The production of spring is inseparable from the spring machine
Springs are of great significance to engineers, especially to mechanical design engineers. Because springs can often be used to make some simple mechanical storage or release devices. Similar to some fasteners, various springs are almost indispensable in various mechanical products.
In mechanical products, springs are used in a wide range of applications, with many types, shapes and sizes. There are clock springs as small as a hair, low-cost ball-returning springs and pen springs, as well as large-sized stepped springs used in various means of transportation, and some precision springs used in the aerospace industry with high quality requirements.
