BYD Standardizes Factory New-Vehicle Wash with HyTian TX-380
BYD selected HyTian after multi-round vendor comparisons to standardize new-vehicle washing across multiple factories. The TX-380 configuration delivers paint-safe cleaning, uniform dry-off, and line-rate throughput, giving quality teams repeatable, documentable results prior to inspection and shipment.
Problem
BYD sought a factory-grade wash line that would:
- protect premium paint and coatings at scale,
- achieve uniform dryness to reduce rework before PDI, and
- keep pace with takt during production peaks—while maintaining operations visibility for audits and planning.
Approach
HyTian deployed the TX-380 tunnel as a modular, OEM-ready line with:
- Throughput headroom
- Paint-safe media
- Dry-off quality
- Operational clarity
- Process control
The Client — BYD
BYD is a global technology group founded in 1995, operating across automotive, electronics, renewable energy, and rail transit. With a rapidly growing new-energy vehicle business and a global manufacturing footprint, BYD requires repeatable, paint-safe processes that scale with production.
Challenges
- Protect premium finishes on high-volume lines—no micro-marring or attachment damage.
- Achieve uniform dryness before inspection/film and outbound logistics.
- Keep takt on schedule during peak shifts, with minimal operator intervention.
- Provide operations visibility (counts, status) to support planning and audits.
Why HyTian
After multi-round comparisons, BYD prioritized safety, wash cleanliness, and drying performance. HyTian’s TX-380 tunnel car wash system combines throughput headroom, paint-safe media, and connected controls—adapting to different bay layouts while maintaining consistent quality outcomes.
HyTian’s Solution
- EVA brush media → thorough paint-safe cleaning; durable and low-tangle for consistent performance.
- Q-type dryer modules → HyTian's patented drying system, strong, even dry-off; optional silencing enables comfortable indoor operation.
- 10″ HMI + fault shielding → real-time status and guided triage; non-critical faults no longer stall the line.
- Remote assist → HyTian engineers support diagnostics and guidance without on-site delay, reducing downtime.
- Counters & reports → day / month / total wash counts for QA records and capacity planning.
- Metering pumps + coating program → precise chemistry control; ~103° contact angle improves beading and dry-off.
- Throughput capacity → 50–60 vehicles/hour provides headroom to absorb surges without excessive queues.
Implementation
HyTian’s professional service model reduced risk and kept production flowing:
- Project planning: inquiry → HyTian collects client info and project needs → dedicated engineering team delivers preliminary site selection & layout plan.
- Pre-site works: contract → foundation drawings & construction guidance → foundation acceptance prior to delivery.
- Deployment: factory shipment → installation, commissioning, operator training → final acceptance & handover.
Operational parameters—speed modes and dosing profiles—were tuned during pilot to match soil levels and takt, then replicated across additional bays.
Results
Finish & Compliance
- EVA media and balanced brush geometry maintain paint safety while achieving high cleaning effectiveness.
- Uniform dry-off reduces manual wipe-downs before inspection and protective film application.
- Selection centered on safety, wash cleanliness, and drying performance.
Throughput & Labor
- 50–60 cph capacity provides headroom during shift peaks; speed selection aligns with queue dynamics.
- Predictable cycles streamline staffing and reduce rework.
Operations & Uptime
- HMI diagnostics, fault shielding, remote assist, and counters shorten recovery time and provide clear production metrics.
Water & Chemistry
- Metering pumps optimize detergent/wax use; optional coating enhances hydrophobicity for faster dry-off.
