Prefabricated Housing Molds

Prefabricated housing molds are equipment used in factories for forming concrete prefabricated components for integral concrete houses. They have evolved from traditional large steel building formwork and are characterized by high efficiency and reusability.

Core Structure and Function

The core components of prefabricated housing molds include the mold liner, exterior wall mold, base, and slide rails. They typically weigh over 20 tons and require strict adherence to safety operation protocols. Their working principle involves forming a casting cavity through mold opening and closing. After concrete is poured, steam curing processes are used to accelerate hardening, shortening the production cycle. The closing and opening of the molds rely on hydraulic or mechanical systems to ensure the precision of component forming.

Technological Iteration and Performance Enhancement

Prefabricated housing molds have undergone four generations of technological upgrades:

1. First Generation: Simple structure with single functionality, suitable for basic component production.
2. Second Generation: Enabled vertical wall forming, enhancing the three-dimensional production capacity of components.
3. Third Generation: Supported multi-size adjustments to accommodate different housing specifications, increasing flexibility.
4. Fourth Generation: Adopted fully automatic hydraulic systems and integrated electric vibration functions, significantly improving production efficiency and concrete compactness.

Service Life and Specification Parameters

The reusable cycle of molds is approximately 5-8 years, with the specific lifespan influenced by material quality, maintenance frequency, and usage intensity. The specifications of the components they produce are as follows:

• Wall Thickness: 14-17 cm, meeting structural strength and insulation requirements;
• Slab Thickness: 10-13 cm, suitable for different scenarios such as floor slabs and roof panels. By prefabricating components in a centralized manner, molds can significantly shorten on-site construction periods, making them particularly suitable for large-scale housing factory production.

Market Brands and Price Differences

Mainstream brands in the market include Zheng'en Molds, Haitian Electromechanical, Shengrui, Chengsen, Bairui, Tengshi, and Huiwei Molds, among others. Prices vary significantly depending on the brand, model, and configuration:

• The price of prefabricated cement house molds from Hebei Zheng'en Construction Engineering Co., Ltd. is 198,000 yuan per ton or 198,000 yuan per unit;
• The price of integrated housing molds from Shandong Dezhou Haitian Electromechanical Technology Co., Ltd. is 20,000 yuan per set. Price fluctuations are mainly influenced by mold materials (such as high-strength steel), automation levels, and additional functions (such as vibration systems). When purchasing, it is necessary to comprehensively evaluate production scale and budget.

Application Value and Industry Trends

Prefabricated housing molds enhance component quality through standardized production and reduce on-site wet operations, aligning with the trend of building industrialization. With technological upgrades, molds are evolving towards intelligence and modularity, such as integrating sensors to monitor curing temperatures or using 3D printing technology to customize irregular components, further expanding their application scenarios.
