The "Spring Specification Change Check Sheet" for purchasers is a document that summarizes check items to provide cost benefits when requesting estimates from manufacturers based on designed drawings. Would you like to reconsider costs with appropriate specification changes for springs? For example… - Understanding manufacturing methods based on required specifications - Appropriate spring shapes needed for the specifications - Choosing wire diameters that match product weight - Preventing excessive specifications through appropriate material selection - Understanding the necessity and types of surface treatment and plating, etc. By re-evaluating the five important points in spring manufacturing: "manufacturing methods, shapes, materials, wire diameters, and surface treatment/plating," there is potential to further reduce costs for the springs currently in use and for developed products. *For more details, please refer to the PDF available for download.
