Jiangsu Prefabricated Wall Panel Molds for Houses
The following is an overview of prefabricated wall panel molds for houses in Jiangsu:
Mold Composition and Manufacturing Principles
Prefabricated courtyard wall molds are specialized tools used to pre-form concrete walls before wall construction. They consist of panels, support frames, connectors, and demolding devices. The panels are typically made of steel plates, and their surface flatness directly affects the final quality of the concrete wall surface, requiring high-precision machining. The support frames are mostly welded from profiled steel to ensure the mold maintains structural stability during concrete pouring and curing, preventing deformation. The connectors enable tight assembly and quick disassembly of mold parts through standardized design, improving construction efficiency. The demolding devices assist in separating the finished wall from the mold using mechanical or hydraulic systems, reducing manual intervention.
Manufacturing Process and Quality Control
The mold manufacturing process covers material selection, blanking, forming, welding, and surface treatment. In material selection, the panel steel must have sufficient hardness and corrosion resistance, while the support frame should preferably use high-strength profiled steel. During the blanking stage, CNC cutting technology ensures component dimensional accuracy, with errors controlled within ±0.5mm. The forming process uses plate bending machines or presses to bend steel plates into the required curved surfaces or angles to meet complex wall design requirements. The welding process employs carbon dioxide gas shielded welding to minimize deformation, and welds must undergo non-destructive testing (such as ultrasonic testing) to ensure structural strength. Surface treatment includes shot blasting for rust removal and spraying anti-rust paint to extend the mold's service life. Quality inspection focuses on dimensional tolerances, flatness, and assembly accuracy, using three-dimensional coordinate measuring instruments to verify key dimensions, flat plates and feeler gauges to inspect panel flatness, trial assembly to verify component compatibility, and simulated pouring tests before shipment.
Enterprise and Patent Layout in Jiangsu
Jiangsu Xinyu Residential Industry Technology Co., Ltd. is a representative enterprise in this field, specializing in the research and development, production, and installation of concrete prefabricated components, including wall panels, and also involved in mold manufacturing. As of 2025, the company holds 32 patent records, with an invention patent titled "A Production Mold for Prefabricated Insulated Sandwich Wall Panels" authorized in 2025, reflecting its technological innovation capabilities in mold design. Additionally, Jiangsu GeGou Prefabricated Housing Component Co., Ltd. is engaged in the production of PC components, including prefabricated shear wall panels. Although mold manufacturing is not explicitly mentioned, the production of PC components inevitably involves the design and application of related molds, indirectly reflecting the industrial agglomeration effect in the field of prefabricated wall panel molds in Jiangsu.
