Bronze Plating Facilities

Lamina's modern bronze plating facility uses automated rack plating. Our bronze plating operation provides a complete metal finishing service. We offer process services for chemical cleaning, aqueous washing, degreasing, and regular sand blasting.

Lamina specializes in the bronze plating of wear surfaces on low and high carbon steel. Our bronze plating line can accommodate single part weights up to 400 lbs. (180 kg) and a part size envelope of 36" x 36" x 96 " (900 x 900 x 2400 mm). Our bronze plating (80% copper 15% tin, 5% trace elements) process can attain a controlled plating thickness in the range of 0.001 to 0.025 inch (0.025 to 0.64 mm). Bronze plating hardness of 70 Rb can be achieved.

Lamina's Bronze Plating operations provides complete process control, quality, testing and chemistry for our in-house metal finishing and electroplating. Complete automotive, aerospace, military and commercial testing and approvals are available.
