Introduction


As China's manufacturing industry moves towards high-quality development, green, intelligent, and efficient production has become the key to competitiveness. Anjia Coating, a leading provider of integrated industrial coating solutions, always adheres to the principle of driving customer value through technological innovation.

In partnership with XCMG, Anjia undertook the pre-treatment line production, which not only showcased Anjia's technological strength and engineering expertise, but also set a benchmark for the green and intelligent upgrade of China's construction machinery manufacturing.


Client Background: XCMG’s Demand for Manufacturing Upgrades


XCMG is a global leader in the construction machinery industry, with a product portfolio covering cranes, road machinery, sanitation equipment and so on. The company places great emphasis on product quality and coating durability. With the establishment of a new plant, XCMG required a pre-treatment line capable of meeting international environmental standards, ensuring reliable operation, and adapting to various structural components to support high-volume production while guaranteeing top-level quality.

Against this backdrop, XCMG partnered with Anjia Coating to build a new-generation pre-treatment line.


Project Overview: Combining Green Solutions with High Efficiency


The core objective of this project was to establish a line capable of processing sanitation equipment components — such as road sweepers, garbage compactors, and hook-arm trucks — through rinsing, degreasing, silane treatment and so on.

Anjia Coating delivered a tailored solution based on XCMG’s production characteristics and site conditions.

Project Highlights:

High Adaptability: supports components up to 8000×2600×3000mm in size and 6000kg in weight, covering a wide range of large structural parts

Energy-Saving & Eco-Friendly: designed in strict accordance with national and industry standards, equipped with advanced heat exchange systems, low-NOx burners, and water recycling processes to ensure emissions compliance

Intelligent Control: fully integrated with PLC systems and MES connectivity, allowing real-time process monitoring, automatic dosing, water replenishment, and seamless data transmission

Reliability & Durability: built with stainless steel and insulated steel structures, with robust anti-corrosion measures to ensure long-term stable operation

This solution not only addressed XCMG's challenges in production efficiency and component flexibility, but also laid a solid foundation for future development in green and intelligent manufacturing.

Process Analysis: Excellence in Every Detail


1. Comprehensive Pre-treatment Workflow


Manual High-Pressure Cleaning: removes large contaminants from workpieces

Spraying Degreasing: conducted at 50–60℃ with an oil-water separation system to ensure complete surface degreasing

Multi-stage Rinsing & DI Rinsing: designed with counterflow water systems to minimize consumption while maintaining high cleanliness

Silane Treatment: performed at 20–30℃ to enhance coating adhesion and corrosion resistance

Manual Blow-off: high-pressure compressed air ensures workpieces are fully dry before entering the coating stage


2. Energy-Saving and Environmental Features


Stainless steel spraying piping and filtration systems to reduce maintenance needs

Wastewater routed through oil separators and treatment stations, meeting GB16297-1996 emission standards

Low-NOx gas heating systems (≤30mg emissions), compliant with environmental standards


3. Smart Control System


Automatic monitoring & dosing: real-time measurement and adjustment of PH, conductivity, and alkalinity

Safety interlocks: full coordination with conveyor systems to prevent operational risks

Remote connectivity: provides integration capabilities for digital factory upgrades


Project Outcomes: Efficiency and Quality Upgrades


Since its commissioning, the project has delivered tangible benefits:

  1. Higher Production Efficiency: reduced time to 8 minutes per hanger, significantly boosting throughput

  2. Improved Product Quality: workpiece surfaces are cleaner and more uniform, with coating adhesion and anti-corrosion performance reaching international standards

  3. Environmental Compliance: energy consumption lowered; waste gas and wastewater fully compliant with national environmental regulations

  4. Reduced Operational Costs: optimized design and automation lowered maintenance requirements and long-term expenses

The success of this project highlights Anjia Coating’s ability to deliver practical value while helping XCMG gain stronger market recognition.
