Application of Variable Force Springs

Point-Of-Purchase
There are two types of flat coiled springs be used in point-of-purchase, they are constant force springs and variable force springs.
when the width of the shelf pusher is below 20mm and needs small tension, we usually chose the constant force.
besides, we often use the variable force springs.
variable force springs can supply variable tension as the stuff in the shelf pusher increase or decrease, so as to have a stable strength.
Curtain Decorating
Variable force springs also are wildly used in curtain decorating.
Its smooth tension wins many clients’ praise.
Different curtain size match different specification of variable force springs.
