In modern tunnel construction projects, the processing efficiency and precision of small duct components directly impact overall project quality and progress. As a professional manufacturer of tunnel construction equipment, Xuhui (Shandong) Smart Equipment Co., Ltd. has developed an advanced small duct punching and shrinking integrated production line that integrates multiple processing functions into one system, providing efficient and precise solutions for global tunnel projects.
Technical Advantages of Integrated Production Line
The small duct punching and shrinking integrated production line developed by Xuhui (Shandong) represents a significant technological breakthrough in tunnel equipment manufacturing. This system combines three core processing functions – automatic feeding, precise punching, and controlled shrinking – into one continuous production line, eliminating the need for multiple equipment transfers and manual operations between processes.
The production line features a high-precision servo feeding system capable of maintaining ±0.1mm positioning accuracy throughout continuous operation. The punching unit adopts a multi-station rotary die design that can complete complex hole patterns in a single operation, with punching force adjustable from 5 to 30 tons to accommodate different material specifications. The shrinking section utilizes an induction heating system with temperature control accuracy of ±5°C, ensuring consistent shrinking quality across all components.
Compared with traditional processing methods, our integrated production line demonstrates the following technical advantages:
- Processing efficiency increased by 300%
- Labor cost reduced by 70%
- Product consistency improved to 99.5%
- Energy consumption decreased by 40%

FAQ
What certifications do your tunnel equipment have for international projects?
All our tunnel equipment, including the small duct punching and shrinking production line, have obtained CE certification from TÜV Rheinland, meeting EU safety, health, and environmental requirements. We can also provide custom certification services according to specific country requirements such as GOST-R for Russia or EAC for Eurasian Economic Union countries.
How does your production line ensure processing consistency?
The consistency is guaranteed through multiple quality control measures: 1) High-precision servo feeding system with closed-loop control; 2) CNC punching unit with automatic die compensation; 3) Induction heating system with precise temperature control; 4) In-process quality inspection stations; 5) Data traceability system for every component processed.
What is the maximum processing capacity of your production line?
The standard configuration can process 1,200-1,500 meters of small duct per 8-hour shift, depending on the component complexity. For projects requiring higher capacity, we offer customized solutions with dual-line parallel processing or automated material handling systems that can increase daily output to over 3,000 meters.
How do you handle equipment maintenance for international projects?
We provide a comprehensive maintenance solution including: 1) Preventive maintenance schedule based on actual operating hours; 2) On-site maintenance by certified technicians; 3) Remote diagnosis and troubleshooting; 4) Regular software updates; 5) Spare parts supply with 3-year warranty. For critical projects, we can arrange long-term on-site service contracts.
