ZJ-15K-ADRB 15KW Four-Station HF Welding Machine

The ZJ-15K-ADRB by Zhenjia Machine represents a significant advancement in high-frequency (HF) welding technology, specifically designed for high-throughput industrial environments. This 15KW four-station machine is optimized for the processing of PET, PETG, and other eco-friendly plastics that require precise thermal management and high-pressure fusion. By integrating a fully automatic robotic arm feeding system with a multi-station rotary table, the ZJ-15K-ADRB minimizes manual intervention, maximizes cycle efficiency, and ensures consistent weld quality across large production runs.

Technical Specifications and Electrical Configuration

Advanced Automation and Design Features

The ZJ-15K-ADRB is distinguished by its automation suite, which is designed to reduce labor costs and improve safety. The four-station rotary design allows for simultaneous loading, welding, cooling, and unloading, significantly reducing the idle time found in single-station machines.

Fully Automatic Robotic Arm Feeding

Unlike traditional manual loading systems, the ZJ-15K-ADRB utilizes a fully automatic robotic arm. This system precisely places material components into the tooling, ensuring perfect alignment before the rotary table indexes to the welding station. This automation not only increases speed but also removes the operator’s hands from the immediate vicinity of the sealing head, enhancing workplace safety.

Four-Station Automatic Fusion and Cutting

The machine is equipped for automatic fusion (熔断), a process critical for PET and PETG materials. This allows the machine to weld and trim excess material in a single cycle, producing a clean, finished edge on blister packs or plastic shells. The 1,200mm table provides ample space for complex tooling and multi-cavity molds, further increasing output per cycle.

Compliance with European Environmental Standards

Zhenjia Machine has engineered the ZJ-15K-ADRB to meet European environmental standards. This includes considerations for electromagnetic interference (EMI) shielding and the use of components that align with modern sustainability requirements for industrial machinery.

Material Compatibility and Application Scope

The ZJ-15K-ADRB is specifically recorded for use with PET, PETG, and other eco-friendly plastics. These materials are often used in the medical, electronics, and consumer goods packaging sectors due to their recyclability. Because PET-based materials require specific frequency stability and pressure to achieve a high-quality bond without degradation, the 15KW output and pneumatic drive of this model are ideally suited for these applications.

Prospective buyers should note that material thickness, film composition, and tooling design will influence the final weld strength. We recommend a full material sample test to calibrate the machine settings for your specific production requirements.

Installation and Site Requirements for International Buyers

For industrial installations in Malaysia, Indonesia, Vietnam, and other international markets, the following site requirements must be verified prior to shipment:

• Voltage and Frequency: The machine is recorded for a 380V supply. Site-specific voltage stability should be confirmed; in regions with fluctuating power, an industrial voltage stabilizer is highly recommended.
• Air Supply: As a pneumatic-driven machine, a stable compressed air source is required. Confirm the required pressure (MPa) and flow rate (L/min) against your facility’s compressor capacity.
• Grounding: High-frequency equipment requires a dedicated, high-quality factory earth ground to prevent interference with other electronic equipment and to ensure operator safety.
• Environmental Control: High-frequency cabinets are sensitive to extreme humidity and heat. Ensure the installation area is well-ventilated and moisture-controlled.

CRITICAL SAFETY NOTICE: High-frequency welding equipment operates with high voltage and pneumatic pressure. Before performing any maintenance, tooling changes, or clearing material jams, the main power must be isolated and locked out (LOTO). All residual pneumatic pressure must be bled from the system. Only trained technical personnel should access the internal electrical cabinet or adjust the high-frequency oscillation components.

Selection FAQ

What is the primary advantage of the four-station design?

The four-station rotary table allows for a continuous workflow. While one station is welding, the robotic arm can be loading the next station, and the previous station can be cooling or unloading. This eliminates the downtime associated with manual loading in a single-station press.

Can this machine handle materials other than PET?

While optimized for PET and PETG, it is compatible with various eco-friendly plastics. However, the frequency (27.12 or 40.68 MHz) and power must be matched to the material’s dielectric loss factor. Always confirm compatibility with a material sample test.

What is the expected production output?

Output is determined by the cycle time, which includes the welding time, cooling time, and the speed of the robotic arm. Because these factors depend on the specific material and tooling, a fixed output rate is not specified; it is calculated based on your specific sample validation.

Maintenance and Routine Inspection

To maintain the longevity of the ZJ-15K-ADRB, a strict maintenance schedule is required:

• Daily: Test emergency stop buttons and safety interlocks. Check pneumatic lines for leaks.
• Weekly: Clean the sealing head and electrodes to prevent arcing. Inspect the robotic arm’s suction or gripping mechanism.
• Monthly: Check the electrical cabinet for dust accumulation and ensure all cooling fans are operational. Inspect the rotary table indexing mechanism for smooth operation.
• Annually: Perform a full electrical safety audit and verify the high-frequency output stability.

four-station hf welding machine: selection and next steps

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