SANDO TECH, Inc. List of Products and Services

We have developed a device for peeling and cleaning ink and coated layers printed on film. By peeling and cleaning inks, etc., from the film (plastic), we contribute to the reuse of the film. *We have a peeling and cleaning testing machine installed in our company, so peeling tests can be conducted at any time. 【Flow of Plastic Reuse】 (1) Peeling and cleaning printed film rolled up in a roll using this device. (2) Pelletizing the cleaned film for reuse (recycling) or reusing it as is (reuse). 【Flow of Coating Layer Reuse】 (1) Peeling and cleaning printed film rolled up in a roll using this device. (2) Collecting the cleaning liquid mixed with the peeled layer and recovering the coating layer through filter filtration. 【Cleaning Process】 Unrolling ⇒ Immersion (cleaning aid) ⇒ Peeling ⇒ Cleaning (water) ⇒ Drying ⇒ Rolling 【Features】 ■ Peeling can be done with minimal scratches due to the peeling roll (patented). ⇒ The film can be reused without repelting after peeling, and it can also accommodate delicate substrates that are prone to breaking. ■ A circulation system is established in the tank, contributing to the reduction of running (disposal) costs for cleaning aids. ■ Compatible with single-sided printing, double-sided printing, and both types of printed films.

This device can quickly and accurately connect the old substrate to the new substrate. The splice operation, which took about 7 seconds with conventional devices (butt joint), can be shortened to as little as 0.5 seconds with this device. As a result, the downtime during the splice operation is reduced, allowing for an accumulator-less splice using only the dancer roll. We have a coating and drying test machine, including the splice device, fully equipped in our clean room (Class 10,000), allowing customers to bring in their substrates for testing. 【Features】 ■ Patented ■ Splice operation shortened to a minimum of 0.5 seconds (joining takes a minimum of 1 second) ⇒ Production can be maximized with the old roll until the last moment, improving productivity ⇒ Allows for downsizing of the accumulator (switching to a dancer) * For more details, please refer to "Benefits of Speeding Up" ■ Both butt joint and overlap are possible ⇒ Butt joint is optimal for connecting laminated substrates ■ Enabled high-speed traverse (cutter operation) for excellent cutting performance ⇒ Can handle fragile substrates and thick materials.

This device removes dirt, dust, sebum, and grease that could not be eliminated by conventional ultrasonic or adhesive methods, using a combination of vibration and water flow (discharge and suction). It creates intense vibrations and water flow (discharge and suction) with a special three-layer structure (patented). The effect is that the liquid in the bathtub remains gentle while generating a synergistic effect of underwater vibrations and discharge/suction on the substrate. As a result, contaminants are dispersed in the bath, allowing for separation and discharge while preventing re-adhesion. The pass line is designed to avoid contact with the basket (punching) to prevent damage to the substrate (film). **Features** - Patented - Combination of vibration, water flow, and microbubbles - Removes dirt and dust, sebum, and grease adhered to surfaces - In the test machine, water is cut off with an air knife after cleaning, allowing for annealing and drying in an annealing furnace. Using microbubbles in conjunction promotes the aggregation effect and floating separation of dispersed contaminants. Additionally, the vibration mechanically breaks the microbubbles, further enhancing the effect. Hybrid means cleaning with both vibration and water flow (discharge and suction). *For more details, please refer to the PDF document or feel free to contact us.*

■ Belt-type Drying and Heat Treatment Machine By placing the substrate on a belt and using the belt to transport the substrate, heat treatment (drying) can be performed at low tension. It can accommodate a wide range of configurations, including bottom belts, upper and lower belt sandwiching, and suction combinations. Our testing machines allow for adjustable nozzle positions, enabling tests in desired arrangements such as opposing upper and lower nozzles or staggered upper and lower nozzles. ■ Floating-type Dryer Drying can be achieved without contact between the substrate and rolls, thanks to the airflow from the blower. This helps prevent unevenness on the coating surface. Options for vertical or horizontal configurations are available, and we can make proposals based on pass line and installation location constraints. ■ Heated Roll Dryer By transporting the substrate with heated rolls, drying and heat treatment of the substrate can be achieved. We can propose cylinder dryers with high efficiency and cost-effectiveness, as well as jacket rolls for annealing purposes, tailored to your specific needs.

This is a two-axis fixed-type unwinding (winding) device equipped with an auto splice function. While the two-axis turret type requires space for rotation, the two-axis fixed type can operate in a space-saving manner. The splicing method uses tape. The splicing methods for the unwinding device can be butt splicing or overlap splicing, and both options are available. The splicing time can be as short as 1 second, allowing for a smaller accumulator. We can propose not only new installations but also replacements for existing lines, so please consider us when contemplating converting an existing single-axis system to a two-axis system.

This is a device that performs the task of removing defects from paper (non-woven fabric) easily and with high quality. It meets the needs of reducing manual labor and ensuring seamless connections without failures. Operating Procedure: Preparation: Detect defect areas using a camera or similar device and stop the line. 1. Automatically cut the base material. 2. Manually set the defect area onto a dedicated winding device and automatically wind it. 3. Automatically cut the base material again and automatically apply adhesive to the tip of the base material using a dispenser. 4. Automatically overlay and attach the base material from step 1 onto the base material with adhesive applied.
