Double Station High-Frequency Plastic Welding Machine

Product Introduction

When medical accessory factories produce PVC infusion tube connectors and packaging factories manufacture blister and cardboard composite packaging, they often face problems such as low efficiency of single-station equipment, difficulty matching welding parameters for materials of different thicknesses, sparking caused by mold dust accumulation, and water accumulation in compressed air affecting equipment life. The Double Station HF Plastic Welding Machine adopts a dual-station independent operation design, combined with a stable 27.12MHz high-frequency oscillation system, which can realize synchronous welding of two products of different specifications. With precise air pressure adjustment 100-150kPa, it makes the welding of PVC, EVA and other materials stronger. The equipment is equipped with a digital frequency stabilization module and mold dust warning function, which not only avoids welding deviations caused by voltage fluctuations but also prevents fault losses in advance, adapting to the high-standard production needs of the medical and packaging industries.

Product Features

Independent Dual-Station Parameter Control: Supports synchronous processing of plastic products of different thicknesses and types, no frequent mode switching, greatly improving the efficiency of mixed order processing.

Digital Frequency Stabilization & Anti-Fluctuation: Maintains stable output even with ±10% workshop voltage fluctuation, avoiding virtual welding and leakage welding, and the product qualification rate exceeds 99.5%.

Warning & Automatic Maintenance: Automatically reminds to clean mold dust, and the pneumatic system regularly drains water and lubricates, extending equipment life and reducing maintenance downtime.

Quick Adaptation to Multiple Materials: Built-in 100 groups of common material parameter libraries, combined with high-precision mechanical positioning, novices can operate without professional debugging.

Application Scenarios

Sterile Welding of PVC Medical Accessories: Targeting the welding needs of medical accessories such as infusion tube connectors and drainage bag interfaces, it solves the pain points of easy contamination by manual operation and infirm welding. The dual stations of the equipment improve production capacity, the digital frequency stabilization design ensures welding consistency, and the machine body is easy to clean and disinfect, meeting the medical sterile production standards.

Composite Sealing of Blister and Cardboard: Suitable for the composite packaging sealing of blister and cardboard for food and electronic products, solving the problems of low efficiency of single-station and easy cracking of sealed edges. Precise air pressure control ensures tight sealing, and the voltage fluctuation resistance function avoids packaging damage, helping to improve product packaging texture and shelf life.

FAQ

1.Will parameters interfere with each other when two stations process different products synchronously?

A: No interference. The equipment adopts a dual independent control circuit design. The welding time, air pressure and power parameters of the two stations can be stored and adjusted separately, and the signals do not interfere with each other, enabling stable synchronous processing of two products of different specifications.

2.Is pre-drying required when welding 3mm thick rigid PVC materials?

A: No pre-drying is needed. The equipment optimizes the high-frequency output curve for thick-walled rigid PVC materials. Combined with 1T adjustable pressure, it can directly achieve full fusion of material molecules. The tensile strength of the weld after welding is ≥15MPa, meeting industry standards.

3.Will unstable workshop voltage affect the welding effect of the equipment?

A: No. Equipped with a digital frequency stabilization module, the equipment can automatically compensate for ±10% voltage fluctuation, and the high-frequency output remains stable. Even with voltage fluctuation, the welding quality will not deviate, adapting to the power supply environment of ordinary workshops.

4.Can the threshold of the mold dust warning be adjusted?

A: Yes, it can be adjusted. The threshold can be flexibly set according to the production environment (default 500 welding times). For workshops with more dust, the threshold can be appropriately lowered to trigger the cleaning reminder in advance, avoiding sparking caused by dust accumulation and damaging the mold.

5.Does the automatic maintenance function of the pneumatic system need to be manually activated?

A: No manual activation is required. The system automatically starts a maintenance program every 8 working hours, draining accumulated water and supplementing lubrication for pneumatic components, without manual intervention throughout the process, protecting the pneumatic system from corrosion.

6.Can users without professional debugging experience operate it quickly?

A: Yes. The equipment has a built-in 100 groups of preset parameters for common materials. Novices only need to select the material type and thickness, retrieve it with one key to start production; combined with a visual touch screen and graphic operation guide, they can independently complete the operation within 1 hour.

7.Can the tensile strength of the welded products meet industry standards?

A: Yes, it meets and exceeds industry standards. The equipment adopts a low-loss coaxial oscillator to ensure full fusion of material molecules. The tensile strength of the weld is more than 20% higher than that of ordinary equipment. After welding, products of different materials can pass the industry tensile test.

8.Does the equipment support adjusting the workbench according to custom product sizes?

A: Yes. The workbench adopts a modular adjustable design. By loosening the fixing knobs on both sides, the position of the workbench can be adjusted horizontally and vertically, adapting to the processing of products of different sizes without the need for additional custom workbenches.
