Prefabricated House Pouring Mold

The prefabricated house pouring mold is a concrete preforming device used in factories for the prefabrication of integral concrete houses, evolved from traditional large steel building formwork. The following provides an introduction from aspects such as structure, technological upgrades, service life, market brands, and usage processes:

Core Structure and Function
The mold consists of core components such as an inner mold, exterior wall mold, base, and slide rails, weighing over 20 tons and requiring strict adherence to safety operation protocols. Its working principle involves forming a casting cavity through mold opening and closing, combined with steam curing processes to accelerate concrete hardening, enabling rapid component forming.

Technological Iteration History
It has undergone four generations of technological upgrades:

• First Generation: Simple structure with basic functions, suitable for early small-scale production.
• Second Generation: Achieved vertical wall forming, enhancing component structural stability.
• Third Generation: Supports multi-size adjustments to meet the needs of different house specifications, such as the mold from Zhuoyi brand in Dongying, Shandong, which adopts an inner mold telescoping and outer mold track design.
• Fourth Generation: Utilizes a fully automatic hydraulic system, integrating electric vibration functions, exemplified by the mold from Haitian Electromechanical in Dezhou, Shandong, which allows sliding mold opening and significantly improves operational efficiency.

Service Life and Specification Parameters
The mold can be reused for approximately 5-8 years, with wall thicknesses ranging from 14-17 cm and panel thicknesses from 10-13 cm. It enables centralized prefabrication of components to shorten construction periods, catering to the production needs of factories of different scales.

Market Brands and Price Differences

• Fangda brand cement movable box mold from Baoding, Hebei: 4350.00 yuan per piece, focusing on simple structures.
• Bairui brand prefabricated cement house mold from Jingdezhen, Jiangxi: 9700.00 yuan per ton, priced by weight, suitable for large-scale purchases.
• Haitian Electromechanical mold from Dezhou, Shandong: 5500.00 yuan per unit, supporting size adjustments with outstanding cost-effectiveness.
• Zhuoyi brand mold from Dongying, Shandong: 6700.00 yuan per ton, adopting third-generation technology with more flexible functions.
  Additionally, new molds for modular concrete prefabricated houses can be easily assembled and disassembled, offering flexible customization, albeit at a higher mold cost.

Factory Prefabrication Process
Workers assemble metal steel plates into molds using bolt connectors, apply a release agent to the surface, place steel bars and tie them into a mesh framework, then fill with concrete and use vibrators to remove air bubbles. Finally, they cover with plastic sheds and install heating devices to promote cement hydration reactions.
