Ultrasonic bonding machines provide an automated alternative to manual labeling, saving garment manufacturers time and money

Turn any garment inside out and you’ll most likely find a wash label. Garment manufacturers use wash labels to communicate specific information to the wearer, such as how to properly wash the garment. Although people are often too busy to check wash labels before throwing garments into the laundry pile, doing so is important for maintaining garment quality. Washing at the wrong temperature, or even washing at all, could be a huge mistake, especially with more delicate fabrics. By providing wash labels, garment manufacturers help save customers from turning their favorite sweaters into something a kitten could wear.

But wash care labels don’t just include washing advice—they also show the type of fabric used to produce the garment. Understanding their clothing’s fiber composition helps wearers take extra care of their garments and alerts them to allergy-inducing fibers. Moreover, wash labels impact purchasing decisions, as environmentally conscious consumers can check the fiber composition and opt for a more sustainable material. Wash labels are also the only way to check if items are dry-clean only. It’s better to discover this beforehand, rather than buying a new garment only to learn you need to spend even more on getting it professionally washed.

How are wash labels manufactured and attached?

Wash labels are usually made from a narrow tape-like fabric known as a ribbon. After printing and drying, labels are cut to customer specifications using a label cutting machine, which can cut up to 18,000 labels an hour. Label cutting machines are suitable for preparing labels for bulk orders and can cut a significantly higher number of labels than manual cutting.

There are three different ways to attach labels to clothing. The first way is to fold them into loops and sew them into garments, giving manufacturers plenty of room to write detailed instructions for garment care. The second is to iron them onto garments using an adhesive strong enough to withstand repeated washing. The third is to fuse them onto clothing using an ultrasonic bonding machine.

Why are wash label ultrasonic bonding machines needed?

Wash label ultrasonic bonding machines apply resin to labels, producing neatly bonded booklet-type labels that do not have to be looped or folded. Applying resin in the form of soldered dots allows labels to be fused to garments without additional sewing, removing the risk of fraying. As a replacement for needle-and-thread sewing, ultrasonic bonding is suitable for delicate materials that could be damaged by needles.

Ultrasonic bonding machines only produce heat when needed, saving energy and reducing the likelihood of overheating. Clothing is protected from damage or scorching from machines that are too hot. Ultrasonic bonding machines are safer for production staff, too, as cooler machines mean a lower risk of burns.

Benefits of ultrasonic bonding machines

  • Ultrasonic bonding machines remove the risk of human error

Manually sewing labels onto garments can result in poorly stitched labels or torn clothing. Furthermore, ultrasonic wash label ultrasonic bonding machines apply labels to clothing in one swift and accurate motion. This removes the risk of human error, allowing manufacturers to consistently turn out high-quality products.

  • Ultrasonic bonding machines improve productivity

Ultrasonic bonding machines are four times faster than ordinary sewing machines, creating seamless fabric bonds in seconds. As factory workers no longer need to spend time aligning and sewing labels into clothing, they can move to other departments, which enhances production efficiency.

Moreover, ultrasonic bonding machines can fuse multiple labels at once, unlike manual bonding where each label is bonded separately. Wash label ultrasonic bonding machines boost production efficiency by speeding up an otherwise slow process, allowing manufacturers to take on larger bulk orders.

  • Ultrasonic bonding machines save time and money

Ultrasonic bonding machines apply the exact amount of heat required to make the perfect fabric bond without overheating. They can start labeling as soon as they have heated up to the desired temperature, so there’s no need to wait for the adhesive resin to melt first. This way, manufacturers save time in the labeling process and avoid the risk of ruining garments by bonding fabric before the resin is adequately heated.

Ultrasonic bonding machines are extremely efficient and can complete the entire label fusing process in seconds. With this automated process, manufacturers don’t have to employ dozens of factory staff, saving additional money on labor costs and boosting overall efficiency.

OSHIMA: Excellence in Multi-label Fusing

With over five decades of garment machinery manufacturing experience, OSHIMA’s expertise is second to none. OSHIMA designed three wash label bonding machines using smart ultrasonic technology. The WLS series is a fully automated labeling system that cuts, aligns, and applies labels in a matter of seconds. The machines have between six to eight labeling stations for maximum production efficiency, and the WLS-302S machine can even attach labels to clothing with a simple line of stitches. With this range, garment manufacturers can speed up the labeling process while leaving little room for error.


Garment wash labels are a small but important part of any garment, providing wearers with key information designed to protect clothing and prolong its life. But the traditional method of manually applying wash labels is far from perfect, being a slow process that is prone to human error. Luckily, garment manufacturers now have an automated alternative. OSHIMA wash label ultrasonic bonding machines bring convenience to the labeling process, creating securely bonded labels in just a few seconds and removing the need for manual intervention.
