1. Case Background & Problem Description
The client is a professional industrial motor manufacturer supplying motors for new energy vehicles since 2023. It faced severe label curling and peeling failures: the motor operating temperature reaches 145°C, which softens the adhesive of ordinary PVC labels. Combined with continuous motor vibration, labels peel off within one month.
This defect broke product traceability and failed the strict quality standards of automotive OEMs. Previous suppliers could only provide labels resistant to maximum 80°C, unable to meet high-temperature working conditions.
2. Industrial-Grade High Temperature Resistant Label Solution
Baihengyu’s technical team analyzed the extreme working environment with dual challenges of high heat and mechanical vibration, then launched a dedicated high-temperature resistant labeling system:
- Flame-Retardant High-Temp Substrate: PVC material withstands up to 180°C with oxygen index ≥32%.
- Silicone High-Temperature Adhesive: Adhesive retention rate ≥90% at 150°C to maintain strong stickiness under heat.
- Laser Precision Die-Cutting: Burr-free smooth edges to prevent edge lifting caused by vibration.
- High-Temp Ink Printing: 6+4 resin rotary printing ensures text and patterns do not blur under sustained high temperature.
3. Field Test Results & Business Value
After full deployment, labels stay firmly attached to motor housings without curling or peeling even after 6 consecutive months of continuous operation at 145°C.
The procurement director shared: "Our motors passed all OEM quality spot checks with zero label defects. We have become their core supplier, with monthly motor orders increased by 30%."
