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 we produce.
We source premium wire rod exclusively from XING TAI Steel β a trusted supplier known for consistent chemical composition and metallurgical quality, forming the foundation of every fastener we produce.
Our four spheroidizing furnaces perform controlled heat treatment on wire rod, transforming the microstructure to achieve optimal ductility and formability before cold heading β a critical step for consistent fastener strength.
After annealing, wire is drawn to precise diameters using our in-house wire drawing machines. This tight control over wire dimensions directly ensures dimensional accuracy (Β±0.02mm) in the final fastener product.
At SINSUN, we combine German-engineered multi-station cold heading machines with precision Taiwanese production technology. Our specialized processes, including tail-gripping for drill screws, ensure every fastener is manufactured with utmost accuracy and consistency in our state-of-the-art production facility.
Imported German multi-station cold heading machines deliver high-speed, high-precision forming of fastener heads and shanks. This technology ensures consistent geometry and mechanical properties across every production run.
Precision Taiwanese rolling and threading equipment produces sharp, accurate thread profiles that meet international standards. Our thread rolling process work-hardens the fastener surface, enhancing fatigue strength.
Our tail-gripping process for drill tail screws ensures precise drill point geometry and consistent cutting performance. This specialized capability allows us to produce drill screws that meet the most demanding installation requirements.
SINSUN operates four dedicated heat treatment lines, allowing for precise and controlled processing time to achieve consistent hardness and enhanced product durability. This in-house capacity ensures both exceptional fastener quality and reliable delivery schedules.
Our advanced heat treatment systems support our end-to-end manufacturing control β from raw material to finished fastener β guaranteeing that every product leaving our facility meets the strictest international quality standards.
Continuous mesh belt furnace β precise temperature control for uniform hardness across all fastener types.
Added in 2025 β significantly boosts capacity and guarantees on-schedule delivery for large-volume orders.
