Core Features and Operational Advantages

High-Efficiency Automatic Sliding Table

The defining feature of the ZJ-15K-25K-35K-SB is its automated sliding table system. Powered by a high-torque Taiwan motor, the table moves with smooth, consistent velocity, reducing mechanical wear and ensuring that the workpiece is positioned accurately under the welding head every time. This automation reduces the physical burden on operators and minimizes the risk of human error during the alignment phase.

High-Precision Positioning

In high-frequency welding, the alignment of the electrode and the material is critical to achieving a hermetic seal. The ZJ-15K-25K-35K-SB utilizes advanced mechanical stops and precision guides to ensure that the sliding table reaches the exact welding coordinates. This high-precision positioning is essential for complex products such as medical bags, automotive interiors, and specialized packaging where tolerances are tight.

High Power Output for Heavy-Duty Applications

With an output range of 15 kW to 35 kW, this machine is capable of handling large-area welds and thick multi-layer materials that lower-powered units cannot process. This high power reserve ensures that the machine operates well within its thermal limits even during continuous shifts, extending the lifespan of the high-frequency oscillation tube and other internal components.

Material Compatibility and Application Scope

The ZJ-15K-25K-35K-SB is a versatile platform for high-frequency welding, but its performance is highly dependent on the dielectric properties of the materials being processed. While it is commonly used for PVC, PU, and EVA-based films and sheets, the specific material set for each machine is not fixed in the standard record. Zhenjia Machine requires a thorough review of actual material samples, including shell components, cards, or films, to ensure the tooling and power settings are optimized for the specific application.

Regional Installation and Site Requirements

For clients operating in Malaysia, Indonesia, and Vietnam, Zhenjia Machine provides specific guidance to ensure the ZJ-15K-25K-35K-SB integrates seamlessly into local factory environments. The recorded supply voltage is 380 V, but site-specific conditions must be verified before shipment.

• Voltage Stability: Industrial power grids can experience fluctuations. It is recommended to confirm if a dedicated voltage stabilizer is required to protect the sensitive electronic components of the HF generator.
• Environmental Controls: High-frequency equipment generates heat and can be sensitive to high humidity. Proper ventilation and moisture control around the electrical cabinet are necessary to prevent arcing and component failure.
• Grounding and Safety: A verified factory earth ground is mandatory for the safe operation of HF equipment. This must be confirmed by a qualified electrician before the commissioning process begins.
• Pneumatic and Hydraulic Supply: Depending on the specific configuration of the sealing head, the machine may require a stable air or hydraulic supply. Pressure and consumption rates should be cross-referenced with the installation data sheet.

Pre-Quotation Configuration Checklist

To provide an accurate quotation and ensure the machine meets production goals, the following information must be reviewed:

1. Detailed material specifications and sample drawings.
2. Required tooling dimensions and the working envelope of the sliding table.
3. Target output per hour and the intended shift pattern (e.g., 8-hour vs. 24-hour operation).
4. Local site voltage, frequency, and the availability of compressed air or hydraulic power.
5. Specific certification requirements for the destination country, such as SIRIM (Malaysia), SNI (Indonesia), or QCVN/TCVN (Vietnam).

Safety Protocols and Routine Maintenance

Operating high-power high-frequency equipment requires strict adherence to safety protocols to protect personnel and equipment.

CRITICAL SAFETY NOTICE: Before performing any maintenance, changing tooling, or clearing material jams, the main power supply must be isolated and locked out. Residual pneumatic or hydraulic pressure must be bled from the system. Only trained technical personnel should access the interior of the electrical cabinet or make adjustments to the sealing head.

• Verify the functionality of emergency stop buttons and safety interlocks at the start of every shift.
• Regularly inspect all pneumatic and hydraulic lines for signs of wear or leakage.
• Maintain the cleanliness of the electrode, sealing head, and platen to prevent carbon buildup and arcing.
• Adhere to the manufacturer schedule for lubrication, filter replacement, and electrical inspection.
