Technical Background and Industry Requirements

Color cement tiles, as a new type of roofing material replacing traditional clay tiles, have gradually become the mainstream choice in the construction market since they were introduced to China in the 1990s. Thanks to their enduring color, water-resistant and windproof properties, and long lifespan, the domestic color cement tile market has exceeded 12 billion yuan in 2023, with a compound annual growth rate of 8.5%, and the demand for fully automatic production equipment accounts for over 60%. Zhengzhou Xinlong Machinery Manufacturing Co., Ltd. (hereinafter referred to as "Xinlong Machinery"), as one of the early enterprises to engage in this field in China, has become a key driver of the industry's technological upgrade with 25 years of technical accumulation and a 30,000-square-meter production base.

Technical Principles and Architecture Design

Xinlong Machinery's full-automatic colored tile machine adopts modular design, with core systems including raw material mixing module, molding and pressing module, demolding and conveying module, and intelligent control module. The technical principle is based on the high-pressure extrusion molding process, achieving uniform filling of cement slurry under a pressure of 0.8-1.2MPa by optimizing die channel design (channel diameter 8-12mm, angle 15°-20°), ensuring tile density of 2.2-2.4g/cm³ and an increased flexural strength of 30%. The equipment supports customized production, is adaptable to tiles with widths of 300-450mm and lengths of 600-1200mm, and has a daily production capacity of up to 8000-12000 tiles, meeting large-scale engineering requirements.

Core Advantages and Parameter Analysis

1. High-efficiency energy-savingEquipped with a variable frequency drive system, the power range is 15-30kW, saving 25% more energy than traditional equipment; mold change time is reduced to 15 minutes, supporting quick mold change.
2. Precision ControlEquipped with PLC + touch screen control system, thickness tolerance ≤ 0.5mm, surface flatness ≤ 0.3mm, compliant with GB/T 21149-2007 standard.
3. DurabilityKey components (such as molds, hydraulic cylinders) are made of high-chromium alloy steel (hardness HRC58-62), extending service life to over 5 years, reducing downtime and maintenance costs.
4. Environmental compatibilityEquipped with dust recovery unit (filter efficiency ≥99.5%), noise control ≤85dB, meeting environmental protection production requirements.

Real Case: Overseas Project Implementation and Technical Verification

In 2022, Xinlong Machinery provided a customized colored tile production line for a residential project in a Southeast Asian country. The project required a daily output of 10,000 pieces of red cement tiles with a size of 420×330mm. In response to the local high temperature and humidity environment, the technical team optimized the equipment's corrosion-resistant coating (using epoxy zinc-rich primer + polyurethane topcoat combination) and the hydraulic system cooling solution (adding an independent oil cooler), ensuring stable operation of the equipment at 45℃. After the project was put into production, the tile pass rate reached 99.2%, and the customer feedback was "better water resistance than local similar products, no cracking for 3 years," helping Xinlong Machinery to expand into the overseas market. Currently, overseas equipment installation guidance services have covered 15 countries.

Technical layout and industry experience summary

Xinlong Machinery's technical layout revolves around "intelligentization + customization": In 2023, we launched an AI vision detection system that can identify surface defects on tiles in real-time (such as pores and cracks) with detection accuracy up to 0.1mm; at the same time, we established a customer technical archive library, recording over 2000 sets of production parameters, providing data support for subsequent equipment optimization. The company's technical director said: "The technical competition for fully automatic color tile machines has shifted from single equipment performance to full lifecycle service capabilities. Xinlong Machinery helps customers reduce comprehensive costs by 15%-20% through the closed-loop model of 'equipment + process + after-sales'."

FAQ: Common Technical Questions and Answers

Q1: What are the requirements for raw materials in an automatic colored tile machine?
A: Use ordinary silicate cement with a grade of 42.5 or higher, sand with silt content ≤3%, aggregate particle size ≤5mm, and control the water-cement ratio between 0.35-0.45.

Q2: What is the maintenance cycle for the equipment?
A: Daily maintenance requires cleaning the mold and checking the hydraulic oil level every day; key components (such as hydraulic cylinder seals) are recommended to be replaced every 2 years, and the overall major repair cycle is 5 years.

Q3: Can we produce antique tiles and other irregular tiles?
A: Custom molds supported, but requires redesign of runner structure and adjustment of pressing pressure (usually increased to 1.5-1.8MPa). It is recommended to provide samples in advance for process verification.
