The casting process using Nyrim is also known as RIM (reaction injection moulding). TECARIM, the commercial name used by Ensinger, includes a product group containing tough, highly resistant polyamide 6 block copolymers manufactured using this reactive casting process. The casting process is done without additional pressure.
Cast parts with weights between 0.5 kg and 35 kg can be produced, parts with weights below 1 kg can be realized with multicity moulds. The process is especially well suited for large-volume moulded parts, in particular if they are constructed with thick walls or major differences in wall thickness. Producing parts using a TECARIM process is especially useful if the quantity is too high for machining, thus, making it uneconomical, while injection moulding cannot be used due to the dimensionally large part sizes, wall thickness or large varience of the wall thickness as well as small production numbers.
Nyrim products have a unique profile of properties with a wide range of variation in impact resistance, stiffness and strength at low temperatures, primarily influenced by the percentage of elastomer.
