Cement Mold Prefabricated Housing

Cement mold prefabricated housing is a construction method that utilizes cement house molds to prefabricate entire concrete houses in factories, characterized by high efficiency, durability, and flexibility, albeit with relatively high mold costs.

I. Core Equipment and Process
The cement house mold is a key piece of equipment for shaping concrete prefabricated products. It consists of core components such as the mold inner liner, exterior wall mold, base, and slide rails, with a self-weight exceeding 20 tons. Its working principle involves forming a casting cavity through mold opening and closing, pouring cement or concrete inside, and then accelerating hardening through steam curing to ultimately form an integrated house structure. The mold exhibits remarkable durability, capable of being reused for approximately 5-8 years, with some molds even completing hundreds of cycles, significantly reducing long-term costs.

II. Technological Iteration and Functional Upgrades
Cement house molds have undergone four generations of technological innovation:

1. First Generation: Simple structure with basic functions, suitable for early small-scale production.
2. Second Generation: Achieved vertical wall forming, enhancing the structural stability of houses.
3. Third Generation: Supports multi-size adjustments to meet diverse architectural needs, increasing flexibility.
4. Fourth Generation: Adopts a fully automatic hydraulic system and integrates electric vibration functions to improve concrete compactness and production efficiency.

III. Housing Characteristics and Application Scenarios
Prefabricated houses have wall thicknesses ranging from 14-17 cm and panel thicknesses from 10-13 cm, providing a sturdy structure and good thermal insulation. The finished products can be directly hoisted and assembled, suitable for various scenarios such as residential houses, construction site dormitories, warehouses, and guardhouses. Their modular design supports centralized prefabrication of components, significantly shortening construction periods, and is particularly well-suited for the production needs of housing factories of different scales, from single houses to large-scale community construction, all of which can be completed efficiently.

IV. Economic Efficiency and Limitations
Despite the outstanding durability of molds and the construction efficiency advantages of prefabricated houses, the initial mold costs are relatively high, potentially increasing project upfront investments. Additionally, customized mold requirements (such as special sizes or functions) may further drive up costs. Therefore, this technology is more suitable for long-term, large-scale construction projects to maximize economic benefits by amortizing mold costs.
