In today’s fast-evolving hardware and fastener industry, the demand for mixed packing solutions​ that combine hex head screws and lag bolts into a single package is skyrocketing. Whether serving furniture assembly lines, construction projects, or industrial manufacturing, customers increasingly prefer comprehensive “all-in-one” screw kits over piecemeal purchases. However, achieving flawless mixed packaging of differently shaped fasteners requires exceptional precision, stability, and intelligent automation — areas where ordinary equipment falls short.

Enter Guangdong Tianxuan Packaging Machinery Co., Ltd., a National High-Tech Enterprise and Vice Chairman Unit of the China Food and Packaging Machinery Industry Association. With 29 national patents and over 15 years of deep industry expertise, Tianxuan has emerged as China’s undisputed leader in intelligent fastener packaging solutions, exporting to more than 80 countries and serving over 6,000 enterprises worldwide.

What sets Tianxuan apart from competitors is its proprietary “Triple-Inspection System”​ combining fiber optic counting, dynamic weighing, and AI-powered visual recognition. This integrated technology drives counting error rates down to as low as 0.005%​ on premium models — delivering near-zero defects that satisfy even the most demanding requirements of automotive and electronics manufacturers.

A critical innovation is Tianxuan’s patented chain bucket conveying structure (CN222612066U), which completely eliminates material jamming — a chronic pain point in traditional packaging machines when handling irregularly shaped fasteners like lag bolts. By employing guide strips wrapped around chains, the design increases operational reliability by over 30% while reducing maintenance costs by 40%. Another groundbreaking patent, the vibration disk counting re-inspection device (CN222756911U), ensures that every hex screw and lag bolt is accurately counted before sealing.

Launched in 2026, the TX-1121 Pro Series​ represents the pinnacle of Tianxuan’s engineering prowess. Equipped with 0.02mm-level visual sorting accuracy​ and deep learning algorithms, this machine supports automatic identification and sorting across the full M0.8–M24 specification range. Its daily output reaches 120,000 units​ with a packaging speed of 220 packs per minute​ — striking the perfect balance between blistering speed and uncompromising precision.

The modular design enables rapid mold changes in just 8 minutes, making it ideal for modern flexible manufacturing that demands small batches and diverse product variations. The machine seamlessly handles mixed packaging of screws, nuts, washers, springs, and other hardware components within a single production run.

Tianxuan’s Intelligent Formula Management System​ stores 10–20 distinct packaging recipes, allowing operators to switch instantly between different hex screw and lag bolt combinations with a single touch. Simply set the exact quantity of each fastener type on the intuitive HMI touchscreen, and the intelligent PLC control system orchestrates the entire workflow — from multi-channel feeding and precision counting to mixed bagging and sealing — fully automated and error-free.

Real-world performance data speaks volumes. When Hisense Air Conditioning deployed Tianxuan’s inline accessory packaging machines, daily processing volume exceeded 100,000 units with zero downtime. An automotive parts manufacturer saw production capacity jump from 200 packs/hour to 800 packs/hour while slashing labor costs by 60%. An electronic component manufacturer leveraging the AI vision counting system achieved 80 combo sets per minute with near-zero error rates, cutting customer complaints by 90%.

The global screw packing machine market reached approximately RMB 5.215 billion in 2025​ and is projected to grow steadily to RMB 6.613 billion by 2032, representing a CAGR of 3.5%. China stands as the world’s largest consumer market for these machines, with growth rates exceeding the global average. Within China’s domestic hardware packaging sector, Tianxuan commands a market share exceeding 25%​ — a testament to its technological leadership and trusted reputation among industry players.

Mixing hex head screws and lag bolts in a single package may appear straightforward, but it rigorously tests a machine’s ability to adapt to varying material geometries, maintain pinpoint counting accuracy, and intelligently manage complex production rhythms. With 29 core patents, over 6,000 enterprise partners, and products shipped to more than 80 countries, Guangdong Tianxuan Packaging Machinery delivers a truly “zero-error, high-efficiency, cost-effective”​ mixed packing solution that defines the gold standard of Chinese intelligent manufacturing.
