6.Thanks to the foot pedal, your hand are free to guide the material.

 

Use SWT-PAU (or similar brands such as LEISTER) hot air plastic welder to weld the door curtain of PVC fast rolling door:

 

 

一、Prepare the work area:

 

(1)Make sure the work area is clean, flat and windless (wind will affect the hot air temperature and welding effect).

Prepare all tools and materials and keep them at hand.

 

(2)Material preparation and cutting:

 

Accurately cut the PVC door curtain cloth according to the door frame size. The key to butt welding is that the edges of the two pieces of cloth must be cut very straight, vertically and without gaps or burrs. Use a sharp blade and ruler for cutting.

 

If you need to splice multiple pieces of cloth, calculate the size and splicing position.

 

(3)Clean the welding area:

 

Use a non-woven cloth with a cleaning agent (isopropyl alcohol) to thoroughly wipe the front and back of the edges of the two pieces of cloth to be welded (an area about 2-3cm wide). Remove all dust, grease, fingerprints, mold release agents and other contaminants. This step is crucial, stains will cause a weak weld!

 

Wait for the cleaning agent to evaporate and dry completely.

 

(4)Alignment and fixation:

 

Align the edges of the two curtains to be joined closely, ensuring that there is no overlap or gap. Ideally, they should just touch.

 

Use a clamp (heavy clamp, special welding clamp) or high-temperature tape (such as Kapton tape) to firmly fix the two pieces of cloth on a flat workbench, ensuring that the welding area is flat, wrinkle-free and non-shifted. The fixing point is about 5-10cm away from the weld. Alignment and fixation are the basis for successful welding.

 

(5)Welding machine settings and preheating:

 

(6)Install a suitable butt welding nozzle for SWT-PAU.

 

Temperature setting: This is the most critical parameter! The thickness of PVC fast-moving curtains is usually around 0.8mm-1.5mm. Starting reference temperature:

 

Hot air temperature: about 350°C - 450°C (adjusted according to equipment model, ambient temperature, cloth thickness and specific PVC formula). Always test on inconspicuous scrap first!

 

Temperature of the heating plate at the bottom of the welding nozzle (if the welding nozzle has a heating plate): usually lower than the hot air temperature, about 250°C - 350°C, mainly used for preheating materials.

 

Air volume setting: Medium air volume (such as 4-6 gears, depending on the equipment). Too much air volume may blow away the molten material or cool too quickly; too little air volume will result in low heating efficiency.

 

Turn on the welding machine and preheat the welding nozzle to the set temperature (usually takes a few minutes). Do not blow at the material during preheating.

 

(7)Test welding:

 

It is strongly recommended to use the same batch of curtain fabric scraps for test welding before formal welding! Test the same docking method, temperature, speed and pressure. After cooling, tear the test weld hard:

 

If the fabric itself is torn and the weld is intact: it means the welding is successful.

 

If the weld is easily torn: it means the temperature is too low, the speed is too fast or the pressure is insufficient.

 

If the fabric is charred, yellowed, severely thinned or perforated: it means the temperature is too high or the speed is too slow.

 

(8)Formal welding:

 

Wear heat-resistant gloves.

 

Gently place the front end of the preheated welding nozzle (guide block) into the starting end of the joint between the two pieces of cloth.

 

Start the welder: The hot air begins to heat the edges of the two pieces of cloth below.

 

Advance at a constant speed: Move the welder forward along the joint at a steady and constant speed (usually slow, such as 1-3 cm per second, the specific speed is determined by testing). Uniform speed is the key to ensuring consistent weld width and strength.

 

Observe the melting state: Observe the melting of the cloth through the observation window or the back of the welding nozzle. The ideal melting state is that the surface of the material becomes bright and slightly "flowing" but not carbonized. The silicone pressure wheel at the back of the welding nozzle will follow and roll the molten area.

 

Apply appropriate downward pressure: Keep the welder stable and apply slight and uniform downward pressure to the welding nozzle to ensure that the pressure wheel can effectively compact the molten PVC. Excessive pressure will thin the material; insufficient pressure will not fully fuse.

 

Continuous welding: Try to complete the entire weld in one go. If you have to interrupt, when you restart, the welding nozzle should slightly cover the welded part (about 1-2cm) before moving forward.

 

(9)Cooling:

 

After welding, let the weld cool naturally without stress. Do not pull, bend or use water to cool the newly welded area, otherwise it will weaken the weld or cause deformation.

 

Inspection and trimming:

 

After cooling, carefully inspect the weld:

 

Appearance: Is it continuous, uniform, and of uniform width? Are there any burns, perforations, unfused, or bubbles?

 

Strength: Try to tear the sides of the weld by hand (simulating the force of the door curtain) to feel the firmness. The strength of a reliable weld should be close to the fabric itself.

 

If there are small defects (such as small bubbles or slight unfused), you can use a spot welding nozzle or a hot air gun with a small pressure wheel to make local repairs.

 

If there are burns or serious defects, you need to cut off the section of the weld, cut and weld again (very troublesome, so testing and careful operation are important).

 

Trim off excess burrs (if any).
