Chongqing Prefabricated Wall Panel Mold for Houses
In Chongqing, steel molds are the mainstream for prefabricated wall panel molds for houses, characterized by high precision, long service life, and adaptability to complex climates. Their production involves precise design, strict quality inspection, and collaboration among specialized enterprises.
Mold Material and Performance Advantages
In Chongqing, steel molds are the core of prefabricated wall panel molds, with physical properties significantly superior to traditional materials. The elastic modulus of steel molds reaches 200 gigapascals, more than 20 times that of wood, resulting in minimal deformation during concrete pouring and ensuring millimeter-level dimensional accuracy of components. In contrast, wooden formwork tends to warp after absorbing water, leading to flatness deviations of 5 to 10 millimeters in components. Plastic formwork has a thermal expansion coefficient approximately 2 to 3 times that of steel at high temperatures (such as the 70°C surface temperature in Chongqing summers), resulting in prominent deformation issues. Through precision machining, steel molds can control the draft angle between 0.5 and 1.5 degrees, far lower than the uneven draft angles caused by sawing errors in handmade wooden molds, reducing actual demolding damage rates by about three times. Additionally, when using carbon dioxide gas shielded welding, steel molds can achieve a fatigue life of over 500 cycles, while ordinary manual arc-welded molds are prone to weld cracking after 200 cycles.
Molding Logic and Quality Control
Prefabricated wall components are produced in factories using standardized molds, with key processes including draft angle design and trial mold testing. When the draft angle is less than 1 degree, the adhesive force between the concrete and the mold can easily cause edge chipping of the component, a risk mitigated by the precision machining of steel molds. Before mold delivery, trial molding is required, using the same concrete mix as production to create sample walls and inspect demolding smoothness, dimensional tolerances, and surface defects. Reuse accuracy is monitored through regular inspection of key positioning dimensions, with worn-out components requiring timely repair or replacement.
Specialized Enterprise Collaboration Model
Prefabricated wall mold factories in Chongqing rely on digital models for reverse design, determining structures such as parting surfaces and pouring ports. They process steel through laser cutting, bending, and other processes, ultimately assembling and welding them into closed cavities, which are then subjected to overall calibration and surface treatment to meet flatness requirements. Chongqing Youte Mold Co., Ltd. provides one-stop services including mold steel supply, vacuum heat treatment, and surface strengthening, covering multiple fields such as new energy and automotive parts. Chongqing Huanan Prefabricated Components Co., Ltd., as a large prefabricated component manufacturer in southwest China, covers products such as prefabricated interior and exterior wall panels, forming an industrial chain collaboration with mold enterprises.
