SANDO TECH, Inc. List of Products and Services

The "NEO-PERCLER" is a PVA recovery device that can selectively recover PVA, the main cause of COD in wastewater, and can almost completely remove it. It is very economical as the recovered PVA from dyeing processing plants can be reused in weaving factories. The operation is very simple, and it requires almost no maintenance. 【Features】 ■ Can recover over 90% of PVA ■ Can recover only PVA from wastewater containing starch, CMC, acrylic, and oil ■ Very easy to operate, with minimal maintenance required ■ Can use recovered PVA in combination with starch ■ Yarn made from recovered PVA is flexible and suitable for AIR JET LOOM *For more details, please refer to the PDF document or feel free to contact us.

"SANJET" is a gas fluff burning machine that can be used on various types of fabrics, including natural fibers such as cotton and synthetic fibers. It can utilize various heat sources such as natural gas, city gas, LPG, and butane gas, and the complete combustion flame uniformly and thoroughly removes fluff. Additionally, when the machine is stopped, the automatic burner reversal function prevents fabric damage. 【Features】 ■ The powerful high-temperature flame shortens the fluff burning time for processed fabrics. ■ It accommodates a wide range from low to high combustion. ■ Improvements to the burner body stabilize the flame in the width direction, allowing for uniform fluff burning. ■ In addition to nozzle improvements, the automation of air and gas ratio settings reduces gas consumption by approximately 7% compared to conventional methods. ■ Automation through a touch panel increases reproducibility regardless of the operator's experience. ■ It can accommodate various gas sources such as natural gas, city gas, LPG, and butane gas. ■ The separate combustion box has achieved a more compact design for the fluff burning chamber itself.

■ Upgrading Existing Machinery As customers demand new products and quality improvements daily, there may be cases where it is difficult to challenge new processing with the current specifications. We propose effective modification (improvement) methods to make good use of existing machinery. ■ Repair and Improvement of Existing Machinery As machinery operates for many years, it becomes aged and can lead to various troubles. By conducting regular repairs, maintenance, and replacement of consumable parts, our machinery contributes to factory production operations over long periods of 20 or 30 years. Please feel free to contact us for equipment updates, repair work, machinery inspections, etc. 【Service Contents】 ■ Replacement of old equipment with the latest models ■ Energy-saving measures for equipment (reduction of water usage (chemicals), electricity usage, gas usage) ■ Updating control panels (from analog operation to touch panel operation, etc.) ■ Overhauling machinery ■ Replacement of various parts ■ Digitization of equipment (installation of sensors, IoT integration) ■ Checking machinery for defects (maintenance inspections) *We may also be able to support machinery (parts) manufactured by other companies or defunct manufacturers.

The hybrid cleaning machine (vibro washing machine) utilizes a special three-layer structure (patented) that performs intense vibrations and suction while keeping the liquid in the tank gentle. Its effect generates efficient and powerful cleaning (immersion) for the substrate. Additionally, when combined with microbubbles, it promotes the aggregation of dispersed contaminants and their separation, and the vibrations mechanically break the microbubbles, further enhancing the cleaning effect. "Hybrid" means cleaning through both vibration and suction. 【Features】 ■ The combined action of vibration and discharge/suction allows the cleaning water to reach deep into the workpiece, demonstrating high cleaning effectiveness. ■ The intense vibrations of the basket efficiently promote degassing, making it excellent as an immersion device. ■ A three-layer structure with a casing fixed between the basket and runner separates the vibration source from the transport medium, generating a greater vibration effect. ■ The compact washing tank requires only the minimum amount of water, reducing water consumption while providing excellent cleaning effectiveness, and it is also space-saving. *For more details, please refer to the PDF materials or feel free to contact us.

Since the post-war period, our company has been designing and manufacturing continuous dyeing and finishing machines. We are continuously improving and developing our products, and in 1972, we received the first Okouchi Memorial Technology Award in Wakayama Prefecture for our continuous scouring and bleaching machine, "Purple Range." We are also engaged in manufacturing that applies our technological expertise in industrial materials and film machinery, as well as new developments. If you have any new requests, please feel free to contact us.

SANDO TECH develops, designs, manufactures, and sells custom-made Roll to Roll continuous processing machines. In dyeing and finishing machinery, we offer products such as the "SANJET" gas singeing machine and the "PERBLE RANGE" de-sizing, scouring, and bleaching machine. In film processing machinery, we provide splice machines and coating dryers, as well as hybrid cleaning machines in both fields. We will provide optimal proposals using technology that spans multiple fields. 【List by Application (Partial)】 ■ De-sizing, scouring, bleaching, mercerizing, dyeing ■ Film cleaning, film ink removal, coating drying, etc. *For more details, please refer to the PDF materials or feel free to contact us.

We propose winding and unwinding devices according to your requirements. We accommodate various specifications such as single-axis, dual-axis, fixed-axis, and turret types. The substrates we can handle include various materials such as films, metal foils, textile fabrics, and non-woven fabrics (paper). We offer a wide range of solutions, from standalone winding (unwinding) devices to those that include splicing, dancers, accumulators, feeds, and complete line setups. We can also support replacements for existing lines (including those from other manufacturers) and can integrate electrical controls as needed. *For lines from other manufacturers, cooperation from the existing manufacturer will be required. We have a coating and drying test machine, including a splicing device, in our clean room (Class 10,000), allowing us to conduct transportation tests with your substrates brought in.

Our company has been manufacturing various devices that handle liquids, such as coating machines and cleaning machines, and we have also been producing filter devices. We offer custom solutions tailored to various liquids, such as water and solvents, as well as the size of foreign substances to be removed and the usage environment. By performing filtration, we can enable the recycling of liquids, which helps to reduce liquid consumption (energy saving and cost reduction). Examples of applications: Dyeing and finishing: Removing fluff from the water in washing machines Coating: Preventing foreign substances from contaminating solvents supplied to coating machines Peeling: Removing substances separated from solvents and water Pure water production: Filtering industrial water to produce pure water (RO water) In addition to filter devices, we can also provide proposals in conjunction with washing machines, cleaning machines, and coating machines, so please feel free to contact us.

We manufacture various types of coaters, adding features according to the base materials and intended uses. The coating methods include impregnation, gravure, and die, with base materials such as woven fabrics, non-woven fabrics (paper), and films, allowing for a wide range of customization to meet requests. *We have a coating drying test machine installed in our company, so coating drying tests can be conducted at any time. 【In-house Testing Equipment】 ■ Coating Dryer (in Clean Room) Conveying Speed: up to 50 m/min Base Material Width: 250–500 mm Raw Material Diameter: up to 500 mm Tension: 10–200 N Core: 3 inches, 6 inches Coating Methods: Direct Gravure, Reverse Gravure, Pattern Printing, Impregnation, Slot Die Drying Temperature: up to 150°C Drying Method: Roll Support + Floating Dryer (total 5.5 m)
