Prefabricated Housing Component Mold Processing

Prefabricated housing component mold processing covers multiple aspects including mold types and functions, design and manufacturing, materials, usage and maintenance, as well as related enterprises and technologies.

Mold Types and Functions

• Prefabricated Component Molds: Primarily made of steel molds, they employ wet demolding technology. The use of wing-shaped torsion springs for positioning, oil lubrication in sliding grooves to enhance mobility efficiency, modular chamfering forming tooling to reduce modification costs, and new positioning systems such as magnetic box-fixed side molds to improve precision. These molds are used for producing six types of standard components, including composite floor slabs and balcony slabs, with high reusability for large base molds.
• Cement House Molds: Evolved from traditional large steel building formwork, these molds are used for factory-prefabricated integral concrete houses. Core components include mold liners, exterior wall molds, bases, and slide rails, with a self-weight exceeding 20 tons. They form casting cavities through opening and closing, combined with steam curing processes to accelerate concrete hardening. After four generations of technological upgrades, these molds can be reused for approximately 5 - 8 years, adapting to the production needs of housing factories of different scales.

Mold Design and Manufacturing

• Design: New approaches such as modular design, combined molds, and optimized structures are adopted. Nantong Oulida Construction Technology Co., Ltd. can undertake mold design, with experienced technical personnel.
• Manufacturing: The manufacturing of prefabricated component molds requires adherence to stiffness calculation specifications, with support structures selected from section steel or steel plates. Cement house molds are made of Q345B high-strength steel, equipped with high-precision processing equipment. They undergo structural scheme论证 (demonstration), mechanical analysis, and fatigue strength testing to consider component strength and service life.

Mold Materials

The composite application of fiberglass and aluminum alloy is explored, reducing weight compared to traditional steel molds while maintaining the same stiffness. Cement house molds are made of Q345B high-strength steel.

Mold Usage and Maintenance

• Usage: During operation, cement house molds form cavities to accommodate steel reinforcement cages and concrete. After concrete pouring, thermal insulation covers are used to enclose the molds and the concrete inside, with steam introduced for concrete curing. Some opening molds are assembled in a scattered form and secured with strong magnets.
• Maintenance: Finished prefabricated component molds should be coated with engine oil for rust prevention during storage. Structural inspections are required when the number of turnovers is high. Cement house molds can be reused more than 300 times, with a lifespan of approximately 5 - 8 years.
