| titleOfInvention | Method for producing compression spring member from copolyetherester |
| abstract | The present invention comprises the steps of preparing a preform from the copolyetherester composition; For the preform, applying a force to compress the preform in one direction to greater than 30% of its original size; And performing one or more compression cycles comprising releasing the force from the compressed preform, wherein the method comprises: 1) one or more alkylene diols; At least 50 mass% of at least one copolyetherester consisting essentially of a polyester hard segment consisting of repeat units derived from one or more aromatic dicarboxylic acids, and a soft segment derived from a poly (propylene oxide) diol; And 2) 0.01-2 mass% of nucleating agents. The manufacturing method of the compression spring member exhibits better consistency and reproducibility. An additional advantage is that the annealing step can be significantly reduced in time, or even omitted. The invention also relates to a compression spring assembly obtainable by the method, and a compression spring assembly comprising at least one such compression spring member. |
