Equipment Description:

Auto parts Fully automatic spray pretreatment equipment description ‌
(Analysis Based on the 2025 Fully Automatic Surface Treatment Technology Standard)
I. Equipment Description
1. Core use ‌
A fully automatic surface treatment system specially designed for automotive metal parts (such as engine components, body frames, and chassis parts), it achieves degreasing, water washing, phosphating/silanization and other processes through high-pressure spray technology, ensuring the cleanliness and adhesion before spraying or electroplating.
2025 Technology upgrade ‌ : Supports AI dynamic adjustment of spray parameters, suitable for lightweight materials in new energy vehicles (such as aluminum and magnesium alloys).
2.‌ Applicable scenarios ‌
Batch production of auto parts (such as stamped parts, welded parts, and castings), compatible with the flexible production demands of multiple varieties and small batches.
3. Process advantages ‌
Fully automated ‌ : No human intervention throughout the process from feeding → spraying → drying → discharging;
High coverage ‌ : Multi-angle spray to solve the problem of cleaning the inner cavity of complex structural parts;
Environmental compliance ‌ : The wastewater/waste gas treatment system complies with the latest environmental regulations up to 2025 (e.g. VOCs emission limit ≤50mg/m³).
Ii. Highlights of Technological Upgrades in 2025
1. Digital twin operation and maintenance ‌
The 3D virtual model maps the equipment status in real time, reducing the predictive maintenance failure rate by 40%.
Multimaterial compatibility ‌
A new carbon fiber pretreatment mode has been added to address the difficulty of spraying composite materials in new energy vehicles.
2.‌ Green manufacturing ‌
Biodegradable degreasing agents have replaced traditional solvents, reducing COD emissions by 60%.
