Linfen Prefabricated Housing Component Molds

Linfen prefabricated housing component molds, primarily consisting of cement housing molds, are key equipment for shaping concrete prefabricated products, featuring technological upgrades, diverse structures, and superior performance.

I. Mold Types and Technological Development
Cement housing molds have evolved from traditional large steel building formwork, undergoing four generations of technological upgrades:

• First-generation molds: Simple structure, straightforward process, and low procurement cost. However, the walls are wider at the top and narrower at the bottom, with a 3-centimeter difference in wall thickness on a single side, limiting precision.
• Second-generation molds: Achieve vertical wall forming. Through a unique mechanical structure, the inner mold is contracted and demolded by external operations, ensuring consistent wall thickness from top to bottom and resolving wall inclination issues.
• Third-generation molds: Support multi-size adjustments. The mold width and length can be adjusted in multiple gears, allowing one mold to meet various size requirements and significantly enhancing flexibility.
• Fourth-generation molds: Adopt a fully automatic hydraulic system, integrating electric vibration functions to achieve hydraulic demolding, mold closing, reinforcement locking, and full automation of the entire process, ensuring safety and efficiency without manual intervention.

II. Core Components and Working Principle
The mold consists of an inner liner, 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 cavity through mold opening and closing to accommodate steel reinforcement cages and concrete. After pouring, the mold is sealed with an insulating cover, and steam is introduced for concrete curing, accelerating strength growth and shortening demolding time.

III. Product Specifications and Performance Advantages

• Materials and Lifespan: Made of Q345B high-strength steel, the molds can be reused over 300 times with a lifespan of approximately 5-8 years. The mold precision reaches ±1mm, equipped with a 20,000-watt laser cutting machine and high-precision processing equipment to ensure accurate dimensions.
• Environmental Protection and Economy: The molds have a high reuse rate, reducing waste of disposable materials like wood. Factory production reduces on-site wet work, saving construction costs and shortening the project cycle.
• Technological Patents: Some molds apply new patent technologies (e.g., CN 222003872 U), improving mold closing and demolding precision and further ensuring pouring quality.

IV. Comparison of Features Among Different Mold Types

• First-generation molds: Simple and reliable structure but limited precision, suitable for scenarios with low requirements for wall verticality.
• Second-generation molds: Vertical walls and convenient demolding, suitable for standardized production needs.
• Third-generation molds: Adjustable size and high flexibility, meeting diverse engineering requirements.
• Fourth-generation molds: Fully automatic operation, safe and efficient, representing the highest level of current technology.
