1. Full‑automatic turn‑key coating line for construction machinery excavator parts, covering complete workflow from loading to unloading.
2. The whole process includes loading, pre‑degreasing, degreasing, multi‑stage rinsing, silane treatment, DI‑water rinsing, water‑drying, spray painting, flash‑off, paint curing, forced cooling and unloading.
3. Pneumatic balance hoist is adopted for workpiece unloading to effectively reduce labor intensity for operators. Custom‑built to meet Caterpillar heavy‑duty anti‑corrosion standards.
Application
1. Custom surface treatment solution for heavy‑duty excavator structural parts such as chassis, boom and bucket.
2. Complete production workflow: Loading → Pre‑degreasing → Degreasing → Rinsing → Rinsing → Silane Treatment → DI‑Water Rinsing → Water Drying → Spray Painting → Flash‑off → Paint Curing → Forced Cooling → Unloading.
3. Pneumatic balance hoist is equipped at the unloading station, which greatly lowers workers’ physical labor.
4. Process meets Caterpillar’s strict anti‑corrosion specification for off‑road construction machinery for mass continuous production.
Core Advantages
1. Mature full‑process layout for heavy metal workpieces; silane surface treatment replaces traditional phosphating for environmental‑friendly conversion coating.
2. Integrated water‑drying oven, painting booth, flash‑off zone and paint curing oven to guarantee stable coating quality for complex inner‑cavity parts.
3. Pneumatic balance hoist for unloading station, easy for heavy‑part handling and reduces operator fatigue.
4. Complete safety interlock system, energy‑saving heating design. We provide one‑stop service: process design, manufacturing, site installation, commissioning and staff training.
Industry Scope
This customized coating production line is developed for Caterpillar excavator component manufacturing. It is also widely suitable for construction machinery accessories, heavy truck parts, engineering equipment structures and metal fabrication industries with high anti‑corrosion and appearance requirements.
