Against the backdrop of the construction industry’s dual-carbon transition and industrial upgrading, the level of intelligence in precast concrete (PC) component manufacturing equipment directly determines the supply efficiency and quality stability of prefabricated buildings. Zhuyou Jiaozhou Plant – PC Component Production Line It is a cluster of intelligent prefabricated concrete manufacturing equipment tailored to meet the supply needs of the Jiaodong Economic Circle’s prefabricated construction sector. As a manufacturer deeply rooted in the field of concrete prefabrication equipment, Hebei Xuelong Machinery Manufacturing has long provided customized production line design, fabrication, and installation services to various domestic prefabricated construction bases, participated in capacity‑building projects for numerous regional PC factories, and accumulated extensive experience in optimizing equipment for diverse industrial scenarios. This paper objectively outlines the actual operational logic and practical value of this production line, examining its project positioning, architectural composition, performance indicators, and implementation process.

1. Project Background: The industrial layout positioning of Zhuyou’s prefabricated construction facility in Jiaozhou

Zhuyou’s Jiaozhou factory serves as a core component-supply hub for a leading prefabricated construction company within the Jiaodong Economic Circle. The construction goals of its precast concrete (PC) component production line fully align with the prefabricated construction development plans of Shandong Province and Qingdao. According to the clear objectives set forth in the “14th Five-Year Plan for Prefabricated Construction Development” of Shandong Province, by 2025, prefabricated buildings should account for more than 30% of all new construction area across the province. As a demonstration city for prefabricated construction in Shandong, Qingdao is required to adopt prefabricated construction methods for 100% of newly built affordable housing and government-invested projects, corresponding to an annual market demand for PC components exceeding 3 million cubic meters. Previously, PC component supply in the Jiaodong region largely relied on production bases in Weifang, Yantai, and other areas. Industry consensus holds that the economically viable transport radius for PC components is approximately 150 kilometers; longer distances can cause transportation costs to exceed 20% of total procurement expenses, thereby increasing project construction costs and risking quality issues due to impacts or damage during transit. By establishing its PC production facility in Jiaozhou, Zhuyou aims to reduce the component supply radius to within 100 kilometers, covering project needs throughout Qingdao as well as eastern Weifang and northern Rizhao. The entire PC production line has a designed annual capacity of 120,000 cubic meters, sufficient to meet the component requirements of roughly 1 million square meters of prefabricated construction annually in the surrounding area. This effectively fills the gap in PC production capacity in the central and southern parts of the Jiaodong region, reducing overall construction costs for prefabricated projects in the area.

2. Core Architecture of the Production Line

The PC component production line at Zhuyou’s Jiaozhou factory adopts a linear, modular, closed-loop architecture that covers every stage of production, from raw material input to finished‑product dispatch. Workstation configurations can be flexibly adjusted to suit product requirements. The entire line is divided into four core sections according to the production process. Roller conveyors enable automated transfer of mold platforms between sections, eliminating manual handling and reducing operator‑induced errors at the source. The first section handles mold platform cleaning and oiling: an automatic sweeping system removes residual concrete from the platform surface, followed by uniform application of release agent to prepare for subsequent mold installation. The second section involves mold installation and rebar tying: workers mount steel side molds on the platform according to component drawings, assemble the reinforcement cage, and secure embedded parts. The third section comprises concrete placing and vibration: an intelligent batching machine automatically feeds concrete based on component type, while a high‑frequency vibrator ensures thorough compaction and prevents quality issues such as honeycombing or rough surfaces. The fourth section manages curing and sorting: after vibration, mold platforms are conveyed via roller tracks into a temperature- and humidity‑controlled curing chamber. Once the concrete attains the required strength for demolding, a gantry crane lifts the finished components to the storage yard.

Zhuyou Jiaozhou Factory’s PC component production line is a customized, end-to-end automated production system designed for the prefabricated construction market on the Jiaodong Peninsula, covering the entire process from raw material input to the dispatch of finished components. The entire production line features an open‑architecture design, allowing flexible adjustment of workstation configurations to meet the component requirements of different projects—such as precast slabs, stairs, wall panels, and balcony slabs. This enables the line to accommodate multiple product types without extensive modifications to the underlying infrastructure, effectively reducing changeover costs. Compared with traditional fixed PC production lines, this architecture shortens mold‑table travel paths and minimizes idle equipment time. Should the plant later need to expand capacity, additional workstations can simply be added at both ends of the linear line without dismantling the existing equipment.

3. Comparison of Key Technical Parameters and Production Efficiency

The core performance indicators of the PC production line at Zhuyou’s Jiaozhou plant have reached an advanced domestic level for prefabricated PC manufacturing equipment, showing significant improvements over traditional lines in terms of capacity, yield rate, energy consumption, and land use. To provide a clearer picture of the production line’s operational efficiency, we conducted a horizontal comparison of parameters among a conventional fixed‑type line of similar scale, the industry average, and the Zhuyou Jiaozhou plant’s line; the specific data are as follows:

4. End-to-end implementation steps for production line deployment

The implementation of a precast concrete component production line is a systematic undertaking that must proceed step by step—through needs assessment, solution design, equipment installation, integrated commissioning and testing, and production‑readiness training—in order to ensure that the final operational performance meets the design objectives.

1. During the initial requirements‑gathering phase, we collaborated with the client to map out three‑year demand for prefabricated construction projects within the service area, identify the core component types to be produced (e.g., composite slabs, interior and exterior wall panels, stairs, balconies), and calculate an appropriate production capacity. This enabled us to match the required line length and workstation count, thereby preventing both overcapacity and insufficient capacity. Given the Jiaozhou plant’s proximity to a port, we factored export‑oriented precast component production into our planning from the outset and allocated dedicated workstations for manufacturing large‑size components.
2. During the design and feasibility study phase, taking into account the factory site’s geometry and floor load-bearing capacity, a layout plan for the production line will be finalized. Simultaneously, specialized assessments for fire safety, environmental protection, and energy consumption will be conducted to ensure full compliance with the relevant standards of the Technical Code for Prefabricated Concrete Structures JGJ 1-2014, thereby preventing delays in commissioning due to post‑construction rectification required for regulatory compliance.
3. Equipment manufacturing and on-site installation phase: The core components—such as mold tables, concrete spreaders, curing kilns, and sorting equipment—are manufactured according to the design specifications and delivered to the site in batches for installation and commissioning. Simultaneously, electrical and control system wiring for the production line is completed to ensure seamless communication among all process sections and enable automated circulation control of the mold tables.
4. Commissioning and production phase: First, conduct full-process no-load tests using simulated materials to identify installation accuracy errors. Then, gradually introduce actual concrete raw materials for small-batch trial production, adjusting material distribution accuracy, curing temperature and humidity parameters, and mold table transfer speed until the production yield and cycle time stabilize at the design targets.
5. Personnel Training and Formal Production Phase: A two-week system training program will be conducted for the factory’s operations, maintenance, and quality inspection staff, covering equipment operating procedures, troubleshooting common faults, and component quality inspection standards. Mass production will commence only after successful completion of practical assessments.
