The clink of precision tools and hum of calibration systems fill the workshop as Nanjing Litai’s engineering team completes the final commissioning of a custom bolt forging production line. This seamless on-site execution—spanning design, installation, debugging，and training—epitomizes the company’s turnkey service commitment and relentless pursuit of manufacturing perfection.
Turnkey Execution: From Blueprint to Workshop Integration
Long before the first component arrived, Litai’s engineers had laid the groundwork for precision. Leveraging digital simulation tools (consistent with the brand’s focus on forging innovation), the team optimized the line layout to minimize material transfer time while ensuring compliance with the client’s workshop space constraints. “We modeled every conveyor angle and robot reach in advance,” explains Wang , Litai’s on-site project manager. “This digital preparation cut on-site installation time by 18% compared to standard projects.”
The delivery phase showcased Litai’s end-to-end coordination. A 66-ton main press—similar in scale to high-performance forging equipment—was handing with millimetric accuracy using specialized rigging, while auxiliary systems (induction heating furnaces, lubrication workstations, and descaling machines) arrived pre-tested to reduce on-site troubleshooting. “Our one-stop service means clients never coordinate multiple vendors,” adds Wang. “We handle everything from foundation bolts to control system integration.”
Precision in Action: Calibration That Defines Quality
Installation rigor mirrored the precision of the bolts the line would produce. When aligning the induction heating furnace—critical for consistent bolt grain structure—technicians used laser measurement tools to achieve a positional tolerance of ±0.5mm, ensuring uniform heating up to 1100°C for carbon steel billets. This attention to detail echoes the standards that kept Dongfeng forge’s “national treasure line” operational for 47 years without major overhauls.
The closed-die forging station demanded even stricter calibration. Litai’s team adjusted the press’s PLC-integrated control system to maintain 5000kN of force with 0.1% variance, directly addressing the client’s requirement for Class 8 precision bolts. “Every parameter tweak ties back to real-world performance,” notes senior technician Cao, pointing to a digital readout tracking die alignment. “We test 20 sample bolts per calibration cycle until each meets ISO 898-1 standards.”
Commissioning: Perfecting Every Production Beat
The line’s first test run revealed Litai’s dedication to operational excellence. As robotic arms transferred billets from heating to forging stations, engineers monitored cycle times, fine-tuning conveyor speeds to achieve a steady 8-second beat —matching the efficiency of advanced automated lines while maintaining precision. When initial tests showed a 0.3mm deviation in bolt head dimensions, the team recalibrated the trimming unit within two hours, avoiding costly delays.
Sustainability and reliability were woven into every step. The descaling machine was calibrated to capture 95% of oxide scale for recycling (consistent with Litai’s green forging focus), while the lubrication system’s glycerin-based delivery (a proven upgrade from traditional thin oil solutions) was adjusted to extend die life by 20%. “Our clients don’t just get equipment—they get a line built for long-term performance,” Wang emphasizes.
Beyond Installation: Empowering Client Teams
The final phase of Litai’s turnkey service ensured the client’s team was fully equipped to maximize the line’s potential. A two-day training program covered everything from PLC system troubleshooting to predictive maintenance using the line’s cloud-based monitoring tools—features designed to reduce unplanned downtime by 30%. “We stayed an extra day to run through emergency protocols,” says Cao. “Excellence means leaving no questions unanswered.”
As the line begins full production, producing 50,000 high-precision bolts daily for automotive and construction clients, the workshop floor tells the story of Litai’s service philosophy. “From the first design consultation to the final test bolt, this project embodies our promise—one team, one solution, zero compromises,” concludes Wang.
