Prefabricated Housing Component Molds

Prefabricated housing component molds are key tools for manufacturing cement houses or building components, primarily divided into three categories: prefabricated component molds, cement house molds, and prefabricated cement house molds. Their characteristics and applications are as follows:

1. Prefabricated Component Molds These molds, primarily constructed from steel, are mainly used for producing six types of standard components, such as composite floor slabs and balcony slabs. Their core functions include:

• Wet Demolding Technology: Reduces component damage and improves surface quality by optimizing the demolding process.
• Modular Design: Lowers mold modification costs and adapts to different component size requirements.
• Magnetic Box Fixed Side Molds: Adopts a new positioning system to enhance mold assembly accuracy and stability. The mold structure consists of standardized components, including a base mold, side molds, and end molds. During manufacturing, stiffness calculation specifications must be followed to ensure load-bearing capacity. When stored, they should be coated with machine oil to prevent rust and extend service life. Current technological advancements focus on the composite application of automated demolding devices and lightweight materials (such as fiberglass and aluminum alloy) to reduce mold weight and improve demolding efficiency.

2. Cement House Molds Evolved from traditional large steel building formwork, these molds are used for factory-prefabricated integral concrete houses. Their core components include mold liners, exterior wall molds, bases, and slides, with a self-weight exceeding 20 tons. Technical characteristics include:

• Opening and Closing Mold Process: Forms a casting cavity through mold opening and closing, combined with steam curing to accelerate concrete hardening and shorten the production cycle.
• Fourth-Generation Technological Upgrades: Adopts a fully automatic hydraulic system and electric vibration function, achieving mold precision of ±1mm, with over 300 reuse cycles and a service life of approximately 5-8 years.
• Hydraulic Drive and Electrical Control: Enables precise mold movements and automated production. Some opening molds are assembled in a scattered form, supplemented by strong magnets for fixation, enhancing assembly flexibility. Third-generation molds support multi-size adjustments, while fourth-generation molds achieve fully automated operation without manual intervention, significantly improving production efficiency.

3. Prefabricated Cement House Molds Typically made from wear-resistant steel or aluminum alloy, these molds can be customized in shape and size according to needs. Their characteristics include:

• Manufacturing Process: Covers design, processing, production, and surface treatment to ensure mold precision and durability.
• Application Areas: Widely used in residential, commercial, and industrial buildings, improving construction efficiency and ensuring quality.
• Advantages and Disadvantages: Advantages include cost reduction and shortened construction periods; disadvantages include the need for strict storage and maintenance (such as moisture and rust prevention), control of construction parameters (such as concrete pouring speed), and enhanced personnel training to avoid operational errors leading to mold damage or component defects.

All three types of molds promote the development of building industrialization through standardized design and technological upgrades, but the type must be selected according to specific needs, and usage procedures must be standardized.
