Fastener Barrel Plating Line

Our Fastener Barrel Plating Line is specifically engineered for high-volume zinc electroplating of standard fasteners including bolts, screws, nuts, washers, and metal stampings. This automated line combines rapid plating speeds with consistent quality, making it the preferred choice for fastener manufacturers and platers worldwide.

The acid zinc barrel plating process is particularly well-suited for low-carbon steel fasteners (grades 4.8 and 6.8), offering excellent throwing power into thread roots and head recesses at the lowest operating cost.
