CAPLUGS protecting cover

Caplugs was founded in Buffalo, New York in 1948; for nearly 60 years, caplugs has been a leading enterprise in the product protection industry. In 2003, the parent company of caplugs acquired Niagara caps & plugs, bringing the two industry giants together and providing the largest and widest range of product protection solutions. At present, the merged company boasts manufacturing plants in Buffalo, New York, Erie, Pennsylvania, and Los Angeles, California

We know that the needs of our customers tend to evolve and become more special; therefore, we recruit design engineers from various disciplines and focus on customizing product protection solutions for our customers. In a few weeks, these people can complete the component design, manual sample production, and production mold processing tools. By trying new material formulation and molding technology, we can get the most advanced product design and component manufacturing technology. Caplugs has positioned these people as the industry leaders
