From Sinsun's founding in 2006, we have grown into a leading Chinese fastener manufacturer. Explore our journey of expansion, integration, and engineering excellence.
Sinsun began with a singular focus in 2006: to build a factory dedicated to self-tapping screws. This foundational specialization established our core expertise from the ground up, cementing the unwavering commitment behind every fastener we manufacture today.
The year 2012 marked a pivotal step for Sinsun with the establishment of our Export Department. From that point forward, our specialized self-tapping screws and fasteners began reaching customers across the world, expanding our mission beyond borders.
In 2015, Sinsun expanded its control over quality by adding four spheroidizing furnaces for raw material processing and in-house wire drawing capabilities. This strategic upgrade moved our production beyond screw manufacturing, beginning with precise control from the raw material stage to ensure superior consistency and performance.
Our production capability was enhanced in 2018 with new German multi-station cold heading machines. Concurrently, we grew our product line to include a variety of drill tail screws, strengthening our specialized manufacturing foundation.
Sinsun's growth in 2021 was defined by two key metrics: reaching 36,000 tons in annual production and fulfilling international orders with over 1,100 export containers. This period underscored our capacity to deliver at scale to a global market.
To ensure timely delivery for our clients, we operate a 1,200-square-meter ready-stock warehouse as of 2023. This facility is dedicated to supporting efficient daily distribution and meeting your routine supply needs.
The addition of four heat treatment lines in 2025 significantly boosts our production capacity. This directly translates to greater consistency in product quality and stronger guarantees for on-schedule delivery, meeting your project needs with confidence.
At SINSUN, our quality control begins at the source. We start with premium raw materials from XING TAI Steel, then perform in-house spheroidizing annealing and precision wire drawing in our own plant. This end-to-end control, supported by our advanced drawing machines and gas-fired furnaces, ensures superior microstructure, consistency, and performance in every fastener and hose clamp we produce.
By leveraging our integrated German-engineered multi-station cold heading machines with precision Taiwanese production technology, we maintain dimensional tolerance thresholds down to ±0.02mm. SINSUN's advanced fastener manufacturing workflow involves rigorous stress-distribution testing and tailor-gripping processing, ensuring that no industrial component exits our doors without meeting global benchmark standards.
SINSUN operates four dedicated heat treatment lines, allowing for precise and controlled processing time to achieve consistent hardness (HRC 28-32) and enhanced product durability. This in-house capacity ensures both exceptional fastener quality and reliable delivery schedules, allowing us to manage high-yield industrial outputs without outsourcing delay vulnerabilities.
Additionally, our 12,000 sqm smart warehouse operates with an 18,000+ pallet capacity, optimized through computerized inventory management. This advanced warehousing integration enables SINSUN to easily fulfill OEM and ODM packaging demands, providing tailored packing, 3D design previews, and secure bulk logistics configurations to global partners with zero dispatch friction.
