The Tinh Bien International Trade Fair 2026 is witnessing strong attraction at the booth of Vietsonic. Not just visiting, businesses from the food, pharmaceutical, garment, and plastic processing sectors brought their products directly to test the technology.

Despite operating in different industries, most businesses face common “pain points” regarding cost wastage, product quality, and productivity. Below are the top 3 practical issues of greatest concern and how ultrasonic technology resolves them:
1. The Pain of Leakage, Open Seams & Toxicity from Glue (Packaging, Food, Medical, Components Industries)
Customer asks: “We vacuum-pack food, but the bag edges get greasy/wet, so heat sealing often leaves open seams. Meanwhile, in traditional manufacturing of plastic/medical components, using plastic glue is toxic and easily peels, causing water leaks. Can an ultrasonic welding machine solve this?”
Vietsonic answers: Resolved thoroughly and with absolute safety! Ultrasonic waves completely eliminate the risks associated with heat and chemicals (glue).
For the food packaging industry: Extremely fast ultrasonic vibrations will instantly “knock out” all impurities (grease, spices, water) from the sealing area. Bag edges are 100% tightly sealed even in wet conditions, without shrinking the nylon edges.
For the components and plastics industry: Not a single drop of glue is needed. Ultrasonic power causes the two plastic surfaces to self-friction and “melt” together from the inside in just 1 second. The weld achieves rigidity and leak resistance equivalent to the original solid plastic structure, while eliminating a toxic chemical environment for workers.
2. The Pain of Trapped Capital, Sediment & Nutrient Loss (F&B, Cosmeceuticals, Agricultural Products Industries)
Customer asks: “The process of macerating herbs and making traditional wine ‘traps’ capital from a few months to a year; the soaked residue disintegrates and creates a lot of hard-to-filter sediment. Meanwhile, stirring cosmetics or nut milk with regular machines uses heat, causing nutrient loss and easy separation. Can ultrasonic optimize this?”
Vietsonic answers: Vietsonic’s Ultrasonic Stirring – Extraction – Homogenization technology is precisely the “time machine” that helps businesses shorten the process from years down to a few hours, adhering to the 3 No’s criteria:
No time wasted & No sediment: Ultrasonic “cavitation” forces tear plant cell walls to extract medicinal properties/flavors at super speed. Because the time is so short, the raw material residue retains its shape and does not disintegrate into sludgy sediment. For cosmetics or beverages, sound waves tear matter particles down to microscopic sizes, forcing oil and water to blend without separating.
No heating: The entire essence extraction process takes place at low temperatures. Nutrients, vitamins, and natural flavors are 100% preserved, not degraded or discolored like boiling methods. Businesses cycle capital extremely fast, while product quality skyrockets.
3. The Pain of Scrap & Waste in Shaping/Cutting (Apparel, Confectionery, Rubber Processing Industries)
Customer asks: “My garment factory spends a lot of labor on overlocking because cutting fabric with mechanical knives often frays the edges. The confectionery factory experiences crumbled cuts that stick to the knife, causing product waste. What’s different about the ultrasonic knife?”
Vietsonic answers: The difference lies in the fact that the cut edge is “locked” instantly. The ultrasonic cutting knife vibrates tens of thousands of times per second, creating a smooth cutting capability.
For the apparel/non-woven fabric industry: The ultrasonic friction process will seal the fabric fibers right at the cut. The cut fabric is perfectly smooth and permanently fray-free, helping the factory completely eliminate the costly overlocking stage.
For the food industry (Confectionery, cheese): The cut slices are perfectly flat, produce no crumbs, maintain the structure and shape of the finished product, and elevate the aesthetic appeal of the outgoing product.
