Steps in Spring Manufacturing

The first step in spring manufacturing is to determine the type of material that is going to be used. Typically, springs are made from wire that is around 5/8″ in diameter. The metal blank is then pushed over a support block to a grooved head that deflects the wire and forces it to bend. Different types of metals create different levels of compressibility. CNC programmable machines are used to complete the design process.

The Process Takes Several Hours To Complete And Is Highly Precise

The next step in spring manufacturing is to determine the type of spring. Different springs require different manufacturing processes. If you need a mechanical spring for telecommunications, for example, you’ll need a different type than if you need a spring for a car or refrigerator. A spring manufacturer that specializes in compression and torsion springs can help you find the right one. Check out the following directory to find the right company for your needs.

The wire used in coiling is either at room temperature or heated. This is done to make the wire more flexible. Thick steel bars can be used in coiling. Heat treatment helps to prevent metal fatigue, which can cause cracking during use. Then, the spring is set to function correctly at a specified length and pitch. Some manufacturers will repeat this process multiple times. The process takes several hours to complete and is highly precise. For larger springs, these coiling machines are highly automated.

Another process that can be used to finish springs is electroplating. During this process, a thin layer of metal is applied to the spring’s surface. Electroplating involves a process that uses electrical currents and chemicals to bond the metal to the spring’s wire. These platings can enhance corrosion resistance, strength, and physical properties. For example, copper and gold plating lend increased electrical conductivity, while nickel and cadmium provide a chrome finish.
