〇 Punching Process This is a processing method where the material is sandwiched between the male mold (punch) and female mold (die), and then punched out using a press machine to obtain products or parts with a specified shape. Compared to machining processes that involve cutting the material, this method has the advantage of enabling mass production in a short time, which is why many thin products and parts are produced using this technique. 〇 Thermosetting Resin Laminates The thin plastic sheets for punching processing provided by Rishou Industry are referred to as "thermosetting resin laminates" according to JIS standards. These are made by stacking a specified number of base materials (called prepreg) that have been impregnated and partially cured with thermosetting phenolic or epoxy resins onto paper, cloth, or glass fabric, and then pressing them under high temperature and high pressure. Unlike plastic sheets made by extruding or pouring thermoplastic resins into molds, these are fiber-reinforced plastics (FRP) that are enhanced with fibrous base materials, providing excellent mechanical strength and resistance to punching processes. 〇 For Cost Reduction and Production Efficiency We would like to remind you that there are plastic sheets that can withstand press punching, and we encourage you to consider these for cost reduction and production efficiency.

Glass fiber reinforced plastic (GFRP) not only has excellent electrical insulation properties but also possesses heat resistance, mechanical strength, and chemical resistance, all while being a type of plastic. 【Features】 - The bending strength of a 1mm thick specimen is 450 megapascals, and the tensile strength is 350 megapascals. - The heat resistance temperature is 130°C. *Even after heat treatment at 180°C for 2 hours, there is no significant change in strength or dimensions. - The insulation resistance per 1mm of material is 28,000 volts. (JIS K 6911) - This plastic exhibits extremely low discoloration and dimensional changes due to aging. - Excellent chemical resistance to oils, solvents, acids, and alkalis. 【Applications】 - Machined into parts that require mechanical strength. - Areas where metals are unsuitable. - Areas requiring electrical insulation, thermal insulation, rust prevention, corrosion (electrolytic) prevention, and magnetization prevention. By replacing other materials you have been using with this, you can achieve improved functionality and cost reduction! *For more details, please download the catalog or contact us directly.

In addition to excellent electrical insulation properties, it possesses heat resistance, mechanical strength, and chemical resistance, despite being made of plastic. Utilizing these characteristics, it is often machined into parts that require mechanical strength and installed in places where metals would be unsuitable, such as areas needing electrical insulation, thermal insulation, rust prevention, corrosion (electrolysis) prevention, and magnetization prevention. Given its reasonable price, it offers a well-balanced combination of excellent properties, allowing for potential improvements in functionality and cost reduction by replacing other materials previously used, depending on the application. Furthermore, with a specific gravity of about 1.8, for example, in situations where stainless steel (specific gravity ≈ 8.0) parts are used for rust and corrosion prevention, replacing them with this material can achieve nearly 80% weight reduction.

It is an insulating tube that combines the strength of resin pipes with the oil-impregnability of pressboard.

These are custom-made bolts and nuts designed and manufactured according to your requests. We offer types processed from "laminated rods" with a standard diameter of up to 20mmφ and types processed from "laminated pipes" that can standardly accommodate sizes from M10 to M100. We may also be able to accommodate special sizes, so please feel free to consult with us.

【Features of Ricocalm】 ○ Excellent vibration damping effect η = 0.41 ○ Excellent sound insulation TL = 30dB (4000Hz) ○ 40% weight reduction compared to steel plate-based damping materials ○ Obtained "Flame Retardant Covering Material" certification from the Nippon Kaiji Kyokai (ClassNK) ○ Obtained "Primary Deck Covering Material" certification from the Nippon Kaiji Kyokai (ClassNK)

Glass cloth epoxy resin laminates are machined into various shaped parts and are applied in areas where metals are unsuitable, such as where electrical insulation, rust prevention, corrosion (electrolysis) prevention, or magnetization prevention is required. With the addition of L-shaped materials to the lineup, the variety of machining options will expand, and we hope that glass cloth epoxy laminates will be adopted in more industrial fields.

"Woodlight" is a type of plywood or laminated veneer lumber (LVL). It is made by impregnating thin sheets of wood (veneer) that have been peeled in a "katsura" style with phenolic resin, and then pressing them together under high temperature and high pressure in a specified number of layers. Recently, cellulose nanofibers have been gaining attention, but "Woodlight" is a unique FRP board reinforced with natural wood, meaning it is made from full-size cellulose.

Recently, cellulose nanofibers have been gaining attention, but "Woodlight" is a unique FRP board reinforced with natural wood, meaning it is made from full-size cellulose. ■ Features 1. There is no degradation in its electrical and mechanical properties, whether in oil or air. 2. Even after long-term immersion in water, the recovery of insulation resistance is quick, and unlike ordinary plywood, there are no concerns about delamination, warping, twisting, or cracking. 3. Compared to insulating wood injected with natural wood oil or paraffin, it not only significantly outperforms in electrical, mechanical, and water resistance properties but is also stable due to its uniform composition. 4. It is rich in moisture resistance, heat resistance, and chemical resistance. 5. The unique appearance created by the wood grain and layers is further enhanced by a buff finish, giving it a more elegant luster.

The "Industrial Winding Core" is a core made of thermosetting resin "FRP" reinforced with fibrous substrates such as paper and glass cloth. It features excellent mechanical strength, heat resistance, chemical resistance, and dimensional stability, contributing not only to increased production efficiency but also to the reduction of defects and waste. It is being showcased at the Converting Technology Comprehensive Exhibition. 【Features】 ■ Many applications with high-performance films and metal foils ■ Lighter than metal winding cores ■ Superior recovery from deflection compared to metal winding cores ■ Service life can be extended with proper maintenance ■ Custom options available *For more details, please refer to the catalog.

Paper-based phenolic resin laminated sheets are thermosetting fiber-reinforced plastic sheets that are highly regarded as excellent insulating materials. PS-1571 is designed to have a surface resistivity of approximately 10^6 ohms/sq. This surface resistivity allows for relatively quick dissipation of static electricity without causing intense discharges (sparks) when in contact with charged electronic components.
