Asai Sangyo Co., Ltd. is engaged in the molding of carbon fiber reinforced thermoplastic resin (CFRTP). In hot stamping molding, carbon fiber woven fabric and thermoplastic resin film are laminated and hot stamped using molds capable of rapid heating and rapid cooling. This method allows for high-temperature molding that is difficult with methods using electric heating wires or steam. It is also capable of molding complex shapes that are challenging with thermoplastic prepregs. This method utilizes patented technology and is referred to as TAM (Thermo Assisted Molding) molding. The TAM molding method uses high-frequency electric current, resulting in less waste compared to methods using steam or heaters, and can heat the mold above the resin's melting point in a short time. Additionally, hybrid molding of continuous fiber CFRP and long fiber injection molding is a molding method that inserts hot-stamped continuous fibers into injection molding. It enables the integral molding of high strength, high rigidity, and complex shapes. **Features** [Hot Stamping Molding] - Direct electric heating method for molds - Material costs are halved compared to thermoplastic prepregs [Hybrid Molding] - Various shapes of metal products can be replaced with CFRP - Achieves strength comparable to aluminum alloys at half the weight

"Principle of the Electrostatic Oil Purifier EDC" Utilizing the fact that contaminants floating in oil become charged, the electrodes capture these contaminants. When classifying the particles dispersed and suspended in oil by their electrical properties, there are only three types: positively charged, negatively charged, and neutral. The positively and negatively charged particles are attracted to opposite electrodes (electrophoresis phenomenon). By inserting a pleated collector between the electrodes, a strong electric field is created, attracting neutral particles (dielectrophoresis phenomenon). The CleanTech electrostatic oil purifier EDC is designed to enable these two phenomena to occur simultaneously. It removes all types of waste that do not dissolve in oil, regardless of whether they are metals, non-ferrous metals, organic substances, or inorganic substances. It can also eliminate oxidation byproducts of oil that are difficult to remove with filters.

When classifying the particles dispersed or suspended in oil by their electrical properties, there are three types: positively charged, negatively charged, and neutral. The positively and negatively charged particles are attracted to opposite electrodes (electrophoresis), and when a pleated collector is placed between the electrodes, a strong electric field is created, attracting the neutral particles (dielectrophoresis). The EDC is designed to ensure that these two phenomena occur simultaneously. It removes all types of waste that do not dissolve in oil, regardless of whether they are metal, non-ferrous metal, organic, or inorganic.
