Huotong Machinery Shines at Chinaplas 2025 with Fully Servo Electronic Shaft Stand-up Zipper Bag Making Machine!

Huotong Machinery’s Recap of Chinaplas 2025
As the sun set on April 18, Chinaplas 2025 came to a close!

Over the four-day exhibition, we were deeply grateful to all the new clients who stopped by to learn about our equipment and to our loyal customers who made a special trip to our booth. Huotong’s progress and growth are built on your trust and support!

For those who couldn’t attend due to busy schedules or other reasons, let us take you back to Huotong’s exhibition highlights.

Introducing Huotong’s Latest Innovation: The WSD-600D+ Fully Servo Electronic Shaft Multi-functional Zipper Bag Making Machine
This machine is specifically designed for recyclable and mono-material packaging. The demo material featured an outer layer of MDOPE laminated with conventional PE, and even the zipper was made of PE, making the entire stand-up zipper bag fully recyclable.

Key Structural Upgrades:

1. Independent Servo Axis Control – Equipped with 32 independent servos and 13 sealing stations, ensuring timing accuracy within ±0.01 seconds per station.

2. High-Precision Pressure Adjustment – Replacing traditional I-beam support with cylinder-controlled pressure, maintaining 0.02mm axial runout accuracy even at 2000 RPM.

3. Optimized Servo Response – Advanced dynamic algorithms reduce servo response time from 0.1s to 0.02s, guaranteeing sealing performance.

Performance Improvements: Efficiency, Quality, and Energy Savings

Precision Independent Control – A fully synchronized servo algorithm allows 32 servos to operate independently, with 10ms adjustable sealing time per station based on material properties.
Enhanced Temperature Stability – Dynamic thermal technology reduces temperature fluctuations from ±5°C to ±1.5°C, ensuring consistent sealing quality.
Energy Efficiency – 20% lower energy consumption and extended continuous operation for higher productivity.

Core Innovations

Smart Pressure Control – Unlike traditional machines with pressure inaccuracies to deformation or weak seals, this fully servo-driven system enables one-touch pressure adjustment for different materials.
Material-Saving Stop-Feed Mechanism – An innovative cylinder system automatically separates sealing components during pauses, preventing material compression and heat damage.
Fully Servo Sealing Technology – Each sealing blade is independently adjustable, allowing operators to customize settings for different products.

Additionally, this machine features one-touch automatic blade positioning with memory function. Once settings are saved, reorders can be processed with a single click, automatically adjusting to the recorded positions.

Huotong’s fully servo electronic shaft bag-making machine drives industry advancement, overcoming technical challenges in mono-material packaging.
