2.Small temperature difference range, strong controllability, and less prone to product burns

3.Smooth operation

4.Adopts multiple surface treatments such as electrostatic spraying and hard chrome plating, beautiful appearance and durable

5.Suitable for manufacturers who want to invest in low-cost, small-batch production of liquid filter bags for the first time

The hot air nozzle heats the fabric material with hot air and is used for welding heating. The hot air nozzle can heat a specific area of the fabric through a concentrated and uniform hot air flow to achieve the required temperature and effect, and then cool and solidify through the pressing wheel to complete the welding of the middle seam of the filter bag.

Welding process

1. Feeding:

It is to manually feed the raw material of PP fabric into the machine for processing.

2. Welding:

Welding is to weld the middle seam of the fabric together by heating, pressurizing or a combination of both.

3. Solidification

The seam of the fabric filter bag solidifies during the feeding and cooling process of the roller.

Packing and delivery：After the machine is manufactured, welded and tested, it is packed and shipped with fumigation-free wood boards to ensure smooth export.

Advantages

1.Low Initial Investment: Compared to other welding technologies, the hot air melt welding machine requires a relatively low upfront investment, making it ideal for new or startup companies with a limited budget.

2.Simple Operation: The machine is easy to operate, with a user-friendly interface that typically requires minimal training, reducing the likelihood of operational errors.

3.Ideal for Mass Production: This machine is highly efficient, capable of handling large volumes of production, ensuring stable and high-efficiency manufacturing of liquid filter bags.

4.Space-Saving Design: Hot air melt welding machines are typically compact, taking up less space in production environments, which is perfect for facilities with limited space.

5.High Efficiency: With fast heating and welding capabilities, the hot air welding process speeds up production cycles, improving overall manufacturing efficiency.

6.Reliability and Durability: The technology ensures strong, durable seams, making the filter bags more reliable for liquid filtration applications.
