The elastic piece is the only metal component in the thin film switch, which is widely used. At present, the use of elastic pieces in many products is rather confusing, especially in flexible circuits, which are only used as elements to supply hand feeling (tactile feedback), resulting in many defects in the function of the membrane switch, and even the membrane switch loses its due role.
The metal shrapnel is a kind of elastic element widely used in the machinery and electronic industries. When loaded, the metal shrapnel can undergo large elastic deformation, converting mechanical work or kinetic energy into deformation energy. After unloading, the deformation of the metal shrapnel disappears and returns to the original state, converting the deformation energy into mechanical work or kinetic energy.
The production of metal shrapnel is a special process of processing materials (metal or non-metal) into parts (or semi-finished products) through cold stamping of stamping dies. Stamping is a pressure processing method that uses a die installed on a press to apply pressure on data at room temperature to make it separate or plastically deform, and then obtain the required parts.
Now hardware shrapnel is widely used in electronics, electrical appliances, it, communications, furniture, advertising, arts and crafts, clothing, luggage, sports equipment, cars, daily use, outdoor, construction and other industries.
