Details
The BMC Base Coat Line is a fully automated professional coating production line developed for BMC (Bulk Molding Compound) workpieces. BMC materials are widely used for automotive exterior & interior parts, electrical components and industrial housings, featuring high hardness, good moldability and chemical resistance. This line is dedicated to surface base coating treatment for BMC products, integrating pre-treatment, automatic spraying, IR leveling and drying processes into one complete workflow.
It adopts stable spraying technology matched with BMC material characteristics, forming a uniform, well-adhered base coat layer. The base coat effectively improves surface flatness, covers minor material defects, and lays a solid foundation for subsequent topcoat and functional coating. With eco-friendly process design and intelligent control system, the line realizes continuous, high-efficiency and high-yield production, fully meeting mass manufacturing requirements of BMC parts for automotive, electronics and general industries.
Feature And Advantage
| Advantages | Description |
|---|---|
| Excellent Coating Adhesion | Optimized spraying and IR drying process ensures the base coat tightly bonds to BMC substrate. No peeling, blistering or delamination occurs, and it works perfectly with follow-up topcoats. |
| Uniform & Smooth Coating Surface | Precise quantitative spraying delivers consistent film thickness across complex shapes. It covers surface flaws effectively, creating a flat base for subsequent finishing. |
| Stable Continuous Production | Full automatic line operation reduces manual intervention. The matched conveying and control system ensures stable running, lowers defective rate and boosts overall productivity. |
| Material & Paint Compatibility | Specially adapted to BMC material properties. Compatible with various solvent-based and water-based base paints, supporting different color and process requirements. |
| Energy Saving & Eco-Friendly | Equipped with paint mist collection and waste gas treatment system, low VOC emission. It complies with CE, RoHS and relevant industrial environmental standards. |
| Flexible Customization | Line layout, spraying stations, drying temperature and running speed can be adjusted according to workpiece size, shape and daily output. It fits both mass production and small-batch orders. |
1. Automatic Spraying System: Equipped with reciprocating spray machine or robotic spraying unit, stable spraying trajectory, adjustable paint output and gun distance for BMC parts of various structures.
2. IR Leveling & Drying Zone: PID precise temperature control (Room temperature ~ 100°C). Uniform heating ensures full solvent volatilization and complete drying without damaging BMC materials.
3. Conveying System: Customized conveyor structure, stepless speed regulation, stable transmission suitable for heavy BMC workpieces.
4. Dust Prevention System: Semi-closed or fully enclosed spraying area with multi-stage filtration, preventing dust contamination and guaranteeing base coat quality.
5. Central Control System: PLC + touch screen integrated control, parameter memory, real-time fault alarm and easy operation.

FAQ
Q: How do you guarantee our quality standards?
A: We layer in quality: offline robot programming optimizes spray paths first, SCADA logs every parameter (full traceability), and we can add automated vision checks for 100% surface inspection. One client matched their OEM's strict standards on the first try.
Q: How fast can you set up a car parts paint shop?
A: 3-6 months with modular parts.
Q: Does it work for EV production lines?
A: Yep, it's perfect for EV parts like BYD's, with eco-friendly coating.
Q: How much maintenance is needed?
A: Daily wipe-downs, quarterly checks. Downtime's under 2% with our support.
Q: Can it fit in a small factory?
A: Absolutely. We design compact layouts-even multi-level (mezzanine) setups to save floor space. Our 3D simulation lets you see the layout first, so we maximize output per square meter. A Guangzhou client with a tight space now runs 2 lines where they used to fit 1.
Q: Is this a fully unmanned, "lights-out" factory system?
A: While highly automated for minimal supervision, the system is engineered for operational excellence with strategic human oversight. Tasks like fixture loading, final quality audit, and system monitoring are essential for ensuring ultimate reliability and quality, creating a perfect synergy between automation and human skill.
