Please consult with us. We overturn the conventional wisdom of plastic! Environmentally friendly, high value-added foaming technology.

The "Supercritical Inert Gas Foaming Technology" is a high-value-added micro-foaming technology that considers both people and the environment. It does not have the explosiveness or flammability of hydrocarbon-based physical foaming agents, so there is no need to make the equipment explosion-proof. It is also free from the toxicity of chemical foaming agents and has no residual effects, making it excellent for recycling. Our company provides comprehensive support from raw materials to the entire molding equipment and the development of the molding process. Additionally, our foaming molding machines come standard with extrusion molding and RIM molding. If you are considering foaming molding, please feel free to contact us. 【Features】 ■ The foaming agent is non-explosive and non-flammable, eliminating the need for explosion-proof equipment. ■ It has a low global warming potential, taking the global environment into consideration. ■ It is non-toxic and has no residual effects, making it excellent for recycling. ■ It is capable of forming fine bubbles of several micrometers. ■ It can also be applied to foaming of crystalline resins, which were difficult to foam at high ratios with conventional methods. *For more details, please refer to the PDF materials or feel free to contact us.

RIM foaming using inert gases. A technology that contributes to environmental conservation, enabling foaming of products that were previously unsuitable for foaming and creating reaction injection molded products that have never existed before.

**Characteristics of Supercritical Inactive Gas RIM Foaming Molding** - Bubbles are fine (a few micrometers) - High bubble density (over 10^9) - Weight reduction can be achieved with similar physical strength - Possesses high thermal insulation properties (low thermal conductivity) - Good high-frequency characteristics (low dielectric constant) - Fine-grained elastomer foaming - Good surface properties (control of skin layer is possible) - Control of independent and continuous bubbles is possible - Difficult to generate defects like shrinkage, allowing for flexible structural design of molded products such as ribs - Can shorten molding cycles - Does not use environmentally harmful foaming agents - No risks associated with explosive atmospheres - The cost of foaming agents is low

• Injection Molding Machine

Foamed sheets made from biodegradable resin PLA (polylactic acid) that are produced using environmentally friendly methods. They can be used for food trays, agricultural products, medical supplies, packaging, and cushioning materials.

Plasteco Co., Ltd. has consistently focused on "plastic production that considers people and the Earth" since its establishment. Through our unique technology that uses a safe inert gas with a low global warming potential to foam resins, we conduct research on plastic products and manufacturing methods that address environmental and resource issues, as well as the development and manufacturing of related equipment. With this technology, we have successfully achieved high-density foaming of plant-based biodegradable resins like PLA (polylactic acid), which were previously difficult to foam. Our foamed plastics are carbon neutral, derived from non-petroleum sources, and do not generate excess CO₂ during manufacturing and disposal processes, making them advanced materials that can be safely used in the future. Our foamed sheets are 100% biodegradable and do not use chemical foaming agents. Amid growing global concern over plastic waste, they can be applied in various fields as new environmentally friendly products, including food trays, packaging materials, and medical products. We have vacuum forming equipment and molds for testing, allowing for prototyping from sheets to formed products.

Renewed with a new model! This is a gas supply device capable of precisely and stably supplying inert gases necessary for foam molding, such as carbon dioxide (CO2) and nitrogen (N2).

【Renewal & New Model Launch!】 - Smaller and lighter than the previous model - Equipped with a 12-inch large screen touch panel - Precise control of gas supply volume is possible through data linkage with various molding machines Foaming with CO₂ or N₂ experiences significant changes in bubble diameter and foaming conditions due to minor fluctuations in supply volume. Additionally, traditional pump methods using pressure control have seen supply volume fluctuate due to pressure changes at the gas injection point of the molding machine. Plasteco's supercritical inert gas quantitative supply device maintains a constant supply mass and automatically adjusts the supply pressure to follow the pressure at the supply point, enabling precise control of the supply volume at all times and achieving uniform and fine foaming. Furthermore, by precisely controlling the gas addition amount through data linkage (optional) with extrusion and injection molding machines, stabilization of foaming ratios and reduction in the weight of molded products become possible. It can accommodate a wide range of applications, from small flow rates for small molding machines to large flow rates for large molding machines, as well as RIM molding and other uses. It also supports flow control, high-pressure compatibility, and other options, making it suitable for various applications.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

SPACECOOL Inc., which researches, develops, and sells the radiation cooling material "SPACECOOL" that releases heat into space to achieve zero-energy cooling, will exhibit at the "Jumbo Surprise Exhibition," a comprehensive trade fair for electrical materials and housing equipment, held at Tokyo Big Sight from April 17 (Friday) to April 18 (Saturday), 2026, and at Intex Osaka from April 24 (Friday) to April 25 (Saturday), 2026. This material is a new technology that enables zero-energy cooling by converting heat into infrared radiation and releasing it into space, without using any external power. By implementing it in outdoor air conditioning units and outdoor electrical equipment, it helps suppress internal temperature rises, contributing to stable operation of devices and reduction of air conditioning energy consumption, and is being recognized as a new carbon-neutral technology. Its energy-saving performance has been acknowledged, and this material received the 2025 Energy Conservation Award. When you visit the venue, please stop by our booth. Our booth number is 972 (common for both Tokyo and Osaka). We will continue to work towards expanding the social implementation of SPACECOOL to contribute to the stable operation of outdoor equipment and air conditioning units, as well as to reduce air conditioning energy consumption and CO2 emissions.
