Inside Penn-Union’s Foundry: Crafting High-Quality Electrical Components

At Penn-Union, our in-house foundry is a cornerstone of our manufacturing process, enabling us to produce high-quality electrical connectors and components with precision, reliability, and efficiency. By maintaining full control over our production, we ensure superior craftsmanship, consistent performance, and faster lead times for our customers.

The Foundry Process: Precision in Every Pour

The Penn-Union foundry utilizes advanced induction melting technology to heat copper to approximately 2,000°F (1,093°C), bringing it to a molten state ideal for casting. Once molten, the copper is carefully poured into precision-engineered molds to create components that meet strict quality standards. This controlled process ensures the durability, conductivity, and mechanical integrity of each part, making them well-suited for demanding electrical applications.

The Benefits of a U.S.-Based Foundry

In an era where many manufacturers rely on overseas production, Penn-Union’s U.S.-based foundry provides distinct advantages:

  • Supply Chain Reliability – Domestic manufacturing reduces risks associated with global disruptions, ensuring a more stable supply of critical electrical components.

  • Faster Lead Times – Without the delays of international shipping, we can deliver products more quickly, helping our customers keep their projects on schedule.

  • Stringent Quality Control – By keeping production in-house, we maintain strict oversight of every stage, from raw material selection to final inspection, guaranteeing superior product consistency.

  • Support for American Manufacturing – Investing in domestic production strengthens the U.S. economy and supports American jobs while ensuring compliance with industry and regulatory standards.
