How much can a small nut contribute to quality improvement and cost reduction? If you pay enough attention to it, you can certainly make it “shine and appreciate in value”!
The stainless steel embedded nuts used in radomes, with an annual consumption reaching hundreds of thousands, are as small as a finger joint. Yet, they are critical load-bearing points for the long-term safety and stability of the product’s overall structure. Their strength and corrosion resistance directly impact the product’s service life in harsh environments such as coastal areas and remote islands. In 2022, following the company leadership’s call for a “comprehensive improvement in product lifecycle reliability,” the Procurement Department, in collaboration with the Technical and Quality Departments, targeted a small embedded nut as a breakthrough, achieving a dual victory in “quality enhancement” and “cost reduction & efficiency improvement.”
Material Upgrade: Previously, the industry commonly used 304 stainless steel for embedded nuts. Based on practical stress analysis and corrosion environment data, the Technical Department precisely defined the material standards and mechanical performance thresholds. Aligned with customer expectations for product corrosion resistance and reliability, they conducted targeted testing and verification with the Quality Department. Ultimately, the decision was made to upgrade the material from 304 stainless steel to 316L, which offers higher mechanical performance and corrosion resistance. This upgrade increased tensile strength by 9%, elevating product structure and anti-corrosion performance to a new level.
Collaborative Breakthrough: Technical personnel went directly to the production frontline of manufacturers. Together, they explored methods to improve manufacturing precision, optimize structural design, and enhance processing efficiency. By shifting from serial processing (turning, rolling, drilling, tapping, cutting) to parallel operations, they not only reduced workpiece handling time and material loss but also improved coaxial accuracy, significantly lowering processing costs and successfully creating room for cost reduction.
Supply Chain Optimization: The Procurement Department delved into the upstream supply chain. By introducing competition and signing medium- to long-term procurement agreements, they secured a stable source of high-quality materials while achieving a disruptive reduction in costs. Currently, the upgraded 316L embedded nuts are applied across Topfrp Company’s full range of radome products. Over the past three years, this initiative has cumulatively saved over one million yuan in costs, realizing the “value appreciation” of a small nut.
The successful upgrade of the stainless steel embedded nut is a classic example of Topfrp’s systematic promotion of technological and management innovation, thoroughly implementing the philosophy of quality improvement and efficiency enhancement. Moving forward, Topfrp Company will continue to focus on technological optimization and supply chain integration, committed to providing customers with products and solutions of higher “cost-effectiveness.” This will tangibly help customers enhance product competitiveness and market adaptability, achieving mutual benefit, win-win outcomes, and shared growth with clients.
