Zhengzhou, China – Zhengzhou Yishang Machinery Equipment Co., Ltd., a leading manufacturer of construction material packaging solutions, has announced the launch of its latest Dry Mortar Packing Machine featuring integrated Ultrasonic Heat Sealing technology for valve bag packaging.

The new packing machine is engineered to deliver high output capacity of 5-7 tons per hour while ensuring exceptional weighing accuracy of ±0.2%. The integration of ultrasonic sealing technology represents a significant advancement in powder packaging, providing hermetic, moisture-proof closures that prevent product degradation during storage and transport.

Moisture protection and packaging accuracy are critical concerns for dry mortar manufacturers,Our new ultrasonic sealing packing machine addresses both challenges, delivering precise weights and airtight seals that preserve product quality while maximizing production efficiency.

Key Highlights of the New Packing Machine

The ultrasonic sealing system uses high-frequency vibrations to fuse valve bag layers without physical contact, creating a hermetic, tamper-proof closure with no thermal byproducts and no consumables required. This technology is especially critical for hygroscopic materials like dry mortar, gypsum, and putty powder.

The high-accuracy digital weighing system with PLC control and multi-stage feeding ensures consistent bag weights of ±0.2%, minimizing material waste and ensuring compliance with trade standards. The fully sealed design with pneumatic air flotation filling ensures virtually dust-free operation, creating a cleaner and safer working environment.

Technical Specifications

The machine delivers a packing capacity of 5-7 tons per hour, accommodates standard valve bags from 10kg to 60kg, and features a PLC touchscreen control system with recipe storage for easy operation and quick changeovers. The durable construction with wear-resistant components ensures reliable, long-term performance in demanding industrial environments.

The packing machine is suitable for dry mortar plants, cement factories, gypsum processing facilities, and other powder processing operations seeking reliable, accurate, and clean packaging solutions.

With this product launch, Zhengzhou Yishang Machinery continues to demonstrate its commitment to innovation and quality in the construction equipment industry, providing customers with efficient solutions that enhance productivity and reduce operational costs.
