Food grade compression spring is a helical spring that is under pressure. Food grade compression springs are generally wire coiled at equal pitches and have a fixed wire diameter.

Springs are generally of equal pitch. The shapes of food grade compression springs are: cylindrical, conical, convex and concave, and a small amount of non-circular shapes. There is a certain amount of space between the rings of food grade compression springs. Gap, when subjected to external load, the spring shrinks and deforms, storing deformation energy.

food grade compression spring provides resistance to external load pressure. Food grade compression springs are generally wire coiled at equal pitches and have a fixed wire diameter. The food grade compression spring utilizes multiple open coils to provide resistance to external load pressure. That is, they push back against external pressure.
