Complete Turnkey Coating Line Solutions for Various Industries

Chuangzhi Coating


In industrial manufacturing, the coating line, as the core link of product surface treatment, directly affects product quality and production efficiency. However, different industries have significantly different coating requirements: automotive parts need coatings with salt spray resistance and impact resistance; home appliances pursue extreme appearance consistency; the furniture industry values the texture expression and environmental protection of coatings. The traditional mode of purchasing equipment in segments often leads to delayed commissioning and cost overruns due to poor compatibility and mismatched processes. As a professional coating line equipment manufacturer, we focus on turnkey coating lines, providing one-stop solutions from demand research to commissioning and operation for customers in multiple fields through full-process coating integration and industry-customized coating solutions, ensuring that the coating line accurately matches industry characteristics.
turnkey coating lines

1. Automotive Industry: Building High-Protection Coating Lines with Strict Standards

The coating quality of automotive parts is directly related to vehicle safety and durability. Our turnkey coating line customizes three core modules for the industry:
  • Pretreatment system: Adopts a multi-tank process of "pre-degreasing + main degreasing + phosphating", combined with high-temperature spraying (60-65℃) and precision filtration devices to remove oil and oxide layers on the workpiece surface. The phosphating film thickness is controlled at 2-5μm, laying a foundation for coating adhesion;
  • Electrostatic spraying workstation: Equipped with 6-axis robots and high-voltage electrostatic generators (60-80kV), for special-shaped parts such as chassis brackets and door trim panels, 3D visual positioning achieves precise spraying, with coating thickness deviation ≤±3μm, meeting the 1000-hour salt spray test standard;
  • Low-temperature curing oven: Uses segmented temperature control (160-180℃) to adapt to automotive-specific epoxy powder coatings, ensuring complete curing while avoiding workpiece deformation caused by high temperatures. A single production line can achieve a daily output of 2000 pieces.
 
After a new energy auto parts factory introduced this solution, the coating defect rate dropped from 12% to 1.8%, and the commissioning cycle was shortened by 40% compared with the traditional mode.

 

2. Home Appliance Industry: Achieving Appearance Consistency with High Efficiency and Flexibility

Home appliances (such as refrigerators and washing machines) have high requirements for coating uniformity and color difference control. The industry-customized coating scheme meets the needs through three technological innovations:
  • Fully automatic dust-free spraying booth: Adopts positive pressure air supply and high-efficiency filtration system (Class 1000 cleanliness) to avoid coating defects caused by dust pollution. Combined with online color difference meter (ΔE≤0.8) for real-time monitoring, ensuring uniform appearance of products in the same batch;
  • Quick color change system: Designed for the multi-color needs of home appliances, with automatic pipeline cleaning and powder recovery devices, color change time is shortened from 30 minutes (traditional) to 8 minutes, supporting more than 10 color changes per day;
  • Lean layout design: Connects pretreatment, spraying and curing links into a U-shaped flow line, reducing floor space by 25%. At the same time, the MES system realizes dynamic production scheduling, with a single-shift capacity increased to 3000 pieces, adapting to the mass production needs of the home appliance industry.

3. Furniture Industry: Balancing Aesthetics and Compliance with Environmental Processes

Furniture coating needs to balance decoration, environmental protection and wood characteristics. Our full-process coating integration scheme specifically solves three pain points:
  • Water-based coating dedicated line: Equipped with low-pressure air spray guns and constant temperature and humidity spraying booths (humidity 50-60%), avoiding sagging or bubbles of water-based paint caused by environmental fluctuations, with coating adhesion reaching 0 level in cross-cut test;
  • Special-shaped parts spraying module: For carved furniture and curved chair legs, 5-axis robots combined with rotating tooling achieve 360° dead-angle-free spraying, increasing coating coverage in pattern grooves from 80% to 99%;
  • VOCs zero-emission system: Integrates activated carbon adsorption + catalytic combustion devices, reducing organic waste gas emissions to ≤20mg/m³, meeting the strictest environmental protection standards in the furniture industry and helping customers pass EIA acceptance smoothly.

 

4. Full-Process Turnkey Service: Worry-Free Experience from Drawing to Commissioning

A complete turnkey coating line solution goes beyond equipment delivery, including full-cycle support:
  • Preliminary planning: Technical teams are dispatched to customers' workshops to issue customized plans including equipment layout, process parameters and energy consumption calculation based on workpiece characteristics, production capacity requirements and space conditions, avoiding the passive situation of "modifying the workshop for equipment";
  • Installation and commissioning: Professional engineers are stationed on-site for installation, synchronously conducting equipment linkage tests and process optimization, ensuring core indicators such as spraying accuracy and curing effect meet standards before delivery, with an average commissioning cycle controlled within 15 days;
  • After-sales guarantee: Provides 1-year free maintenance and lifelong technical support, equipped with a remote operation and maintenance system to monitor equipment status in real time. In case of abnormalities, responses are made within 30 minutes, and downtime is controlled within 4 hours/month.

 

Conclusion

The core value of complete turnkey coating line solutions for various industries lies in "precise adaptation" and "whole-process worry-free". Whether it is the high protection requirements of the automotive industry, the appearance consistency requirements of the home appliance industry, or the balance between environmental protection and decoration in the furniture industry, we can ensure that each customer obtains an "efficient upon commissioning" experience through the flexibility of turnkey coating lines, the systematicness of full-process coating integration, and the pertinence of industry-customized coating solutions. Up to now, we have provided customized solutions for 500+ enterprises, covering 12 sub-industries, helping customers increase coating efficiency by 40% and reduce operating costs by 25% on average. Choosing a professional turnkey partner makes the coating line a core engine for enterprises to improve quality and efficiency.
