Your Manufacturing Demands, Our Integrated Solution

At XHS, we specialize in delivering high-precision, fully integrated equipment for TWS (True Wireless Stereo) pouch-type button cells.

Our Top/Side Sealing, Testing & Trimming Machine combines thermal sealing, integrity testing, and edge trimming into a single streamlined platform — designed to meet the compact scale, strict quality, and high-throughput requirements of modern TWS battery production.

Whether you’re manufacturing for earbuds, smart wearables, or other ultra-compact applications, this solution ensures every cell is sealed, verified, and finished to the highest standards — ready for reliable integration into miniature consumer electronics.

Engineered for Micro-Cell Precision & High-Volume Reliability

Our integrated machine delivers ±1°C temperature control, ±0.1 mm trimming accuracy, and uniform sealing pressure, ensuring every pouch button cell is processed with exceptional stability and repeatability.

From delicate top sealing to side fold sealing, from electrical and air-leak testing to clean edge cutting, each step is optimized to reduce handling, improve takt time, and support mass production with zero-compromise quality.

Top & Side Sealing Applies controlled heat and pressure to precisely seal the pouch film on both the top and side edges, forming a robust barrier that prevents electrolyte leakage and supports compact stacking.

Inline Quality Testing Integrates air-tightness (leak) testing, visual inspection, and optional electrical resistance or short-circuit testing to identify early defects before final packaging.

Edge Trimming Removes excess pouch material with ±0.1 mm precision, ensuring a clean profile and consistent dimensions for module assembly or standalone use.

Compact Footprint & Modular Integration Designed to occupy minimal floor space and seamlessly integrate into semi- or fully-automated production lines for high-volume cell assembly.
