Zhejiang‑New‑Build Dry Spray Booth Project for Automotive Interior Parts

I. Project Requirements ‑ Dual Challenges of Environmental‑friendliness and Quality for Automotive Interior Part Production

The cooperating local auto‑parts manufacturer in Zhejiang mainly produces various automotive plastic interior parts for OEM customers. As Class‑A appearance components, automotive interior parts impose strict requirements on spraying‑environment cleanliness, paint gloss and particle control. Conventional wet water‑curtain spray booths generate large volumes of production wastewater and paint sludge, resulting in high operation‑and‑maintenance costs for supporting wastewater‑treatment systems. Humidity fluctuation inside workshops also frequently causes cosmetic defects such as particles and pitting on coated interior parts.

With increasingly stringent domestic environmental‑protection regulations, the client planned to construct a brand‑new high‑standard dry spray booth complete line, to eliminate wastewater‑treatment burdens, stabilize spraying conditions and support flexible multi‑variant production of interior parts. Combined with the client’s factory layout, OEM quality‑audit standards and local environmental‑protection specifications, Attractivechina delivered an integrated solution of complete dry‑spray‑booth line and supporting systems, balancing finished‑product yield, eco‑friendly production and long‑term operation economy.

II. Customized Technical Solution ‑ System Construction of Dedicated Dry‑spray‑booth Complete Line for Automotive Interior Parts

This newly‑built dry spray booth complete line is tailored for spraying conditions of automotive plastic interior parts. It consists of enclosed booth housing, multi‑filtration top‑supply & bottom‑return clean air system, multi‑stage dry paint‑mist capture module, differential‑pressure monitoring & alarm system, linked exhaust and back‑end waste‑gas treatment unit, as well as central‑control monitoring module.

1. Clean Air‑supply System: Adopting multi‑stage‑filtration top‑supply and bottom‑return air structure, it purifies inlet air layer‑by‑layer and stabilizes temperature & humidity inside the booth. It reduces dust ingress and fundamentally lowers defects such as pitting and particles to guarantee Class‑A surface coating quality.
2. Multi‑stage Dry Paint‑mist Capture Unit: Modular labyrinth‑style filter structure achieves high paint‑mist separation efficiency to capture over‑spray paint effectively. A numerical‑display differential‑pressure alarm monitors filter‑element clogging in real time for timely filter replacement. It protects downstream waste‑gas‑treatment equipment and extends the service life of activated carbon. No water is consumed during operation, producing zero wastewater and paint sludge.
3. Safety & Process Matching: The booth is designed with explosion‑proof and anti‑static features to meet safety specifications for auto‑parts coating. Air‑volume and air‑pressure parameters are optimized via flow‑field simulation according to production tact time of interior parts, avoiding secondary paint contamination caused by air turbulence.
4. Intelligent Monitoring Module: Integrated into the complete‑line central‑control platform, it centrally displays booth air pressure, differential pressure and fan operating status, and triggers automatic alarms for abnormal conditions to facilitate unified workshop management.

III. Project Implementation Benefits ‑ Dual‑way Gains in Environmental‑protection, O&M Cost‑reduction and Product Quality

✅ Reduced environmental‑protection and operation‑maintenance costs: The dry‑process solution completely eliminates wastewater and paint‑sludge generation. No water‑treatment chemicals are required. Only filter consumables are produced as solid waste, greatly cutting daily labor and material costs while steadily complying with local emission standards. 

✅ Controlled and improved coating quality: Stable airflow and superior dust‑control inside the booth effectively reduce particle‑related defects on interior‑part coatings, enabling finished products to satisfy OEM appearance inspection criteria. 

✅ Efficient project delivery: The complete line adopts modular prefabrication for short on‑site assembly cycle, well fitting the civil‑work conditions of the client’s existing plant. Attractivechina provides on‑site installation, commissioning and operator training to support rapid full‑line commissioning.

This project serves as a typical reference case of Attractivechina’s newly‑built dry‑coating complete line for domestic automotive interior components.
