Mechanical hanging scales, or spring scales, have been a fundamental tool for measuring weight and force for centuries. Their simple design, powered by the mechanical properties of springs, makes them a versatile, cost-effective solution for a wide range of applications, from agriculture to industrial use. While the concept behind these scales may seem straightforward, their manufacturing involves a precise and carefully controlled process that ensures accuracy, durability, and reliability.

Before delving into the manufacturing process, it’s important to understand the basic structure of a mechanical hanging scale. At its core, the scale consists of three key components:

The Spring: This is the critical part of the mechanical hanging scale. The spring is responsible for the scale’s ability to measure weight. As weight is applied, the spring stretches, and the amount of stretch corresponds to the amount of weight. The scale reads this stretch on a calibrated dial or digital display.

The Hook or Attachment Point: This is the part of the scale where objects are suspended. It is typically made of strong, durable materials like stainless steel to withstand the weight of heavy objects.

The Casing or Frame: The casing holds the spring and dial in place. It also protects the internal components and provides a housing for the scale’s calibration markings. The casing is often made of durable materials like plastic or metal.
