When solid drinks such as milk powder and whey protein are added into a cup and shaken with water, it is easy to agglomerate or melt incompletely. Springs can help solid drinks melt and prevent caking.

Extended data structure classification

According to the mechanical properties, springs can be divided into tension springs, compression springs, torsion springs and bending springs, disc springs, ring springs, leaf springs, spiral springs, truncated cone scroll springs and torsion bar springs, and can be divided into cold spiral springs and hot spiral springs according to the manufacturing process. Ordinary cylindrical springs can be made into various types according to the load because of their simple manufacture, simple structure and wide application. Generally speaking, the spring manufacturing materials should have high elastic limit, fatigue limit, impact toughness and good heat treatment performance. Commonly used are carbon spring steel, alloy spring steel, stainless steel spring steel, copper alloy, nickel alloy, rubber and so on.

The manufacturing methods of springs include cold coil method and hot coil method. Generally, the diameter of spring wire by cold rolling method is less than 8 mm, and that by hot rolling method is greater than 8 mm. Some springs must be punched or shot peened after being made, which can improve the bearing capacity of the springs. ?
