The secret is room temperature curing silicone. There are no restrictions on the master model. *Demo and samples are available.
It is possible to achieve high strength and high heat resistance prototypes without molds at low cost and with short delivery times. The CAST&CAST method is a contract processing service that has developed and introduced a groundbreaking technology for producing nylon products through vacuum casting. By using the only patented thermoplastic casting material, we can provide excellent nylon products. Master models can be accommodated from light-curing, machining products, or existing physical items. We can cater to various fields, including automotive parts. Based on our extensive experience, we will make optimal proposals to our customers. 【Features】 ■ Excellent heat resistance, impact resistance, airtightness, chemical resistance, and wear resistance ■ Significant cost reduction and shortened delivery times without the need for molds ■ Alternative to metal parts ■ Excellent mechanical strength, suitable for practical testing 【Cost Comparison】 (Nylon casting / machining / injection molding with molds) ■ Production quantity 1-3 units: ○ / ◎ / × ■ Production quantity 4-30 units: ◎ / △ / × ■ Production quantity over 30 units: △ (※) / × / ○ ※ Even with mold expansion, there may be cases where costs are lower than with molds.

basic information
Nylon casting is a method that uses silicone rubber molds as an alternative to metal molds to cure resin. The nylon material used in injection molding is a thermoplastic resin with high viscosity, so it is necessary to apply pressure to ensure the material reaches every corner of the mold. However, silicone molds cannot apply injection pressure like in injection molding, which limited the types of resins that could be produced to thermosetting resins. With the CAST&CAST method, the use of liquid materials eliminates the need for pressure during pouring, making it possible to cast nylon, which is a thermoplastic resin. 【Physical Properties of Nylon Cast Products】 (Carbon filler 20% / Glass filler 30% / Test/ISO) ■ Hardness (Shore D): 81 / 82 / 868 ■ Flexural modulus (Mpa): 6200 / 5200 / 178 ■ Tensile strength (Mpa): 88 / 89 / R527 ■ Heat distortion temperature (0.45Mpa) (°C): 230 / 230 / 75B ■ Impact strength (Izod V notched) (KJ/m²): 50 / 45 / 180 ■ Thermal conductivity (W/mk): 0.22 / 0.22 / BS874 *For more details, please refer to the PDF materials or the official website, or feel free to contact us.

Company information
Niko Giken Co., Ltd. primarily engages in the manufacturing of various "research and development prototypes" and has built up expertise in producing a wide variety of small quantities of resin products using 3D modeling technology, machining technology, and general casting technology for thermosetting resins since its establishment in 1984. Based on this comprehensive resin processing technology, we have established a unique technology for "casting nylon, specifically nylon 6, which is thermoplastic." Since 2009, we have been developing our nylon casting business centered on technology development, accumulating achievements while responding to customer demands, and received certification as "Composite Nylon Casting Technology" under the "11th Kawasaki Manufacturing Brand." In 2016, to further enhance and systematize the strengths of our unique technology, we established a development headquarters at the "Kawasaki New Industry Creation Center (KBIC)." In 2017, we began brand development under the name "3NI-NYLON." We are collaborating with the "Ikuta PBF Factory," which is equipped with large high-end 3D printers. We are conducting research and development of materials, equipment, and systems to solve QCD challenges required for small-batch production across various fields.
