THE COMPLETE GUIDE TO SPRINGS
When you’re looking to buy springs, knowing what’s out there for you to choose from can help you understand what you need for the job at hand. The three general categories of springs are used for different applications, and the size, material, coating, and end types will all have an impact on efficiency and durability. Choose the wrong spring for the job and you’ll face costly downtime and frustration. To increase your spring knowledge and make the right choice, check out this complete guide.
The compression spring offers resistance when pushed down with a compressive force. The active coils store and release energy. The load compresses it and makes it shorter while the spring attempts to push back to get to its original length. This energy-efficient open-coil helical spring is the most commonly used metal spring. It can be conical, hourglass, or barrel shaped and custom designs are common. It’s typically fitted into a hole or placed over a rod. It can be wound in a left-hand or right-hand direction and can have varying amounts of coils, which are counted from tip to tip. It can have a closed end, ground ends, or open ends.
Compression springs are found in virtually endless applications, from tiny medical and instrumentation devices to engines, electronics, major appliances, and lawn mowers.
The helical extension spring performs in the opposite way of the compression spring by extending instead of compressing, and the stress levels are lower than for the compression spring because it doesn’t have a solid stop that prevents overloading. It has loops, eyes or hooks on each end in order to allow the application of a pull force. These ends are attached to other components, and when these components move apart, the spring tries to get back to its original form by bringing them together again. Initial tension keeps the coils closed, which must be overcome before the coils begin to open. The unloaded position is called the free length, while the fully rated extension is known as the extended length, and the full extension is the maximum load. This type of spring not only absorbs and stores energy, but it also creates a resistance to a pulling force.
It’s used in many applications, such as farming machinery, children’s toys, trampolines, garage doors, brakes, and pliers.
The torsion spring is used to store rotational energy or apply a torque. As with the extension spring, the ends of the torsion spring are attached to other components. The difference is the spring tries to push back the components to get back to its original shape while the components rotate around the center of it rather than through extension. It statically holds a mechanism in place or stores and releases angular energy. The torsion spring is typically mounted around an arbor or shaft and has to be supported by at least three points.
Torsion springs can be found in clothes pins, window shades, clipboards, hinges, ratchets, and many other applications.
MATERIALS, COATINGS, AND SURFACE TREATMENTS
Depending on your application, you can choose from a variety of materials, coating, and surface treatment options. Material selection ranges from ferrous and non-ferrous metals, stainless steel, and alloy steels. Material can also any number of different shapes including round, square, triangular, hexagonal, or just about any shape you can imagine.
Your springs can also be treated with electropolishing, tumbling, shot peening, electroplating, electroless plating, or chemical coatings. The materials you choose will have an impact on the efficiency and durability of your spring while the coating option you choose will be based on the amount of corrosion protection you require and the surface hardness or wear resistance you need.
THE IMPORTANCE OF HIGH QUALITY SPRINGS IN THE AUTOMOTIVE INDUSTRY
From compression springs in your vehicles’ valves, suspension, and seating and door hardware to coil and compression springs in the transmission, those in the automotive industry know how vital the various types of springs are in the manufacturing of vehicles. However, just putting any cheap spring into the production of your vehicles isn’t good enough. With the automotive industry being so competitive and so much importance being placed on safety, efficiency, and reliability, your only option is to use high quality springs.
Here are a few reasons why high quality springs are vital to the automotive industry.
To be the best in the automotive industry, your vehicles need to perform at an optimal level. Low quality springs won’t be able to withstand the pressure placed on them or the driving conditions they’re put through as well as high quality springs. Customers depend on their vehicles to work well in extreme weather, on uneven roads, and on long drives. If the springs can’t stand up to these conditions, providing a smooth ride from start to end, your customers won’t be satisfied with the product they’ve purchased from you.
Low quality springs can be created due to poor manufacturing, an inaccurate design, the wrong material type for the application, or even the wrong size type of spring. Any of these factors can result in you purchasing springs that won’t allow for optimal performance. When you’re searching for a spring manufacturer, consider these factors before you make a purchase. Money isn’t everything.
Naturally, no customer wants to worry about his or her vehicle breaking down on the way to work, on a road trip, or when he or she runs over a pothole. They don’t want to have to go to the mechanic’s every other week to have their springs replaced because their vehicle isn’t functioning efficiently. When they buy a car from you, they expect to have no problems for a long time. Sure, they’ll have to get oil changes and get the engine checked out occasionally, but they certainly don’t want to be spending all their time and money fixing car parts that should be durable. They want to be able to rely on their vehicles.
When you’re not using high-quality springs in your manufacturing process, you’re not creating cars that are going to last for the long run. Low quality springs will wear out, rust, or break under pressure—and it’s going to happen too quickly.
Manufacturing high quality vehicles is not only important to your company, it’s important to your customers. When the springs and other components in your vehicles provide superior performance and durability, your customers will be satisfied with their purchases. And this customer satisfaction can only be good news for your reputation. The last thing you want is hundreds of poor reviews being posted by unhappy customers because the springs you used were poor and weak. This can greatly hurt your future sales.
CHOOSE THE RIGHT MANUFACTURER FOR HIGH QUALITY SPRINGS
Every spring you place inside the vehicles you manufacture should be strong and durable. Quality is vital in the automotive industry—to your reputation, to your profitability, and to your customers. Don’t risk losing valuable customers and future sales to save a few bucks up front. It’s just not worth the damage you could be dealing with in the end. Make sure the spring manufacturer you choose focuses on quality—not just price.
Wire form applications
Wire forms have a wide range of available designs, with the only limitations in the imagination of the designer and the skill of the machine setter. They have a wide range of applications. Some of them are:
- Wire forms for electrical applications: Wire forms are used in many electrical applications, some of the common are for tin plated to bend clips that are used to hold equipments and some wires in electrical applications.
- Wire forms for light fixtures: One of the most common industries that use CNC wire forming is lightning industry and can meet tight tolerances.Light fixture wires are also common wire forms.
- Manufacturing of battery contacts: Some battery contacts are designed as wire form springs and some are designed as stampings that are made from sheet or strip materials. These are quick and have inexpensive applications to run.
- Safety pins and mousetraps: Safety pins are also a form of wire forms; they are an example of a simple wire form.
