Chongqing Prefabricated Building Component Molds

The following is an overview of prefabricated building component molds in Chongqing:

Mold Materials and Types

In the manufacturing of prefabricated component molds in Chongqing, material selection is based on the requirements of the components. Steel plates are the mainstream material for manufacturing large prefabricated wall panel molds due to their high strength, good wear resistance, and high reusability, making them suitable for scenarios with high structural strength and durability requirements. Engineering plastics or fiberglass-reinforced plastics are used for component molds with complex shapes or special requirements for surface finish, such as decorative fence panels. Their advantage lies in their ease of processing into complex shapes and high surface quality.

Mold Production Process

Mold manufacturing involves multiple precision processes:

1. Reverse Design: Based on the digital model of architectural design, determine the parting surface, pouring port, vent hole, and reinforcement positions to ensure smooth concrete flow and stable component structure.
2. Steel Processing: Use laser cutting, bending, and other processes to process the plates into preset shapes. Key modules require high-precision assembly and welding to form a closed cavity to prevent concrete leakage.
3. Surface Treatment: After overall mold calibration, perform polishing or spraying to achieve the required flatness and finish, reducing the risk of concrete adhesion.

Quality Control Points

Mold quality is ensured through multiple validations:

• Mold Testing: Before delivery, use the same concrete mix ratio as in production to make sample walls to verify smooth demolding, component dimensional tolerances, and surface defects (such as air holes and cracks).
• Precision Monitoring: Regularly inspect key positioning dimensions. Components with wear beyond the allowable range need to be repaired or replaced to ensure dimensional stability during repeated use.
• Sealability Testing: Check for concrete leakage in the mold by simulating the pouring process to avoid affecting the surface finish of the components.

Mold Functional Characteristics

During the concrete production stage, steel molds serve as forming containers. Their structural rigidity ensures component dimensional stability, sealability prevents cement paste leakage, and high thermal conductivity accelerates the dissipation of hydration heat to reduce the risk of cracking. During the curing stage, the mold acts as a temporary protective shell, providing a stable microenvironment and reducing water evaporation. The design rationality directly affects the uniformity of curing. During demolding, detachability, demolding slope, and rounded corner treatment ensure the complete removal of the component. After cleaning, the mold can be reused.
