In many industries—outdoor gear, luggage manufacturing, protective clothing, and technical equipment—the smallest component can determine the overall performance of a product. One such component is the waterproof nylon interlocking zipper. While zippers may seem simple, poorly designed ones often lead to leakage, corrosion, or premature failure, especially in wet or harsh environments. Manufacturers and product designers frequently struggle with problems such as water penetration, reduced durability, and unreliable sealing.

As the New Year approaches, we would like to take this opportunity to sincerely thank all our valued customers and partners for your continued trust and support throughout the past year.

In traditional zipper production, nylon zippers must be manually paired, marked, and sorted, which increases labor costs, production times, and the risk of defects. For many factories, this limitation is a major obstacle to the transition to automated sewing lines and mass production. But now TRC developed nylon interlocking zipper, a solution specifically designed for efficient, stable, and automation-friendly zipper production.

Our company's abbreviation is TRC, which stands for Top · Reliable · Continuous, a philosophy that guides our daily operations and long-term development as a professional zipper manufacturer.
