Industry: Large Cosmetic OEM/ODM Factory (Suzhou Sunrise Cosmetics Co., Ltd.)
Location: Suzhou, Jiangsu Province, a place where labor is expensive.
Product: Vials of perfumes, 1.5 cm diameter, 8 cm high, PET film wrap.
This Suzhou producer had an excellent product and a solid order pipeline, but the last packaging stage was bringing them down. Three employees were hand-sleeving PET labels at the end of the line, which is a bottleneck that literally could not be scaled. And, to make it worse, the product had to be sealed at the top and bottom, with a small window left unsealed in between, something that can only be done with high-precision sleeving equipment.
And the target output? A set of 80 bottles per minute, which the manual process had no hope of achieving.
The factory required a solution that would automate this complicated shrink sleeving process; without losing precision or presentation standards.
Tengyi’s Customized High-Efficiency Sleeving Solution
To reduce reliance on manual labor and meet the precise sealing requirements for the bottle bottom and cap, Tengyi deployed two independent high-speed automated shrink sleeve labeling lines, featuring a crucial customization: precision control and a newly designed vial bottom-sealing module.
1. The Star: Tengyi Fully Automatic Shrink Sleeve Labeler (2 Units)
Each shrink sleeve labeler is powered by a Panasonic servo motor, ensuring tight, closed-loop motion control. The system, together with Panasonic PLCs and OMRON high-sensitivity sensors, has a steady accuracy of ±1 mm even on speeds as high as 100 BPM.
The combo of stainless steel architecture with aluminum alloy upholds the GMP standards and provides long-term high-speed support.
2. The Innovation: Customized Bottom-Wrapping Module
Here’s where this project really stands out.
Tengyi designed a special bottom-wrapping unit that was placed between the labeler and the main heat tunnel. It pre-sleeves PET film to the bottom of the vial and gives it a partial steam-shrink. This holds the film straight until the vial is pushed into the main tunnel so that the top and body are shrunk without causing wrinkles or misalignments.
3. The Partner: Steam Heat Tunnel + 24 kW Steam Generator
The tunnel features:
- 304 stainless steel frame
- POM slat chain conveyor for stable high-speed movement
- A 24 kW steam generator, with stable steam pressure of 0.4 MPa, sufficient to allow constant production of 100 BPM.
Despite the long distance of 1300km between Guangdong and Suzhou, the after-sales team of Tengyi arrived in time to install, calibrate, and fine-tune the two-stage shrink process on-site.
