a closed-loop water cooling system to conserve resources.
Copper is 100% recyclable without loss of performance. We actively re-integrate scrap materials into our production cycle, minimizing waste and promoting a circular economy.

For standard dimensions, we accept orders from 100 kg. For custom shapes, profiles, or special punching, the MOQ is typically 500 kg to 1 Metric Ton (MT), depending on the complexity of the extrusion die.
Yes, our manufacturing systems and products comply with ISO 9001:2015 for Quality Management, ISO 14001:2015 for Environmental Management, KS D 5530 (Korean Standards for copper bus-bars), and JIS H 3140 (Japanese Industrial Standards).
For standard products, order processing and shipment staging takes 1 to 2 weeks. For customized fabrications requiring extrusion dies, production takes 3 to 4 weeks, followed by transit times depending on destination (e.g., 5-7 days transit to South Korea or Singapore).
Absolutely. We have complete in-house CNC routing, bending, punching, and milling facilities. You can submit your technical drawings (.dwg, .dxf, or PDF) to our engineering team for validation and quoting.
We support standard B2B trade terms, primarily Telegraphic Transfer (T/T) with a 30% deposit and 70% against Bill of Lading, or Letter of Credit (L/C at sight) from verified global banks.
