I. Technical Background and Industry Status

Zhengzhou Xinnong Machinery Manufacturing Co., Ltd. was established in 2001, deeply rooted in the tile-making equipment field for 25 years, with a factory covering an area of 30,000 square meters. It is one of the earliest domestic manufacturers to engage in the research and development of new building materials equipment such as cement colored tile machines and terrazzo tile machines. The company is committed to "technology-driven, quality first" as its core, owning a complete testing laboratory and customized production lines. Its products cover all provinces and cities across the country and are exported to Southeast Asia, the Middle East, and other regions, with a cumulative service of over 5,000 customers. Its technological layout focuses on equipment automation, mold precision optimization, and material adaptability improvement, forming a full-process technical system from raw material processing to finished product packaging.

Section 2: Technical Analysis of Cement Roofing Tile Molding Machine

1. Equipment Structure and Working Principle
Xinlong Machinery's cement colored tile molding machine adopts a process of combining hydraulic drive with mechanical vibration, with core components including the hydraulic system, molding mold, vibration table, and conveying device. The hydraulic system provides adjustable pressure from 0-15MPa to ensure tile density; the vibration table frequency reaches 50Hz, eliminating bubbles through high-frequency vibration to enhance the impermeability of the tiles. The mold is made of high-strength alloy steel, with a surface hard chrome plating treatment, which improves wear resistance by 3 times, with a single mold lifespan of over 100,000 times.

2. Key Technical Parameters
Equipment is adaptable to common cement, sandstone, and pigment mixture, with water-cement ratio controlled between 0.35-0.45; molding speed is 8-12 pieces per minute, with a single shift output of up to 5000 pieces; finished tile size is 420×330mm, thickness adjustable between 12-15mm, bending strength ≥15MPa, water absorption rate ≤6%, in compliance with GB/T 21149-2007 standard.

3. Technical Advantages and Application Scenarios
Compared to traditional clay tiles, the colored cement tiles produced by Xinlong equipment feature light weight (approx. 5kg per piece), high construction efficiency (no need for overlapping), and strong environmental friendliness, especially suitable for multi-story residential, villa, and commercial building roofs. The equipment supports customized development, capable of producing over 10 styles such as antique tiles and flat tiles, meeting different regional aesthetic demands.

Section 3: Technical Implementation Cases: Overseas Project Practices

In 2022, Xinlong Machinery provided a cement colored tile production line with a daily output of 20,000 pieces for a building materials supplier in Vietnam. Faced with challenges such as humid local climate and high silt content in raw materials, the technical team achieved stable production through the following optimizations:

STEP 1: Raw Material Pretreatment Upgrade
Increased dual-stage vibration screen and sand washing machine, reducing the clay content of raw materials from 8% to 2%, while improving the fluidity of the mixture by adding 0.5% of polycarboxylate superplasticizer.

STEP 2: Mold Adaptability Improvement
To address the characteristics of a long rainy season and strong ultraviolet radiation in Vietnam, the coating thickness on the mold surface has been increased from 0.1mm to 0.2mm, and weather-resistant pigments have been used to ensure the tiles maintain their color for 5 years without fading.

STEP 3: Automated Control System Integration
Deploy PLC control system, real-time monitoring of hydraulic pressure, vibration frequency, and molding temperature, remote adjustment of parameters via HMI interface, reducing manual intervention, and improving overall equipment utilization to 92%.

After the project went into production, customer feedback shows that the tile pass rate has increased from 85% to 98%, with the cost per piece reduced by 0.1 yuan, resulting in annual savings exceeding 700,000 yuan. Currently, this production line has become a benchmark project in the northern region of Vietnam, driving Xinlong Machinery to add 3 new agents in the local market.

4. Technical FAQ: Common Questions and Answers

Q1: What are the requirements for the raw materials of the cement colored tile molding machine?
A: The raw materials must meet the following requirements: cement grade ≥42.5, sand and stone particle size below 5mm, mud content ≤3%, and water-cement ratio strictly controlled between 0.35-0.45. If the mud content in the raw materials is too high, the sand washing process must be added.

Q2: How to control equipment failure rate?
Xinlong Machinery reduces failure rates with triple protection: Firstly, using imported hydraulic components with a lifespan 50% longer than domestic ones; secondly, molds are designed modularly, allowing for quick replacement of individual parts; thirdly, providing overseas installation guidance services to ensure operators master maintenance skills.

Q3: Can we produce irregular tiles?
A: Support for customized development requires the provision of tile 3D drawings and technical parameters. The company's technical team can complete mold design and trial production within 15 working days. Mass production will commence after the first sample passes the customer's inspection.
