Shanghai Prefabricated Floor Slab Molds for Buildings

The prefabricated floor slab molds for buildings in Shanghai are mainly PC composite slab molds, which adopt steel mold structures and possess characteristics such as standardization, high load-bearing capacity, and reusability. The technological development focuses on automation and lightweighting.

1. Mold Types and Customization Services

There are manufacturers in Shanghai specializing in the production of PC composite slab molds that offer customization services for prefabricated floor slab molds. These molds are primarily used for producing standard components such as composite floor slabs. They can be adjusted in size, shape, and structure according to project requirements to meet the personalized needs of different architectural designs. Customization services typically cover the entire process, including mold design, material selection, processing and manufacturing, as well as installation and commissioning, ensuring precise matching between the mold and production needs.

2. Mold Structure and Material Characteristics

Prefabricated component molds generally use steel molds as the main structure, composed of standardized components including bottom molds, side molds, and end molds.

• Core Functions: They employ wet demolding technology, using lubricants or demolding agents to achieve non-destructive separation of uncured concrete components, preventing damage to the surface quality of the components.
• Material Selection: The supporting structures are made of section steel or steel plates, which need to be verified for their load-bearing capacity through stiffness calculation standards to ensure that the molds do not deform or get damaged during repeated use.
• Load-Bearing Capacity Design: The design values of the mold's load-bearing capacity must meet industry standard requirements to withstand the lateral pressure and vibration loads during concrete pouring, ensuring production safety.

3. Manufacturing and Maintenance Standards

Mold manufacturing must strictly adhere to stiffness calculation standards to ensure structural stability.

• Rust Prevention Treatment: When storing finished products, they need to be coated with engine oil or special rust preventatives to prevent oxidation and corrosion on the surface of the steel molds, extending their service life.
• Reusability Inspection: When molds are reused many times, structural inspections must be carried out, focusing on checking the connection parts, supporting structures, and surface flatness, and promptly repairing worn or deformed components.
• Technological Upgrades: Current technological development focuses on the composite application of automated demolding devices and lightweight materials. For example, achieving rapid demolding through hydraulic systems or using lightweight materials such as aluminum alloys to reduce the self-weight of the molds and improve operational efficiency.

4. Application Scenarios and Advantages

Prefabricated floor slab molds are widely used in prefabricated building projects. Their standardized design can shorten the production cycle of components and improve construction efficiency. The high-precision characteristics of the steel mold structure ensure the consistency of component dimensions, reducing on-site installation errors. At the same time, they support large-scale industrial production, aligning with the development trends of green buildings and energy conservation and emission reduction.
