The process of making springs goes through several processes to get the final product. These include: Calculation, drawing, manufacturing process, checking of the manufactured product, heat treatment, testing and packaging of the same. Depending on the choice of spring model, the manufacturing process itself also depends. Based on the place of installation and the influence of other factors, we choose the right material for the production of the spring. Through the manufacturing process itself, the most important task is to get a QUALITY product.
In order to make springs, it is necessary to define and calculate the appearance of the spring, according to the appropriate parameters. Then comes the preparation of the material and the machine, where the spring is made. For the production of springs, we use a wire diameter from 0.2mm to 25mm.
The grinding process is the next important step in spring production. The grinding machine is automatically loaded by means of feeding devices designed for large batches. By grinding the spring, springs are obtained that are ideally straight and vertical, so that deformations do not occur during operation.
In order to reduce unwanted internal stresses, which can negatively affect the properties of the spring, the springs are heat treated after the winding process. The background to this is the structural changes in the wire that occur when the spring is wound. Depending on the material, this process takes place between 240 and 650 degrees Celsius. In Opruga plus, heat treatment takes place in a chamber furnace.
In order to prevent deformation of the spring during its working life, the springs are tested based on several parameters. This means that a predicted load is applied to the material used beyond the elastic limit in order to predict the subsequent loss of strength and length. The springs are machined in a hot or cold setting process on different systems to better withstand customer requirements that match the application scenario.
Special packaging plays an important role in many processes in the world of technical springs. They serve to protect the springs or to improve the handling of the parts. The springs tend to get tangled and tangled. Special packaging can prevent this.
- Packing in boxes
- Packing in zip bags
- Packaging in stretch film
- In special boxes for classification
