latest company case about Dongguan Mansheng Automation Equipment Co., Ltd Certifications

Large plastic appliance housings — appliance housings and enclosures, electronic device casings, power tool housings, automotive interior housings and consumer electronics enclosures — are big, visible parts whose surface coating defines the look and perceived quality of the finished product. Because these parts are large and often have complex shapes with ribs, vents and recesses, coating them evenly and at speed is challenging. Manual spraying of large housings is slow, tiring and inconsistent. For manufacturers of plastic appliance housings, adopting a high-speed automated robotic spraying solution is a practical way to coat large parts uniformly while keeping production moving.

The Challenge: Fast, Uniform Coating on Large Plastic Appliance Housings

Large plastic appliance housings are produced in many sizes and colors, which makes coating quality hard to stabilize. Factories relying on manual spraying typically struggle with:

• Uneven film on large surfaces: Operators find it difficult to keep a uniform coating over large housings with ribs, vents and recesses, causing thin spots, runs or uneven gloss.
• Slow, tiring manual work: Spraying large parts by hand is physically demanding, and speed varies through the working day, limiting output.
• Color difference between batches: Spray distance, speed and paint feed vary with each operator and session, so the same color can look different between batches.
• High reject rate on large parts: Defects such as orange peel, pinholes and dust marks scrap expensive housings and inflate production cost.

The Solution: High-Speed Automated Robotic Spraying on a Ground-Mounted Line

To meet the finishing requirements of large plastic appliance housings, manufacturers can adopt a high-speed automated robotic spraying solution built on a fully customized, ground-mounted automatic spray painting production line. The conveyor configuration, spray station count and layout are engineered around the customer’s part sizes, paint system and target output.

Key equipment features applied in this appliance coating scenario:

• High-speed robotic spraying: Fast, stable robotic trajectories coat large housing surfaces evenly and keep cycle times short.
• Dual gun stations with closed-loop control: Dual independent guns with stepper drive achieve ±0.05mm positioning accuracy for consistent coating quality on every part.
• Integrated conveyor automation: Seamless belt or roller conveyor with custom length moves large housings through the line and reduces manual handling.
• Stored programs for quick changeover: The Mansheng touch screen control platform stores 10,000+ coating programs, so parameters for different housing models and colors can be recalled instantly via USB communication.
• Industrial-grade components: Core parts sourced from leading brands such as Leadshine, HIWIN and NSK ensure long-term reliability under continuous production.

Results Manufacturers Can Expect

With high-speed automated robotic spraying, appliance housing manufacturers move from operator-dependent finishing to controlled, repeatable coating:

• Uniform, consistent finish: Fixed spraying parameters eliminate manual variation, reducing thin spots, runs and color difference across large surfaces.
• Higher output with less labor: Automated spraying keeps pace with production targets while reducing reliance on skilled painters.
• Lower reject rate: Stable film thickness and fewer coating defects mean less scrap of expensive housings.
• Fast model and color changeover: Stored programs allow quick switching between housing models, supporting mixed production.
