Core Market & Technical Differentiation
- Clearly differentiated from other painting lines in your project portfolio
- Difference from Bumper Painting Line: Bumper lines are customized for large-size automotive exterior parts; Plastic Painting Line is for general small & medium plastic parts, multi-model flexible switching, stronger versatility and wider application.
- Difference from Two-wheeler Painting Line: Two-wheeler lines focus on high-gloss exterior parts with strict metallic texture; Plastic Painting Line balances matte, semi-gloss, solid color and functional coating, suitable for both appearance and internal plastic parts.
- Difference from UV Coating / UV Paint Line: Adopts traditional thermal curing instead of UV instant curing; supports full solvent-based and water-based paints, no restriction on UV-specific materials, lower material cost and wider paint compatibility.
It supports multi-variety, flexible batch production for industrial plastic parts, home appliance casings, 3C components, daily plastic products and automotive interior plastic parts. Equipped with electrostatic rotary atomizer spraying, constant-temperature clean spraying environment and staged hot-air curing process, it solves common plastic coating problems such as poor adhesion, easy static dust absorption, low paint utilization and easy deformation, achieving stable and high-quality mass production.

Core Features and Advantages
1. Powerful Multi-plastic Compatibility This line is optimized for PP, ABS, PC, PC/ABS, PS, PA and blended plastics. It adopts targeted activation process for low-surface-energy plastics, realizing universal adhesion applicability for almost all industrial plastic materials.
2. Anti-deformation Gradient Curing Technology Different from high-temperature metal curing lines, it adopts low-temperature gradient heating mode to avoid internal stress and warping, specially designed for thin-wall and easily deformed plastic workpieces.
3. Professional Static & Dust Control System Plastic parts are easy to generate static electricity and absorb dust. The whole line is equipped with full-process static elimination device and high-grade dust-free booth, effectively reducing particle defects and improving finished yield.
4. Universal Paint Adaptability Supports solvent-based paint, water-based paint, matte paint, metallic paint, ordinary decorative paint and functional protective paint, without limited to UV-specific coatings.
5. High Flexible Modular Structure Able to switch between small-batch customized production and large-scale mass production, compatible with various irregular, small and medium-sized plastic parts.
6. Cost-effective General-purpose Coating Solution Compared with dedicated automobile or UV lines, it has lower investment cost, wider application and lower requirement for special paint materials, suitable for most general plastic finishing scenarios.

FAQ
What kinds of plastic materials can this line handle?
It is compatible with most common industrial plastics, including PP, ABS, PC, PC/ABS, PS, PA and plastic blends. For low-surface-energy materials like PP and TPO, plasma or flame activation is equipped to guarantee reliable coating adhesion.
What types of paint are supported?
It works with solvent-based paint, water-based paint, metallic paint, pearl paint, matte paint and general protective paint. Different from UV lines, it requires no special UV coatings, with wider paint selection and lower material cost.
What kind of workpieces is this line suitable for?
Mainly for small and medium-sized plastic parts, such as home appliance housings, 3C electronic components, automotive interior trims, daily plastic products and industrial casings. It is not specially customized for large automotive bumpers or motorcycle exterior parts.
Why adopt gradient thermal curing instead of constant high temperature?
Plastic parts are prone to thermal deformation and warpage. The multi-stage low-temperature gradient heating design effectively reduces thermal stress, keeps workpieces intact while ensuring full paint curing.
How to solve the problem of easy dust adsorption on plastic surfaces?
The whole line is equipped with full-process static elimination devices and ion air showers, which reduce surface static voltage below 200V. Combined with ISO Class 8 dust-free spray booth, particle defects are greatly controlled.
