Unlike traditional sandblasting, it achieves precise cleaning without damaging the substrate. With low environmental impact and no secondary waste generated after the work, it contributes to improved work efficiency and cost reduction. 【Features】 ■ High-speed jetting of dry ice pellets ■ Precise cleaning without damaging the substrate ■ Low environmental impact with no secondary waste generated after work ■ Significant improvement in work efficiency and cost reduction *For detailed information on the mechanism and benefits of dry ice cleaning technology, please refer to this document.

In high-quality film manufacturing, dirt that adheres to molding lines and rollers is a significant challenge that directly leads to product defects. We achieve complete removal of resin debris and stubborn dirt that adheres to resin film molding lines such as OPP and PET using the power of dry ice, resulting in a clean environment. Since the blast can effectively reach complex drive components and narrow gaps, it significantly reduces the time and effort required to disassemble equipment. By incorporating this into regular maintenance, we strongly support the prevention of production halts and the stabilization of production quality. 【Features】 ■ Complete removal of resin debris and stubborn dirt for cleanliness ■ Blast reaches complex drive components and narrow gaps ■ Significantly reduces the time and effort required to disassemble equipment ■ Strongly supports the prevention of production halts and stabilization of production quality *For case studies demonstrating dramatic cleaning effects in OPP and PET manufacturing lines, click here.

The complex dirt that clings to the fan blades and surrounding equipment can be thoroughly cleaned without damaging the base material using dry ice blasting cleaning services. Compared to traditional manual scrubbing or chemical cleaning, the work can be completed in a short time, minimizing production line downtime. This restores a clean environment and revives the original performance and energy-saving effects of the air conditioning equipment. 【Features】 ■ Thoroughly cleans without damaging the base material ■ Work is completed in a short time ■ Minimizes production line downtime ■ Revives the original performance and energy-saving effects of air conditioning equipment *Here is the comparison of fan equipment before and after cleaning and data on work efficiency improvement.

In conventional grit media cleaning (such as sandblasting), issues such as debris, damage to the base material, and waste disposal have been challenges. The cleaning service using dry ice pellets does not leave the cleaning media on-site because the dry ice sublimates (evaporates) into gas after being sprayed. As a result, there is no need for disposal of the mixture of media and dirt that occurs in traditional grit cleaning. Additionally, since it relies on thermal contraction and impact for detachment rather than abrasive action, it allows for safe cleaning while protecting the important base material. 【Features】 ■ No media residue left as dry ice sublimates into gas ■ No need for disposal of the mixture of media and dirt ■ Utilizes detachment through thermal contraction and impact ■ Safe cleaning possible while protecting important base materials *For detailed materials that explain the differences in effectiveness and cost comparison of cleaning media, click here.

We propose an effective solution for sites struggling with oligomer removal that adheres to the molding line of PET films, which require extremely high smoothness for applications such as optics and packaging. In the stretching process of PET films, oligomers precipitate in a high-temperature environment, firmly sticking to rollers, clips, and guides. This causes surface irregularities and scratches on the film, leading to reduced yield. Our dry ice blasting service utilizes the forces of thermal contraction and vapor expansion to clean the substrate without damage. Cleaning can be completed while the complex components remain assembled. 【Features】 - Utilizes the forces of thermal contraction and vapor expansion - Cleans the substrate without damage - Suitable for complex chains and guide rails - Cleaning is completed in a short time while remaining assembled *Here is the case study document that successfully improved the quality of optical PET lines and removed oligomers.

Embossing rolls that give various textures to synthetic leather, films, and paper. When dirt gets trapped in the fine sculptures that shape the design, it directly leads to molding defects. Dirt such as resin residue that adheres and becomes fixed in the grooves and patterns of the embossing rolls is extremely difficult to clean by hand. Our cleaning service uses ultra-fine pellets that penetrate deep into the patterns, safely peeling off and cleaning only the dirt through the effects of thermal contraction and vapor expansion. It can completely reproduce the original beautiful three-dimensional pattern without damaging the precise sculpted surface of the roll. 【Features】 ■ Ultra-fine pellets penetrate deep into the patterns ■ Safely peels off dirt using thermal contraction and vapor expansion ■ Does not damage the precise sculpted surface of the roll ■ Completely reproduces the original beautiful three-dimensional pattern *Here is the cleaning before-and-after documentation that demonstrates the complete restoration of complex embossed patterns.

Gas (resin) and residue that accumulate in plastic and rubber molding molds are the main causes of product dimensional defects, appearance defects, and reduced yield. Our dry ice service allows for cleaning and sanitizing while the mold is still mounted on the molding machine and in a hot (high-temperature) state. The ultra-low temperature dry ice instantly vaporizes and expands due to the heat from the mold surface, and through the synergistic effect of thermal contraction, it quickly detaches adhered gas components and stubborn release agents. This significantly reduces the time required for disassembling and cooling the mold, as well as for reheating, minimizing downtime in the manufacturing process. 【Features】 ■ Cleaning is possible while the mold is still mounted on the molding machine in a hot state ■ Ultra-low temperature dry ice vaporizes and expands due to the heat from the mold surface ■ The synergistic effect with thermal contraction quickly detaches adhered gas components ■ Significantly reduces the time required for disassembling and cooling the mold, as well as for reheating *Here is the case study material on increasing operational efficiency through online cleaning of molds.

Heat exchangers responsible for thermal management in plants and factories. Scale and dust adhering to plates and fins lead to a significant decrease in heat exchange efficiency and energy loss.
