5KW Dual-Head Pneumatic High-Frequency Welding Machine

Product Introduction

When mass-producing PVC inflatable toys, leather logos, and other products, you often face problems such as low efficiency of single-head equipment, large manual alignment deviations, weak welding of materials, or unclear embossing, which seriously affect order delivery schedules. The 5KW Dual-Head Pneumatic HF Welder is equipped with a dual-head independent pneumatic structure and adopts the international standard oscillation frequency of 27.12MHz, which can quickly realize the fusion of plastic molecules and the embossing shaping of leather. Equipped with a precise pressure regulation and spark protection system, the equipment can adapt to plastic and leather materials of different thicknesses, not only improving mass production efficiency but also ensuring stable product processing quality, helping enterprises reduce rework costs.

Product Features

Dual-head independent operation, doubled efficiency: The two stations support simultaneous or separate operation, and can set welding/embossing parameters respectively, adapting to mixed orders of multiple product categories. Compared with single-head equipment, the production efficiency is increased by more than 60%, meeting the processing needs from small-batch to large-batch production.

Pneumatic drive + precise pressure control, excellent forming effect: Adopting a pneumatic drive system with stable and adjustable pressure, combined with a stepless heating mold device, the temperature can be adjusted according to material characteristics. The plastic welding seam is firm, the leather embossing pattern is clear, and there are no burrs on the edges.

High-sensitivity spark protection, reducing loss: Built-in NL5557 high-sensitivity spark protection system, which can instantly cut off the high-frequency circuit when encountering material impurities or alignment deviations, avoiding damage to the mold and electron tube, extending the service life of the equipment and reducing material waste.

Easy operation, quick to learn: Equipped with a high-definition touch screen and parameter memory function, it can store 10 groups of commonly used process parameters, eliminating the need for repeated debugging when changing products. The station is equipped with precise positioning scales to assist manual quick alignment, allowing novices to master the operation quickly.

Application Scenarios

Mass Welding of PVC/TPU Soft Plastic Products: Targeting the mass welding needs of inflatable toys, raincoats, soft packaging bags, medical product packaging and other products, it solves the pain points of low efficiency and weak welding prone to cracking of traditional single-head equipment. Through dual-head independent operation, the equipment improves production efficiency. The precise pressure control and heating system ensures flat and firm welding seams, and the spark protection function reduces the defective rate, adapting to the mass production mode of small and medium-sized manufacturers.

Leather/Artificial Leather Embossing & Labeling Processing: Suitable for processing scenarios such as shoe logos, leather bag LOGOs, clothing embossing, and ID card holder creasing, solving the problems of uneven pressure, blurred patterns and low efficiency of manual embossing. With the stable pressure of pneumatic drive and stepless heating mold, the embossed pattern is clear and three-dimensional, not easy to fall off. The dual-head design supports simultaneous processing of different patterns, flexibly adapting to the needs of multi-style orders.

FAQ

Can the two heads process PVC and leather products of different thicknesses at the same time? Can the parameters be saved independently?

Answer: Yes, they can be processed at the same time. The two heads support independent adjustment of pressure, time and temperature parameters, and support 10 groups of parameter memory storage. They can respectively adapt to PVC and leather products of different thicknesses without repeated debugging, adapting to mixed production of multiple product categories.

When processing thin TPU medical packaging, how to avoid the material being scalded?

Answer: The equipment supports low-pressure fine-tuning and short-time welding mode. For thin TPU materials, low pressure and short time parameters can be preset. Combined with the heat insulation treatment of the mold surface, it can effectively avoid material scalding and ensure the sealing performance of the packaging.

After leather embossing, do you need to wait for cooling before taking the product? Will it affect efficiency?

Answer: No need to wait separately. The equipment head is equipped with a rapid cooling device, and the product can be taken within 3 seconds after embossing. Combined with dual-head alternate operation, it can realize seamless connection of "embossing - taking - loading", which will not affect the overall production efficiency.

Can the sensitivity of the equipment's NL5557 spark protection system be adjusted? Is it suitable for processing materials with slight impurities on the surface?

Answer: The sensitivity supports three-level adjustment. For materials with slight impurities on the surface, the sensitivity can be lowered to avoid false triggering. At the same time, the system has a fast response speed and can instantly cut off the high-frequency circuit, which does not affect production and protects the mold from damage.

During mass production, how to ensure the consistent processing effect of the two heads?

Answer: The equipment has completed the parameter calibration of the dual heads before leaving the factory, and supports the parameter synchronous copy function. The debugging parameters of one head can be directly copied to the other, ensuring the consistent processing effect of the dual heads. At the same time, it is equipped with a pressure balance compensation device to avoid differences caused by air pressure fluctuations.

Is the equipment suitable for processing mixed materials containing 30% PVC? Do the parameters need special settings?

Answer: Yes, it is suitable. The equipment is compatible with mixed plastic materials containing more than 30% PVC, and no special settings are required. It has built-in special parameter presets for mixed materials. During processing, you only need to fine-tune the power according to the product thickness, and the welding firmness is consistent with that of pure PVC materials.

After long-term mass production, will the equipment trigger overheating protection and shut down?

Answer: No. The equipment is equipped with an independent forced heat dissipation system and a temperature monitoring device. It can stably maintain the working temperature within 4 hours of continuous operation, and will not trigger shutdown due to overheating, which can adapt to the needs of long-term mass production.

Is it convenient to replace embossing molds of different patterns? Do professional tools need to be used?

Answer: It is convenient to replace without professional tools. The mold is fixed by a quick buckle. The old mold can be removed by loosening the buckle. After installing the new mold, it is calibrated by the positioning pin, which can be completed within 5 minutes, adapting to the rapid switching production of multiple styles.
