A spring is an important part of many devices around us. If you are building a model or you are carrying out experiments or manufacturing a device, you will find yourself in need of different springs. While making your own spring from a paper clip might sound quite easy, this DIY spring cannot be taken up as an example of a spring manufacture. The requirement of springs varies from one job to another and hence you need to buy springs that exactly match your needs. There are a few things you should look for in a spring before you start using it.
Type of Spring
The type of spring you need will depend on the purpose for which you require the spring. There are numerous types of springs classified on the basis of the shape, operation and purpose. If you are not sure about the type of spring you require, you can contact a local spring manufacturer and explain your requirements. They will be able to help you choose the right spring for your device. Once you know the type of spring, you should look at the companies that manufacture your required spring. Customspring.ca manufactures a variety of wireforms, spring clips, mechanical springs and precision springs.
The material of your spring should be decided depending on your special requirements. For instance, if the spring will be placed in an environment where it has to face high temperatures all through or an environment where corrosive acids will be present, you should look for the best material with high temperature resistance and corrosion resistance. The most common type of material is steel. You can find stainless steel springs in various pre-configured sizes readily available. There might also be springs made from ferrous steel, carbon steel and other non-ferrous materials too. Alloys consisting of all or any of chromium, copper, tin, silicon can also be used to manufacture springs.
The size of the spring is quite important. Mechanical springs are commonly available between 0.005 inches to one and half inches. The force the spring exerts is linearly proportional to the length and size of the spring. You should calculate the required size depending on the force you expect. Some of the sizes will be readily available and if you require a size that is not commonly found, you can order a spring for the specific size from manufacturers who produce custom springs.
Load Bearing Capacity
The load bearing capacity of springs vary from one spring to another. Even springs made from same materials in same thickness can have different load bearing capacities. The load bearing capacity or the tensile strength of the spring will decide if it is suitable for use in your required environment.
The cost of the springs depends on a number of factors. Stronger springs do not translate directly into higher cost. If you require specially treated springs to resist heat, cold or water, you will need to shell out more. You will be required to buy springs in bulk, especially if you are ordering custom springs. You can get quotes from 2 or more companies before you settle on one.
