Why are variable force springs used in shelf thrusters?

Variable force springs are very common in the point-of-purchase or POP industry, especially in shelf pushers. Variable force springs provide variable force to precisely match increasing or decreasing force requirements, propelling the product horizontally forward. Due to their wide applicability, these springs can be seen in the tobacco, cosmetic, electronics and medical industries. So why use variable force springs in shelf thrusters?

1. Inventory Control

Variable force springs are commonly used in trays that push products forward in a controlled manner. Variable-force springs in the push-in trays aid product fronts, so the shelves are always well-stocked. These trays allow for more organized store inventory and help track inventory needs. This is even more critical in today’s COVID-conscious environment.

2. Product integrity

Variable force springs are designed around the weight of the product they push. This ensures that the product is never slammed or damaged when it is selected. Variable force springs allow most products to be pushed with a consistent force regardless of item weight. At Qianye Precision, we understand the importance of displaying products in high-end retail spaces. We take this into account in every design.

3. Customer Satisfaction

Variable force springs make shopping easier for consumers because products are displayed in a more organized and aesthetically pleasing manner. Products include cosmetics, nutraceuticals and pharmaceuticals, beverages, food, and anything suitable for retail display.

In terms of the design of the variable force spring under consideration, because the force of the variable force spring is variable, the force changes when the spring is extended or retracted. For most retail applications, the spring works in the retracted direction. Unlike constant force springs, these springs are not tightly wound or uniform in shape. Coil size varies throughout the spring body. This change in coil size enables the variable force spring to output a variety of forces during its working extension.

The most common material for variable force springs is Type 301 stainless steel. These variable force springs can handle a variety of environments required by retail customers, including ambient storage areas and refrigerated and frozen packaging areas. The standard finish for products is deburred edges, but you can request a “rounded” finish for smoother edges. Remember that a low design estimate will lead to early failure, and a high design estimate will make the spring larger and more expensive than necessary. Qianye Precision can help determine the appropriate material size to provide the required load when installed into your installation space.
