Packaging & Delivery

 

ZJ-8K-10K-AGRB Three- or Four-Station HF Welding Machine

The ZJ-8K-10K-AGRB represents a significant advancement in automated high-frequency (HF) welding technology. Engineered by Zhenjia Machine, this pneumatic-driven system is designed to meet the rigorous demands of high-volume industrial production environments. Available in both 8 kW and 10 kW configurations, the machine utilizes a rotary table design with either three or four stations to maximize throughput and operational efficiency. By integrating sophisticated PLC controls and automated unloading mechanisms, the ZJ-8K-10K-AGRB minimizes manual intervention, ensuring consistent weld quality and reduced labor overhead.

Automated Efficiency and PLC Control

At the core of the ZJ-8K-10K-AGRB is a fully automated PLC (Programmable Logic Controller) system equipped with a user-friendly touchscreen interface. This control architecture allows operators to precisely manage welding parameters, including cycle times, pressure application, and frequency stabilization. The automation extends beyond the welding process itself; the machine features a specialized three-mechanical hand (robotic arm) system for automatic material picking. This robotic integration eliminates the need for manual unloading, which not only accelerates the production cycle but also enhances workplace safety by keeping operators away from the active welding zone.

Rotary Station Workflow

The ZJ-8K-10K-AGRB utilizes a rotary table to facilitate a continuous production loop. In a three-station configuration, the workflow typically involves one station for manual or automated loading, one for the high-frequency welding and cooling phase, and one for the automated robotic unloading. The four-station variant allows for additional cooling time or secondary processing steps, such as card insertion or multi-layer alignment. The 1,000 mm table diameter provides ample space for large-format tooling, making it suitable for a wide range of plastic welding applications, including blister packaging, medical bags, and automotive interior components.

Material and Application Compatibility

While the ZJ-8K-10K-AGRB is designed for versatile high-frequency bonding, the specific material set is not fixed in the standard record. High-frequency welding is most effective with polar molecular structures such as PVC, PETG, EVA, and certain polyurethanes. Buyers must confirm material compatibility with actual samples (shells, cards, or films) and production tooling. Zhenjia Machine recommends a thorough configuration check to ensure the machine’s frequency (27.12 MHz or 40.68 MHz) and power output are optimized for the specific dielectric properties of the substrate being processed.

Regional Installation: Malaysia, Indonesia, and Vietnam

For industrial installations in Southeast Asia, particularly Malaysia, Indonesia, and Vietnam, specific electrical and environmental factors must be addressed prior to shipment. The standard recorded supply is 380 V, but site-specific frequency and plug standards must be verified.

  • Voltage Stability: Fluctuations in local power grids can affect HF generator performance. Determine if an external voltage stabilizer is required for your facility.
  • Environmental Control: High humidity and heat can impact the electrical cabinet’s longevity. Plan for adequate ventilation and moisture control.
  • Grounding Requirements: Proper factory earthing is critical for HF equipment to prevent interference and ensure operator safety. Verify the earth connection before commissioning.
  • Pneumatic Supply: Confirm that the factory air supply meets the pressure and consumption requirements specified in the installation data.
  • Certification Compliance: Check local requirements for SIRIM (Malaysia), SNI (Indonesia), or QCVN/TCVN (Vietnam) to ensure the equipment meets regional safety and import standards.

CRITICAL SAFETY NOTICE: High-frequency welding equipment generates high voltage and electromagnetic fields. Before performing any maintenance, changing tooling, or clearing jams, you must isolate the main power supply, implement lockout/tagout (LOTO) procedures, and bleed all residual pneumatic pressure. Only trained technical personnel should access the electrical cabinet or adjust the sealing head. Always verify that emergency stops and safety interlocks are functional at the start of every shift.

Maintenance and Routine Care

To maintain the precision of the PLC-controlled ZJ-8K-10K-AGRB, a strict maintenance schedule is required. This includes regular inspection of the pneumatic lines for leaks, cleaning of the electrodes and sealing heads to prevent arcing, and monitoring the cooling system. The robotic arms should be checked for alignment and lubrication according to the manufacturer’s schedule. Keeping the 1,000 mm rotary table free of debris is essential for maintaining the accuracy of the station indexing.

Selection FAQ

What are the primary benefits of the robotic arm system?
The three-mechanical hand system automates the unloading process, which significantly reduces labor costs and increases the safety of the operation by removing the need for manual handling of finished parts.

Can the table size be customized?
The standard recorded table size for this model is 1,000 mm. For larger or smaller requirements, please consult with a Zhenjia Machine engineer to review the layout and tooling envelope.

What is the expected production output?
Output is dependent on the material type, the complexity of the tooling, and the specific cycle times required for a secure weld. It is not a fixed value and must be validated through sample testing.

Does the machine support different voltages?
The recorded power supply is 380 V. Any requirements for alternative voltages must be confirmed during the quotation phase to ensure the internal transformers and components are correctly configured.

HF welding machine: selection and next steps

When comparing a HF welding machine, confirm the material, tooling, cycle time and site voltage before quotation. A HF welding machine should be matched to the actual product, output target and operator model, not only to the machine size.
